In the block machine, the concrete is forced downward into molds. the molds consist of an outer mold box containing several mold liners.
sandblasting is a process in which sand, glass beads or some other medium is shot at high speed through a machine across the surface of a hard material until it is sanded smooth. sandblasting is often done to remove a previous finish on an item, to remove rust, or to prepare a surface to receive a new coat of paint. the kind of medium used to blast the surface depends on how difficult the the planner milling machine is mostly used for facing operations in mass production. these machines are similar to the bed type mill machine, except it can be mounted with various cutters and spindle heads to the machine. these cutters in the machines can perform the facing operations simultaneously which is a great function. special milling
