Optimization coating of cylindrical tools with fixture for increasing machine capacity

Abstract

The coating technology is integral part of industrial production. In the tooling field, coating is an essential part. For the vast majority of tooling materials today, a coating that has abrasion resistance, high hardness, high temperature stability, as well as overall wear resistance of the cutting edge is a matter of course and necessity. However, coating machines are designed for a maximum predetermined number of tools. It would be possible to increase the capacity of the coating machine by means of a jig designed specifically for the given machine with given kinematics. The topic of this article is the design of the jig for increasing the capacity of the coating PVD machine. The main part is the design and construction of the jig, where the construction of the movement system is described. Then follows the design of the material and description of the main principle operation of the product. The jig will be designed for coating cylindrical tools, the monolithic milling cutters and drills made mostly of cemented carbide. When coating such tools with the PVD method, care must be taken to avoid so-called "shadow effects". This fact must also be reflected in the design of the fixture. Increasing the capacity of the PVD of the machine will lead to an increase in the production batch and thus an increase in profit.
