Rack is an indispensable part of CNC machine tool, it plays a very important role in lathe machining.Lathe rack is combined with the gear mechanism inside the lathe feeding box to form the speed of the movement transmission of the sliding board box in the lathe part to move forward and backward, according to the basic process of the part process design, through comparison and demonstration, the practical choice is made

The correct route, in the process of rack manufacture process design, process analysis was carried out on the rack first, such as the structure and characteristics of rack, rack and choice of blank, the selection of processing equipment, the formulating process benchmark, the choice of process route, process should pay attention to the problems in the preparation and processing, the second is based on process analysis of the machining process of rack.
