Aluminum Milling Cutters

February 01, 2015

Millstar offers its new Aluminum Milling Cutters line. This versatile aluminum cutting insert line features modular screw-on heads, shell milling and end mill cutters. All of the featured products come in side clearance options.

"Our aluminum cutting insert line is diverse, boasting a wide variety of holding options, multiple insert sizes, a 90 degree option and back draft capability," said Walter Stuermer, sales manager for Millstar. "The inserts are also extremely effective in material removal during roughing operations, leaving an outstanding finish in the process."

To demonstrate the line's product performance and material removal efficiency during roughing operations, Millstar partnered with CNC Machining Manufacturer Hurco Companies Inc. The shell tooling cutting parameters--18,000 RPM, 1134 IPM, .05 depth-of-cut and 1.75 stepover--helps to illustrate its optimal performance.

"This line demonstrates how Millstar is maximizing return-on-investment," Stuermer said. "Multiple operations and unrestricted cutting conditions in a single set-up allows versatility, efficiency and ultimately more throughput at a lower cost per part for the end user."

Related Glossary Terms

  • clearance


    Space provided behind a tool’s land or relief to prevent rubbing and subsequent premature deterioration of the tool. See land; relief.

  • computer numerical control ( CNC)

    computer numerical control ( CNC)

    Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.

  • gang cutting ( milling)

    gang cutting ( milling)

    Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.

  • inches per minute ( ipm)

    inches per minute ( ipm)

    Value that refers to how far the workpiece or cutter advances linearly in 1 minute, defined as: ipm = ipt 5 number of effective teeth 5 rpm. Also known as the table feed or machine feed.

  • milling


    Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.

  • milling machine ( mill)

    milling machine ( mill)

    Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.
