Horizontal Boring Mills

The MB series of Conventional Table Type Horizontal Boring Mills are used to mill, drill, bore, face, groove, etc. in all types of steel and alloy parts. These machines are constructed of 100% heavy duty cast iron for superior vibration damping and cutting accuracy. They feature a built-in rotary table for machining four sides of a complex part in a single set up. They also have a built-in facing head for expanded functionality without adding cumbersome attachments. The machines have Newall DRO's installed on the X, Y and Z axes for highly accurate machining. A heavy duty outboard support is optional for completing highly accurate line boring.
