Rigidity where it matters most.

Rigidity where it matters most.

A dual-bearing rotary head eliminates flex and vibration under heavy cutting loads. A harmonic reducer and high-torque Japanese motor deliver smooth rotation at 300°/sec — zero backlash, sub-arc-second angular resolution. The A-axis is aligned to the machine's linear axes. Kinematic accuracy holds across the full range of motion.

Advanced Rotary Head Design for Maximum Performance

Advanced Rotary Head Design for Maximum Performance

The machine features a newly engineered rotary head with a dual-bearing support structure, delivering exceptional rigidity and eliminating vibration—even under extreme cutting loads. This robust design ensures stable and precise machining, even during the most demanding operations. To maintain this performance, the rotary axis (A-axis) is precisely aligned.

FEATURE / WORKHOLDING

1-micron pallet accuracy.

The Mira J9 supports traditional workholding and an integrated Quick-Release System (QRS). A compact mini pallet installs and removes in seconds. Positional repeatability: within 1 micron. Workpieces mount via standard vice or direct screw attachment. Custom pallets available on request.

15 tools. Zero interruption.
FEATURE / TOOL CHANGER

15 tools. Zero interruption.

The Mira J9 carries 15 tools in an integrated automatic changer. Tool changes trigger via standard M6 command, from the control panel, or directly from inside the work area. Each change is followed by automatic tool height measurement — LED-confirmed, referenced before every cut. A chip-resistant cover shields the magazine during machining and lifts automatically on change. Built for unattended operation.
