This model is considered the absolute industry standard in toolmaking, prototype construction, and demanding small-batch production. Thanks to the intuitive WEILER cycle control system, both the simplest turning operations can be performed manually via the traversing handwheels, and complex contours can be programmed highly efficiently without in-depth ISO code knowledge. The machine comes from a clean workshop, has been regularly maintained, and exhibits excellent mechanical accuracy. _____ Technical Data in Detail: Working Area & Capacities: • Distance between centers: 750 mm • Swing over bed: 330 mm • Swing over cross slide: 160 mm • Bed width: 240 mm (massive, heavily ribbed cast iron bed for maximum vibration damping) • Travel of cross slide (X-axis): 180 mm Main Spindle & Drive: • Spindle head / spindle nose: Size 5 (according to DIN 55027 / ISO 702-3) • Spindle bore: 43 mm (usable inner diameter) • Diameter of the spindle in the front bearing: 70 mm • Speed range: 1 – 4,500 rpm (continuously variable via digital inverter) • Drive power (60% / 100% duty cycle): 11 kW / 9 kW • Max. torque at the spindle: 165 Nm (high cutting performance even at low speeds) Feed & Axis Dynamics: • Rapid traverse rate Z-axis (longitudinal): 8 m/min • Rapid traverse rate X-axis (lateral): 4 m/min • Feed rate range: 0.001 – 50 mm/rev • Threading range: 0.1 – 2,000 mm • Feed force (longitudinal axis): 6,000 N Tailstock: • Arbor diameter: 50 mm • Arbor taper: MK 3 (with integrated anti-rotation device) • Arbor travel: Via handwheel with adjustable scale ring and additional longitudinal scale • Clamping: Convenient eccentric clamping on the bed _____ Operating Hours, Control System & Condition: • Switch-on hours (machine under power): 26,492 h • Important commercial note regarding operating time: Based on experience, the actual spindle running time (pure turning under load) in workshop machines is only 30% to 50% of the switch-on time. The actual machining time is therefore only approximately 8,000 to 13,000 hours! • Accuracy: Toolmaker's accuracy according to DIN 8605. • Equipment: Traversing control panel with electronic handwheels, automatic central lubrication of guideways and spindle lead screws, folding chuck guard, coolant system, and complete machine documentation. _____ Inspection & Handling: Iajdpfx Aijvphv Toxew The machine is located at our site in Graz (Styria). It is fully connected and can be inspected and thoroughly tested at any time after prior appointment. A video of the spindle running up and the axis travels can be sent in advance via WhatsApp or email upon request. • Loading: The professional loading by crane/forklift onto your provided truck is included in the price.
