Description

Gleason-Pfauter P400/600G Form Gear Grinder — Recertified & Re-Controlled by Machine Tool Builders

The Gleason-Pfauter PE725G is effectively a 'stretched' model P400/600G. This machine is a heavy, rigid, and extraordinarily capable form gear grinder—well suited for high-accuracy production of spur and helical gears, pinions, shafts, splines, and similar profiles using vitrified or CBN grinding wheels.* This machine is being fully recertified and re-controlled by Machine Tool Builders, incorporating MTB’s latest grinding technology platform, conversational form-grinding software, optional on-board inspection, integrated wheel dressing, and our Electronic Setup Assistant (MESA). Once complete, the machine will be delivered ready for immediate precision production.

* This machine is currently set up without a dressing system. Based on customer demand, a dressing system will be applied at time of build.

Grinding Spindles & Wheel Options:
The standard wheel spindle accepts 250 mm OD wheels with a 76.2 mm arbor. Optional spindles—127 mm arbor (300 mm wheel) and 50.8 mm arbor (200 mm wheel)—may be available pending confirmation.
Wheel changes typically require less than five minutes. Spindle changes take longer, so MTB generally recommends selecting a single common spindle size for all grinding wheels to streamline workflow and lower tooling overhead.

Control Platforms & Options:
• Pfauter PE725G base platforms.
• Siemens or Fanuc controls (inspection Siemens-only).
• Marposs high-accuracy scanning probe or equivalent.
• Configurable tooling, workholding, probing, and wheel packages.
