Description

Grinding device is carried to brake disc psammitolite Technical Field The application relates to the field of brake disc production and manufacturing technical equipment, in particular to a brake disc sand core conveying and polishing device. Background The manufacture of brake discs mainly comprises casting, machining and other procedures. In the casting step, molten iron is melted by a smelting furnace, a sand core forming an air channel is manufactured by a core shooter, a sand mold is manufactured by a molding machine, and finally the molten iron is poured into the sand mold containing the sand core by a casting machine, so that a brake disc blank is formed. In the machining stage, the friction surfaces at two sides are finished by using a numerical control lathe, so that flatness and thickness are ensured, bolt holes on a mounting surface are machined through a vertical machining center, and finally marking and delivery are finished through a quality inspection process.
