Machine-Tool Spindle Drawbar Gripper Grease

SEIVIOCuszlub J391 machine tool spindle drawbars claw greaseIt is a synthetic base oil with excellent heat resistance thickened by a soap thickener, and is refined by adding various additives such as antioxidants and anti-corrosion. It is specially used for four-petal pulling claws (pulling claws), pull rods, disc springs, and clamping cones to solve the working conditions of heavy load, impact, high temperature, cutting fluid erosion and other conditions under tens of thousands of high-frequency tool unclamping and drawbarsing movements of the spindle, maintain stable drawbar force, and prevent the claws from getting stuck, seizing, wearing and rusting.

• Stabilize the drawbar force, keep the friction coefficient stable, and avoid the risk of the tool handle not being clamped tightly and the tool falling due to fluctuations in friction;
• Extreme pressure anti-wear and anti-seize form a solid lubricating protective film under huge contact pressure to prevent fretting wear and sintering of the claw flap and cone surface;
• Strong adhesion and anti-centrifugation, the grease is not easily thrown away by centrifugal force when the spindle rotates at high speed, and adheres to the metal surface for a long time;
• Resistant to erosion by cutting fluids, anti-rust and anti-corrosion, resistant to flushing by emulsions and synthetic cutting fluids, and prevents corrosion of internal parts;
• It is resistant to high temperatures and has a long service life. It is not easy to drain away or oxidize and dry out in the heating environment inside the spindle, reducing the frequency of disassembly and maintenance.
