In-Feed Grinding

In-Feed centerless grinding is available for parts that have shoulders or obstructions not allowing them to pass in between both the regulating and grinding wheels.  We have the capability to hold tight tolerances and ensure critical features are met per customer specification.  We have the ability to perform in-feed profile grinds allowing us to grind multiple diameters at once.   We have the capacity to process anything from prototypes to large orders in very short lead times.

Secondary In-Feed Services:
- At Express Grinding we also offer special buffing, polishing and wire brushing services allowing us to remove any size sliver burr or grind flash.  Sharp edges can be removed creating a radius if desired, however sharp edges can be maintained while still removing any sliver burr or grind flash after grinding.  Our Ultra-sonic washing system gives us the ability to remove any contamination whether it's from grinding or any prior operation.

Preventative Maintenanace:
- All pieces of equipment at Express Grinding have specific rigorous preventative maintenance programs in place to guarantee they are running at maximum efficiency, while ensuring a zero fall out rate. At Express Grinding we do not allow any room for error.  We believe that our quality can only be as good as the equipment used to grind and inspect our parts.  All of our equipment has either been purchased new or completely rebuilt and retrofitted with the most advanced technology
