Description

Rotary powerful chip breaker cutter

Technical Field

The utility model belongs to the technical field of machining, concretely relates to powerful chip-breaker groove cutter of gyration type.

Background

PCD, i.e. polycrystalline diamond, is a novel superhard material sintered at the high temperature of 1400 ℃ and the high pressure of 6GPa, and the hardness of the superhard material can reach 10000HV. PCD has the excellent characteristics of high hardness, strong stability, good wear resistance, high cutting precision and the like, and is widely applied to various industries such as woodworking, electronics, aviation and the like. PCD materials are the hardest materials except natural diamond in the world nowadays, related cutters usually have no chip breaker groove, but when a reamer without the chip breaker groove is processed at high speed, cutting chips are discharged backwards along a front cutter surface (the upper surface of a cutting edge) and are not easy to break, so that very long cutting chips can appear, and the long cutting chips are easy to wind on a main shaft of a machine tool along with the high-speed rotation of the machine tool, so that the machine tool is stopped or the hole wall is scratched, and accident potential hazards are formed.

the utility model provides a powerful chip-breaker cutter of gyration type, including the flange handle of a knife, adjustable cutter body, alloy cutter body and the PCD tool bit group that connect gradually, PCD tool bit group includes 2 at least PCD tool bits that connect gradually, be equipped with 1 at least cutting part chip breaker groove on the PCD tool bit.

If gyration type powerful chip breaker cutter, PCD tool bit group includes 2 PCD tool bits that connect gradually, be equipped with 2 on the PCD tool bit and follow the cutting part chip breaker of the axis symmetric arrangement of PCD tool bit.

If gyration type powerful chip breaker cutter, the cutting part chip breaker includes first step groove and second step groove, first step groove is followed the cutting direction of PCD tool bit arranges, second step groove distribute in on the first step groove and with the axis syntropy of PCD tool bit arranges.

For the rotary powerful chip breaker tool, the distance between the second stepped groove and the head end of the PCD cutter head is 1/3 of the total length of the PCD cutter head.

For example, in the rotary powerful chip breaker tool, the transition surface between the upper and lower step surfaces of the first step groove and the transition surface between the upper and lower step surfaces of the second step groove are both inclined surfaces.

For the rotary strong chip breaker groove cutter, the included angle between the inclined plane between the upper step surface and the lower step surface of the first step groove and the horizontal plane is 45 degrees, and the included angle between the inclined plane between the upper step surface and the lower step surface of the second step groove and the horizontal plane is 60 degrees.

For the rotary powerful chip breaker tool, the end part of the alloy tool body is provided with a measuring ring.

The utility model discloses technical scheme's beneficial effect is:

after the chip breaking grooves are machined in the cutting edges of the reamer, the flow direction of chips can be changed when the reamer cuts a workpiece, the chips are automatically broken after a certain length is achieved, the broken chips are cleaned through a cooling system of a machine tool, and accident potential hazards such as shutdown and the like caused by the fact that the machine tool main shaft is wound by cutting are effectively avoided.
