Reamers create tight tolerances

Allied Machine & Engineering Corp. has introduced the S.C.A.M.I. line of ALVAN® expandable precision reamers.

These reamers are offered with carbide, cermet, polycrystalline diamond (PCD), and cubic boron nitride (CBN) cutting edges, in diameters from 0.228 to 7.898 in., and with a variety of lead angles.

The product line also is available in three styles: monobloc, ring, and replaceable head.

The expandable design is used for adjustment due to wear, enabling users to obtain and maintain tighter tolerances. Machinists set their own diameters, helping to ensure a tight tolerance on the diameter. The ring style expands up to 4 per cent of the diameter, while the monobloc and replaceable-head style expand up to 1 per cent of the diameter. The replaceable-head style reamer is available in either expanding or fixed-diameter options.

The monobloc style is suited to smaller-diameter holes. It is more precise than traditional reamers, expands to accommodate for wear, and can be repaired to new condition, the company states.

The replaceable-head option is suitable for a quick setup, because users do not have to remove the tool from the machine and can set up directly on the machine tool.
