The machine uses resin disc and tilting disc, because resin disc is light in weight, small in consumed power, and high in grinding efficiency; its price is only 1/2 of traditional continuous grinding and polishing machine of the same specification; the power needed by the grinding disc is 7.5KW, which is only 1/3～2/3 of grinding head for ordinary grinding machine of the same specification, with low power consumption. 
The machine is multi-point continuous board-incoming production, with high efficiency and low labor cost. Production efficiency of a set of equipment may be that of several walking or bridge-type grinding and polishing machine, and only 2～4 workers are needed. As for the machine, air pressure controls lifting and falling of grinding disc and pressuring range is adjustable; oscillating beams can drive grinding disc for moving and movement speed is adjustable; belt of belt-type board-sending workbench can is adjustable; electrical system adopts PLC and human-computer interface.
