Description
Technical field
The present invention relates to cutter processing, refer to a kind of processing method of cutter and the grinder of milling cutter especially.
Background technology
Seeing also shown in Figure 11ly, is the process block diagram of general known cutter machining method.It mainly is earlier the cutter of blade and chip removal groove to be provided in a stock milling, and then the cutter after this milling is carried out the cure process of modes such as sputter, to increase the hardness of this cutter.
See also shown in Figure 12ly, cutter 1 surface after this milling has some trickle and sharp keen cut channels 10, produces when those cut channels 10 are the milling cutter milling, and forms a recess 11 respectively between those sharp keen cut channels 10.
Seeing also shown in Figure 13ly, is to find out that the cutter 1 after mode with sputter is to this milling carries out cure process, is to plate a hardened layer 12 in the surface of this cutter 1.This hardened layer 12 is thin in the extreme, so it can't fill up the recess 11 between those sharp keen cut channels 10, and can make this cutter 1 surface still present scraggly situation after cure process.
The scraggly situation of this tool surface can increase frictional resistance and cutting and chip removal are comparatively had some setbacks, and then makes this cutter easily produce long-pending heat and crumble and can influence cutting effect.So its service life is short and efficient cutting is also relatively poor, and more owing at present under the requirement that becomes accurate is healed in the milling of 3c industry computer (Computer), communication (Communications) and consumer electronics (Consumer-Electronics r), solve the rough and uneven in surface also ever more important of tool surface.
Summary of the invention
Technical problem to be solved by this invention is, at the deficiencies in the prior art, the cutter machining method that provides increase a kind of service life that makes cutter and the stock-removing efficiency of this cutter is improved, and a kind of grinder that tool lapping can be gone out smooth surface and can make the comparatively stable milling cutter surface of the quality of grinding is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of cutter machining method comprises the following steps:
(a) milling: the cutter of a stock milling being provided blade and chip removal groove;
(b) grind: the trickle and sharp keen cut channel that this tool surface produced after the milling is polished; And
(c) cure process: this cutter is carried out cure process.
And a kind of grinder of milling cutter, comprising:
One board has a pedestal and a support body, and this support body is vertical on this pedestal;
One grinding drum is located on this pedestal rotationally, and an opening that has up can be for inserting abrasive;
One CD-ROM drive motor is located at and can be driven this grinding drum rotation on this pedestal; And
One clamping device is incorporated on this support body, and is positioned at this grinding drum top, can supply the some cutters of clamping, and make the rotation in this grinding drum of those cutters.
So, the trickle and sharp keen cut channel that this tool surface produced after the milling being polished or the rounding cunning by this grinding steps is first, and then this cutter is made cure process, is to make the surface of this cutter comparatively smooth.Known cutter after the milling is directly made the rough problem of tool surface that cure process is produced to improve.And the cutter that the surface that this present invention finished is comparatively smooth can make cutting and chip removal more smooth and easy especially, and make it therefore have long service life and stock-removing efficiency, and still might produce new burr after the sclerosis,, guarantee that cutter is smooth so sclerosis back cutter still can be returned polish process.The design that the present invention makes the rotation in this grinding drum of those cutters by rotation and this clamping device of this grinding drum, can make the abrasive in this grinding drum produce mobile fast, with with the surface grinding of cutter comparatively evenly and careful, and make the surface of this cutter comparatively smooth.In addition, system can control the rotating speed of this grinding drum and this cutter accurately by this CD-ROM drive motor and this clamping device, and makes the quality of grinding can be comparatively stable.
