Comec AC200 Cylinder Boring Machine

The Comec AC200 is a versatile, heavy-duty cylinder boring machine designed for reconditioning engine blocks from cars, trucks, and light commercial vehicles. It handles a broad bore range and comes equipped with precision controls, making it well-suited to shops that rebuild blocks in-house. The AC200 combines a robust mechanical structure with updated technical solutions, delivering reliable performance and finishing quality for manual or performance-oriented engine work.

 

As a shop-ready tool, the AC200’s adjustable speeds, variable feed, and precise centering system give flexibility for different cylinder sizes and materials — from small-bore automotive blocks to larger truck applications within its supported range.

Key Features

  • Wide Boring Diameter Range — Accepts cylinders from 30 mm to 170 mm (≈ 1.2″ – 6.7″), covering most car and light-to-medium truck engine blocks.
  • Generous Head & Table Travel — Head vertical travel up to 670 mm (26.4″) and table-to-head clearance variable between 370 mm – 1,020 mm (14.6″ – 40.2″), allowing accommodation of blocks of varying sizes.
  • Adjustable Spindle Speed & Feed Rates — Spindle speed adjustable from 75 to 850 rpm, and boring-bar feed adjustable up to 175 mm/min; this flexibility helps you match feed and speed to material and finishing requirements.
  • Variable Table Feed & Long Table Travel — Table longitudinal travel up to 1,200 mm (47.2″), and transverse travel of 200 mm (7.9″) — useful for block machining setups. Table feed is also adjustable (on applicable versions) for more control.
  • Precision Centering & Depth Control Tools Included — Standard supply includes fast cylinder-centering device (with scanning level on the boring bar), dial-indicator centering gauge, and boring-depth control gauge — all aimed at speed, accuracy, and repeatability.
  • Compact Footprint & Shop-Friendly Design — Overall machine size: 1860 × 1150 × 2170 mm (≈ 73″ × 45″ × 86″) — relatively compact for a cylinder boring machine, making it feasible even for moderate-sized shops.

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.
