Description
Technical field
The utility model relates to the technical field of milling cutter, specifically a kind of split type maize milling cutter.
Background technology
Maize milling cutter is a kind of multiple chip unit of arranging on the periphery of cutterhead, is realized the finish-milling of to be processed by the blade gathered in multiple chip unit.Because the blade quantity on maize milling cutter is many, the sword on blade is long shorter, and therefore cutting resistance is little, thus can realize high speed, high-precision processing, replaces grinding machine operation even.And the arrangement due to its whole blade is similar in corn ear, because being commonly called as in the industry as maize milling cutter.
But meanwhile, also more just because of maize milling cutter upper knife edge quantity, when part edges damages, whole maize milling cutter cannot normally work, therefore the maintenance of maize milling cutter of the prior art and higher, the whole cutter Renewal process of maintenance cost complicated, consuming time longer.And the blade of comparatively easily damage often concentrates on the position being positioned at nearly facing cutter head in usual maize milling cutter.
