Which good precision CNC machining?Weihua technology (china cnc precision machining) professional commitment to precision hardware parts customized processing, processing precision, high efficiency, stable performance, welcome to inquire!

What requirements should high quality CNC precision manufacturers have?

Over the years, although the emergence of precision CNC processing manufacturers, but on the market in many areas of the product requirements are relatively high, not ordinary machining manufacturers can be competent, the choice of high-quality precision CNC processing manufacturers is more important, how to measure users?

Many procurement are facing this problem, weihua technology committed to precision CNC machining has more than 10 years of experience, involved in a number of industries of product customization and batch processing, for you to summarize, in the choice of high-quality precision CNC machining manufacturers need to consider several aspects.

Mainly speaking, the user must pay attention to whether the factory has a standard processing implementation plan, whether there is a professional and standardized process, whether the product delivery ability has, below, we around these points for everyone to elaborate.

1. Implementation of conventional processing standards

For the processing standards, as long as it is engaged in CNC precision CNC processing enterprises, should pay attention to this.Processing standards are products made after the accuracy of the guarantee, only in line with the standard to produce qualified products, the production of defective products on the user is not so simple to invest, sometimes, because an accessory is defective products and affect the user's overall project, the loss is difficult to estimate.

Conventional processing standards such as:

Whether the processing requirements of the structural assembly groove on the mold kernel are the same as the processing requirements of the same mold embryo;

In the processing and discharge diagram, the number is calculated according to the engineering part diagram.

Whether to do parting surface polishing tool allowance small mold can not exceed 0.05mm/S, and large mold can not exceed 0.08mm/S, and so on.

2. Standardized operation process

Operation process is to ensure the product quality of the foundation, in the choice of mechanical processing plant, must have a certain understanding of the precision CNC processing plant operation process.

A little more details to understand, such as: before the security boot check, boot zero, boot warm up according to the requirements;Procedure single mold number, workpiece number, reference Angle azimuth, XYZ triaxial number method and number of the plane to determine whether it is reasonable;

Clean and tidy the clamping before the workpiece is put on the machine and check the fastening of screws and the calibration of the workpiece;Recheck tool and safety check and machining data check at the beginning of machining;

Before getting off the machine, the workpiece cleaning and so on the relevant processing operation process is standard, whether there is a clear provision.

3. Quality of workpiece delivery

The workpiece delivery quality is the most intuitive way to reflect the strength of the precision CNC processing plant.Considering the quality of the workpiece delivery, we can understand the previous cooperation with the precision CNC processing plant.

Ask them if the surface quality and size of the workpiece they received are the same as the drawing.

Delivery quality also includes the delivery cycle, many manufacturers are claiming what free proofing, 3 days of delivery, etc., in fact, if it is to understand the industry people know, precision CNC processing manufacturers operating costs are not low, rent, manpower, mechanical equipment these costs are inevitable.

4. Strict quality control system

Many users in the inspection of time often ignores this, high quality precision nc machining manufacturer must have a set of effective and perfect quality control system, and small and disadvantage of factory is not willing to invest in this respect, take the equipment for China's science and technology quality department, spectrometer (mainly used for the qualitative analysis), three coordinates measuring instrument, projectors, surface roughness tester and so on, these devices are enough to purchase several numerical control equipment of the domestic, but for high standards of product testing, it were not for the measuring equipment is entirely unworkable.

Through the above analysis, do you have a deeper understanding of how to choose the suppliers of high quality precision CNC machining manufacturers?I hope I can help you.
