Estimated price range
Our best estimate for a cnc gear cutting machine in this class — not a quote from Pfauter. Configuration moves it a long way.
Overview
The Pfauter P 400 is a gear hobbing machine for external gears up to 400 mm (15.7 in) in diameter, in modules from 1 to 10, on workpieces up to 400 mm long. It hobs spur, helical and worm gears and sprockets. The listed figures are the basis for what follows and should be checked against the machine's own data plate and manual.
Capacity is square in outline: 400 mm (15.7 in) of gear diameter and 400 mm of workpiece length. Length matters for shaft-type parts, where the teeth sit on a long blank that has to fit within the work area. Gear type is restricted to external teeth; internal gears are not on the list.
The hob turns at a maximum of 400 RPM and the table at a maximum of 120 RPM, and the largest hob is 150 mm in diameter. Hob speed and hob diameter together set the cutting speed available, and the table limit caps how fast a gear with few teeth can be rotated in step with the hob. Cutting is listed as both wet and dry: wet is standard, and dry needs appropriate tooling.
Two controls are named, Fanuc 31i or Siemens 840D, so the one fitted has to be established machine by machine. The electrical supply is 400/460 VAC 3-phase at 50/60 Hz, and the machine weighs 10,000 kg (22,046 lb). Hob spindle power and positioning accuracy are not listed.

Frequently Asked Questions
01
External spur, helical, worm and sprocket teeth are listed. The module range is 1-10 and the maximum gear diameter is 400 mm (15.7 in). No internal gear capability is listed.
02
Maximum hob speed is 400 RPM and maximum table speed is 120 RPM. The largest hob the machine takes is 150 mm in diameter. The table limit matters on gears with few teeth, because the work has to turn faster relative to the hob.
03
The control row reads Fanuc 31i or Siemens 840D. It names two alternatives without saying which is standard, so identify the control on the specific machine and make sure your programmers and maintenance staff are set up for it.
04
The electrical row gives 400/460 VAC 3-phase at 50/60 Hz, and the machine weight is 10,000 kg (22,046 lb). Connected power and floor space are not listed, so get both from the machine's documentation before planning the install.
