Deep Hole Drill Machine for Auto Parts
- Introduced 4 spindle design.
- Introduced counter-rotary and single rotation in term of drilling requirement.
- Fits for drilling of shaft parts. Typical parts like steering shaft, motor spindle of auto air-conditioner, auto connection rod, auto rocker arm, etc.
- Mainly to drill concentric deep hole, also capable for drilling eccentric hole, super deep hole, thin-walled hole and slant hole.
Clamping & Positioning
Clamping and positioning is by chamfer or center hole.
(Special tooling when single rotary version.)
Counter-rotation of drilling spindle and workpiece.
(Single rotary design is also available.)
