CNC Eccentric Technology

Sanluo Precision's eccentric turning on CNC lathe uses advanced CNC technology. C-axis eccentric programming: CNC system C-axis function for spindle positioning and indexing, tools turning according to eccentric trajectory without eccentric clamping; programming methods include G-code programming, polar coordinate programming, parametric programming to automatically calculate tool trajectory; processing principle: workpiece center is at spindle center, tool offset by eccentricity, cooperating with spindle C-axis and X/Z-axis interpolation to form eccentric outer circle or inner hole. Processing advantages: simple clamping with workpiece concentric clamping without eccentric correction, clamping time reduced by 80%; high precision with C-axis indexing accuracy ±5″, eccentricity accuracy ±0.005mm, repeat accuracy ±0.002mm; multi-eccentric processing with one clamping for multiple eccentricities, C-axis automatic indexing, efficiency increased by 3 times.

CNC Programming Methods

Sanluo Precision's processing plant has efficient programming for eccentric turning on CNC lathe: polar coordinate programming with G15/G16 polar coordinate commands, setting eccentric center as pole, describing tool trajectory with polar radius R and polar angle θ (eccentric outer circle: spindle C-axis rotation, X-axis feeding eccentricity, Z-axis turning to obtain eccentric cylinder; eccentric inner hole: boring tool radial movement, cooperating with C-axis for turning eccentric hole); subroutine programming with eccentric contour as subroutine, main program calling C-axis indexing for multi-eccentric processing; parametric programming with eccentricity, eccentric angle, eccentric length as variables, modifying parameters for quick model change; simulation verification using CAM software to simulate, check interference and collision, optimize tool path to ensure program correctness.

Obvious Technical Advantages

As a professional manufacturer of eccentric turning on CNC lathe, Sanluo Precision has obvious technical advantages: improved efficiency (traditional eccentric clamping and correction takes 30-60 minutes, CNC C-axis programming clamping only takes 5 minutes, efficiency increased by 80%; program solidification for mass production with good consistency), guaranteed precision (high C-axis indexing accuracy, eccentricity accuracy ±0.005mm better than traditional ±0.02mm; no clamping error, eliminating human factors with CPK≥1.67), complex eccentricity (multi-eccentricity, variable eccentricity, irregular eccentricity flexibly realized by CNC programming, which cannot be processed by traditional manufacturing), automation (robotic loading and unloading, automatic program operation, 24-hour unmanned production), reduced cost (short clamping time, high processing efficiency, low labor cost, more obvious advantages for larger batches). We provide professional customized CNC lathe machining services for global customers, ensuring stable and reliable quality of each product.
