When gathering information about any machining vendor you’re considering, you must first access the certifications they’ve obtained. A crucial certification you must look for is ISO 9001.
ISO 9001 is a standard that specifies the requirements for quality management systems. An ISO 9001-certified machine shop adheres strictly to statutory and regulatory requirements by ensuring high-quality machining services.
Once you verify that the machine shops’ certifications meet your requirements, you must then determine the type of CNC machining equipment they have in their facility.
2 The Type of Machining Equipment Affects the Quality of Machined Parts
The type of CNC machines used to create prototype (or production) parts plays a significant role in the quality of parts you’ll receive. CNC machines come in many varieties and are typically classified by the number of axes they can operate within, for example, 2-, 3-, 4- and 5-axis CNC machines.
As one may imagine, 5-axis CNC machines are more advanced than 2-, 3-, and 4-axis CNC machines. They offer better relational accuracy, and surface finish, and, more importantly, can machine complex shapes. Not all parts require 5-axis machining (like the one pictured above), but if a part is complex enough, it could be the ideal solution.
Third-party machining vendors that incorporate advanced CNC machining technology in their facility seek to ensure high-quality machined parts. But that’s not all you should look out for in a third-party machining vendor!
The quality of machined parts also largely depends on the level of expertise of the CNC operators that will be fabricating your parts.
3. Quality CNC Machining Depends on the Technician Operating the Machine
There have been many horror stories of customers receiving low-quality and unusable CNC machined parts, even though the manufacturer boasted about certifications and state-of-the-art machining equipment. More often than not, these issues are traced back to the CNC machine operators.
The truth is that there is a skill gap for CNC machine operators. The machining market is flooded with operators who learned from the “school of hard knocks” and are prone to making the same machining mistakes repeatedly.
And to complicate matters, many machine shops lack a standard quality management system to inspect the parts being fabricated by their operators or technicians. You must steer clear of these types of vendors.
4. Top-tier CNC Machine Shops Perform Three Types of InspectionTop-tier machining shops typically carry out three types of inspections at different stages of the manufacturing project;
Inspection by the machine operator: here, the operator carries out various article inspections during (or immediately) after machining to identify tolerance problems. It involves using simple measuring tools such as go/no-go gauges and micrometers. Inspection via in-process probing: describes an automated way of verifying key features and tolerances of a part during the CNC machining process using programmed probes. These probes automatically monitor the process and adjust work coordinates and cutting tools accordingly. Inspection in the quality control (QC) department: it describes the inspection stage carried out on CNC machined parts by a team of quality control experts. These QC experts utilize height gages, microscopes, 2D projectors, micrometers, and coordinate measuring machines (CMM) to ensure that parts conform to the customers’ requirements. The picture above shows one of our QC team members at Chiheng Hardware operating a CMM machine.Dongguan Chiheng Hardware Co., Ltd is a leading provider of high-quality CNC machining services. We have a complete quality management system in place, and our facility is ISO 9001:2015 certified for quality.
1. Do you have quality inspection in your factory? do you provide a quality inspection form with all measurements?
---Yes, of course we have. Testing reports will be provided if needed.
2.What is the average delivery date?
---Samples, it will take about 7-10 days.
Mass production, it may cost 10-20 days, depends on the quantity and processing degree.
3. What is your MOQ?
---We have no certain MOQ, welcome produce prototype as a trial.
4. What equipment do you have?
---We have advanced CNC machining centers, CNC turning lathes, CNC drilling lathes, CNC milled machine,stamping
welding equipment&high-educated engineers so we can make products according to your drawings or samples.
5. Is the material ROHS compliant?
---Yes, the material is complied with ROHS certification.
6. Will your company sign an NDA?
---Yes, of course. We can sign an NDA before you send us the drawings or design scheme.
7. What is your machining tolerance and roughness?
---We can reach the tolerance +-0.005——+-0.01mm. The roughness we can reach with Ra 0.6——Ra3.2.
8. How does your factory control quality?
to help detect and minimize defects.
9. How will you deal with the faulty?
