Product Description

Service Process for Precision CNC Machined Stainless Steel Threaded Couplings for Hydraulic Systems

1. Pre-Production Collaboration

(1) Requirement Confirmation
Confirm coupling type, thread standards (metric, BSP, NPT, etc.), nominal size, pressure rating requirements, sealing method, material grade, surface condition, order quantity, and delivery schedule.

(2) Drawing & Specification Review
Review 2D drawings or 3D CAD models detailing thread profiles, internal flow paths, tolerance requirements, and sealing interfaces.

(3) Application & DFM Analysis
Evaluate machining feasibility, thread accuracy, and sealing performance to ensure compatibility with hydraulic system requirements.

2. Process Planning & CNC Machining

(1) Material Selection
Select stainless steel grades such as 304 or 316 based on corrosion resistance, pressure resistance, and working environment.

(2) CNC Programming
Develop CNC turning and milling programs for precise internal and external threading, sealing surfaces, and connection features.

(3) Machining Simulation
Simulate machining processes to optimize tool paths, maintain thread consistency, and reduce burr formation.

3. Production & Quality Control

(1) Precision Machining
Perform CNC machining to produce accurate threads, smooth sealing surfaces, and stable internal flow passages.

(2) Thread & Dimension Inspection
Inspect thread profiles, pitch, diameter, and concentricity using thread gauges and precision measuring tools.

(3) Surface & Cleanliness Control
Ensure parts are free from sharp edges, burrs, and contamination to support reliable hydraulic sealing.

4. Post Processing & Delivery

(1) Optional Surface Treatment
Apply passivation or polishing to enhance corrosion resistance and surface quality if required.

(2) Cleaning & Packaging
Clean couplings to remove machining residues and package with thread protection to prevent damage during transport.

(3) Delivery
Deliver finished couplings according to agreed logistics terms and production timelines.
