The Comec LBM950 is a CNC horizontal line-boring machine designed to recondition bearing and housing seats in both cylinder heads (camshaft housings) and engine blocks (crankshaft / main-bearing seats) for cars and light trucks.
What makes the LBM950 stand out is its chrome-bar drive system: a linear ball-bearing feed combined with a belt-driven rotation system, delivering smooth, precise, and stable boring. The combination of feed + rotation reduces chatter and improves accuracy — critical when re-boring cam journals or main bearings to factory specs.
The machine’s intuitive operation — via touchscreen control panel + electronic handwheel — simplifies setup and makes it practical even for smaller shops that do cylinder-head or block work in-house. Universal clamping fixtures and moveable supporting arms allow a wide range of head and block sizes to be handled.

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.
