Embodiment 1

[0029]The present invention provides a grinding device for PCD / CBN tools. The grinding method adopted by the grinding device is the grinding method of the knife. For example, the main task of fine grinding of diamond tools is to accurately and stably control the grinding final dimensional accuracy. However, during the grinding process of diamond tools, changes in the position of the grinding wheel caused by changes in the inclination angle of the grinding wheel, wear on the end face of the grinding wheel, and changes in the thickness of the blade will all cause changes in the grinding point of the edge tip, which will eventually lead to machining errors. These factors have nothing to do with the motion accuracy of the machine tool, but are related to when to start grinding (that is, the tool setting point) and to what extent the grinding ends. The "knife grinding method" is to use audio sensors to accurately monitor the position of the grinding point to achieve precise control...

Embodiment 2

[0031] Application in grinding adaptive control: The main task of coarse grinding diamond is: to improve the grinding efficiency, that is, to set the safety distance as little as possible, and to reduce the time of "grinding" air; within the tolerance range of machine tool rigidity , remove the grinding allowance as soon as possible; find that the grinding allowance has been removed as early as possible (the sign is that the grinding resistance is reduced to the minimum); the friction between the grinding wheel and the diamond tool produces severe sound waves that propagate on the process equipment, and the monitoring of sound waves can be accurate It can accurately reflect the grinding status, such as whether the tool is in contact with the grinding wheel, whether the pressure between the tool and the grinding wheel (that is, the grinding resistance) is eliminated, etc. If the control system can collect and analyze this information in real time, so that the machine tool contro...

Abstract

The invention relates to a grinding device for a PCD / CBN cutter. The grinding device comprises a cutter frame, a grinding wheel, a grinding wheel fixing device and an audio sensor. The grinding wheel is fixed at the left end of the grinding wheel fixing device through a flange plate, the ground cutter is arranged on the cutter frame, and the cutter frame is arranged on the left of the grinding wheel fixing device and corresponds to the grinding wheel. The grinding wheel fixing device comprises a main shaft, a synchronous permanent magnet rotor, a synchronous stator winding, a main shaft front end cover and a main shaft rear end cover, the main shaft is sleeved with the synchronous permanent magnet rotor, the synchronous permanent magnet rotor is sleeved with the synchronous stator winding, and the main shaft front end cover is arranged at the left end of the main shaft. The grinding device further comprises a sensor signal amplifier, and the audio sensor is connected with an external numerical control system through the sensor signal amplifier. The grinding device for the PCD / CBN cutter has the advantages of being capable of guaranteeing grinding precision for a long time, achieving high grinding efficiency and having safety measures such as collision prevention.

Description

technical field [0001] The invention relates to a grinding device for PCD / CBN cutting tools. Background technique [0002] At present, PCD / CBN tools are very hard due to the superhard material tool material, which can greatly improve the life of the tool from the application level, expand the material range of the machined parts, and greatly improve the quality of the machined surface. Advanced cutting tools for the development direction of modern machining industry. However, in the process of grinding PCD / CBN tools, the characteristic of high hardness also creates many uncertain factors for the process factors of tool grinding (such as the size of the grinding wheel and the state of the abrasive grains, etc.), which affects the grinding process. great difficulty. [0003] The shape and surface of the cutting edge of existing PCD / CBN tools are mostly realized by grinding, and its working mechanism is between grinding and grinding. The quality of the cutting edge of the too...
