The general steps for tap grinding are as follows

The general steps for tap grinding are as follows: 1. Inspection and evaluation: Check the wear and damage of the tap to determine if it is suitable for grinding. Taps that are severely damaged or excessively worn may need to be scrapped. 2. Cleaning: Remove oil stains, chips, and other impurities from the surface of the tap for subsequent grinding operations. 3. Clamping: Fix the tap on the grinder or specialized grinding equipment to ensure it is firm and not loose. 4. Grinding the front and back corners: According to the geometric shape of the tap, grind its front and back corners to restore the sharpness of its cutting edge. 5. Trimming the spiral groove: If the spiral groove of the tap is also worn, it can be trimmed to ensure smooth chip removal. 6. Inspection and testing: After grinding, inspect the tap to ensure that all its parameters meet the requirements. The grinding effect can be verified through trial cutting or measurement.

The application cases of graphite milling cutters

The application cases of graphite milling cutters

Due to the advantages of fast discharge speed, light weight, good thermal stability, and high possibility of forming complex shapes, more and more mold customers are using graphite as the preferred electrode material. At the same time, due to the characteristics of graphite material and the different cutting principles from metals, the processing of graphite not only puts higher requirements on cutting tools, but also has significant differences in processing strategies from typical copper electrodes. How to efficiently process graphite electrodes poses great challenges for customers themselves. Nanjing Jianchuanshi has a wealth of processing experience in the field of graphite processing. Jianshi is willing to help customers improve the processing efficiency of its graphite electrodes, and then leverage the advantages of graphite electrodes in molds and products.

Four-axis turntable tooling case

Four-axis turntable tooling case

CNC turntable is a machine tool with a rotatable table, used to clamp the workpiece and achieve rotation and indexing positioning, referred to as the turntable or the fourth axis. According to the different functions, the turntable can be divided into two categories: general turntable and precision turntable. It is an important accessory such as boring machine, drilling machine, milling machine and slotting machine. It is used to process holes, grooves and inclined planes with indexing requirements. When the worktable is rotated during processing, it can process arc surfaces and arc grooves. General turntable according to the different structure is divided into horizontal turntable, vertical and horizontal turntable and universal turntable.
