High-frequency induction heating chemical dressing device for brazing diamond milling and grinding tools

Abstract

The invention provides a high-frequency induction heating chemical dressing device for a brazed diamond abrasive router. According to the high-frequency induction heating chemical dressing device, real-time high-temperature graphitization chemical dressing of the brazed diamond abrasive router on a machine can be realized, the air in a dressing area can be effectively isolated under pure nitrogenprotection or the isolation atmosphere, the oxidation loss of an ultrahigh-strength steel high-temperature dressing base body in a high-temperature environment is greatly reduced, and the use period and the use stability of the ultrahigh-strength steel high-temperature dressing base body are improved; a nitrogen protection connector or an isolation atmosphere connector and a high-frequency induction heating coil are all connected with a control valve of a numerical control machine tool, and therefore all PLC data can be read by a PLC while the pressure, the flow as well as the start and stop can be controlled, the numerical control machining program and the start-stop control of the dressing device can be built in, and the numerical control is completely realized; and a built-in type thermocouple is used for measuring heat deformation before the use of the ultrahigh-strength steel high-temperature dressing base body and the use process of the ultrahigh-strength steel high-temperature dressing base body and for controlling the environment temperature in the dressing process.

Description

technical field [0001] The invention relates to a high-frequency induction heating chemical trimming device for brazing diamond milling and grinding tools. Background technique [0002] Brazed Diamond Abrasive Router (Brazed Diamond Abrasive Router) is a typical application of superabrasive "grinding instead of milling" process in the field of mechanical processing. Brazed diamond milling tools have been widely used in carbon fiber reinforced composites, titanium-based composites, ceramics and ceramic-based composites due to their excellent interphase bonding strength, large abrasive grain exposure height and chip space. , glass and other difficult-to-process materials processing production process. [0003] Due to the different particle sizes of the abrasive grains, the shape difference of the abrasive grains, and the random distribution of the abrasive grains on the surface of the tool substrate, the diamond grains in the circumferential direction of the tool are at the b...

Problems solved by technology

However, this method is very easy to cause the abrasive grains to be broken as a whole at the joint, and instead causes the contour of the abrasive grains to deteriorate. At the same time, there are disadvantages such as low dressing efficiency and high positioning accuracy of the equipment.

These defects also further limit the application of diamond brazing tools in the field of actual processing, especially in the field of precision machining.
