Description

numerical control wave edge milling cutter relief grinding machine and trimming device

Technical Field

The utility model belongs to the technical field of ripples sword milling cutter grinding machine, a numerical control ripples sword milling cutter relief grinding machine and trimming device is related to.

Background

The common milling cutter has low milling efficiency, and sometimes even can not carry out cutting operation under heavy cutting conditions, so the wave edge milling cutter with the cutting performance obviously superior to that of the common milling cutter is more and more popular with people. The peaks and valleys of two adjacent wavy edges are staggered by a certain distance along the axis, so that the cutting width is obviously reduced, the actual cutting thickness of the cutting edge is increased by about three times, the cut chips are narrow and thick, the cutting deformation degree is reduced, and the cutting edge is enabled to avoid a surface hardening layer and cut into a workpiece. The wave edge makes the inclination angle of each point edge of the cutting edge, the working rake angle and the borne cutting load different, and the tooth pitch of the wave edge in the same end section is also different. The above factors greatly reduce the periodicity of cutting force change, and the cutting tool has the advantages of light cutting speed, smooth drainage, long service life and very stable cutting process, and is particularly suitable for cutting with high surface hardness and large allowance change.

However, the machining of the wave edge milling cutter is difficult, and particularly, the machining of the tooth profile thereof, there are two main machining methods known in the art:

1. The tooth form of the wave blade is machined by relief grinding, namely, a polishing cutter is used for cutting a grinding wheel, then a relief grinding machine is used for relief grinding the wave blade, and meanwhile, a spiral groove and a relief back relief angle are formed, but the tooth form of the wave blade is in a spiral angle surface of 20-35 degrees, so that great machining difficulty is brought to relief grinding, smooth transition cannot be guaranteed at the joint of a complete tooth form and the next complete tooth form, unsmooth chip removal is brought, and machining cannot be smoothly carried out.

2. The tooth form of the wave edge milling cutter is processed by a numerical control knife grinder, the electroplated CBN grinding wheel is mostly used for the formed grinding wheel in the mode, and the grinding wheel cannot be dressed due to the electroplated layer on the grinding wheel. However, the radian and the thread pitch of the tooth form of the wave edge milling cutter are different, and even if only small differences exist among different wave edge milling cutters during use, the electroplated CBN grinding wheel needs to be replaced at any time, otherwise, the tooth form connection is not smooth enough, and the finished product smoothness processed by the wave edge milling cutter cannot meet the customer requirements. The electroplating CBN grinding wheel is replaced at any time, so that the operation is inconvenient, the working efficiency is reduced, a large amount of resources are wasted, and the cost is increased.
