1 tool requirements

CNC punch press can be used for rough turning. In order to make the rough turn to the full depth, to the knife, roughing tool with high strength, durability, precision car is to ensure precision machining and tooling precision, durability, a good method. In order to reduce tool change time and convenient tools, use the knife holder as much as possible. The use of machine tools can be set automatically for the tool. If the traditional lathe by machine tool clamping is only an active, then the use of machine tools in the CNC lathe is a requirement. Cutter body of the knife body requires high precision, should be a reasonable choice clamping blade. The machine adopts CNC lathe, generally without gasket adjustment, high precision, should be guaranteed in the manufacturing. For the tool diameter of the aspect ratio, it is preferable to have an anti-vibration structure. The inner diameter of the coolant is preferably introduced from the body of the cutter, and then from the tip near the jet. On blades, in most cases, cemented carbide inserts should be coated. Coatings are better than (> 100 /) at high cutting speeds. Ordinary lathe cutting speed is generally not to, so the Zhengzhou punch with a hard alloy blade can not be coated. Blade coating adds less than double the cost, while the use of CNC lathe durability can be increased more than 2 times. The coating blade can increase the cutting speed, thereby improving the processing efficiency. Under normal circumstances, titanium carbide, titanium nitride and alumina coating materials, in the same blade can also be applied to different layers of material, composite coating. CNC lathes on the chip breaker chip breaker higher requirements. The reason is simple: CNC lathes in a closed environment with a high degree of automatic cutting, so in the turning process is difficult for a large number of chips for manual processing. If the broken chip is not good, it will be wrapped in the head, can squeeze the bad blade, will cut the surface strain. Ordinary lathe and carbide blade is generally two-dimensional chip breaking in the chip is usually used in CNC turning inserts. Punch three-size chip breaker in many forms, usually in the blade factory to form a number of standards. The common feature is good chip breaking performance and wide chip breaking range. For concrete material parts, the cutting parameters set, we should pay attention to select the blade slot. The selection process can be used to do some theoretical discussion, but more important is to experiment. In some cases, the cutting parameters can be modified according to the slot of the existing blade. It is no doubt that the blade has a high degree of durability.

CNC lathe also requires good consistency of the blade in order to facilitate the use of tool life management functions. When using tool life management, its setting principles and durability are based on the leaf blade’s minimum durability. In this case, the consistency of the blades is more important than the average life expectancy. As for the accuracy, the same accuracy of the blade is good.

2 knife seat (folder) requirements

Tool (edge) tools rarely installed directly in the CNC lathe tool holder, they generally use the knife seat (also known as the knife clip) transition. The shape of these three factors and the shape of the tool, punch knife block structure mainly depends on the knife body spindle configuration. The type of knife seat is the factory thing, the degree of standardization is low. The machine tool turret configuration is a total of only a few spindles; only the tool shape (mainly refers to the part of the connection with the knife seat) type too much. Users in the selection, should minimize the type, type, to facilitate management.
