Product Introduction

Welcome to use the Model M2630S-K2 CNC Pelletizer Hob Relief Grinding Machine manufactured by Nanjing Weigao. This machine is designed for relieving the rake face of indexing tools such as straight-fluted hobs and form cutters, which are used in pelletizers.

This model features a self-developed 2-axis CNC system with a Chinese interface. The entire relieving process is controlled by servo motors. The machine adopts variable programming, allowing users to edit, store, and recall relieving programs for different tools. Operators only need to input corresponding variable data and working parameters to start a fully automatic grinding cycle. The operation is extremely simple, practical, and easy to learn, making it accessible for ordinary workers to operate proficiently.
