Upgrading of the Bench Drilling Machine's Manual Feeding to Automatic Feeding System

摘要

Bench drilling machine is compact and flexible. But in the mass production, as the feeding of the machine is rely on manual work, the workers are easily to be exhausted and the manual production is not effective. This thesis gives a brief introduction of process of designing the automatic feeding device which is based on PLC for the Z512-drilling machine. The thesis demonstrates the device's construction and control logic. This device can save works' labor, time, easily to be produced and has a valuable application.
