Abstract
The utility model discloses an improved milling cutter, which comprises a cutter handle, a cutter body and a cutter bit. Two ends of the cutter body are connected with the cutter bit and the cutter handle respectively, a spiral cutter bar is arranged at one end of the cutter body close to the cutter bit, a chip flute is arranged on the cutter bar, mutually communicated liquid flow holes are arranged on the cutter handle and the cutter bar along a horizontal center line, outlets of the liquid flow holes are arranged in the chip flute, and a plurality of saw teeth are arranged on the cutter bar along a spiral surface. The improved milling cutter has the advantages that cutting precision is high as the saw teeth are arranged on the spiral cutter bar along the spiral surface, chips generated in cutting can be conveniently and timely cleaned as the chip flute is arranged on the cutter bar, cooling liquid flows through the cutter body via the liquid flow holes to timely and effectively cool down the cutter bar and the cutter bit as the outlets of the liquid flow holes are arranged in the chip flute, and the cutter can be conveniently tightly mounted on a machine as process grooves are arranged on two sides of the cutter body.
Description
Technical field
The utility model relates to a kind of improved milling cutter, belongs to field of machining.
Background technology
Blade shapes has a variety of, and usually milling cutter is applied in hole processing and processes with die cavity, will carry out roughing earlier generally speaking man-hour adding; Change milling cutter then and carry out semifinishing; And then change milling cutter and carry out fine finishining, workpiece just can meet the requirements like this, often changes milling cutter; It is loaded down with trivial details to work, inefficiency.Therefore, need provide a kind of new technical scheme to solve the problems referred to above.
The utility model content
The purpose of the utility model provides a kind of simple to operate, improved milling cutter that precision is high.
The technical scheme that the utility model adopts is:
A kind of improved milling cutter; Comprise handle of a knife, blade and cutter head, said blade two ends connect cutter head and handle of a knife respectively, and said blade is provided with the spirality knife bar near cutter head one end; Said knife bar is provided with chip area; Said handle of a knife and knife bar are provided with the liquid flow hole that is interconnected along cross central line, and the outlet of said liquid flow hole is located in the chip area, and said knife bar upper edge helicoid is provided with a plurality of sawtooth.
The cross-sectional diameter of said handle of a knife is the 1/3-1/2 of blade cross-sectional diameter.
Said blade both sides have technology groove.
The groove depth of said technology groove is the 1/6-1/4 of blade cross-sectional diameter.
The beneficial effect of the utility model: the spirality knife bar, knife bar upper edge helicoid is provided with a plurality of sawtooth, and this structure cutting precision is high; Knife bar is provided with chip area, the scrap that produces when being convenient in time to clean out cutting, and the outlet of liquid flow hole is located in the chip area, and cooling fluid is in time cooled off knife bar and cutter head, good cooling results from the liquid flow hole blade of flowing through; The blade both sides have technology groove, are convenient to install step up on machine.
