\n\t\tFinishing By Grinding\t<\/h2>\n\t\t\t

To produce high quality boards with maximum speed, the flute profile should be accurately ground, and the surface should be completely smooth. Our unique \"Finishing by Grinding\" procedure ensures an accurate flute profile as designed with unform coating thickness. The coating surface is also as smooth as a chrome plated surface(Ra is less than 0.2um).<\/p><\/div>\n\t<\/div>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\tHardening\t<\/h2>\n\t\t\t

In order to build durable corrugating rolls it is important to increase surface hardness while keeping the roll less brittle. Most common method to increase the hardness of raw material is high frequency induction hardening after flute forming. Although this method is easier and cheaper, it has disadvantages \u2013 shallow hardened layer with uneven hardness distribution. Thereby the rolls are brittle.<\/p>

SRC takes different approach to build more durable rolls. We do low frequency induction hardening for deeper hardened layer with uniform hardness distribution. In addition the raw material is hardened before flute forming to reduce cracks or break-up of flutes.<\/p><\/div>\n\t<\/div>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
