Feed System
Servo motor connects flexibility coupling arrangement with ball guide straightly to reduce the machinery transmission clearance and eliminate the additional dynamic consumption caused by assembly precision errors.
Spindle
The spindle motor passes a special high-speed arc circular tooth-belt.
With the connection of belt pulley, it completes the main drive system to reduce the skidding phenomenon of belts. The motor speed is much more stable than transmission. In order to ensure the largest axial rigidity, radial rigidity, and machining precision, spindles adopt high-precision NSK P4 class bevel ball bearings to get the maximized span configuration according to the calculation and analyses. Standard speed of spindle is up to 8, 000 rpm, and optional speed is 12, 000 rpm or 15, 000 rpm.
The turret tool
The turret tool capacity is only 12 sets, tool change time of 2.5 seconds, automatic tool change patterns for the arm type, the max. Tool length for 200 mm, the max tool diameter 120 ø (fool tool state) mm, the max. Tool weight 3kg.
High-precision ball screw
High-precision ball screw machine adopts a C3 abrasive class ball screw of high-precision. There are bevel ball bearings (3 for one group) and pre-draw double-nut caps on both sides of ball screw to reduce accumulated heat error.
Fourth-axis (rotary worktable) (optional)
Equipped with the fourth axis rotary worktable, the fourth axis can do polyhedral processing and reduce non-processing time for loading and unloading.
With worm and wormwheel transimission, it has high precise positioning, though after the long time use, it can still maintain high accuracy.
Spindle rotating part employs high-precision bearings to ensure stability of the running centre.
Minimum split angel is precise and commonly used in the spiral cutting and sophisticated aerospace industry.
