Gap Bed Engine Lathe
Use
The Gap Bed Engine Lathe series (CW61125, CW61140, CW61160) redefines industrial machining efficiency with its robust construction, versatile capabilities, and precision engineering. Designed for heavy-duty turning operations, these lathes excel in handling large-diameter workpieces while maintaining exceptional rigidity and accuracy. Ideal for industries requiring high-volume production or complex part fabrication, our gap bed lathes deliver unmatched performance across automotive, aerospace, energy, and general machinery sectors.
Features
Superior Rigidity & Stability
Reinforced Gap Bed Design: Allows machining of oversized flanged or irregularly shaped components by temporarily removing a bed section.
Wide Bed Guideways (755mm): High-grade cast iron construction with induction-hardened surfaces ensures vibration damping and long-term durability.
High-Precision Spindle System
Ø130mm Spindle Bore: Accommodates large bar stock and reduces setup time for tubular workpieces.
1:20/140 Taper: Secures heavy-duty chucks and fixtures with zero slippage.
21-Speed Gearbox (3.15–315 RPM): Optimized torque delivery for both fine finishing and aggressive roughing.
Advanced Threading & Feed Control
56 Feed Variants: Achieve micro-level precision with longitudinal feeds (0.1–12 mm/rev) and cross feeds (0.05–6 mm/rev).
Multi-Thread Compatibility: Cut metric, imperial, module, and diametral pitch threads in a single setup.
User-Centric Design
4,000 mm/min Rapid Traverse: Minimize non-cutting time with high-speed carriage movement.
Modular Tailstock: 300mm quill stroke with Morse No.6 taper for flexible support configurations.
Scalable Configurations
Workpiece Length: Choose from 1.5m to 10m bed lengths to match production needs.
Custom Tooling: Compatible with hydraulic, pneumatic, or CNC-controlled tool posts.
