Key Features

  • Wide Bore Capacity — Handles cylinder bores from 0.98″ (25 mm) up to 10.22″ (260 mm / 60 mm) — covering most engine blocks and large industrial cylinders.
  • Long Stroke for Deep Bores — Max honing stroke of 20″ (508 mm), allowing deep cylinder honing for long bores or large engine blocks.
  • Adjustable Spindle & Feed Speeds — Infinitely variable spindle rotation (32–315 rpm) and reciprocating stroke speeds (5–20 m/min) give flexibility to match different materials and honing requirements.
  • Hydraulic Stone Pressure Control (Type A) — Allows precise control of stone pressure (manual/automatic mode), ensuring consistent cross-hatch pattern and bore geometry.
  • Robust Work Table & Travel Capacity — Large table surface and traverse accommodate various block sizes; table-to-spindle clearance lets you hone long blocks without compromise.
  • Precision Finish & Cross-Hatch Quality — The design ensures a clean, even cross-hatch finish on every cylinder — crucial for piston ring seating, lubrication retention, and long engine life.
  • Durable Industrial Construction — Built with heavy-duty castings and hydraulic systems for shop-floor reliability, even under heavy use.

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.
