Additional replaceable head reamers for high-production machining now offered.

Allied Machine and Engineering, a leading manufacturer of holemaking and finishing cutting tools for the metal-cutting industry, announces the expansion of ALVAN reaming products by SCAMI with the 5000 series and 9000 series reamers. These replaceable head reamers offer a solution for high-production environments, industries such as automotive, heavy equipment, agriculture, firearms, and hydraulics, where tight tolerances and extreme surface finishes are required. With carbide and cermet grades as well as multiple coatings and geometries, these two series of ALVAN reamers are ideal for applications in all materials.

The 9000 series ALVAN reamers are ideal for extremely high-production hole finishing applications where optimal surface finish, tool life and penetration rates are required. The quick-change (throw away) design provides reduced downtime for assembling and indexing new heads. Other features of the 9000 series include:

-Diameter range: 11.80 millimeters - 40.60 millimeters.
-Capable of H7 hole tolerances.
-Available with modular and cylindrical shanks—short and long length.
-Sintered carbide/cermet design allows for potential increased tool life/penetration rates.
-Heads are finish ground to the desired diameter at SCAMI.
-Quick-change connection between the head and mandrel for reduced machine downtime in high-production settings.

The 5000 series ALVAN reamers excel in applications with holes requiring extremely tight tolerances where minimizing operator intervention is critical. Setting up reamers and achieving optimal results often requires a high level of operator skill level, but with the 5000 series, the diameter setting is done by SCAMI prior to shipment, making it ready to use as soon as it is received. It also allows for quicker tool changes when the head is worn and needs to be replaced with a new one. Other features of the 5000 series include:

-Diameter range: 9.60 millimeters - 32.60 millimeters.
-Expandable diameter capabilities for wear compensation.
-Available with modular and cylindrical shanks—short and long length.
-Highly repeatable twist-locking design of the head onto the mandrel for reduced machine downtime between head changes.
-Excellent TIR repeatability from head-to-head changes.

Natalie Givler, product manager of the hole finishing product lines at Allied Machine shares that "With high-production tools like reamers, minimizing machine downtime is critical. These additional ALVAN reaming products by SCAMI provide an easy-to-use assembly method, which simplifies the setup process and lowers the risk of scrapped parts."
