Diamond blunt tool

Abstract

The invention discloses a diamond blunt tool, which comprises a cutter body, wherein the cutter body is disc-shaped, a group of tooth holders are uniformly arranged on the circumference of the cutter body, and each tooth holder is provided with a cutter tooth. The diamond blunt tool comprises multiple cutter teeth, and each cutter tooth is independent so as to be convenient for replacing each damaged cutter tooth, the cost is reduced, the cutter teeth are made of diamond, and hardness, precision and stability are further better than the cutter teeth made of high-speed steel and alloy, so that the processed pencil has stable appearance and specification and high precision, the defective index of a product is reduced, profited by the hardness of the diamond, the service life durability of the tool is greatly reduced, more than 5000000 tools can be processed regularly, the replacement period of the tool is reduced, and the production efficiency of pencil processing is improved, so that the surface smoothness of the pencil end is greatly improved, a core break rate of a cartridge is reduced by 50%, the surface oil paint of the pen is difficult to crack, meanwhile, the processing noise of the tool is remarkably reduced, and the comfortableness of a work environment is provided.

Description

technical field [0001] The invention relates to a processing workpiece of a wood product pen and a wood-plastic pen, in particular to a diamond trim cutter for edge trimming and surface finishing of a pen end. Background technique [0002] At present, there are two main methods for edge trimming and surface finishing of the ends of wood pens or wood-plastic pens, one is high-speed steel round blade finishing, and the other is hard alloy blade saw blade finishing. [0003] The high-speed steel round blade is adopted, and the blade rotates at high speed to directly cut the end face of the pen. At the same time, a high-speed rotating grinding wheel is always grinding the cutting edge of the blade to keep the cutting edge sharp. The main component of this method is the high-speed steel blade. Due to the poor wear resistance of the high-speed steel material, a high-speed rotating grinding wheel must be used to grind the cutting edge at all times to keep the cutting edge sharp. T...

AI Technical Summary

Problems solved by technology

Disadvantages: The cutting edge material has poor wear resistance, poor saw blade precision, poor concentricity, and the core of the processing pen is easy to break

The processed pen core often has chipping phenomenon, the surface of the pen end surface has obvious scratches, and the surface paint is easy to crack
