Comec ACF200 CNC Cylinder Boring Resurfacing Machine

  • Model: ACF200 CNC
  • New Machine; Call for Pricing

The ACF200.CNC is a all-in-one cylinder boring and resurfacing machine for automotive and truck engine blocks. Combining both boring and block-deck resurfacing in a single machine under CNC control, it brings high precision, repeatability, and automation to engine-block reconditioning — ideal for shops wanting to re-bore cylinders and surface deck faces without needing multiple machines.

 

Because of its robust build, wide machining range, and CNC automation, the ACF200.CNC reduces setup time and improves throughput — a good match for shops doing frequent rebuilds, reman work, or high-volume engine block overhauls.

Key Features

  • Dual-Function: Boring + Resurfacing — The ACF200.CNC integrates both major block reconditioning functions (cylinder boring and block-deck resurfacing) in one machine.
  • Wide Bore Capacity — Supports cylinder bore diameters from 30 mm to 170 mm, covering most car and light-/medium-truck engines.
  • Generous Table & Travel Capacity — Table surface 1340 × 370 mm; table longitudinal travel up to 1200 mm; transverse travel 200 mm — accommodating many block sizes and layouts.
  • Strong Vertical Head Travel — Head vertical travel up to 700 mm; head-to-table distance adjustable between 370 and 1020 mm — this flexibility helps handle blocks of varying heights.
  • CNC Automation & Precision — Controlled by CNC (Linux-based ARM system), with precision ball-screw drives on 3 axes, linear rails, brushless motors — ensuring accurate, repeatable boring and milling cycles.
  • Programmable & Automatic Cycles — Automatic and programmable modes for boring and milling operations, reducing operator workload and risk of setup error.
  • Compact Footprint for Shop Use — Despite its capabilities, the machine remains fairly compact for a dual-function block machine, making it practical 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.
