Spark Lathe 61140

Superior Rigidity for Heavy-Duty Cutting

The bed, headstock and saddle are made of high-grade cast iron with aging treatment to eliminate internal stress. The thickened bed wall and reinforced guide rail structure ensure minimal deformation during heavy-duty machining, supporting stable cutting of large workpieces.

High Machining Precision & Consistency

The spindle is equipped with high-precision double-row cylindrical roller bearings and angular contact ball bearings, reducing radial and axial runout. The guide rails adopt quenching and grinding process (surface hardness HRC50-55), ensuring long-term positioning accuracy and consistent machining quality.

Wide Adaptability to Workpieces

With large swing diameter (1400mm) and multiple optional processing lengths, it can handle large-scale shaft parts, disc parts and sleeve parts in industries like heavy machinery, wind power and petroleum. It is compatible with materials such as carbon steel, alloy steel and cast iron.

Efficient & Reliable Operation

The transmission system adopts multi-stage gear transmission with high-quality gears (carburizing and quenching treatment), ensuring smooth power transmission and low noise. The electric control system uses well-known brand components, reducing failure rate and ensuring continuous production.
