CNC Milling
For plates, housings, brackets, fixtures, cavities, and multi-hole components.
Machining Capabilities
From Drawing Review to Precision Machining, Prototypes to Volume Production
LIFAN provides CNC milling, 3-axis and 4-axis machining, grinding, drilling and tapping, plus coordinated finishing. Typical lead time is 7–15 days, subject to material, geometry, volume, and quality requirements.
Capability Overview
We support build-to-print work and sample-based evaluation. Orders can start from 1 piece and extend to pilot runs and 10,000+ piece production programs.
3-Axis / 4-Axis Machining
For multi-face features, angled holes, contours, and complex geometry.
Precision Grinding
For flat surfaces, mating faces, and improved surface-quality requirements.
Drilling / Tapping
Efficient production of hole patterns, threads, and repeat components.
Build-to-Print / Sample-Based Work
Evaluation of material, geometry, process, and inspection from drawings or samples.
Prototype to Volume Production
Single parts, pilot batches, and 10,000+ piece program evaluation.
Main Processes
Milling dimensions can be evaluated up to approximately 850 mm, with stable tolerances referenced at 0.01 mm. Final capability depends on material, geometry, workholding, dimension distribution, and inspection method.
CNC Milling
Model-850 CNC capacity supports milling dimensions evaluated up to approximately 850 mm for multi-face, cavity, hole-pattern, and fixture work.
3-Axis and 4-Axis Machining
Three-axis and four-axis process planning reduces accumulated error from repeated positioning on complex parts.
Precision Grinding
5 grinding machines support surface finish evaluated from Ra 0.2–0.8.
Drilling and Tapping
11 model-650 machines support efficient hole, thread, and batch-component production.
Surface Preparation and Cleaning
Sandblasting, brushing, ultrasonic cleaning, and laser marking are available alongside coordinated finishing.
Flexible Production
Single prototypes, pilot runs, and volume production begin with controlled drawing revisions and first-piece approval.

Production Modes and Public Parameters
Prototype and One-Off Machining
Orders can start from 1 piece for fit checks, assembly validation, replacement parts, and new-product trials.
Pilot and Small-Batch Production
Programs such as 50, 100, and 1,000 pieces are evaluated with drawing control, first-piece approval, and in-process consistency checks.
Volume Production
10,000+ piece programs can be evaluated using capacity planning, first-piece confirmation, in-process sampling, and final inspection.
Tolerance and Surface Finish
Stable tolerance can be referenced at 0.01 mm. CNC finish can be referenced at Ra 1.6, with grinding evaluated at Ra 0.2–0.8.
Capability Notes
Tolerance and roughness depend on material, geometry, and inspection conditions
Maximum size is an evaluation reference, not a guarantee in every axis
Finishing depends on process, color, coating thickness, and cosmetic standards
Lead time depends on material, volume, process sequence, and capacity
Customer names, drawings, dimensions, and proprietary structures remain confidential
A Drawing Enables a More Accurate Machining Assessment
Provide material, quantity, drawings, finishing, and target lead time. Engineering will review process, equipment fit, inspection points, and delivery planning.
