SK Powerful collet chuck tool holder

SK Powerful Collet Chuck TOOL HOLDER is suitable for milling machine, heavy cutting and precision cutting. Powerful chuck Tool Holder is a common tool holder in cutting process. It is used to clamp straight shank cutters such as milling cutters and reamers. The clamping deformation of clamping spring is small. The design of inner hole groove and uniform elastic deformation can ensure excellent precision. Special needle bearing arrangement design, low locking resistance, high clamping force, can produce 280 KGM clamping force.

SK Tool Holder SK Power Chuck, Straight Shank Collet clamping tool for various sizes of cylindrical shank, high speed and high precision machining ,The locking principle of powerful chuck tool holder Similar to the principle of ratchet bearing, the needle rolling is thick in one direction on the conical surface and thin in the opposite direction, instead of rolling on the contour surface. That is to say, the clearance is smaller in one direction, locking, and the clearance is larger and loosening in the other direction. When the locking sleeve rotates clockwise, it drives the cage and the needle to rotate. When the needle falls into the groove of 0.8 on the chuck body, the cage tilts due to the guiding effect, and continues to rotate the groove of 0.8 to make the needle move upward so as to drive the cage to move together, forming a spiral upward motion. Because of the taper effect, the chuck body deforms inward. Form locking force. Release the helix downward counterclockwise. The diameter tolerance of clamping tool holder is h6. The clamping force is larger and the clamping precision is better. Different cylinder clamps can be replaced to clamp milling cutters and reamers with different shank diameters.
