Metal slot cutting tools

Only a few teeth are engaged at any one time in side and face milling operations, which can generate heavy torsional vibrations due to the intermittent machining. This is detrimental to the machining result and to productivity. Cutters that have bore mounting with 2 keyways can be arranged in a staggered pattern for milling more than one slot at the same time.

Displacing the cutters in relation to each other assists in avoiding vibration. This also reduces the need for fly-wheels. Versatile cutters have multiple edge inserts that are available in shapes to fit most types of small grooves. Common applications include the machining of internal circlip and seal ring grooves and of small straight or circular external grooves, particularly on components that cannot be rotated.

End milling is selected for shorter, shallower slots, especially closed grooves and pockets, and for milling key-ways. End mills are the only tools that can mill closed slots that are:. Heavier slotting operations are often performed using long edge milling cutters.

Machining a groove or slot, often called full slotting, involves three machined faces:. This operation requires some specific guidance, in addition to the general recommendations for milling of straight surfaces and grooving. A slot milled in a single step will not have a perfectly square form due to the direction of the cutting forces and the tendency of the tool to bend. The best accuracy and productivity will be achieved if the operation employs an undersized end mill, and is divided into two steps:.

For shallow slots, peck milling can also be an alternative. Circular ramping is used for milling wider slots and pockets. Unit of measurement Metric Inch. Save settings. Milling Milling Shoulder milling. Face milling. Profile milling. Groove or slot milling.

Side and face milling Side and face milling cutters can more efficiently handle long, deep, open slots, and provide the best stability and productivity for this type of milling.

How to apply Choose cutter size, pitch and position so that at least one edge is in the cut at all times Check chip thickness to achieve the optimum feed per tooth In demanding milling, check the requirements for power and torque. Stiff arbors and overhang are very important in applications in which arbors have a free end Fixture and arbor support must be strong to handle up-milling cutting forces Down-milling: First Choice method Use a firm stop in the direction of tangential cutting forces to prevent them from forcing the workpiece down against the table.

The feed direction corresponds with the cutting forces, which means that rigidity and eliminating backlash are also important, since the cutter has a tendency to climb Up-milling: Alternative in applications where problems arise due to insufficient rigidity, or when working on exotic materials Solves problems generated by weak setups and chip jamming in deeper grooves Flywheel: Good complement for weak setups and when available power and torque are low Position the flywheel as close to the tool as possible Strengthening the workpiece mounting is always a good investment Milling open slots using side and face milling cutters.

Calculating feed per tooth A critical factor in peripheral milling using side and face milling cutters is achieving a suitable feed per tooth, f z. Flywheel — on horizontal machines Only a few teeth are engaged at any one time in side and face milling operations, which can generate heavy torsional vibrations due to intermittent machining. Employing a flywheel is often a good solution for reducing these vibrations. Problems caused by insufficient power, torque and stability in the machine are often solved by the correct use of flywheels The need for a flywheel is greater in a small machine with low power, or in a machine with greater wear, than in a larger, more stable and powerful machine Position the flywheel as close to the tool as possible.

Using a flywheel results in smoother machining, which in turn leads to a reduction in noise and vibration, and longer tool life In addition to up-milling, a flywheel can be fitted to the arbor on which the milling cutter is set up In order to further improve stability when side and face milling, use the largest possible flywheel that the application permits Combining a number of round carbon steel discs, each with a center hole and key groove to fit the arbor, remains the best method for constructing a flywheel Gang milling using cutters mounted in a staggered pattern Cutters that have bore mounting with 2 keyways can be arranged in a staggered pattern for milling more than one slot at the same time.

Milling of narrow and shallow slots and grooves Versatile cutters have multiple edge inserts that are available in shapes to fit most types of small grooves.

Internal grooving A smooth entrance should be programmed when using circular milling. The smaller the relationship, the larger the engagement will be. End milling of slots End milling is selected for shorter, shallower slots, especially closed grooves and pockets, and for milling keyways.

End mills are the only tools that can mill closed slots that are: Straight, curved, or angled Wider than tool diameter, designated pockets Heavier slotting operations are often performed using long-edge milling cutters.
