Highlights

Highlights

Six core design highlights

🔒
01

Sleeve-Locked Bearings

Replacing traditional nut-locking with sleeve fixation — dramatically improved precision consistency and operational stability.

02

Ceramic Rolling Elements

Standard ceramic rolling element bearings — wear-resistant, heat-resistant, longer life, smoother high-speed operation.

💧
03

Built-in Ring Spray

4 built-in ring sprays standard — uniform and efficient cooling, longer tool life, better surface finish.

🔧
04

Long-Life Tool Clamping

Rectangular spring clamping system with 1M+ clamping cycles — significantly lower maintenance cost.

🌡️
05

Low Temperature Rise

Spindle temperature rise ≤15°C, stable accuracy over long runs.

📐
06

G0.4 Balance Grade

Precision balance grade ensures smooth high-speed operation and minimal vibration.
