VACUUM CHUCK Vacuum system required additionally [Application] Chucks to hold workpieces by utilizing atmospheric pressure. Nonferrous and nonmagnetic materials can be held and machined. These chucks are suitable for grinding and cutting plastics and grinding aluminum, brass, stainless steel, ceramic and glass. [Features] •The suction holes on the chuck work face can be arranged to set an effective holding area according to shapes of workpieces by combined adjustment of thread valves and valves. •The suction holes have cross grooves to expand the acting area. Thus, fewer thread valves are used to improve the work efficiency. •The chuck work face is made of iron to allow self-grinding to recover parallelism. •Since the chuck work face is made of iron, magnetic devices such as workpiece stoppers can be utilized. •A special suction hole layout adapter can be installed according to workpieces and work procedures. •These chucks can be mounted on magnetic chucks. •Since no heat source or moving parts are used inside the chucks, highly precise machining is ensured. ■KVR-D (Thread valve type) •An effective holding area can be set according to shapes of workpieces by combined adjustment of thread valves and valves. •Since suction grooves of cross shape are provided on the holding face, the number of thread valves has been reduced to enhance the work efficiency. ■KVR-H (Small hole type) •Holes of 04 are provided on the holding face at 8-mm pitches. <Precautions for use> The vacuum chuck is of such construction that the inside of the chuck is evacuated by a vacuum pump to reduce the internal pressure and a workpiece is held by atmospheric pressure. Therefore, the holding power is determined by a difference between the internal pressure and atmospheric pressure and the holding area. Due to physical restrictions, a difference in pressure that can be obtained by a pump is about 80 kPa (600 mmHg) in consideration of the upper limit of available evacuation efficiency. Since the same holding power as about 80 kPa (0.8 kgf/cm2) can be obtained, if the holding area of a workpiece is 100 cm2, it is held by a holding power of about 800 N (80 kgf). Note, however, that if the holding face of workpieces is rough or distorted, even if slightly, atmospheric pressure leak occurs to decrease the holding power significantly. For such workpieces, some leak preventing measures must be taken. Workpieces could be deformed by heat generated during machining depending on materials and thickness of workpieces. Pay attention to machining methods. In particular, thin stainless steel sheets deform due to machining heat largely and are difficult to hold.
