REAMING | ALVAN® Reaming Systems by S.C.A.M.I. | Cuƫng Ring Reamers

Setup InformaƟon

Drive Pin (11:00 posiƟon)

Dimples (12:00 posiƟon)

Step 1: With the drive pins assembled, insert the cuƫng ring onto the mandrel. Make sure the dimples are at the 12:00 posiƟon with the drive pin at the 11:00 posiƟon.

Adjustment Procedure 1. Turn the conical ring slowly using an adjustment key (leŌ-hand thread). Adjustment keys are supplied with reamers from diameter 17.600 mm to 40.599 mm. 2. Check the diameter seƫng of the cuƫng ring with a micrometer. 3. When the required diameter is achieved, unscrew the conical ring unƟl there is a click and the drive pins are in tracƟon in the opposite direcƟon to the cuƫng acƟon of the reamer. The reamer is ready for use.

Step 2: Insert the conical ring. Tighten the lock nut to set the desired reamer size (leŌ-hand thread). Then loosen the lock nut slightly unƟl it “clicks” against the drive wall. NOTE: We recommend lubricaƟng the thread and the conical surface of contact between the cuƫng ring and the conical ring with anƟfricƟon MOLYKOTE® grease. Through Hole

Assembly 1. With the drive pins (2) assembled, mount the flange (1) onto the mandrel. Assemble the cuƫng ring (3) so the slot on the leŌ side of the dimple is mounted onto the drive pins (2). Insert the conical ring (4). 2. Screw the ring nut (5) onto the mandrel and Ɵghten manually so the conical ring (4) makes contact with the cuƫng ring (3). The thread is leŌ-handed. NOTE: We recommend lubricaƟng the thread and the conical surface of contact between the cuƫng ring and the conical ring with anƟfricƟon MOLYKOTE® grease.

Adjustment Procedure 1. Turn the ring nut (5) slowly using a pin spanner. 2. Check the diameter seƫng of the cuƫng ring with a micrometer. Make sure the drive pins (2) are in tracƟon and in the opposite direcƟon of the cuƫng acƟon of the reamer. 3. When the required diameter is achieved, the tool is ready to use.
