Drilling Cum Tapping Machine For Industrial

In drilling cum tapping machine tapping or threading operation is done along with drilling. This tap drill machine is most suitable in areas where operator needs to perform drilling and tapping operations without opening the job such as using a quick change chuck. The tapping attachment of the machine tap is fitted on the motor plate that is fixed on the machine body. The tap when completes the desired depth is reversed automatically by the limit switch. The electrical panel on the electrical tapping machine has a toggle switch with options of limit control and foot control. When the universal tapping machine does tapping for a blind hole, then move the toggle switch upwards to ‘limit control’ and set the depth with two small stoppers fitted on the main rod. For the semi automatic tapping machine to tap a through hole, then move the toggle switch to ‘foot control’ option and complete the tapping using the foot switch. Here the stoppers and limit switch is not used. The tapping operation on these vertical tapping machines starts by engaging the tap to the hole and the tapping tool itself takes its own movement to complete the depth of thread. So no effort is needed during the tapping cycle.
