A concrete cutting machine for making parallel precision linear cuts to repair a joint in a concrete floor. A self-propelled vehicle follows a linear track segment accurately positioned with respect to the path of a linear cut to be made in the concrete floor. A carriage supported by the vehicle is vertically positionable with respect to the floor and a table supported by the carriage is horizontally positionable with respect to the vehicle. A cutting blade and motor drive are supported by the table, permitting the blade to be accurately positioned relative to the joint. The cutting blade is enclosed within an enclosure, and may be immersed continuously in a recirculated coolant during cutting of the concrete floor.
