3'', 4'', 6'' Super-Lock Precision C.N.C. Machine Vise 0.0002 Inch

• Features a thrust bearing that increases clamping power by 80%
• Can be mounted upright or sideways. Excellent to use when you have multiple vise setups
• Can not guarantee the exact location of the Keyway Slot. Need Machining the Keyway if they used in pairs.
• Internal refine grinding treatment, smooth use. No jamming, rust and corrosion resistance.
• The surface is quenched, turned, and ground, enabling strong toughness, high tensile strength, and wear resistance. 
• Guide rail surface is a refined ground seamless contact surface. Can be used upright without affecting the accuracy of clamping capacity.
• For CNC milling machines, drilling machines, and precision parts.
• Accurately ground flat vise connects precisely with the machine tool, thus reaching an accuracy requirement of 0.0008" (0.02 /100mm)
• Jaw material: 45# steel
• Body material: ductile cast iron. 
• Wrench material: ductile iron. 

• Workpiece Surface Flatness: 0.02/100mm
