Features And Uses Of PCD&PCBN Tool Grinding Machine


Most designs of the 2-axis PCD&PCBN tool grinding machine have the following two characteristics: First, while sharpening the PCBN and PCD tools, taking into account the natural diamond tools; Second, sharpening and welding super-hard turning tools and boring tools, but also taking into account the disc and shaft tools.

Features of PCD&PCBN tool grinding machine

At present, with the rapid development of the market and technology, PCD & PCBN tool grinding machine has been widely used, so the market for PCD & PCBN tool grinding machine. Grinding equipment places high demands on grinding efficiency, mainly as follows. 1. The main part of the auxiliary time requires a significant reduction in the working time of the knife. The rotation of the table to form the arc of the blade, the adjustment of the center of the tool arc to coincide with the rotation axis of the table is a prerequisite for grinding. And the "tool setting action" runs through the entire process of tool grinding and is repeated continuously. This is the fundamental reason why traditional machine tools can't get rid of manual operations. 2. The operation is convenient and reliable, try not to rely on the manual skills of the operator. In order to grind natural diamond tools, conventional machine tools introduce the processes of "flexible feed" and "constant pressure grinding". These two processes have a "knife" protection effect on a very brittle natural diamond knife. Conventional equipment uses a cylinder feed to achieve this effect, which greatly sacrifices the grinding efficiency of the PCD & PCBN tool grinding machine. 3. Increase the specific gravity of the indexable insert grinding, which requires the equipment to have a strong specialty, simple and rigid structure. With the deepening of the division of labor, more than 80% of customers use the same equipment for the same type of tool, namely PCNB, PCD or alloy indexable inserts and welding tools. However, for a single requirement, the machine structure can be simplified and the rigidity of the device can be greatly enhanced. This not only reduces equipment costs but also lays the foundation for solid and efficient production.

Uses of PCD&PCBN tool grinding machine

1. Can achieve large margin rough processing The integral can realize large-volume roughing. At present, the integral CBN tool can reach a depth of 8mm, can eat the entire blade, and the production efficiency is doubled. 2. High-speed cutting Thanks to the good performance of the PCBN tool itself, high-speed cutting can be achieved completely. And it can perfectly combine with CNC machine tools, which makes high-efficiency cutting of workpieces greatly improve production efficiency. 3. Dry processing Due to the high thermal redness of the PCBN tool, if the coolant is added, the blade will crack due to the sudden drop in temperature. Therefore, the CBN tool generally uses dry cutting when machining the workpiece, especially in the case of intermittent cutting. Turning is not only environmentally friendly but also saves a certain cost. 4. Suitable for processing high hardness materials The hardness of the CBN material is after the diamond and the PCBN is a very hard tool material that is second only to diamond. Therefore, the diamond tool is collectively referred to as a superhard tool. Normally, the PCBN hardness is better than 48HRC (the CBN wears very quickly when processing soft materials). The temperature is as high as 2000 ° C and there is excellent red hardness. Proper custom PCBN tools can withstand the high heat roughing of the cutting load, the interrupted cutting, and the heat and wear required for fine machining. In general, the 2-axis PCD&PCBN tool grinding machine is currently the most ideal tool material for processing ferrous metals. In the future, with the application of high-hardness and difficult-to-machine materials, the market share of PCBN tools will gradually increase. Will become the mainstay of the hard materials processing industry.
