Based on PALMARY's tradition of "Pursuing Quality Perfection", combined with human engineering design and peak performance concepts, each machine fully reflects PALMARY's unmatched design and technique.
The machine bed is manufactured from high-quality Meehanite cast iron, heat treated and stress relieved for outstanding stability and without deformaiton.
CNC controllerThe Mitsubishi M70 controller with a user-friendly control panel frame that allows operator to easily choose different grinding modes for arranging grinding program. FANUC controller is optional.
High grinding accuracyNo Vibration and run-out caused by self-weights of the workpieces and chucks that may affect grinding accuracy.
Easy chuckIrregularly shaped workpieces are easy to chuck.
Auto. tool change system (ATC)Equipped with max. 6 no. grinding wheels for different diameter or accuracy requirement.
