They employ skilled machinists who operate sophisticated equipment to deliver components with tight tolerances and excellent surface finishes. This combination of advanced technology and human expertise makes contract machine shops invaluable partners for companies that need high-quality machined parts but don’t have the resources or need to maintain in-house machining capabilities.
What is a Contract Machine Shop?
A contract machine shop is a specialized manufacturing facility that provides machining services on a contractual basis to other businesses. These shops focus specifically on precision machining operations using equipment like CNC mills, lathes, grinders, and other advanced machinery to produce metal or plastic components according to client specifications.
The distinction between a contract machine shop and other manufacturing facilities lies in their operational approach. Contract machine shops typically excel at consistent production of precision components, maintaining tight tolerances and high-quality standards. They often develop expertise in specific materials or industries, allowing them to offer specialized custom machining solutions that meet exacting requirements.
