Machine-Tool Spindle Drawbar Disc-Spring Grease

SEIVIOCuszlub Z113 machine tool spindle drawbars bar disc springs grease It is made by thickening a synthetic base oil with excellent heat resistance using a soap thickener, and adding various additives such as antioxidant and anti-corrosion.。‌It is a special heavy-duty anti-fretting synthetic grease specially designed for the disc springs group, tie rod and guide sleeve in the spindle drawbarsing mechanism of CNC machine tools. It is used to solve the special lubrication needs of this part under extreme working conditions.

• Ultra-low friction and anti-stick-slip, the friction coefficient is stable at 0.04~0.07, forming a solid-liquid composite lubricating film to eliminate the "stick-slip" phenomenon between spring pieces;
• Stable drawbar force: The friction coefficient between the discs is controlled to be stable to prevent the pulling force from being too large or small, and to prevent the tool handle from being clamped tightly and the tool from falling off;
• Resistant to cutting fluid erosion, waterproof and rust-proof, and resistant to workshop emulsion intrusion and corrosion of disc springs;
• There will be no oil separation or softening after repeated extrusion and shearing, the lubricating structure will be stable for a long time, and the broach unclamping action torque will be stable without jamming;
• The disc spring opens and closes repeatedly, causing fretting friction between the discs; the grease forms a strong extreme pressure oil film to avoid disc strain and pitting corrosion;
• Suppresses fretting corrosion under high contact stress above 200MPa. After 1 million tool changing cycles, the spring fatigue fracture rate is reduced by more than 80%, and the drawbar force attenuation is less than 5%.
