CK61140 Flat Bed CNC Lathe Machine Overview

The CK61140 Flat Bed CNC Lathe Machine is a powerful heavy-duty CNC turning machine designed for large-diameter and long industrial workpieces. With a 1400 mm swing over bed, 3000 mm distance between centers, 130 mm spindle bore, and 22 kW main motor, the CK61140 provides substantial machining capacity for demanding turning applications.

The machine features a rigid flat bed structure, large-capacity spindle, 1000 mm chuck, and 4-station electric tool post. GSK CNC control is available as the standard configuration, with FANUC and Siemens systems available according to customer requirements.

This flat bed CNC lathe machine is suitable for machining large shafts, rollers, cylinders, flanges, transmission components, and other heavy mechanical parts requiring high rigidity, strong cutting capability, and stable CNC turning performance.

• 1400 mm Swing Over Bed: The large swing capacity provides substantial clearance for oversized shafts, rollers, cylinders, flanges, and other large rotating components.
• 3000 mm Distance Between Centers: The long center distance provides machining capacity for large and elongated industrial workpieces.
• 130 mm Spindle Bore: The large spindle bore allows suitable bars, shafts, pipes, and tubular components to pass through the spindle.
• 22 kW Main Motor: The high-power spindle motor provides strong cutting capability for demanding heavy-duty turning operations.
• 1000 mm Chuck: The large chuck provides substantial workholding capacity for oversized industrial components.
• 4-Station Electric Tool Post: The standard electric tool post provides convenient CNC tool positioning, while 6-station and 8-station configurations are available as options.
• Multiple CNC Control Options: GSK CNC control is available as standard, with FANUC and Siemens CNC systems available according to customer requirements.
• Centralized Automatic Lubrication: The centralized lubrication system supplies lubricant to moving components to help reduce wear and maintain long-term machine performance.

• Extra Heavy-Duty Flat Bed Structure: The rigid flat bed structure is designed for large-diameter and heavy-component machining while helping absorb vibration during heavy cutting.
• Large Swing Machining Capability: With a maximum 1400 mm swing over bed, the machine provides substantial capacity for oversized rotating components.
• High-Power Spindle Drive: The 22 kW spindle motor and 130 mm spindle bore provide strong cutting capability for demanding turning applications.
• Large Workpiece Support: The 1000 mm chuck and heavy-duty machine structure provide stable clamping and machining support for large industrial components.
• Precision CNC Control: GSK CNC control is available as standard, with FANUC and Siemens systems available for customers requiring alternative CNC configurations.
• Flexible Tool Post Configuration: The standard 4-station electric tool post can be upgraded to 6-station or 8-station configurations according to machining requirements.
• Automatic Lubrication System: The centralized lubrication system continuously supplies lubricant to moving components to reduce wear and support long-term machine performance.
