Drilling and boring units, which include a hydraulic motor and anchoring mechanism, are used to attach the cutting machine. The schemes of water supply of the machine tool are analyzed and a rational variant is selected. The disadvantages of the known water motors are disclosed and the ways of their improvement are suggested. Recommendations on calculation of the parameters of the hydraulic motor, on the design of the anchoring mechanism and its calculation are developed. The result on the efficiency of light cutting machine with a new way of fixing its time is obtained.
