Type of multipolar electromagnetism chuck exceeds essence of life to grind the machine tool passes appraisal

On November 22, chinese mechanical Joint Industry Conference is in Beijing China hall of science and technology organized type of pair of multipolar electromagnetism chuck to exceed essence of life to grind the appraisal of achievement of science and technology of the machine tool. Appraisal conference thinks: Type of multipolar electromagnetism chuck exceeds essence of life to grind the machine tool application in bearing treatment is in banner level in home, the level of manufacturing industry of equipment of base of old to promoting northeast industry, to pushing our country from the transition of bearing big country to bearing powerful nation, will produce positive effect to urging the integral standard of our country machining then. As we have learned, at present our country bearing exceeds energy equipment overall technology is in immature phase, working procedure of essence of life exceeds in bearing in, the type pressing roller that what use generally is foreign entrance and domestic production exceeds essence of life to grind equipment, the inherent malpractice that this kind of facilities exists cannot be overcome from beginning to end. In the meantime, facilities of land of type rolling a club and the most primitive manual polish craft coexist at the same time, the surface roughness of surface of bearing raceway groove after treatment, ripple is spent, oscillatory value percent of pass is low, product accuracy class is low, competition ability is poor. Regard a country as patent product (patent date: ZL97222421 - 1) , type of multipolar electromagnetism chuck exceeds essence of life to grind the machine tool is core technology with multipolar electromagnetism chuck. Multipolar electromagnetism chuck is the replacement product that quick check embryo, bedspring blocks the traditional clamping apparatus such as chuck of electromagnetism of chuck of head, bedspring, mechanical chuck, sheet pole in machining equipment, technology that is craft of superfinishing clamping apparatus innovates, this tries whole to be in mechanical industry to popularize applied electromagnetism clamping apparatus to have demonstrative sense. The machine tool uses automatic, semi-automatic circulation, PLC control, apply multipolar electromagnetism chuck, end panel is sucked rely on not to use the device that press roller, suck with multipolar electromagnetism chuck lean, set give the magnetism, unit that return magnetism automatically, use 2 footwork to exceed essence of life, pressure of workpiece revolution, oilstone and oilstone swing frequency all is adjusted for stepless, oilstone depletes ultimate position, set call the police, stop machine safety protector, oscillation part is inertial small, frequency is tall, manipulator is used mandatory fluctuation makings device, on the safe side. Type of multipolar electromagnetism chuck exceeds essence of life to grind the machine tool has characteristic of the following and main technique: -- by workpiece of the impaction that press roller, instead attracts firm work by disk, removed the axial pressure to main shaft, solved main shaft bearing spends a question with what press roller bearing; -- the time that reduced to tool changes and be adjusted; -- use work of adsorption of multipolar electromagnetism chuck, swing through oilstone pressurization, take out essence grinds quantity, achieve workpiece surface surface roughness to reduce, improve geometrical precision, raise the goal of bearing life; -- fluctuation makings is used force type construction, stable and reliable, thick exceed essence of life undertake at the same time, improve efficiency; -- shortened the settling time of fulcrum. As torch of ministry of science and technology plan and national hair change appoint industrialization demonstrative project, at present bearing of type of multipolar electromagnetism chuck exceeds essence of life to grind the machine tool had finished prototype trial-produce and production of product small lot, undertook a machine tool function experiments and produce assessment actually, each specifications index all achieved the requirement that the project sets.
