Abstract

The utility model relates to a cutter for turning grinding wheels, which is characterized by comprising a cutter rod, wherein the upper front portion of the cutter rod is provided with an inclined plane which is concavely provided with a circular blade made from artificial polycrystalline diamond composite material, the head portion of the blade is projected out of the cutter rod, and the blade is fixed on the cutter rod by a mushroom screw. When the cutter is used for turning inner holes, the cutter rod is in a cylindrical shape, the upper surface and the lower surface of the cutter rod are respectively processed with a plane, and the cutter rod is in a square column form when the cutter is used for turning excircles. The blade made from artificial polycrystalline diamond composite material in the utility model has the hardness which is only inferior to natural diamond and can reach HV9000, and the price of the blade is far slower than the natural diamond. When the cutter is used to turn the grinding wheels, the cutter has over 5 hours of durability, 1/1,300,000 volume abrasion wear, and over 5 times of turning efficiency than the traditional turning efficiency. The utility model can be widely used in the turning process of various grinding wheels.

Description

A kind of cutter that is used for the turning emery wheel
Technical field
The utility model relates to a kind of cutter of processing grinding wheel, particularly about a kind of cutter that is used for the turning emery wheel.
Background technology
Generally speaking, after emery wheel solidified through roasting, its size, shape and positional precision did not all reach instructions for use, must be through further processing.Such as because of the emery wheel off-dimension, just need change size turning to emery wheel.Because the hardness of emery wheel abrasive material is very high, generally in HV2400~3500, therefore the size turning that changes to emery wheel often becomes hang-up.Because odjective cause in the prior art, to the processing of emery wheel, mostly adopts traditional crushing wheel turning both at home and abroad.Take this turning process, dust is big during turning, noise is high, working (machining) efficiency is low, and labor strength is big, and the comprehensive process cost is also higher.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of turning efficient height, and is effective, the lower-cost cutter that is used for the turning emery wheel.
For achieving the above object, the utility model is taked following technical scheme: a kind of cutter that is used for the turning emery wheel, it is characterized in that: it comprises a knife bar, the top front portion of described knife bar has an inclined-plane, in described inclined-plane, be concaved with the circular shear blade that a man-made polycrystalline diamond composite is made, described blade head is given prominence to described knife bar, with a mushroom screw described blade is fixed on the described knife bar.
Described knife bar is cylindric, and the upper and lower faces of described knife bar processes a plane respectively.
Described knife bar is flat column.
The utility model is owing to take above technical scheme, it has the following advantages: 1, the utility model is because the blade (PCD) that adopts the man-made polycrystalline diamond composite to make, its hardness is only second to natural diamond, can reach HV9000, but price is but far below natural diamond, and when using the utility model cutter turning emery wheel, the durability of cutter can reach 5 hours, the volume wear resistance ratio can reach 1,/13,000,000, and turning efficient is more than 5 times of traditional turning efficient.2, the utility model is owing to be made into disc machinery clamped tool with blade, can make therefore that cutter cuts out steadily in the turning process, prevented effectively fragility the emery wheel generation collapse limit phenomenon generation.The utility model can be widely used in the various emery wheel turning processes.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1 and Figure 2, present embodiment is one to be used for the cutter 1 of car endoporus, and it comprises a columniform knife bar 11, processes a plane 12,13 respectively at the upper and lower faces of knife bar 11.12 front portions, plane are provided with an inclined plane 14 on knife bar 11, in inclined plane 14, be concaved with the circular shear blade 15 that a man-made polycrystalline diamond composite is made, circular shear blade 15 heads are given prominence to knife bar 11, and with a mushroom screw 16 circular shear blade 15 are fixedly connected on the knife bar 11.
As shown in Figure 3, Figure 4, present embodiment is one to be used for the cutter 2 of turning, it comprises the knife bar 21 of a square column type, the front portion is provided with an inclined plane 22 on knife bar 21, in inclined plane 22, be concaved with the circular shear blade 23 that a man-made polycrystalline diamond composite is made, circular shear blade 23 heads are given prominence to knife bar 21, with a mushroom screw 24 circular shear blade 23 are fixed on the knife bar 21.
When the utility model used, the hardness of the circular shear blade of being made by the man-made polycrystalline diamond composite 15,23 can reach HV9000, turning speed V=30~50m/min; Cutting depth ap=1~5mm; Amount of feeding f=1~1.5mm/r.Tool life can reach 5 hours when adopting the utility model turning emery wheel, and the volume wear resistance ratio can reach 1,/13,000,000, and its efficient is more than 5 times of traditional turning efficient.
