When choosing a CNC lathe, the key is to match your machining needs with the equipment's performance, avoiding both "overkill" and "difficulty in using a low-end machine." Based on the current market situation, here's a practical buying guide for you:
Clearly defining processing requirements is a prerequisite.
Part Size: Small parts (e.g., φ5-50mm) can be machined on a small lathe such as the CK6132; for large diameter or long shaft parts, a horizontal lathe of CK6180 or higher is recommended.
Material Type: For machining soft materials such as aluminum alloys, ordinary servo motors can be used; for cutting hard materials such as 45# steel and stainless steel, a frequency converter and a high-torque spindle are required.
Precision requirements: For general parts, a tolerance of ≤0.02mm is sufficient; for aerospace and medical components, a tolerance of ±0.005mm is required, and high-end models should be selected.
Key Configuration Parameters to Consider:
Spindle Speed: Generally 100-3000 RPM, ≥2000 RPM is recommended for thread machining.
Tool Post System: 8-position electric tool post is preferred for fast tool changes and good stability.
Guideway Type: Slant bed + linear guide structure offers high rigidity and better accuracy retention than flat bed.
CNC System: For domestic systems, Huazhong and Guangshu are recommended; for imported systems, FANUC and SIEMENS are good choices for superior stability.
Brand and After-Sales Service Selection Recommendations
Automation Integration: Prioritize models that support robot arm docking and have standard interfaces.
