This machine can realize automatic feeding, automatic cleaning and automatic unloading of workpieces, and the whole working process is automated. Reduce labor intensity and improve production efficiency. The crawler shot blasting machine is suitable for small castings, forgings, stamping parts, springs and other parts, and heat treatment workshops to clean thin walls, sticky sand, oxide skin and other attachments on the surface of parts that are afraid of collision, etc., and can also be used for surface strengthening treatment of some parts. (High temperature parts cannot be directly cleaned, with burrs, flying edges, or otherwise vulnerable tracks) This machine can realize automatic feeding, automatic cleaning and automatic feeding of workpieces.
