Multi-wire grinding device

Abstract

The invention discloses a multi-wire grinding device which is characterized in that an inverted triangle bracket fixed to the front side surface of a bed, a grinding mechanism for grinding a to-be-ground workpiece, a supporting unit located below the grinding mechanism and used for supporting and moving the to-be-ground workpiece, and a cooling mechanism fixed to the front side surface of the bed are arranged on the front side of the bed; the grinding mechanism is provided with a pay-off wheel, a take-up wheel, a left guide wheel, a right guide wheel and a contact wheel; the pay-off wheel and the take-up wheel are connected with the front side surface of the bed, are located on the two sides of the bottom corners of the inverted triangle bracket respectively and are used for winding a diamond wire; the left guide wheel, the right guide wheel and the contact wheel are arranged on the inverted triangle bracket and used for arranging the diamond wire between the pay-off wheel and the take-up wheel into a diamond wire row through supporting; the supporting unit is provided with a vertical moving mechanism and a horizontal moving mechanism; the vertical moving mechanism is arranged on a coolant recovery tank of the cooling mechanism and used for driving the to-be-ground workpiece to move vertically; and the horizontal moving mechanism is arranged on the vertical moving mechanism and used for driving the to-be-ground workpiece to move horizontally. A situation that the precision is affected due to blocking of cutting chips is prevented effectively, the cutting heat is reduced, and the probability of heat injury to the surface of the workpiece is reduced.

Description

technical field [0001] The invention relates to a grinding processing device. In particular, it relates to a multi-line grinding device for superhard material grinding. Background technique [0002] Multi-wire cutting technology began to develop in the 1990s. This cutting method is to wind a slender steel wire on the wire arranging wheel, and the two ends of the steel wire are respectively tensioned by the wire-releasing mechanism and the wire-receiving mechanism. A number of tension control wheels are installed between the take-up and pay-off mechanism and the wire arranging wheel to control the rigidity of the steel wire. The wire arranging wheel rotates forward and reverse rhythmically at high speed to realize the reciprocating motion of the steel wire, and at the same time, it brings the mortar into the processing area for grinding and cutting. Mortar is a fluid with a certain viscosity that is made by mixing cutting fluid (such as polyethylene glycol) and silicon car...

Problems solved by technology

However, this processing method has low efficiency and high cost, the grinding wheel is easy to clog, and the high processing temperature is easy to burn the surface of the workpiece, which restricts the application of non-metallic superhard materials in industry
