High quanlity CNC rotary table
CHARACTERISTICS:
Rotary table diameter Ø170, Ø210, Ø255.
Motor rear configuration, fully retaining the Y-axis effective stroke
S series is a powerful air brake mechanism
Use hydraulic unit, no oil leakage.
High efficiency, high tooth depth double lead worm drive.
Relationship between braking force and cutting force and efficiency of rotary table
The braking force of the rotary table is a key factor in supporting high-efficiency cutting forces and the highest safety factor must be maintained:
The braking force should be greater than 200% of the cutting force
The efficiency of metal machining cutting forces comes from complex conditions, including:
1.Machining center machine rigidity, spindle speed performance
2.Machining power output and adjustment of machining centers
3.Application of high speed tools
4.safe and stable clamping force
5.Peripheral auxiliary configuration
