Inparticular, this system is suitable for small workpieces that cannot be held bymagnetic chucks. ※1■Significantly improved grinding accuracy!　Highly precise grinding in the order of micron achievable!●The bonding film that aff ects grinding accuracy has been made thinner by using“workpiece fixing agent Enewly developed by KANETEC to realize a grindingaccuracy in the order of micron. Also it has been made possible to secureworkpieces at low temperature close to room temperature and a diff erence intemperature during securing and releasing workpieces has been reduced tominimize thermal impact on workpieces. Wet operations are allowed. ※2●Adverse influence on accuracy due to warping of workpieces, which isunavoidable when mechanical clamps are used, has been eliminated.●The work face is made of iron in consideration of accuracy stability and wearresistance. The work face accuracy can be recovered by regrinding the work face.■Easy installationThe main unit can be installed on a machine by use of T-slots. Also since itsmounting face is made of iron, it can easily be mounted on your magnetic chuck.■Compact controllerThe controller measures as small as 450 mm wide ÁE450 mm deep ÁE845 mmhigh and can be installed in any place. It comes with a remote operation box.※1 Both magnetic and nonmagnetic materials can be secured. In particular, this systemis suitable for grinding of cemented carbide, ceramic, stainless steel and aluminum.However, it cannot be used with the following workpieces in some cases:・Workpieces having abrasive-like surface (e.g. plaster)・Workpieces warped largely (more than 0.5 mm)・ Thin (less than 1.0 mm) workpieces such as stainless steel that tend to bedistorted by grinding heat・Some resins such as Teflon※2 The wax used with this system is susceptible to impact and therefore cannotbe used for cutting as a rule. In dry operations, the temperature ofworkpieces rises to melt the wax and therefore, it cannot be used.A system to enable a wide range of precision grinding of anymaterials; nonferrous, resin or ceramic.Model VIonlptaugte VoltagOeutpuCt urrent MassPRC-220B 3-phase 200 VAC, 50/60 Hz 200 VAC 20A 120kg/264 lb�E�mm�E�En�E�］■Two types of fixing agent; standard type and lowviscositytype (high precision type) available!Standard typeLow-viscosity typeSUS304 A5056 Ceramic MC nylon PolypropyleneFixing power (by materials)Material14121086420�E�Eg/cm2�E�Fixing powerStandard typeMelting temperature 65℃The fi xing power is high, but its film thickness is 5 to 10 μm.Low-viscosity type (High precision type)Melting temperature 45℃The fi xing power is low, but its film thickness is only 1 to 2 μm, whichmakes this type suitable for finishing operations.
