Abstract

The utility model provides a shank cutter of a front groove, which comprises a cutter body, a surface at a front angle of a cutting edge and a surface at the bottom of a chip pocket on the cutter, wherein the surface at the front angle of the cutting edge and the surface at the bottom of the chip pocket on each cutter are respectively provided with a set of channels, grooves, nests or pits which play a part in machining, cooling and lubricating. The cross sections of random directions of the channels, the grooves, the nests or the pits are respectively to be quadrate, ladder-shaped, semicircular, arc, elliptic, V-shaped or conical. The channels, the grooves, the nests or the pits play an important part in cooling and lubricating the cutting edge of the cutter due to the cooling vortex pressure flow generated by the mutual effect between the channels, the grooves, the nests or the pits on the front surface of the cutting edge of the cutter and cooling and lubricating liquid during machining, so that the phenomena that the cutter is thermally worn and burnt during the metal material, particularly the titanium alloy material milling process, are solved, the machining precision and progress are improved, and the thermal wear-resistant degree of the shank cutter is improved at least by more than one time as the thermal wear-resistant degree of the cutter made from the same material.

Description

The anterior canal slotting end mill

Technical field

The utility model belongs to metal material Milling Process cutting-tool engineering field, relates to a kind of improvement of slotting cutter.

Background technology

Cutter efficient low-consume in the metal cutting field be now cutting-tool engineering and process technology means all round exploration practice and the development and perfection constantly of this target.And the thermal wear phenomenon that cutter occurs in working angles has reflected real cutter level; nowadays do in the Milling Processes on the solid carbide end mill work in-process heart equipment; no matter how the geometric angle of cutter material and Tool in Cutting changes, and the cutter self-condition does not possess the action function that the cooling and lubricating protection that initiatively gets access to the processing cooling system is arranged.

Existing slotting cutter cutting edge front surface does not have the groove of cooling and lubricating elaboration, thereby in the process of work in-process heart equipment Milling Process, the cutting edge position of Tool in Cutting can not obtain cooling fully and lubricated, cause the thermal wear of Tool in Cutting sword, can not control and reduce the processing thermal wear of its cutting edge effectively, the cutter phenomenon appears burning easily, thereby machining accuracy and processing progress have been influenced, simultaneously also influence cutter service life and use cost in process of production, influenced the Milling Process technology level.

Summary of the invention

The purpose of this utility model is to solve and control the heat in metal cutting wearing and tearing that metal cutting temperature that slotting cutter produces causes the cutter cutting edge effectively and burn the cutter phenomenon in metal material Milling Process production process, make its blade in the high-speed cutting motion process, obtain cooling fully, a kind of anterior canal slotting end mill is provided with lubricated.

The anterior canal slotting end mill that the utility model provides, comprise angle surface and chip pocket lower surface before the cutting edge on cutter hub, the cutter, it is characterized in that offering one group of ditch, groove, nest or hole of playing the cooling and lubricating elaboration respectively on the angle surface and chip pocket lower surface before the cutting edge on described each cutter.

The section that cuts of any direction in described ditch, groove, nest or hole is square, trapezoidal, semicircle, arc, ellipse, V font or taper shape.

Described ditch, groove, nest or hole are from the cutting edge position of Tool in Cutting from shallow to deep.

Advantage of the present utility model and good effect:

(1) groove of the utility model Tool in Cutting sword front surface, nest or the hole cooling whirlpool pressure current that in process, interacts and generate with cooling and lubricating liquid, make it play cooling and lubrication efficiently to the cutter cutting edge, having solved in metal material, particularly the titanium alloy material milling process cutter defibrator process undermines and burns the cutter phenomenon, improved machining accuracy and processing progress, its heat-resisting degree of wear is compared with the cutter of equivalent material and is more than doubled.

(2) the anterior canal slotting end mill is under the high-speed milling state, Tool in Cutting sword and being cut between the metal fillings of metal, because the effect of cooling whirlpool pressure current, metal fillings moment can be flown away from the cutting edge of cutting tool, reduced metal fillings in the working angles and mill sassafras and flow of metal between the Tool in Cutting sword, made the Tool in Cutting sword obtain efficient and more cooling and lubricated, easily chip removal in dynamical state following moment of high-speed cutting, cut laborsaving, the service life of having improved cutter.

(3) the anterior canal slotting end mill is the titanium alloy material dedicated tool that combination property is stronger in the process, when the processing and milling titanium alloy material, compare with other existing cutters save time durable, working (machining) efficiency can improve 1 ~ 2 times, improves and progressively perfect Milling Process technology level.
