4 Types of Lubricants And How to Use Them
A Fluid Bed Dryer is designed for drying powders, crystals, and medium-sized pellets quickly and uniformly. There are several uses for the Fluid Bed Dryer in the pharmaceutical and bulk drug industries as well as in dyes and chemicals and Phyto-Chemicals.
In the pharmaceutical industry, a Rapid Dryer (also known as a fluid bed dryer) is used extensively to decrease the moisture content of medicinal powder and granules. Wet granules must be dried before compression into a tablet may take place, as well as to adjust the viscosity and stickiness of the substance. As the last step before compression into tablet form and packing, drying is usual.
Perforated beds of wet solid particles are punctured by high-pressure hot air in the fluidization process. An airstream is used to raise and suspend the dripping sediments from the tank's bottom (fluidized state). Direct contact between the moist substance and the hot gases results in heat transfer. The drying gases pick up the evaporated liquid and carry it away. Exit gas may be partly recycled in order to conserve energy.
Drying wet grains, crystals, or coarse materials is made easier using the Fluid Bed Dryer. Passing high-speed hot air through a bed of material to be dried causes it to become fluidized and so dries more quickly.
The induced draught and fresh air are created by a blower on the dryer's exhaust side that uses no negative pressure concept. From the bottom of the product container, a stream of heated, filtered air is emitted. The air distribution plate and the Dutch sieve are included with this container. The turbulence in the product container is created by passing the air stream through the bed of the substance. As a result of fluidization, heated air surrounds each particle, causing rapid and even heating and drying. Particles can't escape the machine because of the top-mounted filter bags.
There is a good chance the ordinary person has never heard of them. Fluid bed dryers, on the other hand, have made a name for themselves as versatile and trustworthy processing equipment in the bulk processing industry.
The Carbide Insert for Cast Iron Pharmaceutics Industry's reliance on Dryers
Despite the fact that fluidized bed drying may be utilized in a wide range of sectors, pharmaceuticals have perhaps benefited the most from its usage. It is possible to consistently reduce the moisture content of pharmaceutical granules and powders by utilizing a fluid-bed drier. With the introduction of fluid bed drying technology, drying periods have been reduced significantly and equal drying conditions have resulted in a consistent finished product.
Fluid bed dryers are ideal for drying a wide range of items, but pharmaceutical products in particular. The system controls incoming air temperature to ensure that moisture evaporates off the granule's surface at the right pace. A high input air temperature might lead to a surface crust that inhibits deeper tungsten carbide inserts moisture from being transferred to the surface, slowing rather than speeding the drying process.
Principle of a Rapid Dryer:
A perforated bottom of a vessel holding a bed of particle solids or wet granules allows high-pressure hot air (gas) or ambient air to flow upward upwards better known as a fluid bed drier. The granules/particles stay suspended in a stream of hot air because the velocity of hot air is greater than the settling rate of the granules/particles. A fluidized state describes this state of affairs. Every granule/particle is thoroughly dried by the heated air that surrounds it.
Structure:
Vertical and horizontal stainless steel or plastic FBD fluid bed dryer machines are available. Batch drying is done in a vertical unit, whereas continuous drying is done in a flat unit. The material is loaded and unloaded into a removable vessel at the dryer's bottom. The perforated mesh allows hot, high-pressure air to travel through the vessel. The dry material is collected by placing bag filters on top of the tank.
Process:
At the bottom of the dryer, a removable container holds the material to be dried. The hot air is brought up through the prefilter and into the chamber through the heaters. The simultaneous operation of a fan is also permitted. An increase in air velocity causes particles to move in a turbulent manner known as fluidization.
All the while, the air stream is filled with very tiny granules and particles. When the frictional drag on the granules/particles is equivalent to the force of gravity, a condition of pressure is attained. Due to the high velocity of air, the particles are able to climb to the top of the air stream; this is known as fluidization.

