Abstract
CNC machine tools, general transformation of the economy mainly in the rational choice under the premise of numerical control system, and then on the lathe proper mechanical transformation of our existing, and tens of thousands of old, poor machine is a machine overhaul and Numerical transformation of the industry arising from the reality-based China is a developing country, due to its own mechanisms of non-adaptive, low economic strength, technological backwardness, outdated equipment, which greatly restricts the development of the national economy. The long-term operation and even the use of machine overload, while the lack of serious repair and maintenance, resulting in a serious tool wear, loss of precision; a result of new product manufacturing needs, the original machine performance can not meet the application requirements, need to be replaced upgrade. This paper describes the transformation of ordinary lathe CNC design process, a more detailed description of the transformation of ordinary lathe machine part of the design and numerical control parts of the system design. To adopt a 8031 control system for the CPU to process the signal from the I / O interface, the output pulse stepping through a gear reducer, the drive rolling screw rotation, in order to achieve vertical and horizontal movement of the feed.
Keywords: ordinary lathe; numerical transformation; stepper motor; Economical CNC system; CNC tool holder.
