Description

Diamond cup type grinding wheel convenient for chip removal

Technical Field

The utility model relates to a make things convenient for diamond cup type emery wheel of chip removal.

Background

Diamond cup type emery wheels are generally used for deep processing applications such as glass, ceramics, rock plates, edge grinding and polishing, and the like, and the existing diamond emery wheels include: the straight flute, the outer flute, the inner flute, the composite flute and other chip removal flutes aim at facilitating chip removal, increasing cooling effect, reducing friction between a grinding surface of a diamond matrix and a processing surface and prolonging the sharpness and service life of the grinding wheel in the grinding process of a working layer of the diamond grinding wheel.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome diamond cup type emery wheel among the prior art and rotate the not smooth defect of thing chip removal at a high speed again, provide a make things convenient for diamond cup type emery wheel of chip removal.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model provides a diamond cup type emery wheel of convenient chip removal, includes grinding wheel base member and sets up the emery wheel matrix working layer on grinding wheel base member, has seted up a plurality of helicla flutes or chutes the same with the emery wheel direction of rotation on emery wheel matrix working layer, and the degree of depth and the length of helicla flute or chute all run through emery wheel matrix working layer.

Furthermore, the width of the spiral groove or the inclined groove is 2-10 mm.

Furthermore, the degree of the spiral groove or the inclined groove is set in the range of 30-180 degrees and the carcass of the diamond working layer is distributed, and the degree is usually set to be 60 degrees, so that the effect is good, as shown in fig. 1: the oblique angle A-B is 60 degrees, the chip removal effect at the rotating speed of the existing equipment is good after repeated tests of 60 degrees, the groove type degree can be increased or decreased according to the rotating speed of a motor of the equipment, and preferably, a through grinding wheel matrix working layer with the depth of a spiral groove or an inclined groove being 6-10mm is arranged. The number of the grooves is not determined according to the diameter of the grinding wheel, generally, 48 to 56 grinding wheels with the diameter of 150 mm are fine teeth, and 32 to 36 grinding wheels with the diameter of 32 to 36 mm are coarse teeth. The diameter of phi 175 is usually set between 64 and 96, the effect of chip removal by multiple chip removal grooves is relatively better, under the condition of not influencing the service life, the diameter of phi 175 is usually set as much as possible, and the fine teeth and the coarse teeth are respectively: generally, the processing work is to process the thin teeth for the thin plates, the chip grooves are formed in a large number, the effect of increasing the width of the chip grooves is good when the thick teeth for the thick plates are processed, and in short, the width, the number and the degree of the chip grooves can be increased or decreased according to the use condition of processing and grinding. Furthermore, the cross section of the spiral groove or the inclined groove is U-shaped or V-shaped, so that the aim of smooth chip removal can be fulfilled.

Preferably, the spiral grooves or inclined grooves are uniformly distributed on the working layer surface of the tyre body.

The utility model discloses the beneficial effect who reaches is:

the utility model discloses set up a plurality of helicla flute or chute the same with emery wheel direction of rotation and can improve diamond grinding wheel chip removal smoothly, cool off not good, the sharpness is not good etc. technical problem on emery wheel matrix working layer, also improved emery wheel 30% life simultaneously. When the spiral groove or the chute generates grinding processing with a working surface in high-speed rotation, the grinding particles and powder can be smoothly discharged because the groove shape is smooth along the grinding wheel in the rotating grinding process, and the chip removal mode of completely penetrating the spiral groove or the chute functional groove avoids that the grinding wheel generates heat because of the incapability of smooth cooling water, so that the best grinding effect cannot be achieved. The spiral groove or the run-through chute is arranged along the rotating direction of the grinding wheel, so that not only can the chips be smoothly discharged and the cooling effect be good, but also the front friction between the notch of the diamond working layer and the machined surface is reduced, the products machined by the diamond grinding wheel are basically brittle materials such as glass, ceramics, rock plates and the like, the notches of the straight groove and the run-through groove collide with the machined surface in the machining process, the machined surface is easy to explode, and the internal groove, the external groove and the opposite explosion edge are improved to some extent and have poor cooling chip discharge effects. The utility model discloses a spiral link up chip groove has avoided above technical problem.
