Double Spindle Center Drive Lathe
HIGHLIGHT
- Simultaneous machining at both ends: Both spindles are driven simultaneously, with tool holders at both ends cutting synchronously. All processes, including external turning, end facing, internal drilling, and chamfering, are completed in a single setup, halving the cycle time.
- Thermally symmetrical high-rigidity structure: A 45° slant bed + box-type spindle box layout, with coaxially opposed dual spindles, ensures closed-loop cancellation of cutting forces, maintaining micron-level precision even during long-term operation.
- Dual-channel CNC system: Independently controls the left/right spindle speed and feed, allowing for synchronous or differentiated machining. Supports turning-milling-drilling composite cycles; changeovers only require program reloading.

Features
Compared to conventional CNC machines, the dual-spindle CNC lathe is engineered with two independent control systems, a central spindle, and dual Z and X axes. This configuration enables simultaneous machining on both ends of the rotating workpiece, improving processing efficiency by 70% to 200%.
Equipped with high-performance roller screw guideways from Japan’s top-tier brand THK, the system ensures superior positioning accuracy during high-speed operation. Repeatability is consistently maintained within ±0.008mm over 300mm, combining speed with lasting precision.
Designed with an inclined Z-axis drag plate, the structure effectively minimizes thermal deformation during high-speed, heavy-load machining. It excels in large-margin turning, maintaining dimensional accuracy even under intense dynamic conditions.
Built on an HT300 one-piece cast iron bed, the lathe delivers exceptional rigidity and structural stability. With tensile strength exceeding 300 MPa, and a robust integrated turret design, it offers extended tool life and the capability to handle demanding machining tasks.
All critical components are sourced from renowned global and domestic manufacturers, including NACHI, THK, Schneider, Baibu Precision, and Japan’s Yuken. This elite supply chain ensures stable performance and long-term reliability in daily operation.
Every ZTZ machine is delivered with a unique four-dimensional mechanical fingerprint, capturing key metrics such as positioning accuracy, torque, vibration levels, and temperature rise. This integrated quality monitoring system removes guesswork from machine commissioning, ensuring consistency and simplifying setup.
