Description
Technical field
The utility model relates to the supporting emery wheel of a kind of electronic or pneumatic angle grinding machine.
Background technology
Emery wheel is the main tool of grinding, and it is the porous body that is made up of abrasive material and bond.Wherein abrasive material, bond and hole are three underlying dimensions of emery wheel.Along with the difference of abrasive material, bond and emery wheel manufacturing process etc., grinding wheel characteristics possibility difference is very big, to precision, roughness and the production efficiency important influence of grinding.Therefore, must select suitable emery wheel for use according to actual conditions.The characteristic of emery wheel is decided by factors such as abrasive material, granularity, hardness, bond, shape and sizes.Abrasive material is a primary raw material of making emery wheel, and it is undertaking cutwork.Therefore, abrasive material must be sharp, and possess high hardness, good hear resistance and certain toughness.The selection of abrasive grain is main relevant with machined surface roughness and productivity ratio.During corase grind, grinding allowance is big, and the surface roughness value of requirement is bigger, should select thicker abrasive particle for use.Because abrasive particle is thick, pore is big, grinding depth can be bigger, and emery wheel is difficult for stopping up and heating.During correct grinding, surplus is less, requires roughness value lower, can choose than fine grit.In general, abrasive particle is thinner, and grinding surface roughness better.Material in order to bonded abrasive in the emery wheel is claimed bond.The intensity of emery wheel, impact resistance, hear resistance and resistance to corrosion depend mainly on the performance of bond.Can make the emery wheel of different hardness with a kind of abrasive material, it depends mainly on the technology that performance, quantity and the emery wheel of bond are made.The external diameter of emery wheel should select more as far as possible, and is to improve the peripheral speed of emery wheel, favourable to improving grinding productivity ratio and surface roughness like this.
The angle grinding machine is that the disc wheel and the elastic grinding wheel that utilize rotation at a high speed, wire wheel etc. carry out grinding, cutting, rust cleaning, polishing processing to hardware; Be fit to be used for cut, grind and brush mill metal and stone material; Water can not be made during operation, guided plate must be used during cutting stone material.Because the manufacturing process of abrasive material, bond material and the emery wheel of emery wheel is different, various emery wheels just have the different working performance.Each emery wheel all has certain scope of application according to the characteristic of itself.Therefore; During grinding; (like material character, heat treatment method, workpiece shape, size and the form processing and the specification requirement etc. of institute's grinder part) as the case may be; Select suitable emery wheel for use, otherwise can select improper machining accuracy, surface roughness and the production efficiency of directly influencing because of emery wheel.China is the manufacture base of global angle grinding machine; All have every year millions of corner of table grinding machines to sell to all parts of the world, supporting with it reconditioning must meet the requirement of angle grinding machine with cymbals shape emery wheel: supporting emery wheel should have higher security intensity, the excellent balance performance; Outward appearance and good grinding performance preferably; The outward appearance and the grinding performance of home products can meet the demands basically at present, but security intensity and balance stability are bad, vibrations and emery wheel fragmentation occur through regular meeting.
The utility model content
