<p>A concrete cutting machine for making parallel precision linear cuts to repair a joint (18) in a concrete floor (19). A self-propelled vehicle (9) follows a linear track segment (10, 11) accurately positioned with respect to the path of a linear cut to be made in the concrete floor. A carriage (12) supported by the vehicle (9) is vertically positionable with respect to the floor and a table (89) supported by the carriage (12) is horizontally positionable with respect to the vehicle (9). A cutting blade (60) and motor drive (99) are supported by the table (89), permitting the blade (60) to be accurately positioned relative to the joint (18). The cutting blade (60) is enclosed within an enclosure (25), and may be immersed continuously in a recirculated coolant (30) during cutting of the concrete floor (19).</p> |
