Process coverage
Bottom-hole drilling, internal boring, inner thread milling, chamfering, stepped boring, and end-face milling.
Type III / IV cylinder neck machining machine
Horizontal machining center for Type III and Type IV cylinder neck drilling, boring, chamfering, thread milling, and indexed turning.
Horizontal machining unitBT50 spindle24-tool magazine
Machine format
Horizontal machining center with moving-column unit, dedicated table, self-centering clamps, servo rotary table, tail support, hydraulic station, and centralized lubrication.
Loading and clamping
Manual loading with hydraulic self-centering clamping at the front and rear, plus matched support on the cylinder body side.
Workflow
The part is clamped, machined on one end, indexed 180°, and then machined on the opposite side.

Mechanical highlights
- High-strength cast iron base with stress-relief treatment.
- Linear roller guides and ball-screw transmission on motion axes.
- Servo-driven 180° indexing table for stable turning.
- Wet cutting with independent coolant tank, twin pumps, and chain chip conveyor.
Typical inquiry scenarios
- Composite cylinder production When multiple neck features must be completed on one dedicated platform.
- Large workpiece stability When secure self-centering clamping, tail support, and indexed turning are required.
- Project definition When machine scope, process coverage, and configuration must be confirmed before quotation.
