Polish master machines are used to finely machine the copper cylinder for a fine surface finish degree. After the cylinder finished its fine machining, it can be installed in engraving machines for patter engraving. The most popular and advanced machines are the Polish master made in Switzerland Daetwyler company.

Polish master tools, are precision diamond tools, which are installed on Polish master machines to process the copper layer on the cylinder. There are generally three cutters allocated in the Polish master machine—— Rough Cutter, Fine Cutter and Side Milling Tool. The rough cutter is used for rough machining copper surface of the cylinder, the fine cutter is used for fine machining and the side milling tool is for profile machining to the end of the cylinder. The common polish master machines are 13# and 21# and their difference is the revolution speed. 13# Polish master machine is low speed and 21# polish master machine is high speed.

Cylinder Preparation Tools Advantages:

We found the possibility to examine the quality of our Polish master cutters to meet the highest technical requirements.

Blade Test

Our Polish master tools are controlled very strictly with our high-resolution optical microscope. Only a perfect straight cutting edge can guarantee the machining quality of rough and fine cutter.

Verticality Test

Place the rough cutter in the measuring apparatus for blade straightness and verticality to the standard axis, this is to guarantee the surface waviness of machined cylinder.

Parallelism Test

Place the fine cutter in the measuring apparatus for blade straightness and parallelism to the standard plane, this is to guarantee the surface waviness of machined cylinder.
