• Very low friction, no friction at positioning • Movement of 0.1 micro-m possible • No reversal backlash of friction force • No slip-stick effect at slow motion • Zero wear because there is no contact when operating • No precision or stiffness loss, even under full-load machining and oscillating motion • No friction variation caused by ball reversing • Better damping, resulting in better workpiece finish, longer tool life, and larger cutting volume • No vibration, which is caused when reversing rolling systems • Not sensitive to chips and other debris • Extremely straight movement possible
Technical Features of Hydrostatic Slides
• High precision and extremely parallel horizontal pocket gaps – gaps at the keepers stay parallel even when bending forces are applied • No deformation caused by screws in the slide or guideway • Low production costs because no rails are necessary and no parallel grinding with small tolerances is required • Ideal for horizontal applications, where machining and acceleration forces are lower than the weight forces on the pockets • Ideal for horizontal and vertical slides with high forces and torque load • Very effective for cylindrical grinders, fl at grinders, measuring machines, and ultra-precision machines • The side stiffness increases with increased force on the V-pockets • Hydrostatic guideways can compensate for forces resulting from weight, machining and acceleration. In addition, high speed operation as well as tight stiffness and damping requirements are obtainable
