TRUSTED AND DURABLE CYLINDRICAL GRINDING MACHINE
G&P Machinery. Built for the Long Haul.
A cylindrical grinding machine is only as good as the engineering behind it. G&P Machinery has been designing and building cylindrical grinding equipment in Indianapolis, Indiana, since 1952, and the shops running our machines decades after purchase are the most honest testament to that.
If a cylindrical grinding machine sits at the center of your production process, it needs to deliver consistent performance, maintain tight tolerances, maximize uptime, and remain reliable long after lesser equipment would have been replaced.


Precision Without Compromise
A cylindrical grinding machine that drifts out of tolerance, deteriorates under sustained production loads, becomes difficult to maintain, or makes replacement parts hard to source can create problems that ripple throughout an entire operation. Rework, downtime, repair expenses, and replacement costs all add up quickly.
G&P Machinery builds cylindrical grinding machines specifically to avoid becoming that problem, with engineering focused on durability, precision, reliability, and long-term serviceability from the moment the machine leaves the floor.
Equipment Built to Match Your Production Needs
Cylindrical Polishers
G&P Machinery's cylindrical polisher is a dedicated cylindrical grinding machine designed to polish straight shafts, tapered shafts, cylindrical components, and outside diameter surfaces to a consistent, uniform finish. Precision bearings and a tapered spindle design hold close tolerances through extended production runs, making this machine well suited to both custom work and continuous high-volume output.
Lathe Mounted Roll Grinders
The lathe-mounted roll grinder converts an existing lathe into a capable outside diameter cylindrical grinding machine, extending your shop's finishing capability without the footprint or cost of a standalone unit. A range of contact wheels accommodates roughing passes, intermediate grinding, fine finishing work, and specialised surface requirements across a variety of part geometries and materials.
Grinder Mounting Options
G&P Machinery’s grinder mounting options provide a flexible route to expanded cylindrical grinding capability by integrating compact, medium-duty, heavy-duty, and special abrasive belt grinder configurations into existing equipment, offering a practical and cost-effective solution for operations that need more cylindrical grinding capacity without committing to a full new machine purchase.
Custom Cylindrical Grinding Machines
When a standard cylindrical grinding machine configuration does not meet the specific demands of your production process, G&P Machinery engineers a custom solution built around your exact requirements. Every custom cylindrical grinding machine is manufactured in the USA with the same material standards, precision engineering, parts availability, and direct technical support that define the entire G&P product line.
