Product Description
Service Process for High Precision CNC Machined Fixtures for Automotive Component Testing
1. Pre-Production Collaboration
(1) Requirement Confirmation
Confirm fixture requirements including tested component type, positioning accuracy, clamping method, reference datum, tolerance requirements, material selection, order quantity, and delivery timeline.
(2) Drawing & File Review
Receive 3D CAD models or 2D drawings showing fixture structure, locating features, clamping points, and interface with testing equipment.
(3) DFM & Function Review
Conduct Design for Manufacturing and functional analysis to ensure fixture rigidity, repeatable positioning, and compatibility with automotive testing procedures.
2. Process Planning & CNC Programming
(1) Material Selection
Select suitable materials such as aluminum alloy, tool steel, or structural steel based on rigidity, wear resistance, and testing frequency.
(2) CNC Programming
Develop CNC machining programs for milling, drilling, tapping, and precision surface machining. Optimize toolpaths to ensure positional accuracy and surface flatness.
(3) Machining Simulation
Simulate machining processes to verify toolpaths, avoid interference, and ensure dimensional consistency.
3. CNC Machining & Quality Control
(1) Machine Setup
Set up CNC machining centers with precision fixtures and reference alignment to ensure repeatable machining accuracy.
(2) Fixture Machining
Perform CNC machining to complete locating surfaces, clamping structures, mounting holes, and reference features according to design specifications.
(3) Inspection & Verification
Inspect critical dimensions, flatness, perpendicularity, and positional accuracy using precision measuring tools. Assembly and fit checks are conducted with sample components when required.
4. Post-Processing & Delivery
(1) Surface Treatment (Optional)
Apply surface treatments such as anodizing, black oxide, or surface hardening to improve wear resistance and service life.
(2) Cleaning & Packaging
Clean finished fixtures and package with protective materials to prevent damage during transportation.
(3) Delivery
Deliver fixtures according to agreed logistics terms. Stable lead times are available for prototype fixtures and small-batch production.
