The MIDAS Series includes eight CNC cylindrical
grinders that are designed to meet the rigorous demands and exacting
requirements of high production grinding. The grinders incorporate the
extremely stiff shear damping base design used in Weldon's GOLD models.
Each MIDAS grinder has been uniquely configured with a large grinding
wheel, increased horsepower, a straight or angular wheel-head, GE Fanuc
CNC control, 16" swing, and 12" or 32" between centers capacity. The
models are customized to fit specific applications and are readily
adaptable for factory automation.
