A customer should be sure that the machine shop they choose is able to handle the number of challenges that may arise during the CNC machining process, and have the resources, communication, and quality control necessary to handle those challenges. If the precision machine shop can’t handle these issues, then the customer can waste valuable time and resources.
So Worthy Hardware would like to introduce 5 factors for you when you choose the precision machine shop as your vendor.
Factor 1: Experienced and Stable Core Managerial and Technical Team
A company with an experienced managerial, technical, and manufacturing team that has a wealth of knowledge is vital. The more experienced the shop is, the more hands-on they can be with new projects. Experienced manufacturing engineers are often able to quickly identify and offer alternate solutions when problems arise based on previous ordeals in projects. They are even able to help design your product to make it "design-for-manufacture" friendly, allowing an OEM to save time and money on assembly. More importantly, assist an OEM to stay ahead of the competition by achieving faster time-to-market for their new products.
For Worthy Hardware, most of our engineers have more than 10 years for CNC machining industry and they are very stable with our company.
Quality control is an important factor for any manufacturer's capabilities. A great way to learn about a factory's quality control process is to look at their certifications and auditing reports. Factories should at least obtain an ISO 9001 certification which confirms quality management.
It is just as important to review the shop's internal audit reports from operations to management, to warrant that all levels of quality are met. Factories should have detailed and accurate information on each equipment being used to detect specification accuracy, control standards, and response measures to keep rejection rates low and production yield high. A quality precision machine shop that is confident and proud of their products would be open to discuss their failure rate as well as their objectives and goals in reducing the failure rate to more suitable levels.
Communicating specifications for parts and prototypes to the precision the machine shop should always go beyond the initial order contact. Changes to the project can happen at any time. If the machine shop misses the call, the customer will have their doubts about working with the shop ever again and will share their dissatisfaction with their own clients that may prevent the machine shop from obtaining additional orders. A quality CNC machine shop should focus on four specific aspects of customer communication:
Spends time to elaborate on the capabilities and knowledge the machinist offers to the customer to implement the job.
Asking pertinent questions in regards to the project and how to maximize the job to the fullest potential so the customer receives value for their money
Allows the customer to select the channel of communication that best fits into their preferences
Provides a single point of contact who is ready to answer questions and implement changes immediately to minimize loss time and material waste.
Being within the required tolerance is very important. Tolerance is the clearance range in size a component needs to be within in order to fit into another component. For example, a metal piece is measured to be 8.25” but it cannot be any larger than 8.255”, which means that the tolerance level is .005". If it's too small, the metal piece will not reach across the entire component it is being inserted in and if it is too big the metal piece will not fit in its designated location. More and more industrial applications require increasingly tighter tolerances. The aerospace and medical industries, for example, are well known for its stringent tolerance requirements that call for a quality precision machine manufacturer. These levels challenge machine shops to continuously deliver quality products within their specified tolerance levels, in order to meet the essential overall tolerance a final product requires.
Different CNC shops have different types of equipment and different areas of expertise. This includes the types of materials that they can work with. You will want to ensure that the shop is able to work with the material that you have.
For example, if your material is fragile or brittles, the machine shop should have experts in wire Electrical Discharge Machining (EDM) services. This will allow them to cut through the delicate material by the use of heat while preventing rust.
