RAM-TYPE MILLING MACHINE The ram-type milling machine is characterized by a spindle mounted to a movable housing on the column to permit positioning the milling cutter forward or rearward in a horizontal plane. Two popular ram-type milling machines are the universal milling machine and the swivel cutter head ram-type milling machine.

machine is located in a well-lighted and well ventilated area. The floor should be resistant to vibration. 2. To set the machine on a solid concrete foundation, it's advisable to apply a little grout to touch up any unevenness in this concrete in order to get a solid foundation at all points. 3.

Concrete grinders (sometimes called concrete sanders) remove material up to 1/8 of an inch below a concrete surface per pass. Rent a concrete grinder if you need to remove surface materials such as paint, epoxies, stains and other coatings. A concrete scarifier, aka concrete planer or milling machine, removes up to 1/4 of an inch per pass.
