Gleason-Pfauter PE725G Form Gear Grinder (Built 1998) — Available As-Is, Running Siemens 840C Controls
The Gleason-Pfauter PE725G is effectively a "stretched" model P400/600G. This machine is heavy, rigid, and extraordinarily capable — well suited for high-accuracy production of spur and helical gears, pinions, shafts, splines, and similar profiles using vitrified or CBN grinding wheels. This unit is offered as-is, in its current running condition, on its original Siemens 840C control system.*
This machine is currently set up without an on-board dressing system, as it was configured for Cubic Boron Nitride grinding operations with fixed workpiece designs.
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.
Current Configuration:
Pfauter PE725G base platform.
Siemens 840C control system (as originally equipped).
Sold and delivered in current, running as-is condition — no recertification, re-control, or upgrade included.
