UL Series
- One-piece flat-bed base coupled with 30degree slant saddle, made of high tensile strength Meehanite casting, heat treated and ground. Hardness may reach HRC 53. All sliding surfaces are coated with Turcite B to maintain feeding and positioning accuracy plus long service life. Chip flushing function is excellent for this structure.
- Large span of high-rigidity box way design, along with high damping coefficient, allows heavy or discontinuous cutting of carbon steel, stainless steel, and aluminum casting without inducing chatter.
- Specialised scraping assembly work and Z-shaped lube-groove design, provides best lubrication for sliding surfaces
- Reinforced headstock structure with symmetrical design balances thermal displacement and reduces spindle errors. Annealed, natural seasoning diminishes internal residual stress for stable material quality and assures long-term machining accuracy.
- Large-diameter, high precision dual-roller bearings and self-alignment angular contact ball bearings support spindle to withstand radial, axial, and combined loading. It is applicable to high-speed fine turning as well as low-speed, heavy-duty turning.
- High-performance, wide range spindle motor powered by 20 hp offers full-scale power output at speed range of 750-6000rpm. In addition, 190Nm high-torque accelation makes it the most powerful lathe at this level.
- Large-size precision curve coupling with roller-cam mechanism and hydraulic actuator provide accurate positioning for indexing. Fast bi-directional index selects tools at 0.3 seconds for adjacent tool, and 1.5 seconds for opposite tool.
- Pre-loaded double-nut ballscrews featuring high rigidity, alleviate backlash more effectively.
- Square box sideways on X/Y axes have high stiffness, large contact areas and excellent damping effects. They are the best design to sustain heavyduty as well as segmented cuttings.
Parts Catcher
Upon completion of turning cycle, catcher automatically receives workpiece, then conveys it out the gate to the workpiece collection box, saves more time if fitted with automatic bar feeder.
Tool Setter
Eliminating downtime for tool inspection and compensation, this manual setter measures and offsets tool wear to maintain 5µ m repeatability accuracy.
