CNC Machine Tool >> Grinder >> Toyoda GL4P-100EII
The Toyoda GL4P-100EII is purpose-built for production OD grinding yet nimble enough for short-run aerospace, medical, and R&D work. Hydrostatic X-axis ways and hydrodynamic spindles eliminate stick-slip and extend spindle life, while Toyoda's stator-controlled linear motor keeps positioning smooth even during aggressive plunge cycles. The 39.4 inch (1000 mm) center distance gives you room for longer shafts, rolls, and transmission components, and a swiveling wheelhead lets operators move between straight and angular operations without breaking setup.
Toyoda's GC50 control delivers conversational prompts, live grind charts, and on-screen gauging routines, so machinists can move from setup to spark in minutes. Dresser management, program storage, and ToyodaSTAT diagnostics reduce downtime and document wheel offsets for ISO or PPAP traceability. The casting is fully enclosed with mist-ready ventilation, magnetic paper-bed filtration, and front-service panels that make routine maintenance fast.
Because the GC50 exposes generous I/O, the GL4P-100EII is simple to tie into gantry loaders, robots, or in-process gauging packages from Marposs or BSI. Optional steady rests, dual-wheel dressers, and part probing help the grinder hold tight tolerances hour after hour in lights-out cells.

Toyoda GL4P-100EII FAQ
The EII revision added Toyoda's stator-controlled linear motor on the X-axis, improved enclosure sealing, faster GC50 control hardware, and enhanced hydrostatic pressure management for better straightness on long strokes.
Yes. The wheelhead swivels +20° / -30°, so you can dress a straight wheel for OD work then swing to grind shoulders, chamfers, or simple angles without changing fixtures.
