At Ingenious Machinery (formerly YDPM), CNC machine quality control is built into every machine that leaves our factory. We don’t just build machines; we build trust. Our comprehensive quality control process ensures each product meets international standards of accuracy, reliability, and durability.
Our Quality Policy
We are certified to ISO 9001:2015, and our quality policy is simple yet powerful:
「穩定品質、持續改善」
Stable Quality, Continuous Improvement
This philosophy guides everything we do — from the selection of raw materials to the final machine inspection — ensuring our customers always receive products they can depend on.
Our Quality Assurance Process
-
Incoming Parts Inspection
Every component is carefully checked with advanced measuring instruments to confirm that it meets strict precision requirements
-
Geometric Accuracy Testing
Using global standards (ISO 10791-2), we test linear and perpendicular movements of each machine axis to guarantee geometric integrity
-
Laser Interferometer Calibration
Machines are calibrated with laser systems (ISO 230-2, VDI 3441) to ensure full-travel positioning accuracy across all axes
- Rotary Axis Verification
We measure angle positioning and repeatability to confirm that rotary movements achieve flawless precision
-
Circularity & Simultaneous Motion Testing
With advanced circular tests (ISO 230-4), we ensure perfect roundness and synchronized multi-axis motion
-
Spindle Reliability Checks
- Thermal growth: Testing spindle elongation at high speeds
- Noise & vibration: Confirming performance against ISO standards (230-5)
- Vibration Inspection: Verifying whether the spindle vibration levels meet the required ISO standards. ( 230-8)
- Clamping force: Ensuring drawbar pull force stability
- 5-Axis Error Compensation
With Laser R-Test (LRT) technology, we analyze and compensate for five-axis motion errors, elevating multi-axis machining accuracy to world-class levels
Why It Matters
-
International Standards
All inspections align with ISO testing protocols for global credibility. -
Zero-Compromise Reliability
From the smallest part to the final assembly, nothing leaves our facility without passing every stage of inspection. -
Customer Confidence
Our customers know that when they choose Ingenious, they receive not only advanced technology but also peace of mind that the machine is proven to perform.
The Ingenious Standard
Our quality control process is more than a checklist — it’s the backbone of our brand. Guided by our ISO 9001:2015 commitment to “穩定品質、持續改善”, we deliver precision, reliability, and continuous innovation for every customer.
