1. Product Overview

The CK6150 Flat Bed CNC Lathe is a medium-sized metal cutting machine featuring high rigidity, high precision, and excellent stability. Adopting the classic “Single V + Flat” bed guideway structure and a three-gear stepless speed change spindle system, it easily handles various complex conditions from roughing to finishing. With a maximum swing over bed of Φ500mm and customizable processing lengths (500-3000mm), it is an ideal production equipment for machinery manufacturing, automotive parts, hydraulic & pneumatic components, and general hardware processing industries.

3. Core Features and Advantages

1. High-Rigidity Bed and Precision Guideways
Made of high-quality cast iron with a “Single V + Flat” guideway structure. The guideways are super-audio frequency hardened and precision-ground, providing strong load-bearing capacity and excellent vibration resistance for stable precision under long-term heavy cutting.

2. High-Precision Ball Screws and Guideways
The X and Z axes are equipped with high-precision ball screws and wear-resistant guideways, ensuring smooth feed movement, minimal friction, and excellent positioning accuracy. This combination significantly reduces backlash and guarantees stable, precise machining during continuous operation.

3. Powerful Spindle System
Equipped with a 7.5kW main motor, offering a wide speed range of 50-1800rpm (three-gear speed change, stepless within gears). The spindle bore options include Φ82, Φ105, or Φ130mm to meet the processing needs of different bar sizes.

4. Excellent Machining Accuracy
Positioning accuracy reaches up to ±0.005mm, machining accuracy achieves IT6-IT7, and surface roughness is as low as Ra1.6. Combined with high-precision ball screws, it ensures excellent repeat positioning accuracy.

5. Efficient Tool Post and Tailstock
Standard equipped with an electric 4-station tool post for quick tool changes and strong rigidity. The tailstock features an MT5 taper, Φ75mm quill diameter, and 130mm travel, facilitating the machining of long shaft parts.

6. Multiple CNC System Options
The machine can be flexibly equipped with various well-known CNC systems (such as FANUC, Siemens, GSK, KND, etc.) according to customer requirements, providing intuitive programming interfaces and precise motion control to meet different production habits and automation integration needs.
