CK6140 Flat Bed CNC Lathe Machine Overview

The CK6140 Flat Bed CNC Lathe Machine is a compact precision CNC turning machine designed for small and medium-sized metal workpieces. With a 400 mm swing over bed, 1000 mm distance between centers, 52 mm spindle bore, and 5.5 kW main motor, the CK6140 provides a practical balance of machining capacity, precision, and production efficiency.

The machine features a rigid flat bed structure, precision spindle assembly, vertical 4-station tool post, and GSK CNC control system. FANUC and Siemens CNC systems are available as alternative configurations according to customer requirements.

This flat bed CNC lathe machine is suitable for machining shafts, bushings, sleeves, fittings, pins, bearing components, automotive parts, and other cylindrical mechanical components requiring reliable CNC turning performance.

• 400 mm Swing Over Bed: The 400 mm swing capacity provides suitable clearance for small and medium-sized cylindrical workpieces.
• 1000 mm Distance Between Centers: The 1000 mm center distance allows the machine to handle shafts, sleeves, pins, bushings, and other elongated components.
• 52 mm Spindle Bore: The 52 mm spindle bore provides flexibility for machining suitable bars, shafts, tubes, and hollow components.
• 5.5 kW Main Motor: The main motor provides stable spindle drive performance for general CNC turning and precision machining applications.
• 50–2000 rpm Spindle Speed: The wide spindle speed range supports different turning operations and workpiece materials.
• Vertical 4-Station Tool Post: The standard 4-station tool post provides convenient tool positioning for CNC turning operations, with a 6-station configuration available as an option.
• Multiple CNC Control Options: GSK CNC control is available as standard, while FANUC and Siemens systems can be configured according to customer requirements.
• Automatic Lubrication System: Centralized lubrication supplies lubricant to guideways and moving components to help reduce wear and maintain reliable machine operation.

• Rigid Flat Bed Structure: The cast iron flat bed provides a stable foundation for CNC turning and helps reduce vibration during continuous machining.
• Precision Spindle Assembly: The spindle assembly is designed to provide stable rotation and support accurate machining of shafts, bushings, sleeves, and cylindrical components.
• Compact CNC Turning Capacity: The 400 mm swing and 1000 mm center distance provide a practical configuration for small and medium-sized workpieces.
• 52 mm Spindle Bore: The spindle bore provides suitable clearance for compatible bar stock, shafts, tubes, and hollow workpieces.
• Vertical 4-Station Tool Post: The standard tool post provides convenient tool positioning, with an optional 6-station configuration for additional tooling flexibility.
• Centralized Automatic Lubrication: The lubrication system supplies lubricant to guideways and moving parts to reduce wear and support long-term reliability.
