Selection of cemented carbide saw blade (5)

Aperture selection

Aperture is a relatively simple parameter, which is mainly selected according to the requirements of the equipment, but in order to maintain the stability of the saw blade, it is best to choose equipment with a larger aperture for the saw blade above 250MM. Domestic design of standard parts of the aperture, 120MM and the following diameter of 20MM hole, 120-230mm is 25.4mm hole, more than 250 for 30 aperture, some imported equipment also has 15.875mm hole, multi-slice saw mechanical aperture is relatively complex, more with keyway to ensure stability. No matter the size of the aperture, can be modified by a lathe or a line cutting machine, the lathe can be set in a large aperture washer, line cutting machine can reaming for equipment requirements.

A series of parameters such as type of alloy cutter head, material of matrix, diameter, number of teeth, thickness, tooth shape, Angle and aperture are combined into the whole of hard alloy saw blade. Only by reasonable selection and collocation can its advantages be better played.
