The right grinder for the application. Nothing more, nothing less.
Grinding Advisor helps manufacturers choose CNC grinding machines — cylindrical, internal, centerless, and vertical. We don't sell machines and we don't take sides between builders. Tell us what you grind, and we'll match you with the right machine for the job.
How it works
Three steps. No sales pitch.
Buying a grinder is a six-figure decision you'll live with for a decade. We make the front end of that decision straightforward.
Tell us your application
Parts, materials, tolerances, volumes, timeline. The more specific you are, the better the match. A drawing beats a paragraph.
We match the machine
We compare builders on capability, not marketing. Right process first — cylindrical, ID, centerless, vertical — then the right machine inside it.
We make the introduction
You talk directly to the builder: test cuts on your drawings, firm quotes, installation and training. We stay available without getting in the way.
Machine types
Know the process before you shop the machine
Most bad grinder purchases aren't bad machines — they're the wrong process for the part. Start here.
Cylindrical (OD) grinders
External diameters: shafts, spindles, pins, rollers. The workhorse of precision grinding.
When OD grinding is the call →Internal (ID) grinders
Bores, bearing seats, internal diameters. Chuck or between-centers workholding.
ID configurations explained →Universal grinders
ID and OD in one machine. The toolroom answer for high-mix, low-volume work.
Who should buy universal →Centerless grinders
High-volume OD work with no centers: thrufeed bars and pins, infeed for formed parts.
Thrufeed vs infeed →Vertical grinders
Bearing races, cam profiles, large heavy parts. Big swing, gravity working for you.
Where vertical wins →Controls compared
Fanuc vs Heidenhain vs Siemens on grinders: familiarity, service, and what your people already know.

Grinding is the last step that decides the part
Bearing races, transmission shafts, implant tapers, turbine components — grinding is the final sizing and finishing operation, and it's where tolerances are won or lost.
Bearings
Raceways and rolling elements at micron tolerances. Vertical and ID grinders do the heavy lifting.
Grinding for bearings →Automotive
Transmission shafts, gears, CV joints, camshafts. High volume, tight process control.
Grinding for automotive →Aerospace
Turbine disks, shafts, landing gear. Documented process capability isn't optional.
Grinding for aerospace →Medical
Implant tapers, bone-screw threads, instrument finishes. Validated processes, zero scrap tolerance.
Grinding for medical →Energy
Turbine shafts and blades, oil and gas components. Large parts, long cycles.
Grinding for energy →New vs used: total cost
A used Studer at auction vs a new value-tier machine. We run the honest math — used wins on sticker price.

Advice you can use, from people with no machine to sell
We don't sell machines
Grinding Advisor isn't a dealer and doesn't stock inventory. That means our only incentive is a good match — a bad recommendation earns us nothing and costs us everything.
Buyers never pay
When an introduction turns into a closed sale, the manufacturer pays us a commission. You pay nothing for the guidance, the comparison, or the introduction.
Built by manufacturing people
This site is written by people who've run grinders, managed manufacturing budgets, and sat through the hurry-up-and-wait of capital equipment buying. The content shows its work.
Honest about trade-offs
Every machine type has a job it's wrong for. We say which, on the page, before you talk to any salesperson — including the ones we introduce you to.
The archive
Manuals and fixes, searchable
We're building a public library of machine manuals, catalogs, and resolved maintenance issues — the documentation maintenance teams actually need, in one searchable place. No more digging through tribal knowledge and binders. Search the archive →