Heard of a quote 'Old is Gold', this describes the importance of the print industry well. The large companies tend to invest in print media to expand their business and to reach large masses.
We see different types of advertisements every day, as we are surrounded by many companies that are trying to sell their products to the audiences. Advertisements are done to persuade people to use a particular product or service, the printed advertisements which are present around us use different technologies and types of printing, the Flexo Printing Machine Manufacturers in Mumbai is used TNMG Insert to print the large flexes for promotional purposes, to print on to the packaging of the products and last but not the least for the publication. The Flexo Printing is highly used by the companies as it is durable and can also be done within the economical price range.
The other technique which is used for publication and packaging is gravure printing, for this particular printing, the Rotogravure Printing Machine Manufacturer in Mumbai is providing the machines at affordable prices. This printing technique is used in the magazine and directories. Ever wondered how the cigarette cartons have such a finishing print on to them? It is the rotogravure printing technique that is being used by the tobacco manufacturing companies, which gives such a fine quality print on to the products.
The mechanism used in gravure printing is that there is a cylinder in the machine in which the image is engraved, the surface is made up of copper, metal or zinc, the finish of the surface is very smooth so that it will give the finest quality of printing on all the products, the ink used in this technique is a quick-dry, so the product is ready for transporting just after the packaging is done, there is no need to wait for the ink to try.

How to Manage Cutting Tool Inventory in a Small Job Shop
Some CAM systems offer toolpath strategies that ensure a consistent load on a tool by controlling its engagement angle with the workpiece. Using this approach, the tool isn’t driven into internal corners where its engagement angle (thus, the force exerted upon it) greatly increases.
Delcam has recently developed a roughing strategy designed for solid carbide tools it calls Vortex that combines consistent tool engagement with a step-cutting strategy already available in the company’s PowerMill CAM software. With this approach, the tool does not step down immediately after each subsequent pass. Instead, extra cutting moves are added, working from the bottom of each step upwards. As a result, the initial cutter can take a much deeper axial depth of cut and remove a greater amount of material, minimizing the amount of subsequent rest roughing that’s required. Depending on the geometry of the part, the overall machining time can be reduced by as much as 60 percent, the company says. Vortex will be included within the soon-to-be-released PowerMill 2013 as well as many of the company’s other CAD/CAM offerings.
On its own, this certainly seems to be a viable, high speed roughing strategy. However, as with other CAM-generated tool paths, it’s generic. That is to say, it can be used to drive pretty much any suitable CNC machine once the appropriate postprocessor is written. There is a point, though, at which the operational limits of a machine and its control come into play. For instance, a machine simply might not have the ability to maintain the programmed feed rate that would otherwise result in optimal performance. In addition, controls differ in terms of their processing speed, high speed machining parameters and method for handling arc/line transitions among other characteristics. This spurred Delcam to look more closely at how the differences between individual machines, even machines that are very similar, affect the overall speed and effectiveness of a CAM-generated tool path.
The result of these efforts is MachineDNA, a technology the company developed more or less concurrently with Vortex. (Patents are pending for both offerings.) Directly integrated into a CAM system such as PowerMill, MachineDNA enables the CAM system to gather data from a specific Carbide Inserts machine to establish a performance baseline, and use that information to create an individualized tool path shaped by the machine’s condition and capabilities. By learning and applying a machine’s own traits, different, yet effective tool paths can result even though the same overall strategy (i.e. constant engagement angle) is applied.
Individualized CAM
Simply put, MachineDNA aims to determine what type of tool path a machine “enjoys” so the CAM system can generate such a path. Through a series of simple axis motion tests in which no actual cutting is performed, a machine defines its own capabilities. These tests need not be performed every time a new tool path is created—only when configuring a new machine or after a machine has been serviced or upgraded.
To gun drilling inserts run a test, users enter basic information such as model of machine, type of control and maximum feed rate into a simple interface within the CAM system. MachineDNA automatically generates the G code that drives the machine through the exercises. During testing, data is continuously fed back and stored within a machine-specific file that the CAM software will access each time it creates a new tool path for that particular machine.
