Comec SPN800 Belt Sander

The SPN800 is a belt-sanding / resurfacing machine designed to quickly and efficiently grind or finish flat metal surfaces — ideal for engine parts like intake/exhaust manifolds, valve covers, sumps, cylinder-head faces (after rough machining), pans, and any plate-style components.

 

It’s built for simplicity and speed: operation is foot-pedal controlled, belt changes are quick with Comec’s quick-release system, and no complicated clamping or setup is needed — making it a great “shop-friendly” machine for finishing or prepping parts before final assembly.

 

Because of its straightforward design, SPN800 is often used as a cost-effective alternative when full resurfacing machines (mills or CBN/PCD surfacers) are overkill or when initial surface prep is all that’s needed.

Key Features

  • Flat-Surface Finishing for Engine Parts — Excellent for parts like intake manifolds, exhaust manifolds, cylinder-head castings, covers, pans, and any flat metal surface requiring smoothing or prepping.
  • Simple Foot-Pedal Operation — The grinding belt is activated using a foot-switch, enabling hands-free control and easier handling of parts.
  • Quick-Release Belt System — Belt replacement is fast and straightforward, minimizing downtime and making maintenance easier.
  • Decent Working Envelope for Small/Medium Parts — Max working area of 800 × 300 mm, sufficient for many engine covers, heads, manifolds, and plate-type parts.
  • Balanced Power & Speed — 3-kW (4 HP) motor driving a belt speed of ≈ 3.2 m/s, giving consistent, controllable material removal without requiring high-power industrial gear.
  • Compact & Shop-Friendly Footprint + Manageable Weight — Full machine dimensions of 1560 × 550 × 420 mm, and weight around 160 kg — manageable even in smaller shops or crowded workspaces.

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.
