LIDKÖPINGCL630/660Wide-wheel centerless machine for high-outputprecision grinding

CL630/CL660KMT Precision Grinding is Sweden’s largest machine tool manufacturer.We specialise in the manufacture of precision grinding systems.Our goal is to give you accuracy, efficiency and reliability throughour products, our process knowledge and development,customer support and service. Through close cooperation withend-users, we ensure a correct and profitable solution for you,the customer.The LIDKOPING centerless grinder is designed and manufacturedto meet practically any challenge in precision grinding.The Centerless is the foundation stone of our reputation as aleader in precision grinding technology.Infeed or throughfeed grindingThe CENTERLESS grinding machine offers two main type of grindingoperations, infeed or throughfeed grinding depending onthe shape of the work piece.Grinding spindleMain spindle drive permits constant grinding speed.Grinding wheelis dressed by a servomo¬tor-drivenhydrostatic CNC dresser with fixed diamondor diamond form roller.Regulating wheelis dressed by a servomotor-driven hydrostaticCNC dresserRegulating wheel headstockcan be fed manually, or via a servomotorwith pre-loaded ball screw.Adjustable work blade supportSpindle drivesSiemens main spindle drive is used forgrinding spindle. Servo motors are standardfor regulating wheels.Dressing unit for grindingwheelDressing unit for regulatingwheelRegulating spindleIs servomotor driven via a hypoid gear. Speed range10 rpm to 750 rpm.Spindle drivesBelt and pulleys are used as main spindle drive for the grindingspindle.Cartridge-type spindlesfor grinding and regulating wheel enable quick wheel change.Wheels can be mounted directly on spindles, or on a separatewheel mount.Control systemGraphical user interface provides userfriendlycontrols and Integrated.Program Generator IPG. ControlSystem, Siemens 840D solution line.The SINUMERIK 840D solution line is Grinding gapa distributed, scalable, open and interconnectingcontrol system that offers a wide range of functions.This flexible, universal CNC can be used for up to 31 axes.CamshaftAutomotive - ExternalOuter RingBearing - ExternalShaftAutomotive - External

Fixed work centerwith vertically adjustable workblade support and movablegrinding/regulating wheel headstocks. No adjustment is neededto in- and outfeed devices, to compensate for wheel wear.Hydrostatic grinding wheel headstockwith pre-loaded servomotor-driven ball screw provides feedresolution of 0.1 μm, forwards and backwards.Dual bearing supporton grinding and regulating spindles ensures high stabilityin the grinding gap, essential to high quality grinding.About Key features usKey features that guarantee accuracy, output,life-cycle economy and safety:Fixed work centerHydrostatic grinding wheel headstock –down to 0.1 μm feed resolutionGrinding gap stabilityNo radial forces from spindle drive beltson grinding spindleDual-supported grinding and regulatingspindlesShort cycle timesSafe, easy operationPower transferto grinding spindle is via belt and pulley, utilizing an independentpulley bearing and spline sleeve to eliminate radial tension.About usKMT Precision Grinding develops, markets,manufactures, and installs high-precisiongrinding machines with surrounding equipmentwithin the area of high precision grinding.We market our products under thetrademarks LIDKÖPING and UVA.
