Comec RP1000.M Cylinder Head and Block Resurfacing Machine

The RP1000.M is a resurfacing machine built for cylinder heads, engine blocks, and other flat mating surfaces — with an emphasis on precision finishing using a milling (CBN/PCD) plate rather than (or in addition to) a grinding wheel. It’s designed for auto, light-truck, and industrial-engine heads/blocks, delivering a reliably flat, factory-like surface finish.

 

The core structure — base, table, column, and head — is heavy cast iron with substantial ribbing for rigidity, giving a stable, vibration-resistant platform. The table motion is driven by a recirculating-ball screw for precise and smooth feed even at slow speeds. Spindle and table feed are both variable via inverters, letting you adjust for different materials (cast iron, aluminum, diesel heads, etc.) and cutting methods (milling or grinding).

 

Because the “M” variant is optimized for milling (with a CBN/PCD/ALP insert-plate), it’s particularly suited for shops that want high-speed, high-quality resurfacing — especially for aluminum heads, alloy blocks, or cast-iron surfaces requiring a fine finish.

Key Features

  • Rigid Cast-Iron Build for Stability — All major structural components (base, table, column, head) are made from heavily ribbed cast iron, ensuring long-term stiffness, minimal deflection, and stable operations even under heavy cuts.
  • Ball Screw Table Feed + Adjustable Spindle Speed — Recirculating-ball screw drive for table feed gives smooth, precise table motion under varied cutting conditions. Separate inverters control table feed and spindle rotation, letting you fine-tune cutting parameters.
  • CBN/PCD Milling Plate (M-Version) — Equipped with a 355 mm (≈ 14″) milling plate and compatible tool holders/inserts (CBN, PCD, ALP) — suitable for both cast-iron and aluminum heads/blocks, including diesel heads with pre-chambers.
  • Versatile Workpiece Capacity — Table travel of 1070 mm, max workpiece length ~895 mm, max width ~355 mm, and height clearance from ~125 mm up to ~545 mm — handles most automotive and light-truck heads and blocks.
  • Manual / Continuous / Automatic Modes — Flexible operation modes: from manual finishing to continuous or automatic cycles (depending on tooling and configuration) — giving the shop flexibility for different workloads.
  • Standard Accessories for Ready-to-Use Setup — Includes parallel supports and clamps (for head/block mounting), splash guard with polycarbonate shield, slide lubrication, tool-set, and optional fixtures for angled heads or V-blocks.

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.
