Tungsten Carbide Facing Cutter
Introduction
Tungsten carbide facing cutter generally mounted by throw-away carbide tipped blade. The cutter mounted on the machine spindle and the carbide blade pressed against the cutter by the wedge block. It has high cutting efficiency and cutting accuracy, so it plays an important role in mechanical process.
Structure
Common face cutter consists of blade seat, support ring, plate cutter, cutter, cutter body, the outer ring, pin, inner hexagon fastening screws. The blade can be coupled with the seat by bolts, and also processed into a whole, which depends on the cutting force of face cutter. There are many grooves around the cutter, and each of them has an inner and outer groove. And it has threaded hole on the groove accordingly for screw installing and clamping the blade. According to the turning direction of engaged gear and cutter, the teeth arranged in accordance with certain rules.
