Q: Is the spindle configuration suitable for heavy-duty drilling and large-diameter boring operations?

A: Yes. The headstock is powered by a 22 kW continuous-duty industrial motor driving 21 forward speed steps. For deep boring of heavy mining couplers and cylinder tubes, the spindle can be dropped into its lower gear ranges (down to 3.15 rpm), multiplying mechanical torque to sustain large chip loads without stalling. The Metric 140 mm front taper and the 130 mm spindle through-hole further allow the integration of heavy boring bars or the pass-through of long structural shafting.

Q: What specific capabilities does this lathe provide for cutting heavy-pitch threads found on mining machinery?

A: Mining machinery relies on heavy, coarse thread profiles to handle extreme operational stresses. The quick-change gearbox of the CW61160 allows operator-direct cutting of large-scale threads without manual gear swapping. It executes Module threads up to 60 mm and Metric pitches up to 120 mm (along with heavy Inch and DP pitches). This internal feed range allows the direct cutting of large screw leads, internal nut threads, and custom worm gear blanks on-site.

Q: What workpiece dimensions can be accommodated over the bed versus over the cross-slide carriage?

A: For large disc or plate components, such as heavy slurry pump impellers, rock crusher flywheels, or large pipe flanges, the machine allows a maximum clearance diameter of 1,600 mm over the bed. For long shaft turning operations—such as heavy excavator axles or industrial rollers—the maximum allowable clearance diameter is 1,250 mm over the moving cross-slide carriage, with a total effective machining length up to 12,000 mm along the bed ways.
