PERFECT high precision surface grinders use high quality cast iron to ensure rigidity and stabilized accuracy. P4 precision angular contact bearings are used for the spindle to ensure tight roundness accuracy, and the completely sealed and lubricated cartridge design enhances the machine design's high durability and accuracy.
The M series use AA grade steel balls for the guide ways to make operation easier and lighter.
The H series use turcite coated slide ways for stability and durability.
