The vertical mill adopts dynamic powder selecting device, which comes with high powder-selecting efficiency and convenient adjustment of fineness.
China ZK Corp has provided various kinds of large and medium size complete sets of cement production equipments for more than 300 cement customers in domestic market. And engineering for equipment and technology, manufacturing, installation and commissioning as well as the supply of the spare parts and the training service can be offered by China ZK for customers.
The material is grinded between rotor and ring as the rotor is rotating. The ground powder will be blown into the classifier; the fine powder will be collected by the collector while the coarse powder will be regrinded to the required size.

High Efficiency Milling (HEM) is a strategy that is rapidly gaining popularity in the metalworking industry. Most CAM packages now offer modules to generate HEM toolpaths, each with their own proprietary name. In these packages, HEM can also be known as Dynamic Milling or High Efficiency Machining, among others. HEM can result in profound shop efficiency, extended tool life, greater performance, and cost savings. High performance end mills designed to achieve higher speeds and feeds will help machinists to reap the full benefits of this popular machining method.
HEM is a milling technique for roughing that utilizes a lower Radial Depth of Cut (RDOC) and a higher Axial Depth of Cut (ADOC). This spreads wear evenly across the cutting edge, dissipates heat, and reduces the chance of tool failure.
This strategy differs from traditional or conventional milling, which typically calls for a higher RDOC and lower ADOC. Traditional milling causes heat concentrations in one small portion of the cutting tool, expediting the tool wear process. Further, while Traditional Milling call for more axial passes, HEM toolpaths use more passes radially.
Machining technology has been advancing with the development of faster, more powerful machines. In order to keep up, many CAM applications have developed built-in features for HEM toolpaths, including Trochoidal Milling, a method of machining used to create a slot wider than the cutting tools cutting diameter.
HEM is largely based on the theory surrounding Radial Chip Thinning, or the phenomenon that occurs with varying RDOC, and relates to the chip thickness and feed per tooth. HEM adjusts parameters to maintain a constant load on the tool through the entire roughing operation, resulting in more aggressive material removal rates (MRR). In this way, HEM differs from other high performance toolpaths, which involve different methods for achieving significant MRR.
Virtually any CNC machine can perform HEM the key is a fast CNC controller. When converting from a regular program to HEM, about 20 lines of HEM code will be written for every line of regular code. A fast processor is needed to look ahead for the code, and keep up with the operation. In addition, advanced CAM software that intelligently manages tool load by adjusting the IPT and RDOC is also needed.
The following example shows the result a machinist had when using a Helical Solutions HEV-5 tool to perform an HEM operation in 17-4PH stainless steel. While performing HEM, this diameter, 5-flute end mill engaged the part just 12% radially, but 100% axially. This machinist was able to reduce tool wearand was able to complete 40 parts with a single tool, versus only 15 with a traditional roughing toolpath.
The effect of HEM on a roughing application can also be seen in the case study below. While machining 6061 aluminum with Helicals H45AL-C-3, a 1/2, 3-flute rougher, this machinist was able to finish a part in 3 minutes, versus 11 minutes with a traditional roughing toolpath. One tool was able to make 900 parts with HEM, a boost of more than 150% over the traditional method.
Generally speaking, HEM is a matter of running the tool not the tool itself. Virtually every tool can perform HEM, but using tooling built to withstand the rigors of HEM will result in greater success. While you can run a marathon in any type of shoes, youd likely get the best results and performance from running shoes.
HEM is often regarded as a machining method for larger diameter tooling because of the aggressive MRR of the operation and the fragility of tooling under 1/8 in size. However, miniature tooling can be used to achieve HEM, too.
HEM is a machining operation which continues to grow in popularity in shops worldwide. A milling technique for roughing that utilizes a lower RDOC and higher ADOC than traditional milling, HEM distributes wear evenly across the cutting edge of a tool, reducing heat concentrations and slowing the rate of tool wear. This is especially true in tooling best suited to promote the benefits of HEM.
Thanks for your comment and sorry for the confusion! Youre right it should say Total Cost per Part. The shop burden rate is factored into the total cost so the total cost relates to the time to machine the part as well as the price of the tool. Well get it changed shortly.
It makes sense that you would want to keep a constant load on the equipment youre using when milling mechanically. I would assume that this would help preserve what youre using as to ensure that it lasts longer than it normally would. That way you can save a bit of money by being able to produce more without having to worry about repairs.Get in Touch with Mechanic
