A machine shop is essential for designers and engineers to source the parts created through grinding, fabrication, CNC machining, milling, and turning. When ordering parts for CNC machining, you may need a machine shop with compatible services for the project requirements. For this reason, we will tell you how you can find and choose the best precision machining services.
How to select the best precision machining services?
1. Know the experience
The first important tip in choosing the best precision machining services is to find a company with good experience. You will have to look for someone who has been in the business for some time.
Shops with an in-depth experience in manufacturing are built over the years. They will be knowledgeable about the production processes and have a good reputation for product fulfillment and customer service.
2. Review offering of equipment
Another thing that you must look out for while selecting a precision machining service is what systems and technologies they provide. For example, if the part needs five-axis CNC machining, there will not be a point in starting any discussion with a service that only comes with three-axis machines.
You must check the roster of the service machine listed on the websites to see that you have the right manufacturing equipment.
If you have a strict schedule, you can check how many machining systems the precision machining service has in their operation. Also, a shop that has two machines will be able to offer the same kind of turnarounds as a large service with hundreds of machines.
3. Look for a quality assurance team
You can check if the shop has diverse materials like stainless steel and titanium or the more common and soft aluminum 6061. This will indicate that the shop has the varied manufacturing experience to handle your future and present requests.
4. Secondary finishes and operations
A manufactured part may need finishes like chemical conversion coating, nickel plating, electroplating, or even anodizing. It may also require features like laser marking, silkscreen, and installed inserts before shipment. Selecting a precision machining service that can perform secondary operations and finishes will give you an all-set component.
5. Operational risk
A good precision machining vendor will have an individual and a team to work on the parts and rectify any problems that may arise. Precision machining services only rely on a single person for doing everything from machining to quoting and quality assurance, which can indicate an operational risk. If anything happens to the person, your job can be sidelined.
You must avoid such risks by checking the activities and distribution of the vendor across the personnel range.
The vendor that you select should be easily accessible. You can evaluate the potential vendors by paying close attention to the responsiveness in the early stages of the engagement.
While calling them, does anyone pick up, or do you just hear the voicemail? Do you get an email response or a prompt return call after leaving a message? The communication skills of a shop are significant for a long-term relationship with the vendor.
7. Checking for certifications
To determine the establishment of a precision machining service, you must check for its certifications. For example, if you need to manufacture aerospace application parts, you must go to a machine shop of the highest quality.
You must also ensure that the production facility has the necessary certifications.
The production partner must have medical-grade facilities and necessary certifications if they order medical components and devices.
Beyond the above-listed certifications, there are other certifications that you must keep an eye out for. These include :
- Material documentation
- quality assurance certificate
8. Evaluating lead times
Evaluating lead times is another factor that will help you choose the best precision machining services. You need to know whether manufacturing partners can deliver and machine a part within the required time frame.
Most quality machine shops list their usual turnaround times. However, these vary depending on the manufacturing job’s scale and complexity.
Nowadays, advanced precision machining services provide automated software for quoting that indicates the estimated production cost and how long the order will take to manufacture and process. This makes it easier for the customers to proceed with orders and to understand what they can expect.
It is also better to make sure that the precision machining services provide tracked, fast shipping for the final parts.
9. Geographical location
Location is also quite important when finding the best precision machining service provider. The major advantage of choosing an agency for precision machining is that you can save logistic costs.
Sometimes precision machines fail to function properly. For this, getting a service provider near you may help. They can reduce your downtime by quickly responding to your primary concerns.
To find the best precision machining service provider, you need to check their experience, see their certifications, and evaluate their lead times along with their responsiveness. xcentricmold.com provides precision machining services with cutting-edge technologies with a team of experienced and expert engineers.