Testing reveals a handful of key performance characteristics. These include the optimal trochoid size for a given feed rate, the machine’s preferred point distribution along curves and the most effective manner for moving through arc/line transitions. These attributes would be difficult if not impossible for even an experienced programmer to accurately identify for a specific machine.
In one exercise, the machine is directed to make a series of circular movements to determine the minimal trochoid radius at which the machine can maintain the programmed feed rate. For a trochoid radius that’s smaller than optimal, the machine typically won’t be able to maintain the programmed feed rate. Conversely, the machine might be able to maintain the programmed feed rate using a larger trochoid radius, but a bigger radius equates to a longer tool path and longer cycle time.
Testing also determines the optimal point distribution to match a machine’s control capabilities. Envision a simple oval with two lines and two arcs. The CAM system might output this arrangement as two lines and two arcs; leave the lines as they are, but linearize the two arcs for a smooth, even point distribution; or redistribute points at appropriate intervals around the entire oval shape. Based on testing performed on a range of controls, MachineDNA takes into consideration the characteristics of the control as it determines the most appropriate point distribution along the tool path. It also accounts for the control’s processing speed so as not to feed a slower control too many points, which could potentially cause stuttering due to data starvation.
Finally, when a tool goes from a straight line into an arc, some controls will dwell the tool slightly at the point of the transition. These dwells must be eliminated to maintain the programmed feed rate throughout the entire tool path. In understanding the idiosyncrasies of various controls, MachineDNA provides the data that enables the CAM system to generate an optimized tool path that accounts for such control peculiarities.
Future Applications
Initially, MachineDNA will be available for use only with the Vortex roughing strategy. This will be available to customers with the release of PowerMill 2013 first, then in Delcam’s other CAM systems. However, the company plans to apply its machine diagnostics technology in other ways. It may be used to generate more effective five-axis tool paths, because the interaction between linear and rotary axes is complicated, and the machine’s performance can be affected by a greater number of variables. In addition, MachineDNA data may prove helpful in increasing the accuracy of machining time estimation.
The company says the baseline testing that MachineDNA performs is not designed to be a tool for machine benchmarking or direct comparison. In fact, the data gathered from machine tests doesn’t lend itself to any such assessment. Insetad, it simply enables a machine to achieve a higher level of its potential performance by using tool paths engineered to work in concert with a machine’s capabilities.
Sidebar: Minimizing Trochoids
Trochoidal movements are sometimes introduced to maintain a consistent engagement angle throughout the entire tool path. Vortex, however, aims to minimize the amount of rolling, trochoidal moves because the tool doesn’t cut anything for approximately half of each circle of motion. Instead, it broadly follows the shape of the part and only periodically introduces trochoidal motion to clean up the shape and maintain the optimal engagement angle. This can be seen in the tool path shown in the bottom image, in which the patterns of corner approaches are not regular. Trochoidal motion is applied only when absolutely necessary to maintain a controlled engagement angle. This differs from a conventional approach in which the tool starts in the center and spirals out until it reaches the edges of the triangle before using large trochoidal movements to work into the corners.
Delcam has developed a guide of parameters for various tools and workpiece materials because conventional roughing parameters aren’t appropriate for use with Vortex. This will enable users who aren’t familiar with controlled-engagement-angle tool paths to get their cutting parameters in the ballpark as they dial-in their process.

Custom Macro Enables Automated CNC Program Generation
It takes tooling to make tooling. For Knight Carbide, various fixtures, holders and carriers are needed to convey carbide machining inserts through the grinding and finishing operations required to make these tools. The cutting tool maker in Chesterfield Township, Michigan, primarily serves customers with specialized insert needs, and for every special tool design the company produces, new tooling for its own production process typically is needed to carry out the job. Waiting for this custom tooling to be delivered has historically been the largest contributor to Knight Carbide’s lead time. Now, lead times have begun to dramatically improve.
