Perfect PFG spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of Perfect PFG spindles and motor spindles — PFG series CNC and NC surface grinders, found in grinding and precision engineering workshops.
Perfect PFG, surface grinders for precision grinding
TLDR: The PFG series from the Perfect brand covers table-type surface grinders, with grinding cycles and wheel dressing controlled by CNC on some models.
PFG machines (for example PFG-50150 AH, PFG 60100 AHR, PFG 70150 AHRD) are surface grinders from the Perfect brand. Used machine listings show them with table sizes of 700 × 1,500 mm and with varying controls: NC-controlled grinding cycle and wheel dressing on a 1999 model, 2-axis digital readout on a 2014 model.
The wheel spindle, the heart of precision
TLDR: On a surface grinder, the wheel spindle determines surface finish and flatness. On a PFG 70150 AHRD found, it delivers 7.5 kW at 1,450 rpm for a 355 × 40 × 127 mm wheel.
On a surface grinder, the wheel spindle directly governs flatness, surface finish and wheel life. A listing for a PFG 70150 AHRD (2014) gives a 7.5 kW (10 hp) spindle at 1,450 rpm, with a 355 × 40 × 127 mm wheel. A listing for a PFG-50150 AH (1999) gives a 406 × 50.8 × 127 mm wheel. Runout or bearing play on a Perfect PFG spindle shows immediately on the part, so every Perfect PFG motor spindle is inspected in our workshop before overhaul. The specifications of your spindle are to be confirmed on quotation.
