Slitting Equipment



IRM Model 17518 High Production Precision Slitter

The IRM Model 17518 High Production Precision Slitter has a 1 3/4" diameter with .250" keyway x 18" long arbor. This item includes an entry guiding system and exiting table. General machinery specifications with explicit notes to follow:

One IRM Model 17518 precision slitter is capable of slitting a width of up to 18" wide strip. The slitter is equipped with two parallel hardened slitting arbors exactly 1.750" in diameter with .250" square keys (the entire usable length). These shafts are heat-treated, hardened and finish ground within .0001" T.I.R.

Note: Arbor length will be 19" long. It will have 3/4" high shoulders with 1/4" undercut.

The bottom shaft is fixed and the upper shaft will be mounted in a precision "eccentric bearing" and bushings housing. The total offset eccentric of the upper shaft is .375 " exactly at the inner and outboard mountings. The theoretical centerline is to be 3.625.

The outboard bearing/shaft housing will be precision machined and center-keyed onto the mill top plate.

Note: This machine can be tailored to the customer's specifications.

The machine is powered by a 3HP DC motor to deliver the speed of approximately 160 Fpm.

Machinery Guarantee: One year of parts and labor or if machine is proven to have a defect within 18 months from date of shipment.




I.R.M. Model 2009

2" diameter with 3/4" keyway x 9" long arbor. This will include an entry guiding system and pass line roller assembly with pinion stand. General machinery specifications with explicit notes to follow:

The IRM Model 2009 precision slitter is capable of slitting a width of up to 7" wide strip. The slitter is equipped with two parallel hardened slitting arbors exactly 2.000" in diameter with .250"square keys (the entire usable length). These shafts are heat-treated, hardened and finish ground within .0001" T.I.R.

Note: Arbor length will be 9" long and will have 3/4" high shoulders with1/4" undercut.

The bottom shaft is fixed and the upper shaft will be mounted in a precision "eccentric bearing" and bushings housing. The total offset eccentric of the upper shaft is .375" and placed exactly at the inner and outboard mountings. The theoretical centerline is to be 4.250.

The outboard bearing/shaft housing will be precision machined and center-keyed onto the mill top plate.

Note: The final price of this machine is determined according to specific tailoring - arbor widths, speeds, horse powers, scrap winders, and number of recoiling arbors - that caters to the customer's specifications.

High Production 1 1/2" x 6" Mini Slitting Line

This precision slitting line is used to cut narrow width, multiple strips of light gauge metal sheet, burr free, and in coil form. It is equipped with the following: a double recoiler with air operated clutch, variable speed, solid state D.C. motor, recoiler mandrels with separate disks, uncoiler with tension control, all electronics, and an operator station.

The tooling is available from stock or it can be specially ordered to size. The spacers come with rubber vulcanized or the rubber can be purchased separately.

The best reason to consider this high production line is its unique combination of the precision alignment and the adjustment of the arbors with the high precision roller bearings they rotate on. This design concept derived from over thirty years of experience and knowledge of slitting.

In order to validate our confidence in the quality of our design, we will gladly demonstrate the slitter's capabilities on materials of your preference.



In addition to these two standard models, International Rolling Mills will build slitters to your specifications and size range for optimum results and productivity.
