精品- 可编辑 - English Translation Material 1. Transfer MachineThe highest degree of automation with special-purpose, multifunction machines is achieved by using transfer machines. Transfer machine are essentially a combination of individual workstations arranged in the required sequence, connected by work transfer devices, and integrated with interlocked controls. Workplaces are automatically transferred between the stations, which are equipped with horizontal, vertical, or angular units to perform machining , gaging ,workplace repositioning, assembling, washing, or other operation. The two major classes of transfer machines are rotary and in-line types.An important advantage of transfer machines is that they permit the maximum number of operations to be performed simultaneously. There is relatively no limitation on the number of workplace surface or planes that can be machined, since devices can be interposed in transfer machines at practically any point for inverting, rotating, or orienting the workplace, so as to complete the machining operations. Work repositioning also minimizes the need for angular machining heads and allows operations to be performed in optimum time. Complete 精品- 可编辑 - processing from rough casting or forging to finished parts is often possible.One or more finished parts are produced on a transfer machine with each index of the transfer system that moves the parts from stations to stations. Production efficiencies of such machines generally range from 50% for a machine variety of different parts to 85% for a machine producing one part, in high production, depending upon the workplace and how the machine is operated(material handling method, maintenance procedures, etc. )All types of ma...
