Lock case milling aggregate

Lock case milling aggregate refers to a horizontal milling aggregate on CNC-machining centers which is sufficiently strong dimensioned to mill out the opening for a lock case.

Variants

  • Fixed installed horizontal milling motor, usually milling from the rear to the front, so as not to unnecessarily restrict the working range. Since most machines have a tool changer at the rear, which must be approached by the main spindle outside the working range, both the space and the traversing range of the Y-axis extend far enough behind the machine to accommodate a horizontal milling aggregate with a lock case milling unit without restricting the working range.
  • In some cases, this milling motor is equipped with a separate C-axis, this makes the lock case milling aggregate more universal and can also be used for other purposes.
  • Double-sided lock case milling aggregate: This is a drive motor which has an output for a milling tool on both sides or drives two spindles via a gearbox. Often, one side is equipped with a lock case milling unit, the other side with a short milling tool for the forend milling. However, this requires the ability to rotate. In the case of a fixed motor, the "short" side is used for milling of bands at the front of the machine. This requires a sufficiently large working range to be able to process the workpiece from the front with the lock case milling aggregate.
  • 2 motors: Instead of a single motor with 2 spindles, two lock case milling aggregates are occasionally found. In this case, the rear spindle is usually used for milling the lock case, while the front spindle is used for milling bands.
  • tiltable aggregate: Some lock case milling aggregates can be tilted (usually at a fixed angle of 7°) in order to drill the holes for drill-in bands ("Anuba bands") with the lock case milling unit.
  • mortising aggregates: Occasionally, a oscillating-chisel mortising aggregate (less commonly a chain mortising aggregate) is used to mill out a right-angled lock case to achieve a perfect fit. As a rule, the mortising aggregate is supplemented by a horizontal milling motor for forend milling.
  • change aggregate: As change aggregates, lock case milling aggregates are usually strongly cranked. This serves to make better use of the available working range, since lock case milling units are relatively long. As a rule, the tool holder of a special lock case changing aggregate is located exactly under the center of the spindle.
