CNC arbors allow the use of open bore cutters on a CNC machine. These cutters are typically only used on molders, shapers and other shaft spindle machines. The cutters that can be mounted on these arbors are typically larger in diameter. Our arbors have a variety of shaft diameters and lengths. Our arbors are balanced to 24,000 RPM at G2.5. Arbors can be used for edge machining, rebates, and side profiling on a 3 axis machine. On a 5 axis machine the possibilities are quite large and limited only by the programmer and the tooling mounted on the arbor. If you have any questions please reach out through phone or email.
