The Nock Cortex CB435 is an automatic/manual derinding machine (upgrade model for Cortex CB 430, now with longer in-feed conveyor belt), particularly compact and good value conveyorized derinding machine. Automatic derinding of all pieces, for example belly, back fat, rind cut to size, partial cuts etc. “Manual” derinding of round pieces, for example ham or shoulder, with open top, makes the Nock Cortex CB435 a cost effective option within any production line. The Nock Cortex CB435 has a cutting speed: 24 m/min.

Highly strained parts of a derinding machine are positioned on the casing, sooner or later it can come to deformation or crevices. With a 15 mm thickness, the NOCK POWER PLATES® are resistant to material fatigue. This has been proven by thousands of NOCK machines since 1990 in the hardest industrial operation, even in several shift operation.
