MK-400
High-Precision CNC Insert Grinder for Carbide, Cermet, Ceramics, CBN & PCD Indexable Inserts
The MK-400PLUS is a high-precision CNC grinding machine specifically engineered for the efficient and repeatable production of indexable inserts made from ultra-hard materials, including carbide, cermet, ceramics, CBN, and PCD. Designed for maximum flexibility, performance, and accuracy, this model is ideal for both mass production and small-batch customized insert grinding.
Whether you're manufacturing standard ISO inserts or complex custom geometries, the MK-400PLUS ensures superior surface finish, excellent form accuracy, and reliable repeatability — making it an essential solution for cutting tool manufacturers and resharpening services.
