Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z The objection to irregular spacing is that the diameter of the reamer cannot be measured by calipers. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z The small end of the mandrel is thus the standard of its size, and the wear of the collar gauge is in the same direction as that of the reamer. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z Then with a new reamer and new or unworn gauges the hole will be reamed above the standard size to the 1⁄2000 inch allowed for reamer wear.

Fig. Turning and Boring A specialized treatise for machinists, students in the industrial and engineering schools, and apprentices, on turning and boring methods, etc. The operation is to place the reamer into the drilling machine, taking care that it runs true. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z If, however, a reamer have considerable degree of taper, it may be given right-hand flutes, which will assist in feeding it. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z The rose reamer, or rose bit, has its cutting edges on the end only, as shown in Fig. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z Instead of having upon a reamer a flat tooth top to provide clearance, very accurate and smooth work may be produced by letting the back of the tooth, as a in Fig. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z The hole is then finished smooth and to the right diameter by reamer f. Turning and Boring A specialized treatise for machinists, students in the industrial and engineering schools, and apprentices, on turning and boring methods, etc. Obviously the diameter of a reamer reduces as it wears; hence there must be determined a limit to which the reamer may wear before being restored to its original diameter. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z The method employed to grind a reamer is shown in Fig. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z In this case the reamer cannot, by reason of the wear of the cutting edge, ream too small, because the body a forms a gauge of the smallest diameter to which the reamer will cut. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z An adjustable reamer designed and used by the author for holes not less than 11⁄2 inches in diameter, is shown in Fig. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z Sometimes a flat cutter C is used for roughing and a reamer for finishing.

Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z This may be accomplished to a great extent by using two reamers, one for equalizing the diameters of the holes, and the other for the final finishing. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z For reaming the bores of rifles, a square reamer, such as shown in Fig. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z The entering end of the reamer is slightly tapered. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z The reamer is especially desirable for interchangeable work, when all holes must have a smooth finish and be of the same diameter. Turning and Boring A specialized treatise for machinists, students in the industrial and engineering schools, and apprentices, on turning and boring methods, etc. The reamer is revolved at high speed and freely supplied with oil. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z In some forms of reamer the teeth are formed by circular flutes, such as at h in Fig. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z By means of the slips of paper successive cuts and minute increases of diameter may be taken with the same reamer. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z These machines are used for making gauges, reamers, drills, mandrels, taps, and so on. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z When a reamer is held rigidly to a turret or toolslide, it is liable to produce a hole that is either tapering or larger than the reamer diameter. Turning and Boring A specialized treatise for machinists, students in the industrial and engineering schools, and apprentices, on turning and boring methods, etc. With body bound bolts it is customary for machine builders to use a straight reamer to true the hole, then turn the bolt and fit it into its place. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z It is obvious that a reamer must, to produce parallel holes, be held axially true with the holes, or else be given liberty to adjust itself true. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z That reamer is intended to produce a straight hole, but having once passed through a hole the reamer will be slightly worn. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z There have been many attempts made to produce a reamer that should be adjustable. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z To prevent this, the reamer should be held in a “floating” holder which, by means of a slight adjustment, allows the reamer to align itself with the hole. Turning and Boring A specialized treatise for machinists, students in the industrial and engineering schools, and apprentices, on turning and boring methods, etc. But the successful use of a reamer of this kind depends upon the drill that precedes this reamer being made as nearly right as possible, so that the reamer will have little work to do. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z For short holes the shell reamer shown in Fig. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z The less you give a reamer to do the longer it will maintain its size. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z It follows that the tapered reamer would be nearest right which would also take out the least amount of metal. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z The tool shown at B is a four-lipped drill which is used for drilling cored holes preparatory to finishing by a cutter or reamer. Turning and Boring A specialized treatise for machinists, students in the industrial and engineering schools, and apprentices, on turning and boring methods, etc. Suppose, then, one spindle to drive a drill, the second driving an enlarging drill, a third driving a countersink, and a fourth a reamer. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z If there are a number of lathes in a shop, each lathe may have its own bracket b, all these brackets being bored to receive the same bushes, and therefore the same boring-bars or reamers. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z The reamer thus carries the die with it, the slot in the false face acting as a guide to the die. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z If, however, the side exerting the most pressure upon the reamer is always made the one forcing the cutter back, as shown in Fig. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z This drill would probably finish a hole to within about 1/32 inch of the finish diameter, thus leaving a small amount of metal for the reamer to remove. Turning and Boring A specialized treatise for machinists, students in the industrial and engineering schools, and apprentices, on turning and boring methods, etc. For finishing the walls of holes more true, smooth, and straight, and of more uniform diameter than it is found possible to produce them with a drill, the reamer, or rymer, is employed. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z It is obvious that such a reamer, however, does not produce strictly a cone countersink, as is shown in Fig. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z It is obvious that in this form the reamer is expanded most at the end. Modern Machine-Shop Practice, Volumes I and II 2012-03-23T02:00:33.140Z In this way the hole is reamed straight and to practically the same size as the reamer. Turning and Boring A specialized treatise for machinists, students in the industrial and engineering schools, and apprentices, on turning and boring methods, etc. Floating Reamer Holders.—If a reamer is held rigidly in the turret of a boring mill or turret lathe, it is liable to produce a hole which tapers slightly or is too large. Turning and Boring A specialized treatise for machinists, students in the industrial and engineering schools, and apprentices, on turning and boring methods, etc. The reamer and holder shown to the left has a ball-shank A which bears against a backing-up screw B inserted in the end of holder C through which the driving pin passes.
