Description

Combined cutter for grinding

Technical Field

The invention relates to a combined cutter for processing, in particular to a combined cutter which can uniformly process the surface along with the ovality of the inner surfaces of a rolled bar and a rolled tube blank and the curvature of the inner surfaces in the length direction.

Background

And in the grinding process, the mechanical processing belongs to the processing modes of finish processing (including rough processing, finish processing, heat treatment and the like), the processing amount is small, and the precision is high. The carbon tool steel and the carburized and quenched steel parts subjected to heat treatment quenching are widely applied to the mechanical manufacturing industry, a large number of regularly arranged cracks, namely grinding cracks, often appear on the surface basically vertical to the grinding direction during grinding, and the grinding cracks not only affect the appearance of the parts, but also directly affect the quality of the parts more importantly. Cutting processing of processing the surface of a workpiece by using a grinding tool such as a grinding wheel rotating at a high speed. Grinding is used for machining inner and outer cylindrical surfaces, conical surfaces and planes of various workpieces, and special and complex forming surfaces such as threads, gears and splines.

At present, the surface processing treatment of the bar and the tube blank adopts a method of external grinding and internal grinding, and an oxide layer on the surface of a workpiece is removed by a grinding method to form a bright fine material. However, this method cannot effectively treat the surface of the workpiece when the surface of the workpiece has rolling marks and scabs. On the other hand, if the surface is machined by the same amount, the grinding efficiency is low. When rolling defects exist on the inner surface of the tube blank, the tube blank can only be modified or scrapped because the grinding method cannot effectively treat the tube blank. The deep hole boring is used for machining after the gauge is changed, and machining along bending cannot be realized during machining, and only linear machining is realized, so that the machining amount of the wall thickness in the unit length direction is required to be removed, namely, the machining amount is more than 2/1000. For example: when the length of the tube blank is 10 meters, the single-side working amount is 20mm, thereby causing the cost of the tube blank to rise.
