How is the machining tool manufactured?

In general, the material of the milling cutter is divided into:

 

1. HSS (High Speed Steel) is often referred to as high speed steel. Features: not very high temperature resistance, low hardness, low price and good toughness. Generally used in drills, milling cutters, taps, reamers and some forming tools. Generally, where the general precision requirements are not too high, the processing and manufacturing of the milling cutter generally selects the rolled bar material, and after a certain heat treatment process (adjusting the hardness, eliminating the stress), it is ground on the tool grinding machine. For high-precision and demanding HSS tools (usually accompanied by a 5-10um wear-resistant special coating, usually after physical or chemical vapor deposition after final grinding) is generally achieved with a CNC tool grinder, such as a spiral groove Taps.

2. Cemented carbide

①. Indexable carbide inserts (some special coatings containing 1 or several layers for different purposes). The inserts are usually pressed by powder metallurgy and high temperature and high pressure. As a general turning insert, the coating can be added after pressing. Use (In the same batch of pressed blades, the blades have good dimensional consistency (within 5um). Milling cutters generally have high runout requirements, and the number of blades per tool is from 1 to 100+. Therefore, the blade of the milling cutter must be finely ground to achieve sharpness (there is also such a requirement for the finishing blade of the lathe) and the dimensional consistency. The cutter body material of the milling cutter is generally tempered by 42CrMo4+, and the cutterhead passes through the high. Precision CNC milling to complete the machining. Shank and rivet (take DIN69871-69872 shank as an example), material selection 42CrMo4 + roughing + QT + semi-finishing + partial surface quenching + blackening + fine grinding + dynamic balance calibration. auto part

②. Solid carbide milling cutter + drill + tap + reamer. Carbide rods are ground directly on the CNC tool grinding to the final dimensions. For more different applications, the tool can be attached to different applications (increased wear resistance, more impact resistance, etc.). Advantages High precision, wear resistance Wide range of processing materials Machinable high hardness materials (extremely HRC60-65) This tool is limited by the diameter of the bar, and generally does not exceed D40.

③. Welded carbide tool with milling cutter + large reamer + larger diameter drill bit (the drill body is often high speed steel) + large hobbing cutter carbide blade is welded to the body by copper rivet welding, The final size is then achieved by grinding. Through welding, carbide milling cutters can reach larger sizes and diameters, and the cost can be reduced. plastic part

 

3. Ceramics after high temperature and high pressure pressing, grinding + coating

 

4. CBN After high temperature and high pressure pressing Grinding + coating
