Product Description

Service Process for High Precision CNC Lathe Machined Stainless Steel Shaft Components

1. Pre-Production Collaboration

(1) Requirement Confirmation
Confirm shaft specifications including outer diameter, length, tolerance requirements, surface finish, straightness, concentricity, material grade, order quantity, and delivery schedule.

(2) Drawing & File Review
Receive 2D technical drawings or 3D models indicating key dimensions, tolerances, and functional features such as grooves, steps, chamfers, and threads.

(3) DFM Analysis
Review shaft design for CNC turning feasibility. Optimize machining sequence and clamping methods to ensure dimensional stability and concentricity.

2. Process Planning & CNC Turning Programming

(1) Material Selection
Select suitable stainless steel grades such as 303, 304, or 316 based on corrosion resistance, strength, and application environment.

(2) CNC Lathe Programming
Develop CNC turning programs for roughing and finishing operations. Optimize cutting parameters to achieve high dimensional accuracy and smooth surface finish.

(3) Machining Simulation
Simulate turning processes to verify toolpaths, avoid interference, and ensure consistency for batch production.

3. CNC Turning Production & Quality Control

(1) Machine Setup
Set up CNC lathes with precision chucks, collets, and cutting tools. Ensure proper alignment to maintain shaft straightness and concentricity.

(2) Shaft Machining
Perform CNC turning operations including outer diameter turning, grooving, threading, and end-face machining according to programmed parameters.

(3) Inspection & Testing
Inspect shaft diameter, roundness, straightness, and surface roughness using micrometers, dial gauges, and surface testers. Functional fit checks are performed when required.

4. Post-Processing & Delivery

(1) Secondary Processing (Optional)
Provide additional processes such as polishing, grinding, heat treatment, or passivation to meet specific performance requirements.

(2) Cleaning & Packaging
Clean finished shafts to remove oil and machining residues. Package with protective materials to prevent scratches and deformation during transport.

(3) Delivery
Ship products according to agreed logistics terms. Fast turnaround is available for prototypes and small-batch orders.
