How does the vertical structure of this series improve machining precision compared to horizontal lathes?

The vertical arrangement eliminates roundness and profile errors caused by workpiece weight and gravity during horizontal clamping. The gravity of the workpiece naturally aligns and fits it closely against the fixture, ensuring higher positioning accuracy, superior roundness, and consistent repeat precision.

What structural features ensure heavy-duty cutting stability and long-term accuracy retention?

The machine utilizes an integrated box-type bed made of high-grade Meehanite precision castings subjected to secondary annealing to eliminate internal stresses. Heavy-duty linear roller guideways, P3-class pre-tensioned ball screws with direct-coupling drives, and Z-axis counterweight compensation ensure exceptional rigidity, superior vibration damping, and long-term dimensional stability.

What tool turret options and specifications does this machine series support?

Turret Types: Hydraulic horizontal turret (standard), vertical turret (for internal bore machining with minimal interference), and BMT live tool turret. Capacity Specs: Accommodates tool shanks and boring holders. Live tool turrets (BMT65/BMT75) support high-rigidity drilling, tapping (up to M27), and milling.

How are thermal growth and spindle thermal deformation managed during continuous operation?

The main spindle uses imported double-row short cylindrical roller bearings designed to absorb heavy axial/radial loads with minimal friction. Additionally, an optional hollow water-cooled ball screw system actively circulates coolant through the screw core, drastically minimizing thermal elongation and maintaining consistent positioning accuracy throughout extended production runs.
