SPINDLE BEARINGS
The spindle is supported by large bearings, preloaded in radial and axial directions, while resisting horizontal and vertical heavy cutting loads. In addition, this feature also keeps rotary tables smooth and accurate rotation at all times.
A test report for 320 series rotary table indicates the spindle supported by bearings preloaded in radial and axial directions provides 2-3 times higher rigidity than those supported by cross-roller bearings.

BRAKING MECHANISM
The braking mechanism is designed with full 360 ° circumference hydraulic clamping. The hydraulic clamping synchronized clamping for the entire table. The clamping area on the entire circumference of the table features maximum rigidity and is ideal for heavy cutting applications. Its clamping force is bigger than that of conventional disk braking systems. Another benefit is that this avoids table deformation and accuracy deterioration that usually occurs on disk braking systems. |
| |
|
The hydraulic clamping mechanism on our rotary table is close to the work table. This special design exhibits higher rigidity and better heavy cutting resistant capability. During cutting, the table deviation is reduced. However, conventional rotary tables with disk only provide less clamping area and longer distance from the cutting position, causing bigger deviation of table. |

BACKLASH ADJUSTMENT WITH DUAL LEAD WORM
FEATURES
The specially designed dual lead worm features full depth gear teeth and greatly reinforced teeth.
MATERIALS
WORM GEAR: Special high tensile aluminum bronze alloy (ALBC3).
WORM: Nickel chrome-molybdenum (SNCM21), normalized and carburized to hardness over HRC 60°. |

TORQUE TRANSFER EFFICIENCY
The matching parts of alloy steel and aluminum bronze reduce friction co-efficiency.
This provides greater transmission efficiency than that of other materials. |
