The complex integrated design is simplified into 3 components. The components are assembled together with high precision after processing.

2.Process Upgrade: Instead of using milling, ultra-precision grinding is applied to key mating surfaces to ensure a positioning accuracy of flatness within 0.015mm, and work is done in a temperature-controlled workshop with a temperature of 22℃ to prevent dimensional variation due to temperature variation, along with artificial aging processes in rough machining to relieve internal stresses.

3.Improved Inspection: 100% of the parts will be fully dimensioned inspected using an ultra-high-precision coordinate measuring machine, focusing on inspecting the location of the mounting holes. Every part that passes through our hands also gets an analysis report that helps our customers see for themselves how our accuracy truly is.

Final Results Achieved

The optimizations carried out ensured that the end product completely satisfied customer needs and exceeded them in the following ways:

• Accuracy achieved: The accuracy achieved in the critical dimensions of the components was within ±0.01mm, and the flatness was <0.015mm, surpassing the requirements by a considerable margin.
• Increased Yield: The product pass rate improved from 85% to 99.8%, where only two pieces needed to be worked on again because of minor scratches, leading to no quality issues in the batch.
• Lowered Costs: The cost per piece was decreased to $130, a 35% decrease from that of the original supplier, thus providing a total cost savings benefit for the customer of $7000.
• Reduced Delivery Time: It took only 2 weeks to make the delivery to the customer in Germany, which was 5 days sooner than previously required.
