1. Precision Welding Can Be Inseparable

Both ends of the roller body should be heated to release the size of the inner bored hole. After the spindle heads are put in, the roller body and the spindle heads should be held tightly after natural cooling. When everything is ready, a driving fit interface has been formed between the roller body and the spindle heads by means of preheating, welding or bolting. When the welding process finished, the work piece shall be put into the furnace for high temperature tempering to reduce stress.

2.High Hardness from Vertical Quenching Process

Intermediate frequency quenching can guarantee both the hardness and harden depth we need. Our harden layer depth can reach to 8-12mm. With harder base material as foundation, the lifetime of our corrugating rolls are greatly extended. After different heat treatment process, the corrugated roller surface becomes more wear-resistant and durable. After heating treatment we cut slots of lower roll though this process needs more time but makes uniform hardness.

3. 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. 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.
