2, the β three elements should strict control reach the design accuracy requirement, to guarantee the uniformity of rise per tooth.Be shaped on a rectangular recess in the lower arcuate surface centre position that with O is the milling cutter of the garden heart, left and right two ends respectively are provided with an arc boss.After the two ends, the arc cutter hub left and right sides that constituted according to the project organization size in 60 ° of scopes are respectively removed 2 millimeters, be shaped on 39 teeth on it, 1.25 millimeters of total rise per tooths are at R
3Have 4 through holes on the cutter hub at formation camber line place.When making this milling cutter, remove R, R
2With O
1Outside the heart body plan of garden, the setting of all the other physical dimensions and technical parameter all is that implement at the center with O.
The Arc-shaped milling cutter that on key mill teeth machine, adopts the utility model to provide, because its making center and mounting center are taked unpack format, guaranteed the uniformity of cutter body and I, II type cutter combination back rise per tooth, so can realize and reach the purpose of mill teeth machining accuracy height; Preferred because of the change of milling cutter construction and technical parameter again, make it not only have higher mechanical properties, and have excellent cutting abilities such as cutting edge is sharp and shock-resistant concurrently, thus processing surfaces of keys roughness height, and cutter life, more former cutter was enhanced about more than once.
Introduce the utility model optimum implementation and install and use situation below by the accompanying drawing illustrated embodiment is detailed.
