Abrasive features

Abrasives are tools for grinding, grinding and polishing. Most of the abrasives are artificial abrasives made of abrasives and binders, and are also natural abrasives that are directly processed from natural mineral rock. In addition to being widely used in machinery manufacturing and other metal processing industries, abrasive tools are also used in grain processing, paper industry, and non-metallic materials such as ceramics, glass, stone, plastic, rubber, and wood. In the course of using the abrasive tool, when the abrasive particles are blunt, the abrasive particles partially or completely fall off from the abrasive tool due to the part of the abrasive particles being broken or the bonding agent is broken, and the abrasive material on the working surface of the abrasive tool is constantly undergoing new cutting. Edge, or constantly exposed new sharp abrasive particles, so that grinding tools can maintain cutting performance in a certain period of time. This self-sharpening of the grinding tool is a prominent feature of the grinding tool compared with general tools.

T-slot milling cutter

T-slot milling cutters can be divided into taper shank T-slot milling cutters and straight shank T-slot milling cutters.

Uses: Used to process T-slots on various mechanical mesas or other structures.

Features and Accuracy: It is a special tool for processing T-slots. Once the straight slot is milled out, it can be used to mill T-slots with the required accuracy. The end angle of the cutter has a suitable cutting angle, and the teeth are designed according to helical and offset teeth. , Smooth cutting, small cutting force.

Specification Description: T-slot milling cutter generally describes its model from the following aspects: disk and tooth diameter (outer diameter), disk thickness (blade length), number of teeth (number of blades), handle diameter ( Shank diameter), full length.

Twist drill hole accuracy is low? It turned out that these four points caused

1, correct sharpening cutting angle and improve surface roughness:
The bit is similar to the reamer. If there are two main cutting edges and secondary cutting edges, the secondary cutting edge is spiral, with lands and chamfers, which can increase the smoothness of cutting. As long as the cutting angle and surface roughness of the drill are improved and improved with reference to the requirements of the cutting edge. Basically there is a condition similar to a hinged blade.
2, determine the reasonable amount of cutting In the amount of cutting, the impact on the hole accuracy is the depth of cut and the amount of feed, the greater impact on the service life of the bit is the cutting depth and cutting speed. For this purpose, the depth of cut, cutting speed, and feed amount should be controlled separately. Avoid large cuts, reduce heat, avoid shocks and vibrations, eliminate cold work hardening, improve processing quality, and extend bit life. Pre-drilling should prevent the production of more chilled layers, which can increase the drilling load and wear out the fine hole drill.
3. Due to the precision machining of the drilling hole, its accuracy and surface roughness are high, and the cutting load is small. Therefore, the lubrication-based cooling lubricant should be selected.
4, because the drill will wear after multiple uses, and affect the aperture accuracy. The two cutting edges of the drill should be as symmetrical as possible. As a complex tool, the drill bit requires a large degree of durability, and imposes a certain limit on the wear amount of the corner as a blunt standard.
