Hand Reamers - 2: Reaming Procedure
|WARNING: Machine tools present a safety hazard. Improper operation can result in severe injury. These topics are for non-laboratory study only and are not to be used in conjunction with the operation of any tool or machine described herein. Never use a machine tool without the supervision of a qualified instructor.|
|Step 1: Get a tap wrench or T-handle wrench and a hand reamer
Step 2: Attach the wrench to the squared end of the reamer
Step 3: Ensure perpendicularity between work and reamer with a square. As an alternate method you can use a reaming guide or a spring loaded center guide.
Step 4: Evenly turn the reamer in the hole to ensure alignment with the hole. (The bevel on the end of the reamer will help.) A rule of thumb for feeding rate is one quarter of the reamers diameter per revolution. Never rotate the reamer backwards as you would in a tapping operation as this would dull the reamer quickly.
Step 5: Ideally pass the hand reamer through the hole, if not possible, remove the reamer from the top by continuing the rotating motion.
