Problems solved by technology

In the superhard sharpening machines currently on the market, the feed mechanism is heavy due to the weight of the slide table, and the friction coefficient of the slide table is relatively large, so the rebound force is relatively large when the tool is sharpened, so it is difficult to grind brittle materials such as single crystal diamond. For large knives, the cutting edge is easy to crack; some scholars have proposed to use magnetic or air-suspended sliding table mechanism, but its cost is high, so it is rarely used in the market. In addition, the superhard tool sharpening equipment currently on the market has a complex structure and high cost

Abstract

The invention discloses an arc blade milling machine for a swing arm tool, which mainly comprises a machine body, a control system, a milling head assembly, a small cross-shaped slide seat, a revolving working platform and a tool rest. The arc blade milling machine is characterized in that a feed moving mechanism adopts a swing arm mechanism; the revolving working platform is installed on a swing arm and is provided with the small cross-shaped slide seat, and the small cross-shaped slide seat is provided with the tool rest; the machine body is provided with a reciprocation sliding table parallel to a milling wheel surface direction; and the milling head assembly or the swing arm mechanism is installed on the reciprocation sliding table. The arc blade milling machine for the swing arm tool has the advantages of good feed flexibility, simple and economic structure, strong principal axis rigidity and good blade milling quality, and is widely suitable for milling precise machining tools and super hard tools.

Description

technical field [0001] The invention relates to a cutting tool sharpening machine, in particular to an arc sharpening machine for superhard cutting tools. technical background [0002] With the popularization and application of cutting tools made of superhard materials such as diamond, cubic boron nitride, and ceramics, especially the new trend of turning grinding instead of grinding, people have become more and more demanding on the sharpening of turning tools. Traditional manual grinding of turning tools It has been difficult to meet the requirements, especially in terms of finish, which has prompted people to pay more and more attention to machine grinding tools. In the superhard sharpening machines currently on the market, the feed mechanism is heavy due to the weight of the slide table, and the friction coefficient of the slide table is relatively large, so the rebound force is relatively large when the tool is sharpened, so it is difficult to grind brittle materials su...
