INFORMATION
The latest series from Star Micronics is the SX Series, a versatile, powerful and heavy-duty solution for machining complex mill-turn parts. Combining some of the best features from the SV, ST and SR series, the new SX-38 Type A gives users the opportunity to expand their machining capabilities and maximize productivity.
The Star SX-38 Type B, a 12-axis compact Swiss-style machine with slant-bed construction, maximizes productivity for difficult-to-machine materials up to 42mm diameter. The capability to keep 80 tools resident with high horsepower motors means heavy metal removal rates and flexibility. B-axis surfacing with up to 135 degree travel handles up to 0.5″ diameter tooling.
This high-functioning, large-diameter model – with gang-type and turret-type tool posts – serves the precision machining requirements demanded by the medical, automotive, and aviation industries. The gang-type tool post is equipped with the 4-spindle counter face milling unit with B-axis control function.
BENEFITS
- Standard machining diameter 38mm
- Z1 stroke of 320mm in Swiss mode, 95mm in non-guide bush mode
- Enhanced functionality includes, the gang-type tool post is equipped with the 4-spindle counter face milling unit with B-axis control function *1. Control of turning angels at the range from 0 deg. to 90 deg. and from 0 deg. to -45 deg. is possible.
- In addition to type A, quick-changeable turret-type tool post enabling use of the existing tool units, type B, turret-type tool post with one-position tool drive mechanism is lined up
- The layout of the tool post with slanted bed frame greatly improved setup and maintenance workability
- The 4-spindle counter face milling unit employs the structure for holding the upper and lower ends.
- The hydraulic rotary cylinder installed in the main chucking mechanism secures stable gripping force regardless of variation of workpiece diameters
- The thermal sensors installed on various positions of the machine achieve highly accurate and flexible thermal displacement correction
