Focused on centerless grinding. Do one thing, and do it the best.

Origins: Built on Spirit of Craftsman

High-Precision Centerless Grinding Machines,Customised Centerless Grinders, and Automated Grinding Solutions

The technical foundation of S-TYPE LTD., Co. can be traced back to 1991. In those early years, the senior generation of our founding team worked in a professional grinding machine manufacturing company, dedicating themselves to the production, process development, and application technology of centerless grinding machines.

Their belief was simple and unwavering:
“Spend a lifetime mastering one thing, and make it excellent.”

This philosophy remains the core value that continues to guide S-TYPE today.

For more than 30 years, we have been fully dedicated to centerless grinding — not only the machine itself, but the complete grinding process. Our experience covers machine structure and rigidity design, grinding process programming, infeed control, dressing and compensation, process stability, inline measurement, and full production line automation.

We do not simply build machines.
We deliver stable, repeatable, high-yield production capability.

Today, S-TYPE centerless grinding solutions are running in multiple industries and countries worldwide, including Germany, Switzerland, Spain, Bulgaria, Romania, Thailand, Singapore, India, China, Vietnam, the Philippines, and Korea. Our equipment and turnkey systems support both high-precision components and high-volume mass production.

• Roller-Type Diamond Dressing Mechanisms (for CBN and Diamond Wheels)
Superabrasive wheels such as CBN and diamond offer high hardness, long life, and aggressive cutting performance — but they are difficult to dress using traditional methods.
Our dedicated roller-type diamond dressing system provides fast, stable, and repeatable dressing performance. This allows customers to maintain wheel geometry, extend wheel life, and fully realize the advantages of CBN and diamond grinding wheels in continuous production.

• Form Dressing Systems for Conventional Grinding Wheels
When the part is not just a straight diameter — for example stepped diameters, tapers, radii, shoulders, angles, or complex contours — dressing quality directly controls cycle time and throughput.
Our in-house form dressing solutions can rapidly generate complex geometries on standard grinding wheels. This shortens setup time, improves repeatability, and supports stable, high-precision, high-volume centerless grinding.

This is not just “a machine specification.”
This is a production toolset.

What our customers receive is not only a centerless grinder, but a turnkey, production-proven grinding process that can immediately run in mass production under controlled tolerance.

Automation Solutions: Integrated and Built Around Your Workpiece

Modern precision manufacturing requires more than tight tolerances. It requires process stability, takt time control, operation capability, and minimal labor.

S-TYPE designs automation around the actual workpiece, real cycle time, and upstream/downstream process requirements — instead of offering a generic loader. Our automation engineering covers the full grinding cell, including loading, positioning, grinding, dressing, gauging, unloading, sorting, and final collection.

The delivered solution includes fixtures, holding strategy, loading/unloading method, dressing logic, size compensation strategy, and process control philosophy.

In other words:
We don’t just ship a centerless grinder into your factory.
We build the grinding cell your factory actually needs.

30+ Years of Experience: Not Just Equipment, but Process Judgment

Over more than 30 years of hands-on grinding, testing, corrective action, and re-validation, S-TYPE has built practical, proven expertise in:

This is why S-TYPE does not simply provide “a base machine plus optional accessories.”

We deliver a complete, production-proven system.
Every mechanism and accessory in that system exists for a reason — to solve a known manufacturing problem, not just to fill a catalog.

Our Position

S-TYPE LTD., Co. specializes in centerless grinding machines and fully integrated automated grinding solutions. Our scope includes long bar grinding systems, infeed / plunge grinding cells, through-feed grinding production lines, dressing systems for CBN and diamond wheels, and turnkey solutions for precision mass production.

Our mission is to transform centerless grinding — traditionally a high-skill, high-barrier process that depends heavily on experienced operators — into a modern, standardized, repeatable, and scalable production platform supported by real measurement data and proven delivery performance.

The question is not how small the tolerance can be one time.
The real question is:
Can you hold that same small tolerance every single day?

This is S-TYPE.
