Number 1 & 2 Cylindrical Grinders

Superior Quality, Consistent Performance and Built to Last


Designed and built for long life and shop floor productivity, Parker Majestic’s No. 1 & 2 Cylindrical Grinders are easy to set-up, offer user-friendly operation and provide superior accuracy at an affordable price.

Quality . . . Designed-In from the Start
Parker Majestic’s commitment to quality is evident in every component we manufacture from our machine bases to high-precision spindles. Each machine is constructed from hand-scraped cast iron to provide excellent durability and years of accurate, reliable operation. Parker Majestic’s design engineers carefully integrate heavy-duty ribbing and vibration dampening slideways into every system. Our 73 year reputation for accuracy and dependability makes our grinders the first choice for demanding applications requiring superior performance. Ask your sales engineers about any customization you may need for your special application.

Precision Grinding Spindles
Parker Majestic’s complete line of precision spindles and complimenting tooling options offers solutions to the most difficult and demanding applications. As a leading manufacturer of precision spindles, we build spindles with ABEC 7 or better class bearings that are accurately balanced and vibration-tested to rigorous laboratory standards.

Workheads . . . Consistent and Reliable
As a manufacturer of precision spindles, Parker Majestic is known throughout the industry for our ability to produce workheads that consistently deliver accurate part holding. In fact, beyond manufacturing workheads for our own line of machines, we design and build workheads for other industry OEMs as well. So, whether you’re chucking large solid carbide dies or small delicate parts, you know that you can count on Parker Majestic’s heads for less than .000040" (.001 mm) T.I.R. Our workheads also allow for a variety of workholding techniques. A dead center drive is provided for external grinding between centers, and chucks or face plates can be mounted for part chucking. Additionally, a 5C collet taper is ground into the shaft for the convenience of collet chucking.
