The CW6180 Extra-Long Conventional Lathe is a heavy-duty horizontal turning machine designed for precision machining of large-diameter and extended metal workpieces. Featuring an 800 mm swing over bed and a 600 mm wide induction-hardened bedway, it handles center distances from 1,500 mm to 6,000 mm. It performs external and internal turning, taper facing, grooving, drilling, and multi-pitch thread cutting across steel, cast iron, and non-ferrous metals.

High-Rigidity Construction & Precision

Hardened Cast Iron Bed
Built with a 600 mm wide high-grade cast iron bed featuring induction-hardened guideways and wear-resistant saddle bands, ensuring long-term alignment stability under heavy cutting loads.

3-Support Precision Spindle
The spindle utilizes a robust 3-support structure driven by an 11 kW main motor, maintaining a roundness error within 0.01 mm and cylindricity within 0.04 mm over a 300 mm test length.

Machining Capabilities

Comprehensive Threading
Integrated gearbox enables immediate cutting of 50 Metric (1–240 mm), 26 Inch (14–1 TPI), 53 Module (0.5–120), and 24 Diametral Pitch (28–1 DP) threads without manual gear replacement.

Shaft Support System
Machine models with turning lengths of 2,000 mm and above include both a steady rest and a follow rest as standard items to prevent workpiece deflection during long-shaft processing.

Target Applications of CW6180 Extra-Long Conventional Lathe

Power Transmission Shafts
Machining long drive axles, hydraulic cylinder rods, and turbine shafts up to 6 meters in length.

Heavy Mechanical Components
Facing, grooving, and turning large flanges, sleeves, and rollers utilizing the 800 mm swing clearance.

Piping & Oilfield Equipment
Threading and end-facing oversized tubes and drill pipes using the optional 140 mm spindle bore.

Configuration & Options

Standard Equipment:
400 mm 3-jaw manual chuck, spindle center, steady rest and follow rest (for lengths 2 m and above), cooling system, working light, and foundation bolts.

Optional Upgrades:
140 mm extra-large spindle bore, 4-jaw independent chucks, oversized rests, and digital readout (DRO) systems.

FAQ

Q: What spindle bore size should I select for long pipe machining?

A: The standard 100 mm bore handles most solid shafts. For feeding large tubes or drill pipes through the headstock, the optional 140 mm spindle bore is recommended.

Q: Are steady rests included with extended bed models?

A: Yes, all configurations with center distances of 2,000 mm to 6,000 mm include a steady rest and follow rest as standard equipment.

Q: What materials can this lathe process efficiently?

A: The machine is built to cut carbon steel, alloy steel, cast iron, and non-ferrous metals across both roughing and finishing operations.

Q: What precision standards are verified before shipment?

A: Factory inspection certificates verify roundness error of no more than 0.01 mm and cylindricity error of no more than 0.04 mm across a 300 mm measuring length.
