Product Description
Application
Independently developed models that can balance mold processing and parts processing; three-axis roller linear guides with high rigidity, high reliability and high torque.
Machine Features
- Stable and sturdy ultra-wide base.
- Bearing covers ground on a dedicated grinder, effectively improving the dynamic response of the machine.
- Three-axis P-grade roller linear guideways.
- Pre-stretched tail-end design of the three-axis screws, reducing thermal elongation (8 mm pitch available for precision mold machining).
- Z-axis can be equipped with a nitrogen balance cylinder to improve Z-axis response.
- Triangular rib layout of the column for a more stable structure and better rigidity.
- Standard BT40-150-12000 short-nose spindle; optional 15000 rpm / HSK-A63 spindle.
Optional Accessories
- 4th-axis rotary worktable
- 5-axis turntable
- Automatic tool length measurement system (tool setter)
- Probe
- Grating ruler
- Automatic tool changing system (disc tool magazine)
- Chip conveyor
