The CX100 type hard alloy circular saw blade tooth top surface CNC sharpening machine tool produced by VOLLMER Machine Tool Company of Germany adopts CNC four-axis linkage, which provides the basic conditions for sharpening complex tooth shape. The main features of the machine tool are short sharpening time, high machining precision and compact structure. The PMC micro-processing control system creates conditions for most machining applications; a small amount of data input and graphic support guides make operation easier; Any tooth shape of the surface can be sharpened in one machining cycle; four kinds of complex tooth shapes with different oblique angles and tooth heights can be sharpened; the sharpening speed and the sharpening stroke of each sharpening surface can be steplessly adjusted; The fully enclosed structure can effectively prevent dust and the sharpened part of the sharpening part can meet the requirements of sharpening precision. Four-axis control increases machine suitability Different grinding speeds and paths for better quality of the ground surface
