Features

2-axis CNC axes: X-axis--radial feed; Z-axis--vertical feed. X-axis and Z-axis can work independently or coordinately to produce tapered and crowning gears.
Climb, conventional, climb-conventional and conventional-climb hobbing methods are available.
High precision worm gearings are used for the worktable indexing system.
Double enveloping worm gearing is used for the worktable indexing system equipped with a clearance-eliminating mechanism.
High precision worm gearing is used for the worktable indexing system.
Precision ball screws are used for CNC axes. High performance encoders are used for feedback inspecting for the movement of CNC axes to ensure high moving and positioning accuracy.
