verticalfor valves and flangesfor shaft machining

Overview
The CKM51 Series CNC vertical lathe-grinding compound machine integrates turning and grinding in a single unit to increase machining throughput, reduce setups and improve dimensional accuracy. It is equipped with dual CNC tool holders for combined turning and grinding operations, and an electric spindle grinding head with water cooling for stable high-speed, low-noise performance. Typical target sectors include automotive, aerospace, energy and heavy machinery.

Model Details

• Maximum turning diameter: 2600 mm
• Maximum workpiece height: 1400 / 1600 mm (variants)
• Maximum workpiece weight: 12 t

Key Features

• Dual Tool Holders: Combined turning and grinding tools in one setup allow sequential or simultaneous operations to reduce cycle time and index changes.
• Electric Spindle Grinding Head: Water-cooled electric spindle provides stable high-speed rotation with reduced acoustic emission.
• High-Precision Bearings: Main shaft uses adjustable radial-clearance double-row short cylindrical roller bearings for radial positioning and high-precision large thrust bearings for axial guidance.
• Symmetrical Workbench Structure: Balanced construction to enhance rigidity and repeatability during heavy cutting and grinding.
• Smooth Crossbeam Lifting: Crossbeam raised/lowered by a double-screw system to improve lifting smoothness and positioning accuracy.

Recommended Configurations

• Spindle System: High-precision spindles, spindle motors and active cooling; adjustable grinding-head spindle adjustment system.
• Feed and Worktable System: High-precision servo drives, ball screws, linear guides; electric worktable lifting and feed control with magnetic table or mechanical clamping options.
• Cooling and Chip Removal: Coolant circulation and high-efficiency filtration, automatic chip conveyors and collection tanks.
• Electrical & Automation: CNC control and PLC, HMI, automatic dressing control, integrated loading/unloading and clamping devices.
• Grinding Wheel & Head System: Electric grinding-wheel adjustment and dressing units; adjustable grinding head (horizontal/vertical) and wheel balancing.
• Precision Positioning & Vibration Suppression: Laser/optical measurement, displacement sensors, active vibration suppression and damping systems.
• Safety & Lubrication: Protective covers, safety doors, E-stop and automatic centralized lubrication and filtration.
• Cutting Tools & Accessories: Dressing tools, workholding fixtures and accessories.

Application Case

• Client: Valve manufacturer (Italy)
• Use case: Machining high-precision valve components
• Setup: CKM51 Series with dual CNC tool holders, electric spindle grinding head and servo motor control
• Results: Combined turning and grinding in one setup reduced total production time and maintained tight tolerances (example ±0.01 mm for complex valve parts); production efficiency increased by ~30% in the case study.
• Client feedback: Improved production flow and reduced setup time due to integrated turning/grinding capability.

Additional Notes

• Designed for large, high-precision workpieces such as shafts, discs and flanges; some models/configurations can process diameters up to 5000 mm and workpiece weights up to 15 t (FAQ reference).
• Standard and customized options available to meet specific production requirements.
