In our product design process, sample run of precision machined parts is limited by some of the most rigorous inspection procedures. The test method we use proves to the customer that the part meets the specified tolerances and is free from defects. From magnetic particle inspection to laser scanning, we ensure that each new product passes a series of tests before being shipped to the customer.
We regularly use powerful inspection techniques to detect and diagnose any defects or defects in metal parts. In some cases, we use these methods to reverse engineer existing parts with defects. In other cases, we have identified deficiencies in the initial design that have led to downstream manufacturing challenges.
We are proud of quality, which means great attention to inspection. Our plants use state-of-the-art quality control methods throughout the production process to ensure that precision mechanical parts are processed to meet or exceed expectations. Further, our CNC machine tools are excellent in the quality control department. With the detection capabilities at the forefront of measurement technology, it is possible to diagnose performance problems, determine the cause of any defects, and even recommend changes to the manufacturing process.
Inspection varies from part to part, depending on the shape and size of the machined parts and the material composition. If a defect is suspected, the inspection strategy will also be notified. The following technologies include samples of quality control methods used by our CNC processing plants.
First, manual measurement
Manual measurements are made using micrometers, calipers, altimeters, pins, plates and other tools.
1, for simple products with lower key areas;
2, advantages include fast setup and low-cost tools;
3. Disadvantages include the time involved in the measurement, lack of repeatability, and difficulty in measuring the surface.
Second, the coordinate measuring machine (CMM)
A range of measuring devices, from manually configured measuring stations to portable laser scanners, allow accurate measurements with reduced human error.
In precision machinery parts processing operations, CNC machining controls CMMs and portable laser arms. Each device has different strengths and weaknesses, from setup time to repeatability and accuracy. With existing equipment, radial or linear tolerances of +/- .0003″ and surface finishes as low as 32ra can be measured.
Third, portable laser scanner
The use of portable laser scanners for precision machined parts measurement technology facilitates inspection and reverse engineering.
1, complex products for complex surfaces;
2, advantages include saving time, easy to set up, the ability to accurately measure curves and the ability to overlay coordinate grids onto nominal 3D files;
3. Disadvantages include equipment costs and advanced software training needs.
Our CNC processing equipment manufacturers and our processing plants can work together to complete this processing need.
By performing all of these tests, we wait for responsible manufacturers to ensure that all defects are found before entering full production. If any defects are found, this comprehensive inspection process ensures that the engineer can diagnose and resolve the problem.
