Numerical control lathe most the jar of oil pressure circumgyrate that often uses has become high speed of high-ranking machine tool to change the biggest bottleneck. At present a lot of high-ranking numerical control lathe use the design that main shaft hides inside motor, main shaft rotate speed already can be broken through 10, 000r/min above, but as a result of adoption oil pressure turn because the crock heats up the problem of temperature rise, lathe limitation of real work rotate speed is in only 7, 000r/min left and right sides. Main shaft is worn from time to tome in job of high rotate speed the thorny problem that cannot overcome inherently -- , hot temperature rise. As a result of the attrition heat build-up with the circular ceaseless oil inside crock of oil pressure circumgyrate, cause temperature of main shaft system to rise, to the precision of main shaft system control is having extremely adverse effect, in addition the high temperature when working to restrain crock of oil pressure circumgyrate rises, itself of crock of oil pressure circumgyrate is indispensible increase a lot of additional designs, if come loose,heat up fin piece, and prevent the relief valve with exorbitant pressure to wait. But these problems that can solve a part only, machine tool itself still needs to install oily cooling system, reach thermal drop inside reasonable range, rise as the rotate speed demand of the machine tool, the additional cost of oily cooling system is to increase subsequently more. As miniaturization of various treatment spare parts, the tide that turns subtly, more and more tool aircraft manufacturers discover crock of oil pressure circumgyrate, apply the most generally at the clamping apparatus actuating device of industrial group at present. Chao Quan is industrial be aimed at high rotate speed, high accuracy, use flexibility collet places the lathe of small-sized numerical control of the crop that support project, the air in developing a brand-new high speed presses circumgyrate crock JAL636-PL. As we have learned, use jar of JAL636-PL baric circumgyrate, can reduce main shaft of numerical control machine tool effectively to heat up the precision error that temperature rise causes, and can reduce the cost of machine tool itself considerably. The cylinder diameter of JAL636-PL is 162mm, hollow aperture is 36mm, it is 144mm endlong, , it is the crock of high-powered baric circumgyrate with a compact appearance. Via real test, the cylinder body temperature rise when 6500r/min is in crock of JAL636-PL baric circumgyrate centigrade 8 degrees of less than, can solve the calorific problem of crock of circumgyrate of traditional oil pressure thoroughly.
