Cylindrical Grinding

Our cylindrical grinders are capable of performing various different grinds and multiple diameters at once.  Angles and spherical radii can be ground in our high precision collet systems or between centers.  Single and multiple outside diameters combined with angles or spherical radii can be ground at once, saving time and cost.  Our cylindrical grinders are capable of holding some of the industries tightest tolerances.

Secondary In-Feed Services:
- At Express Grinding we also offer special buffing, polishing and wire brushing services allowing us to remove any size slAt 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.
