Abstract

The invention discloses a spherical rolling and pressing cutter which comprises a cutter handle, wherein a connecting head is arranged at the head part of the cutter handle; a guide rod connected with a fixing rod on a machine tool is rotatably arranged at one end of the connecting head; a cutter head rotating in the same angle as the guide rod is arranged at the other end of the connecting head; a rolling and pressing head is fixed on the cutter head; a rolling and pressing ball retainer is slantly mounted on the rolling and pressing head; a rolling and pressing ball is mounted at the head part of the rolling and pressing ball retainer in a rolling manner; an oil inlet channel is formed in the cutter handle; an oil inlet is formed in the end part of the oil inlet channel; a connecting channel is formed in the connecting head; an oil outlet channel is formed in the rolling and pressing head; the oil inlet channel, the connecting channel and the oil outlet channel are connected to form an oil passing channel; oil flushing openings are uniformly formed in the periphery of the rolling and pressing ball retainer. The spherical rolling and pressing cutter has the advantage that the cutter head and the guide rod can rotate in the same angle along with machining tracks during a machining process, so that cutting point positions of the rolling and pressing ball and a machined workpiece are always kept unchanged. Thus, the nonuniform stress caused by the changes of the cutting points during the machining process is avoided. As a result, the machining precision is improved.

Description

technical field [0001] The invention relates to the technical field of machining cutters, in particular to a spherical rolling cutter. Background technique [0002] Machine tool processing refers to the processing of raw materials with machine tools. Machine tool processing can be divided into ordinary lathe processing and CNC lathe processing according to different machine tools. With the continuous development of machine tool processing technology, CNC lathes have gradually replaced ordinary lathes. The use of CNC lathe processing not only improves the production effect of parts and products, but also improves the precision of processing to meet the processing needs of fine processing and precision parts. [0003] Rolling knife is a mechanical non-cutting plastic processing method that uses the principle of mechanical extrusion to obtain a mirror-like metal surface. The rolling knife can use the plastic deformation of the metal at room temperature to flatten the microsco...
