Abstract
The utility model relates to the technical field of a machining cutter and particularly relates to a rough milling knife. The rough milling knife comprises a knife handle for clamping and a cutting part arranged at one end of the knife handle, wherein the cutting part comprises four end face edges which are arranged on the front end face of the knife handle, and four straight-line edges which are distributed along the periphery of the knife handle in a straight-liner manner; each end face edge is correspondingly connected with one straight-line edge; each end face edge and each straight-line edge are connected through a transition circular-arc edge; and a chip removal groove is formed between the adjacent straight-line edges. When the rough milling knife is used for roughly milling a workpiece, metal chips can be smoothly discharged out from the chip removal groove; and the rough milling knife is simple in structure, can conveniently and rapidly carry out rough milling on the workpiece needing to be milled, and can provide reliable guarantees to follow-up fine milling.
Description
Technical field
The utility model relates to the machining tool technical field, is specifically related to a kind of tertia cutter.
Background technology
In the machining, workpiece is being added man-hour, for the precision that guarantees the workpiece milling and the quality of product, needing to adopt the tertia cutter carry out preliminary milling to workpiece in advance, and then carry out finish-milling with high-precision cutter.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of tertia cutter simple in structure, and it can be rough milled workpiece.
The realization the technical solution of the utility model is as follows:
A kind of tertia cutter, comprise the handle of a knife for clamping, be arranged on the cutting tip of handle of a knife one end, described cutting tip comprises four end face swords that are arranged on the handle of a knife front end face, and along four straight line swords of handle of a knife side face straight line, be connected by a transition arc sword between the corresponding straight line sword that connects of each end face sword, described end face sword and straight line sword, form chip area between the adjacent straight line sword.
The radius of described transition arc sword is 1mm.
The axial length of described cutting tip is 20mm, and the length of shank portion is 30mm.
The diameter of described handle of a knife is 16mm.
Adopted such scheme, when workpiece is rough milled, milling part of the present utility model, end face sword, transition arc sword and straight line sword carry out milling to workpiece, the metal fillings that mills out is discharged from chip area, owing to adopting the straight line sword, metal fillings can be discharged from chip area smoothly; The utility model is simple in structure, can conveniently rough mill the workpiece that needs milling, and reliable assurance can be provided for the finish-milling of postorder.
