China Mechanical Power Clamping Screw Rods

1. Mechanical power clamping screw rods are integrated as a key component in the box jaws fitted on the chuck or integrated directly into a faceplate or chuck to hold very heavy workpieces on a vertical boring mill, a horizontal lathe, a deep-hole boring machine etc.;
2. Major parts on each mechanical power clamping screw are made of high-strength and high-hardness alloy steel to ensure the power clamping screw a high reliability in clamping jobs;
3. It is easy to operate and can generate a very high clamping force towards the workpiece by driving it manually with a low torque;
4. All dimensions on the mechanical power clamping screw rods, including diameter, length, etc. Can be specified by the customer. These mechanical power clamping screw rods can always be custom made.
