This is the main body of the milling unit (milling unit, cutter holder). The material is made from high-tensile S50C. After grinding the reference surface, the bearing insertion part is finished with a 5-axis machining center. We provide integrated services from material procurement, processing, unit assembly, to rotational testing and data assurance through 3D measurements.
5-axis machining, coaxiality, perpendicularity within 2 microns, 3D measurement.

Processing Steps:
- Material → M/C → NC lathe → Outer diameter grinding → M/C (4-axis or 5-axis) → 3D measurement (21 degrees)

Processing Precision:
- Perpendicularity of the main spindle to the axial direction: within 0.002
- Coaxiality of the left and right sides of the axis: within 0.002

Design and Manufacturing of Rotating Tool Units:
We design and manufacture rotating tool units based on your requirements, product information, and turret space information. We accept orders for special and custom items that cannot be handled by manufacturers.
- Double-ended rotating tools, 2-axis rotating tools, 3-axis rotating tools, universal support, inclined support, etc.
- High precision type, high-speed rotation type
- Lead time: 2.0M~3.5M, Price: Please inquire.

### Rotating Tool Unit Repair Business:
End-users often use expensive rotating tool units until they break without realizing their deterioration. To assist with regular maintenance, we have launched the "Rotating Tool Repair Business Division."
1. Significant cost advantage compared to new purchases.
2. Extends the lifespan of rotating tools.
3. Quick repair and overhaul.
4. High precision guaranteed through verification of dynamic accuracy, static accuracy, and geometric accuracy.
5. Reduced product defect rates due to high precision.
6. Prevention of economic losses from sudden failures.
