At Volunteer Sintered Products, Inc., we provide CNC machining services as a complement to our sintered powdered metal part manufacturing capabilities. Powdered metal sintering technology allows us to manufacture complex parts to near final dimensions and profiles, but sometimes CNC machining operations are needed to achieve closer tolerances or the desired finish. With our ability to provide CNC machining services in-house, we provide you with a single source solution for parts that meet your exact requirements.

As powder metallurgy specialists, we have a deep understanding of how the porosity and microstructure of sintered metal parts impact cutting tool selection and other aspects of the machining process. We often recommend resin impregnation of powder metal parts to improve their machinability. Our machining capabilities include CNC milling and surface grinding, which allows us to uphold overall dimensional tolerances of ±0.0002” and produce exceptionally fine surface finishes.

We are an ISO 9001:2008 certified company and our machining processes are backed up by our comprehensive quality assurance program. Since 1981, we have been providing customers in the automotive, firearms, power tool, home appliance and many other industries with quality parts that improve their products. Examples of products we manufacture include fixtures, gears, gauges, bushings, hinges, and many more.

We have engineers on staff to assist you with any aspect of product development. With the ingenuity that comes from 30+ years of industry experience, we often find inventive solutions that improve fit and functionality while saving significant expense. Contact us today to learn more about our CNC machining capabilities.
