Abstract
The utility model discloses a ceramic slotting abrasive wheel. Open slots, which are the same in shape and size, are uniformly formed in one or two plane surfaces of a planar abrasive wheel, and are t in depth, a in width, and b in length, wherein t equals to one fourth to one third of T; a is 4 to 8 mm; b equals to one second to two thirds of (R-r); R is the semi-diameter of the abrasive wheel; r is the semi-diameter of an abrasive wheel hole; T is the thickness of the abrasive wheel. The utility model is suitable for ceramic abrasive wheels, of which the external diameter D is equal to or larger than 500 mm and the thickness T is equal to or larger than 80 mm. As the depth of the open slots is only one fourth to one third of the thickness of the abrasive wheel, the strength and the safety performance of the abrasive wheel are not impacted; the heat radiation, chip removal and grinding effects of the abrasive wheel are better during grinding; the trimming frequency is reduced; the service life of the abrasive wheel is effectively prolonged; the effect is particularly obvious when the ceramic slotting abrasive wheel is used for grinding materials difficult to grind or special workpieces, and the effect is more obvious.
Description
Technical field
The utility model relates to the vitrified abrasive of slotting in a kind of plane.
Background technology
Ceramic flat surface emery wheel is very extensive especially for cylindricalo grinding in mechanical grinding processing industry.Conventional ceramic flat surface emery wheel is the intensity that guarantees emery wheel, its two plane is complete circular configuration, in the time of grinding work piece, be the continuous grinding mode adopting like this, the pore of emery wheel easily stops up, be unfavorable for chip removal and heat radiation, particularly grinding some during as difficult grind materials such as titanium alloys, can only rely on continuous finishing to meet processing request, both affect grinding efficiency, reduced again the service life of emery wheel.There is producer to use the porosity that strengthens emery wheel to solve, but not fairly obvious because considering this effect of wheel strength." being provided with equally distributed, shape and radial opening groove of the same size at the periphery position of flat-faced wheel " proposed in documents 200720044954.8, this method can only be applicable to that emery wheel external diameter is less than 450mm, thickness is less than the vitrified abrasive below 75mm, for the vitrified abrasive that diameter is large, thickness is thicker, be certain to affect wheel strength, cause using dangerous.
Utility model content
The purpose of this utility model is to solve major diameter, high thickness ceramic flat surface emery wheel dispels the heat in the time of cylindricalo grinding and chip removal effect is bad, pore easily stops up, grinding efficiency is low problem, provides a kind of and is conducive to that heat radiation and chip removal, grinding efficiency are high, the ceramic slotted wheel of long service life.
The technical solution of the utility model is: a kind of ceramic slotted wheel, its improvements are to be radially provided with in one or two plane of flat-faced wheel and are uniformly distributed, shape and open slot of the same size, degree of depth t=1/4～1/3T, the width a=4～8mm of described open slot, length are b=1/2～2/3 (R-r), wherein R is grinding wheel radius, r is emery wheel pore radius, and T is grinding wheel thickness.Described open slot quantity is at grade 24～64.
Further scheme is: the distribution of described open slot in two planes staggered by a hemihedrism of angle between adjacent two open slots.
The utility model is reasonable in design, novel structure.Described open slot can be set according to the size of emery wheel external diameter, material, hardness, is adapted to all kinds of materials of D outer diameter >=500mm, thickness T >=80mm and the vitrified abrasive of granularity.Because the degree of depth of open slot only has 1/4～1/3 of grinding wheel thickness, do not affect intensity and the security performance of emery wheel, simultaneously because there being the existence of groove, emery wheel dispels the heat in the time of grinding and chip removal better effects if, ground effect are even more ideal, reduce finishing number of times, the service life of emery wheel, particularly grinding some difficult grind materials or when special workpiece, effect is more obvious are effectively improved.
Accompanying drawing explanation
Accompanying drawing is depicted as structural representation of the present utility model.
The specific embodiment
Embodiment 1: referring to accompanying drawing, the code name of ceramic flat surface emery wheel 1 is: 1-750*80*305-WA/F120P6V-45m/s, a plane is provided with 36 radial opening grooves 2, the degree of depth t=24mm of open slot, width a=6mm, length b=130mm therein.The intensity of emery wheel can be controlled national standard and detect by 45m/s, does not affect safe handling.
Embodiment 2: referring to accompanying drawing, the code name of ceramic flat surface emery wheel 1 is: 1-900*100*305-PA/F100M6V-35m/s, in two planes, be equipped with 48 radial opening grooves 2, distribution in two planes is staggered by 3.75 degree symmetries, the degree of depth t=30mm of open slot, width a=5mm, length b=170mm.The intensity of emery wheel can be controlled national standard and detect by 35m/s, does not affect safe handling.
Claims (3)
1. a ceramic slotted wheel, for flat-faced wheel, it is characterized in that being radially provided with in one or two plane of flat-faced wheel be uniformly distributed, shape and open slot of the same size, degree of depth t=1/4～1/3T, the width a=4～8mm of described open slot, length are b=1/2～2/3 (R-r), wherein R is grinding wheel radius, r is emery wheel pore radius, and T is grinding wheel thickness.
