Tuckwell Machinery supplies Australia’s leading circular knife grinders for paper converting, packaging, plastics, meat processing and textile cutting operations. The MVM-Businaro CK 500 and CK 300 TH are high-precision, technician-approved machines engineered for sharpening circular knives, bottom knives and slitter blades with exceptional accuracy, speed and consistency.
Whether you need to sharpen slitter blades in-house, improve cutting quality on your production line, or reduce downtime caused by dull knives, these machines deliver reliable, repeatable performance backed by full Australian support.
Circular knives without teeth are used across a wide range of industries. These machines are designed specifically for:
