RKS SM 1100 AL

RKS Squeegee grinding machines.

For over a quarter century RK Siebdrucktechnik GmbH has been developing and  manufacturing grinding machines, not only for the printing industry.

With more than three hundred machines sold in throughout the printing industry, we are among the leading providers of squeegee grinding machines, worldwide.


Our aim was and is to produce squeegee grinding machines allowing, efficient, fast, affordable, user-friendly, and reproducible ground squeegees for  screen printing.



Every day "hundreds of meters of" of RKS squeegee are sent to our international and domestic customers.

Connected with this the grinding the plane-parallel defined homogeneous  “printing edge” of the polyurethane is achieve.

To our knowledge we are the only manufacturer of squeegee grinding machines worldwide, that process daily such a variety of screen printing squeegees that are shipped "ready to print".

In our own interest, our engineers and designers are always researching for new  and more effective ways to rework screen printing squeegees.

Owing to our more than twenty-five years of experience in the field of "squeegee reworking" one thing is sure:


At this moment in time there is for us no more a precise, more economical and qualitatively comparable alternative to squeegee blade grinding.

Really automatically grind

This requirement is only met by the RKS Squeegee Grinder with laser positioning on the market.

The operator inserts the squeegee, clamps it and selects a grinding program.

The grinding process is then automatic, avoiding possible operator errors such as too large an advance.

The RKS Squeegee Grinder with laser positioning combines all proven and known advantages of the RKS Squeegee Grinders.
