Precision Worm / Worm Gear
Worm gear adopts a double-lead design with high transmission efficiency. The worm gear and worm wheel are made of high-grade materials and are precision-machined, the backlash is small and the wear resistance is excellent, which ensures high precision positioning of the rotary table.
Index Accuracy
The division accuracy of the rotary table can reach within 15 seconds. The usually index accuracy is within 20 seconds. The repeat index accuracy is within 4 seconds. Multi-disc disk brake, large size piston, triple friction surfaces.
Pneumatic Brake
Pneumatic brake models: 125,170, 210, 250.
Hydraulic Drum Type Brake
Hydraulic drum type brake Models: 255, 320, 400, The hydraulic drum type brakes have greater braking force than pneumatic brakes, and can avoid slipping and deformation.
Characteristics of Three-piece Coupling
• The index accuracy can reach ±4 seconds.
• Repeated indexing accuracy can reach ±1 second.
• The tooth contact rate reaches 90%.
