About us

GRT-Tech is a relatively young company that carries many years of experience. Through work experience, innovation, and development, the name GRT-Tech has become synonymous in our industry. With the many possibilities we offer, we help improve product innovation.

The best techniques for your product.

Expertise

Cylindrical Grinding and O-grinding

Cylindrical Grinding and O-grinding

From non-ferrous to hardened steel. Internal and external grinding to the correct tolerance. We can also meet requested roughness requirements. With this precision grinding technique, we go beyond CNC turning and CNC milling.

Surface Grinding

Surface Grinding

Creating a complete product or just surface grinding/profiling after hardening? Material allowance for grinding your product? Ask for our advice; based on your drawing, we will examine the possibilities. Tolerance up to at least 0.002mm. At GRT Tech, we can do more than you expect.

Honing

Honing

From hard metal and non-ferrous metal to cast iron. This machining technique ensures dimensional accuracy, cylindricity, and desired roughness. With diamond and cubic boron nitride honing stones, we efficiently remove material allowances.

3D Measurement

3D Measurement

Need a measurement report for independent measurement, internal control, or certification for your customer? We provide your product with a measurement results report from our 3D Zeiss machine. Zeiss measurement capabilities are all-round, covering form and positional tolerances, flatness, cylindrical and elliptical scans.
