Composite material for tool holder and tool holder

Abstract

The invention belongs to the technical field of cutter bar materials and particularly discloses a composite material for a cutter bar and the cutter bar. The composite material is prepared from components in parts by weight as follows: 10-20 parts of polyimide resin powder, 80-90 parts of tungsten carbide and 5-10 parts of a resin liquid. The cutter bar is simple in structure, convenient to produce and low in cost.

Description

technical field [0001] The invention belongs to the technical field of cutter rod materials, and in particular relates to a composite material for cutter rods and a cutter rod. Background technique [0002] At present, in the field of mechanical manufacturing finishing, the precision is required to reach the micron level. In order to improve production efficiency and reduce labor and production costs, the method of replacing grinding with turning is usually used, so the stability of turning is highly required. Due to the vibration of the tool bar, the machining accuracy cannot be guaranteed, and the machined surface is corrugated, which cannot meet the surface roughness requirements of the product. It will also generate a lot of noise, which will easily cause wear on the blade and tool bar, and even cause damage to the blade and knife. Rod cracked during use. In the prior art, when the processing structure of the product parts is allowed, the method of supporting the tool b...

Problems solved by technology

Due to the vibration of the tool bar, the machining accuracy cannot be guaranteed, and the machined surface is corrugated, which cannot meet the surface roughness requirements of the product. It will also generate a lot of noise, which will easily cause wear on the blade and tool bar, and even cause damage to the blade and knife. rod cracked during use

In the prior art, when the processing structure of the product parts is allowed, the method of supporting the tool bar at both ends is used to reduce the vibration, but this method is not suitable for processing deep holes and other situations that require a long tool bar, and there are foreign imports. The cutter bar is made of anti-vibration material, but the material composition is complicated, the processing is difficult and the price is expensive, which greatly increases the manufacturing cost. Some domestic manufacturers use methods such as changing the design structure and simple drilling and milling to reduce vibration. These methods can be effective Reduce vibration but easily reduce the rigidity of the tool holder
