Advantages: WAVE Slits prevent from getting chips into the guiding bore Extended guiding up to 40mm depenting on guide bush type Ultra Precise High scratch-free surface on the turning parts Very low coefficient of friction, thus ensuring very good sliding properties Very good for Material with worse sliding properties like TITANIUM Shape consistency and stability is guaranteed by this Alloy Concentricity accuracy is the same as what the user is used to by a guide bush This Alloy is not heat sensitive and non-abrasive Prevents cold shut and friction between Material and guide bush
