AMC-Schou K-1200CNC Crankshaft Grinder

The AMC-Schou K-1200CNC is a precision crankshaft-grinding machine engineered for small to mid-size crankshafts, ideal for engine rebuild shops, performance shops, and diesel rebuilders. Built on a heavy cast-iron bed, with hardened guideways and CNC control (X, Z and C axes), the K-1200CNC delivers repeatable accuracy, smooth operation, and efficient workflow — whether you’re grinding main journals, rod journals, or balancing throws. Standard equipment includes universal chucks, steady rest, crank-centering gauges, coolant system, and dressing tools — meaning the machine is ready to grind shafts right out of the crate.

 

This model is especially well suited for shops that value precision, reliability, and controlled setup time — with a compact footprint compared to larger “U-style” grinders, yet still offering enough capacity for many common crankshafts.

Key Features

  • Standard-Ready Package — Comes with universal chucks, steady rest, crank-centering V-gauge with dial indicator, set-up indicator, grinding wheel & balancing arbor, coolant system, splash guards, dressing tools, and operating manual. No extra kit needed to start basic crankshaft regrinding.
  • Solid Construction & Precision Bed — One-piece cast iron bed with protected guideways, plus antifriction-coated sliding surfaces and rack & pinion head/tailstock movement for smooth, backlash-free crankshaft rotation.
  • CNC-Controlled Axes for Accurate Grinding — Uses a CNC 3-axis controller (X, Z, C) with servomotor-driven headstock and wheel-slide, allowing precise, repeatable journal grinding and consistent results across multiple crankshafts.
  • Flexible Journal & Shaft Capacity — Maximum distance between centres: 48″ (1220 mm) / swing-over-table: 18″ (460 mm) — accommodating many standard crankshafts.
  • Responsive Movement & Control — Wheel-slide rapid traverse speed up to 3000 mm/min (118 in/min), and stepless workpiece rotation (20–100 rpm) for efficiency and fine control.
  • Complete Grinding Setup Out-of-the-Box — Includes coolant system, wheel balancing arbor, wheel dressing tools, and guards — reducing need for extra purchases.

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.
