Roughing end mill Roughing end mills quickly remove large amounts of material. This kind of end mill utilizes a wavy tooth form cut on the periphery. These wavy teeth form many successive cutting edges producing many small chips, resulting in a relatively rough surface finish. During cutting, multiple teeth are in contact with the workpiece reducing chatter and vibration. Rapid stock removal with heavy milling cuts is sometimes called hogging. Roughing end mills are also sometimes known as ripping cutters.

Broaching with Production Keyway Broaches

Broaching with Production Style Keyway Broaches requires no Shims or Bushings. The back and shoulders of the Broach are ground to fit the diameter of the bore, supporting and guiding itself while cutting the keyway in one pass. All individual stock Broaches have recommended Minimum and Maximum Length of Cut guidelines which should be followed. Workpieces may be stacked to establish the Minimum Length of Cut, or to improve the efficiency of the operation as long as Maximum Length of Cut is not exceeded. Proper nesting and clamping of stacked parts is vital when this approach is taken. The workpiece must be solidly fixed or nested perfectly square with the baseplate and ram face. Make sure all square and parallel surfaces on the face of the ram and baseplate remain true. It is essential to maintain a rigid set-up at all times and caution should be taken when stacking parts to maintain the integrity of the set-up. Never attempt to exceed the Broach's specified Maximum Length of Cut. Do not use a dull Broach, this may result in poor finish or damage to part and increases the danger of breakage. At the beginning of a cut, be sure the Broach is centered under the ram. Proper alignment is important. After the Broach starts to cut, back off pressure on the ram allowing the Broach to center itself, providing for better alignment. If the Broach moves out of alignment after starting cut, back off the pressure on the ram and align the broach itself. Repeat this procedure during successive cuts. This will assure a perfectly straight broached hole..

Select desired Broach and insert pilot into bore of part.
    Lubricate.
    Apply pressure to the Broach - back off pressure on the ram allowing the Broach to center itself, providing for better alignment. If the Broach moves out of alignment after starting cut, back off the pressure on the ram and align the broach itself - reapply pressure to push Broach through the work.
    Clean Broach using a stiff brush to remove chips from cutting section.
    Repeat steps 2 thru 4 for subsequent parts.
