The Sunnen CRG-2000 is a versatile honing/grinding machine built for precision machining on cylinder caps, rod journals, bearing surfaces — ideal for engine builders, remanufacturers, or machine shops doing crankshaft balancing, rod work, or journal refinishing. As a used unit, the CRG-2000 offers a cost-effective way to add professional-level grinding/honing capability to your shop without investing in a brand-new machine.
With a powered ¾ HP motor at 115 V, the CRG-2000 is compact enough for many shops but robust enough to handle demanding jobs. It’s suited for small- to medium-volume crank/rod rebuilds, journal cleanup, or precision finishing where accurate diameter and surface finish matter.
Because this is a used machine, it’s an economical option for shops looking to expand capabilities — especially for rod/shaft rebuilding, journal grinding, and related tasks — at a significantly lower cost than a new unit.
Capable of Precision Journal & Rod/Cap Grinding — Designed for grinding or honing caps and rods to ensure accurate surfaces, proper alignment, and consistent finish — critical for engine balance and performance.
Compact & Shop-Friendly Footprint — Smaller size and 115 V power requirement make it practical for many machine shops, even those without large-machine capacity.
Versatile for Rod & Crank Work — Useful for rod/rod-cap resurfacing, journal cleanup, aligning bearing surfaces, or prepping rods/cranks for rebuild.
Cost-Effective Used Machine Option — Offers many of the benefits of new, more expensive grinding/honing machines at a lower entry price — ideal for shops scaling up capabilities.
Suitable for Small to Moderate Volume Work — Especially well-suited for engine rebuild shops, performance shops, and mixed-use rebuild/repair shops that don’t need high-volume production machines.
Flexibility in Use — Can be used for a variety of tasks: journal grinding, cap rework, honing, precision finishing — giving shops more flexibility in how they use the machine.

Decades before today’s engine shops trusted our equipment, Tony was already deep in the craft — rebuilding motors, machining blocks, and pushing for better precision.
A local newspaper once featured him as a standout young machinist, noting his drive, attention to detail, and obsession with doing things the right way. That same passion would eventually shape our company’s values.
Today, that commitment lives on in every machine we sell, every customer we support, and every shop we help succeed.
