A fast and efficient shaping method for superabrasive grinding wheel

Abstract

The invention discloses a quick and efficient shaping method of a super-abrasive grinding wheel. The quick and efficient shaping method specifically comprises the steps that a trimming wheel driver is mounted on a grinding machine; a spindle of the grinding machine is arranged to be perpendicular to a spindle of the trimming wheel driver; a to-be-trimmed grinding wheel is mounted on the spindle of the grinding machine; a trimming wheel is mounted on the trimming wheel driver; axes of the to-be-trimmed grinding wheel and the trimming wheel are arranged in a crossed manner, to allow the directions of linear speeds of the to-be-trimmed grinding wheel and the trimming wheel to be mutually perpendicular; a motor of the spindle of the grinding machine and a motor of the trimming wheel driver are connected with frequency converters of the grinding machine and the trimming wheel driver respectively; and the frequency converters are connected with a PLC (Programmable Logic Controller). In addition, time domain control of rotating speeds of the to-be-trimmed grinding wheel and the trimming wheel has periodicity; periods of the to-be-trimmed grinding wheel and the trimming wheel are identical; a phase difference between the to-be-trimmed grinding wheel and the trimming wheel is 180 degrees; and when the super-abrasive grinding wheel grinds and shapes, a high speed of the to-be-trimmed grinding wheel is matched with a low speed of the trimming wheel, and a low speed of the to-be-trimmed grinding wheel is matched with a high speed of the trimming wheel. Compared with the traditional grinding method having the defect that a grinding wheel shaped by traditional grinding method has single trimmed comet tails, the shaping efficiency of the super-abrasive grinding wheel can be increased by times, the consumption of the trimming wheel is reduced, and energy conservation and environment protection are facilitated.

Description

technical field [0001] The invention belongs to the technical field of grinding wheel manufacture and application, and in particular relates to a fast and efficient shaping method for superabrasive grinding wheels. Background technique [0002] Grinding wheel dressing is one of the basic technologies of grinding process. Through dressing, the surface of the grinding wheel can obtain ideal shape and position accuracy, dimensional accuracy and grinding ability. Superabrasive (diamond and CBN) grinding wheels, due to their high wear resistance, are one of the main development directions of modern processing technology, but the dressing of superabrasive grinding wheels is extremely difficult, which seriously restricts the application of superabrasive grinding wheels. The high-efficiency and precise green dressing of superabrasive grinding wheels has become a key topic of research by scholars at home and abroad. Usually, the dressing of superabrasive grinding wheels includes two...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the current superabrasive wheel grinding method has low shaping efficiency and fast dressing wheel consumption. The dressing efficiency of the hard abrasive grinding wheel, and the consumption of the dressing wheel is greatly reduced, which is conducive to energy saving and environmental protection
