Roll/Roller Manufacturing Knife Roll (for Knife Coater)
Manufacturing/repair processing of knife rolls for knife coaters used in coating machines, and precision roll manufacturing for cylindrical and vibration μ tables.
The knife roll serves the role of adjusting the amount of coating liquid applied to the substrate in a knife coater, and precision is required at the edge of the blade. There are various types of knife rolls, including the standard type with edge processing done by milling, the adjustment bolt type with a double structure that allows for fine adjustment of edge height using adjustment bolts, and the insert type with a stellite thermal spray applied to the edge. All of these rolls have a very high level of processing difficulty, but Otec has a proven track record in the production and repair of all types of knife rolls. We have numerous achievements in true roundness, cylindrical shape, and runout of less than 3 microns. We also perform repairs on knife rolls with chipped blade coatings. For more details, please contact us. Since the gap between the back roll and the knife roll sets the coating film thickness, high precision in the back roll is also necessary to achieve high-precision coating, including true roundness, cylindrical shape, and runout. Otec also manufactures back rolls in conjunction with knife rolls.
