Federal Broach & Machine L.L.C. has been in business since 1952. our broach machines have been operating in customer plants since 1971. all machines, fixtures, broach holders and broaches are designed on cad. cad-cam and cad-cae are used throughout our manufacturing processes to ensure quality products reach our customers.

Federal Broach & Machine L.L.C. is committed to continuous quality improvement in all our products. reliability, maintainability and durability is foremost in our thoughts during design and manufacture of broach products. our broach machine lineup is constantly being upgraded to improve machine performance.

In climb milling, the direction of cutter rotation and the direction of workpiece feed are the same. The initial portion of the chip generated is thick and gradually thins through the cutting cycle, producing a better finish. The maximum cutting force is the initial downward thrust at the beginning of the cutting cycle.

ARBOR DIAMETER: Select the largest diameter available to maximize rigidity and minimize deflection. For example, a 1 1/4″ arbor is more than twice as rigid as a 1″ arbor.

TYPES OF MILLING: In conventional milling, the direction of cutter rotation is opposite to the direction of workpiece feed. The initial portion of the chip generated is very thin and gradually increases through the cutting cycle. The maximum cutting force is upward at the end of the cutting cycle.

APPROPRIATE: carbide grade, carbide finish, number of teeth, flute size, radial rake angle and cutting edge clearance are engineered by HANNIBAL for optimum performance when machining the materials indicated.

For slot and side milling cutters, select the diameter which permits no more than two teeth to be engaged in the cut at any time.

NUMBER OF TEETH: Select fewer teeth for low tensile materials and heavier chip loads. Select more teeth for high tensile materials and better finishes.

Federal Broach & Machine L.L.C. is located in Harrison in central Michigan. we are close to the intersection of u.s. 10 and u.s. 27 and are about a 60 minute drive from the mbs (midland, bay city, saginaw) international airport.

Federal Broach & Machine L.L.C. is a privately held corporation serving the auto, large truck, farm and defense industries. our 86,000 square feet of manufacturing space are modern, clean and feature current c.n.c. technology.

TOOL DIAMETER: For slitting saws, select the smallest diameter which permits the greatest number of teeth to be engaged in the cut at any time.