Edge prep carriers that used to be machined, but now are 3D printed, illustrate the reason for the change. One of these custom carriers could hold anywhere from eight to 30 carbide inserts for an abrasive edge prep operation, depending on the insert’s design and dimensions. Traditionally, a machine shop made these carriers, and Knight Carbide would wait 2 to 3 weeks to receive them. But the cutting tool maker wondered: Did these carriers really have to be made from steel? Or even metal? Through experimentation, the company discovered that a very durable plastic could also do the job. It learned this when it began to use a Mojo desktop 3D printer from Stratasys to produce the carriers in tough ABS plastic. In place of the multi-week lead time typical of the carriers, generating a carrier directly from a CAD model through 3D printing in this way requires a build time of only about 6 hours.
Moreover, the 3D CNC Inserts printed carrier is often better than the steel one. When the parts were machined, developing complex carrier designs would have been impractical. Creating tooling to hold the inserts at precise orientations during the edge prep would have required five-axis machining and/or additional setups in order to machine the needed angles into the carrier. But 3D printing is unaffected by complexity—it simply prints a tangible model of whatever CAD geometry is provided. Thus, Knight Carbide has been able to fine-tune its edge prep operation lately by using carriers that hold the inserts at precise compound angles. As a result, not only has the lead time of the edge prep operation improved, but so has its capability.
The Mojo printer employs fused deposition modeling (FDM) to generate plastic parts that
are roughly equivalent to tube process inserts what might be made through injection molding. Solid plastic forms produced this way are easily durable enough for use as tooling—at least in many cases.
Knight Carbide Vice President Chris Kyle says there have been failures. An FDM linkage used in a workholding system for securing inserts rigidly proved too flexible to maintain the required clamp. Also, the hope of replacing customized steel fixtures in a twin-spindle surface grinding machine was not realized, because the heat of grinding in this machine was sufficient to melt the plastic. Mr. Kyle says the company is still exploring in this way, learning by trial and error to discover all that the 3D printer might do.
One other successful application that illustrates the potential for efficiency gain involves holders used for peripheral grinders, he says. In this application, too, an insert needs to be held at a particular angle as a particular feature is precision ground. Knight Carbide technicians used to create these custom-angled holders by hand, assembling the holders out of hardware available in the shop. Building one of these tools might take a skilled employee the better part of a day. But now, that holder geometry—precisely achieving whatever insert angle is needed—can be generated in the 3D printer while the skilled employee tends to other work.
3D printing is still new enough for the company that most of the production tooling is still the traditional steel. Going forward, Mr. Kyle sees the company systemizing and learning to rely more on the productivity gains the printer can deliver. In a way, the old, longer-lead-time process was easier to manage. Since insert production could not proceed until tooling arrived from the outside supplier, there was no choice but to wait. But now, the opportunity—as well as the challenge—is to leverage the new capability in order to respond more quickly. This will involve incorporating 3D printing of production tooling into the standard workflow.
“Six hours to build each edge prep carrier is fast compared to what we were used to, but it’s still a significant amount of time,” Mr. Kyle says. And typically there are multiple carriers for any given job. (The edge prep machine accommodates up to six of them.) Thus, the production process has to allow time for all of this 3D printing. Fortunately, though, edge prep comes late enough in the insert manufacturing process that—if the workflow is designed well—there ought to be plenty of time to let carriers be printed while carrying out other manufacturing steps.
In the meantime, Knight Carbide continues to find other uses for the printer. It has proven to be valuable for communicating with customers, Mr. Kyle says, because the company can now print a physical model of any new carbide insert design to let the customer confirm that the form of the tool is correct. Thus, while most 3D printing users start with prototyping and move later to functional parts, Knight Carbide has gone in the opposite direction. After investing in 3D printing to make functional tooling, the company now sees prototyping as an added source of value.
