High Speed C Flute Corrugated Roller Tungsten Carbide Steam Heating

Rigorous for Precise Grinding

After heat treatment and the cutting slots, the roller shall be put on high precision automatic CNC grinding machine to do finish grinding. Almost every set of corrugating rolls are needed to be designed and customized separately according to the width, diameter, flute height, corrugated paper GSM, speed and cardboard physical index requirement. The designed flute profile is copied on a costly diamond tool. When grinding wheel and diamond tool touch together, the flute profile is dressed on grinding wheel. By grinding wheel grind each flute several times until the accuracy is within our technical permitted requirement. The Siemens control system play a key role in guarantee the accuracy.

Repeatedly Polished, Smooth As a Mirror

Meijia adopts special polishing crafts, such as the corrugated rollers use America Praxair 1342VM series super hard tungsten carbide roller, special customized polishing wheel. With our company’s fully automatic CNC corrugated roller producing process’s special polishing machine and our independent grinding polishing technology R&D, the tungsten carbide roller’ s surface finish degree can reach Ra<0.6μm, which will improve the accuracy of the flute profile, and make sure the quality of the corrugated roller.
