Product Description Centerless Grinding MachineSliding table:The up and down slide table adopts a double dovetail type slide rail with embedded strip scraping to match the sliding accuracy, ensuring smooth sliding and stable operation. At the same time, the bed rail is lengthened and the grinding wheel avoids mud immersion. The upper skateboard adopts a dovetail groove structure, while the lower feed adopts a high-precision screw rod and is equipped with a fine adjustment feed device. The feed fine adjustment can reach 0.003mm/m, which is easy to use, clear in format, and fully improves operational accuracy.Spindle:Using 38GMOAVA alloy steel, it undergoes quenching and tempering, desalination heat treatment, and then computer-controlled cryogenic treatment. Its surface hardness reaches HRC62 ° or above, with a single-sided effective hardness layer of 0.25mm or more and a core of HRC30 °. It is wear-resistant and not easily deformed. Through multiple precision grinding of the central hole, tooth, and outer diameter, the precision surface is ensured and the lifespan is long.Grinding Sample:Technical Parameters:Traverse grindingGrinding diameter10~150MMmaximum grinding length250MMHorizontal feed grindingGrinding diameter10~150MMmaximum grinding length190MMWorkpiece weight10.6KGMaximum specification of grinding wheelP600*200*305Minimum specification of grinding wheelP480*200*305Maximum specification of guide wheelPSA350*200*127MMMinimum specification of guide wheelPSA300*200*127MMGrinding wheel speed1050-1150 revolutions per minute Wheel speed at work7.12.18.23.29.34.58 revolutions per minuteWhen repairing the guide wheel280 revolutions per minute 2°~5°Rotation angle of guide wheel (in vertical plane)±3°Grinding wheel corrector rotation angleRotation angle of guide wheel corrector±3°Within the vertical plane-2°~5°Within the horizontal plane15MMGrinding wheel corrector imitation height15MMGuide wheel corrector imitation height1.5MMFeed mechanism handwheel feed rate per rotation0.01MMThe dividing disc on the handwheel of the feed mechanism provides a feed rate per unit of rotation1.5MMHorizontal feed rapid movement amount (when the handle rotates 120 °)0.015MMCorrector dial feed rate per one revolution285MMThe center line between the grinding wheel and the guide wheel is connected to the height of the bracket surfaceDistance between the center of the grinding wheel and the center of the guide wheel670MMmaximum400MM Hydraulic system working pressure6~7KG/MMHydraulic pump flow rate5 liters per minuteCooling pump flow rate100 liters per minuteLubrication pump flow rate22 liters per minuteMotor PowerGrinding wheel motor18.5 kWGuide wheel motor1.5 kWHydraulic pump motor0.25 kWlubricating motor0.125 kWCooling pump motor0.25 kWoverall dimension2600mm*1850mm*1800mmNet weight of machine toolAbout 6600kgMachine tool accuracyroundness0.002MMCylindricity0.003MMroughness0.32RaMinder-Hightech is sales and service representative in semiconductor and electronic product industry equipment.
