Classification and machining methods for end teeth of three sided milling cutters
2023-01-10
Three sided milling cutter: mainly used for milling grooves of fixed size, as well as general grooves, step surfaces, and side surfaces. Characteristics and degree: Different from ordinary milling cutters, the three cutting edges have a back angle, sharp edges, and light and fast cutting. Knife body 40Cr, blade made of hard alloy; K20 (YG6) is used for processing cast iron, and P20 (YT14) is used for processing steel parts. The parts of the end face close to the outer circle have cutting edges that are wider and serrated; The main cutting edge of a three sided milling cutter is distributed on the cylindrical surface of the milling cutter, and the secondary cutting edge is distributed on the two end surfaces; Adjustable and indexable hard alloy staggered tooth three sided milling cutter is used to process grooves, which can compensate for the reduction in width size after blade wear and reduce the width specification of the milling cutter. If appropriate cutting amount is selected, various grooves can be milled in one go, with a degree of HS and good smoothness. It has the characteristics of high efficiency, long service life, low cost, steel saving, and easy inspection.
A three sided milling cutter not only has a main cutting edge on the circumferential surface, but also secondary cutting edges on both sides, thereby improving cutting conditions, increasing cutting efficiency, and reducing surface roughness. Mainly used for milling step and groove surfaces of medium hardness and strength metal materials, and can also be used for machining non-metallic materials. Hard material three sided milling cutters are used for milling step and groove surfaces of difficult to cut materials. Mainly used for milling grooves of fixed size, as well as general grooves, step surfaces, and side surfaces.
