A plate rider is a pneumatically controlled dish with a number of roller balls mounted in the base. The dish is retracted whilst the machine is traversing but when cutting the dish is lowered so the balls are in contact with the material. The torch is positioned a precise height above the bottom of the balls and an exact torch stand-off is maintained in this manner. The plate-rider is a very simple device but produces excellent results on materials up to about 6mm. Because of the contact between the balls and the material, the plate rider is not always suitable for particularly highly finished materials.
