摘要: An improvement to an air logic circuit for an airfeed peck drill includes the insertion of an advance valve into the timer circuit. This advance valve generates a signal to actuate the timer circuit only after the drill quill has fed forward through rapid advance.

摘要: An improvement to an air logic circuit for an airfeed peck drill includes the insertion of a retract valve between the command valve and the air motor. This retract valve generates a required signal to only allow the drill quill to feed forward after it has been fully retracted
摘要翻译: 用于空气啄钻的空气逻辑电路的改进包括在指令阀和气动马达之间插入缩回阀。 该缩回阀产生一个必要的信号,以便只有在钻完成后才能向前进给
