The machining tool and the machining method have the advantages that scrappage of a great amount of tools, caused by heat treatment, is avoided effectively, qualification rate is up to more than 99%, machining efficiency is improved greatly, time of the machining method accounts for 1/5-1/8 of that of a method, whereby tooth grooves are ground directly by a tool grinder after heat treatment, and machining cost of the tools is reduced greatly.
Description
Technical field
The present invention relates to a kind of processing tool and processing method thereof of ultra-fine cutter teeth groove, belong to the mechanical processing technique field.
Background technology
At present, the processing method of ultra-fine cutter teeth groove generally has two kinds.The first processing method is processed according to general cutter, before heat treatment, uses milling machine milling teeth groove, uses the tool grinding machine grinding after the heat-treatment quenching tempering.Because such cutter is too thin, therefore use this kind of method to be processed, there will be the phenomenon of cutter gross distortion after heat treatment, and can't repair while causing the tool grinding machine grinding, thereby cause product percent of pass extremely low, having a strong impact on the payment of product.The second processing method is that cutter did not carry out the milling teeth groove before heat treatment, after heat treatment, directly with tool grinding machine, carried out the grinding teeth groove.Because tool grinding machine does not have cooling system, therefore in process, the amount of feeding is slightly larger will cause the annealing of cutter blade, thereby causes cutter to scrap, and working (machining) efficiency is extremely low.In addition, such cutter of some spiral alveolars, adopting second method to be added man-hour, because tool grinding machine does not have the spiral fluted grinding attachment, carries out with workman's experience and gimmick, so the spiral fluted dimensional accuracy can't guarantee at all entirely.Although numerical control knife sharpener has good processing characteristics and good cooling system, due to the clamping that can't carry out such cutter, so do not adopt numerical control knife sharpener to be processed always.
Summary of the invention
The processing tool and the processing method thereof that the purpose of this invention is to provide a kind of ultra-fine cutter teeth groove, with crudy and the working (machining) efficiency that improves such cutter, thus the once friendship inspection qualification rate of raising converted products.
Technical scheme of the present invention: the processing tool of ultra-fine cutter teeth groove, the counter center clamping is on the folder tank of numerical control knife sharpener, the top clamping of Special reverse is on tailstock, the tailstock clamping is on numerical control knife sharpener, the conical surface at cutter two ends respectively clamping on counter center and the top anti-nest of Special reverse, be provided with clamping device on cutter, this clamping device is connected with counter center.
Described clamping device comprises fork-shaped clip, locating piece, jackscrew assembly and little clamp, wherein the fork-shaped clip is assemblied on counter center by screw, locating piece is positioned at the fork groove of fork-shaped clip and is affixed on the inboard of fork groove by screw, and locating piece is connected with the jackscrew component assembling by nut, little clamp is fixed on the lower end of jackscrew assembly and is connected with tool assembly.
A kind of processing method of ultra-fine cutter teeth groove comprises the following steps:
(1) will not carry out the cutter heat treatment of milling teeth groove;
(2) two ends of cutter are ground to the conical surface;
(3) by tool assembly on frock, adjust position;
(4) the teeth groove parameter of cutter is set on numerical control knife sharpener;
(5) initial manufacture: when first cutter of such cutter of processing, by the feeding speed of emery wheel and grinding depth parameter value, establish low, the tool grinding platform upper surface top to Special reverse while making grinding, after machining, the platform upper surface of counter center forms and the identical grooved of such cutter teeth groove;
(6), since second cutter, with normal feeding speed, processed, until such all tool sharpenings are complete.
Beneficial effect of the present invention: the processing tool and the processing method thereof that adopt this ultra-fine cutter teeth groove, effectively avoided scrapping because of a large amount of such cutters that heat treatment causes, qualification rate can reach more than 99%, and working (machining) efficiency also significantly promotes, be " after heat treatment, directly with tool grinding machine, carrying out the grinding teeth groove " 1/5-1/8 in man-hour used, also therefore greatly reduce the processing cost of such cutter.
