Product Features
The design maximizes the internal machining space, avoiding interference between the cutting tool and the sheet metal, making the space more flexible during workpiece machining, and significantly reducing the chance of collision between the cutting tool and the machine tool.
Axial trackTo ensure that the machine tool can maintain its precision and quality even when processing at high speeds, this machine tool uses a Rexroth roller guide system, which has high rigidity close to that of a hardened rail and the advantages of rapid movement of a linear guide.
High-rigidity power turret
The new BMT system features an ultra-high rigidity power turret, with the tool holder secured by four fixing bolts and a locating key, ensuring relatively stable tool cutting operation. Furthermore, the use of a larger diameter crank clutch ensures tool rigidity and accuracy during machining.

High-precision built-in spindle
- Both the main and secondary spindles can be paired with a built-in spindle.
- Using a built-in spindle reduces vibration caused by belt rotation.
- When the spindle rotates, it can achieve lower inertia and faster acceleration and deceleration response.
- The spindle is equipped with standard oil cooling to reduce thermal displacement.
spindle through hole diameter
The high-speed and high-precision spindle design features a high-precision angular contact ball bearing at the front end and a single-row roller bearing at the rear end, ensuring optimal operation and cutting accuracy over extended periods.

- The 8" spindle design has a spindle through-hole diameter of 77mm, allowing bars with a diameter of up to 65mm to pass through.
- The 10" spindle design has a spindle through-hole diameter of 88mm, allowing bars with a diameter of up to 77mm to pass through.
