Engraving machine table structure
The engraving machine table has more than one slot on the plane plate, and the platen screws for clamping and positioning can be arranged in the slot. Since the flat plate of the workbench is provided with a groove, the circuit board can be disposed on the workbench through the platen screw, and the double-sided adhesive or adhesive is not required on the back surface, thereby ensuring the flatness of the surface of the circuit board.
Material: The material is high-strength cast iron HT200-250 working surface hardness is HB160-210. After two treatments (artificial annealing 600----700 and natural aging for 2---3 years, the precision of the product is stable and the wear resistance is good.
Cast iron casting, because graphite in cast iron is good for lubrication and oil storage, so wear resistance is good.
