Like what you read on CNCCookbook? Use a Right Hand Spiral Reamer with Center Fed Coolant to maximize chip clearing, especially in highly ductile materials. The greater the taper, the worse these conditions will become. The spiral will help bridge the gap so the reamer is supported at all times. Opinions vary on exactly what that rule of thumb ought to be for reamer speeds and feeds. Most reaming machines are essentially chucks mounted on the output shaft of a motor-driven gear reducer. In cases where there is a large quantity of light parts to be reamed, the reamer is often mounted horizontally in a reaming machine. Too low a feed may "glaze" the hole, which has the result of work hardening the material, causing occasional chatter and excessive wear on the reamer. The chip load depends on the characteristics of the tool and the workpiece material. The same problem arises if work is reamed on a table press without a bushing. Besides varying in function and design, these different floating holders also vary in their inherent rigidity. For most applications, however, CNC and manual machinists will use either a Machine reamer or a Chucking reamer, in that order.

For all else, carbide-tipped, modular, or solid carbide tools are preferred. It is particularly important when using bushings that the spindle be accurately aligned with the bushing in order to prevent the reamer from hitting the top of the hardened bushing. As drill sizes vary in increments of 1/64", it is found that theoretically 1/64" has been left for reaming, but in fact it is only 0. Carbide-tipped Annular Cutter Speed.

For machine reaming, it has been found that a reamer having few flutes, and with cutting edges at a large spiral angle with the axis, is by far the best. Indexable Turning Toolholder Nomenclature. Rigidity also maintains surface-finish quality, avoiding the marks made by elastic vibration and free play of loose fits and backlash.

Controlling Tool Wear and Failure. Provision must be made for guiding the reamer bar or arbor at both ends. It should be remembered that high-spiral Taper Reamers cannot be used on hand operations because of the end pressure required, but for machine operations this is by far outweighed by smoothness of operation, better quality of work, and longer reamer life. Sergeant Major Basil L. Plumley, Ia Drang Valley. Occasionally the designer is confronted with the task of supplying a reamer for straightening holes that have run off from the true center line owing to irregularities in the subject piece, uneven conditions in the metal, or plain carelessness in the shop.

Use a floating holder if necessary. For an operation such as milling, the slower the feed rate (and cutting speed), the smoother the finish on the workpiece will be. These grooves serve the double purpose of permitting the cutting fluid to lubricate the pilots and to scavenge any chips that tend to wedge between the pilots and bushings. Reamers with adapters for quick-change chucks are used on production set-ups. When the errors are not too great, the job can be saved by substituting an end-cutting reamer for one with the conventional chamfer. There are two principles that must be embodied in satisfactory floating reamer drivers. Broken or uneven spacing is carefully planned to occur according to prescribed rules set down by the individual manufacturer to meet his own requirements. These reamers can use replaceable inserts and they are often expandable to adapt to tool wear.
Leaving too much material behind will lead to chip packing and possible tool breakage, while too little causes the reamer to rub rather than cut, resulting in poor tool life and surface quality. A straight flute reamer will bang like crazy as every tooth catches on the interrupted edge. Clearance, chamfer relief, and rake angles must be specified to suit the work to be done. The use of bushings as guides for reamers is of great help. A milling cutter at slow feed may actually rub until pressure builds up. Quote Link to comment Share on other sites.
