Automatic duplex deburring tool - ADCT

Automatic deburring tools

Normally, the bottom side of a drilled hole is deburred or chamfered, after mounting the same job upside down. The automatic duplex deburring & chamfering tool, in one go, deburrs and produces a chamfer in a drilled hole both at the top as well as at the bottom. No change either in the spindle speed or in the direction of spindle rotation or in the job set-up is required. The tool can be deployed immediately after drilling. Neither manual interruption nor special operational skills are required at any stage of its use

The duplex deburring & chamfering tool is offered for hole dia 5 mm to dia 22 mm. These tools are meant for deburring and creating a light chamfer around the bore. For heavy chamfers and for bore dia 23 mm and above, we recommend the Automatic Duplex Back Chamfering Tool. Two triangular inserts are mounted on the wing – one for top chamfering and the other for bottom chamfering. In the anti-clock wise rotation, the tool enters the bore; in clockwise rotation, the wing opens up due to centrifugal force and chamfers. Pull the tool upward for top chamfering and push the tool down for back chamfering. Again in the anti-clockwise rotation, pull the tool gently out of the bore, as wing retracts into the pocket. The carbide inserts are standard, centre clamping type. tool enters the bore; in clockwise rotation, the wing opens up due to centrifugal force and chamfers.

On finishing the drilling operation, remove the drill and mount the chamfering tool to the machine spindle. Using the same clock-wise spindle rotation and speed, which you have used for drilling, just pass the tool through the drilled hole. As the tool enters the drilled hole, it removes all the burrs from the top of the hole and produces a light chamfer around the hole; the blade slowly retracts inside the pocket, provided in the tool shank, as the cutting pressure increases. The blade gets slowly released from the pocket as the cutting pressure decreases. On blade clearing the hole, withdraw the tool without changing the spindle speed or direction rotation. When the tool retracts, it removes the burr from the bottom and produces a chamfer around the hole. The chamfers are uniform and concentric, since the tool is always guided through the bore.
