AMC-Schou K-1500U Crankshaft Grinding Machine

The AMC-Schou K-1500U is a heavy-duty crankshaft-grinding machine built to tackle mid- to large-size crankshafts, ideal for engine rebuild shops, diesel rebuilders, and industrial engine shops. With a long between-chuck capacity (up to 64″ / 1625 mm) and a large swing-over-table (690–750 mm / 27–29.5″), this “U”-style grinder gives you flexibility to work on long or large-diameter crankshafts that smaller grinders can’t handle.

 

Built on a rugged cast-iron bed with robust bearings and hydraulic controls, the K-1500U is designed for stability, precision, and longevity — even under heavy shop use. It’s a workhorse for shops that want dependable, repeatable journal grinding for mains or rods without constantly needing to outsource.

Key Features

  • Extended Capacity — Max distance between chucks: 64″ (1625 mm); swing over table up to 29.5″ (750 mm), letting you handle long shafts or larger diameters.
  • Hydraulic Controls for Smooth Operation — Hydraulically operated wheel slide, tailstock, and wheel-face locking pins (for “U” machines) ensure smooth, backlash-free motion and reliable setup.
  • Heavy-Duty Build & Precision Bearings — Over-dimensioned headstock and tailstock bearings (double tapered rollers), antifriction-coated way surfaces, and maintenance-free hardened ball screws & nuts deliver long service life and consistent accuracy.
  • Flexible Grinding Specs — Workpiece spindle speeds stepless from 15–90 rpm; table traverse stepless up to 158 in/min; wheel slide rapid traverse up to 118 in/min — giving control whether rough or finish grinding.
  • Large Workpiece & Wheel Capacity — Accepts crankshafts up to 2,200 lbs between chucks, and supports a 32″ (813 mm) grinding wheel (with ¾″–2″ wheel width), making it suitable for a wide range of crankshaft sizes.
  • Shop-Ready Configuration — Hydraulic power unit with oil cooler, coolant pump, tailstock manometer, and standard steady-rest capability — ready for production work out of the crate.

Built on Real Engine-Rebuilding Experience

Decades before today’s engine shops trusted our equipment, Tony was already deep in the craft — rebuilding motors, machining blocks, and pushing for better precision.

A local newspaper once featured him as a standout young machinist, noting his drive, attention to detail, and obsession with doing things the right way. That same passion would eventually shape our company’s values.

Today, that commitment lives on in every machine we sell, every customer we support, and every shop we help succeed.
