Allied Machine & Engineering Corp, a manufacturer of holemaking and finishing tooling systems, offers a complete range of ALVAN expandable precision reamers, a suitable tool for high volume production. The ALVAN line is available through an exclusive supply agreement with S.C.A.M.I., an Italy-based maker of precision reamers. Allied has a large team of in-house application engineers to help select the right product for specific applications, and can customize their reamers through a variety of geometries, substrates, and coatings.
The ALVAN reamers are a good choice where high precision is needed, like those used in such gun manufacturing applications as gun barrels, receivers, and site mounts. The reamers are also widely used in aerospace, where they offer the right geometry for use on composites and high-temperature alloys.
Offered with carbide, cermet, polycrystalline diamond (PCD), and cubic boron nitride (CBN) cutting edges, the reamers come in diameter sizes from 0.228 to 7.898-in. (5.8 to 200.6mm). With a wide variety of different lead angles, the ALVAN line helps customers achieve the best finish for the material they are machining.
The ALVAN expandable reamer product line is available in three styles: monobloc, ring, and replaceable head. The expandable design is used for adjustment due to wear, allowing users to obtain and maintain tighter tolerances. Customers set their own diameters, helping to ensure a good, tight tolerance on the diameter. The ring style expands up to 4%t of the diameter, while the monobloc and replaceable head style expands up to 1% of the diameter. The replaceable head style reamer is available in either expanding or fixed diameter options.
In addition to producing close tolerances and dimensional accuracy of machined holes, the ring and monobloc styles provide a lower cost per hole with their high penetration rates, making them an suitable choice for finishing holes in a production environment. Compared to traditional reamers, the ring-style reamers are ideal for large diameter holes by preventing the need to replace a large solid reamer, reducing waste. The monobloc styles, are directly suited to smaller diameter holes. They are more precise than traditional reamers, expand to accommodate for wear, and can be repaired to new condition.
The replaceable head option can be used 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. This option is a good choice for use with the fixed head reamer, in which the diameter comes preset and ready for use. With this option, users get the benefits of a high precision tool without the need to expend time on set up.
A full application engineering support team is available to help customers choose among available options, based on the application, the diameter of the hole, and the production environment. Allied also offers fast delivery times and superior field service support.
