The RMC V40 and V50 CNC Engine Machining Centers are built for shops that demand speed, accuracy, and versatility. Backed by over six decades of RMC engineering expertise, these machines are purpose-designed for the engine rebuilding industry. They combine rugged construction with advanced CNC controls, specialized fixturing, and powerful tooling systems to deliver unmatched performance.
Both models provide true CNC performance with simultaneous 3-axis machining, and optional 4th and 5th axis configurations for handling complex geometry with ease. RMC’s High Production Fixturing System minimizes downtime and boosts throughput—mounting, probing, boring, decking, and dismounting a complete V6 block in just eight minutes, or a V8 in ten. Built for durability, each unit features servo drives, ball screws, linear bearing ways with metal guards, and a fully enclosed design that ensures long-lasting rigidity and smooth operation.

Designed specifically for engine builders, the V40 and V50 excel in every step of the rebuilding process. They handle boring and line boring from 2.6” to 8.0” (with right-angle head options), precision deck milling with 10” or 14” CBN heads, accurate lifter bore machining, and cylinder head or main cap work using included fixtures. Additional features like 360° rotary positioning enable advanced block modifications, while digital probing and blueprinting functions provide on-screen verification of bore diameters, locations, and deck heights.
At the core of these machining centers is the 9000 Series CNC Control—a modern Windows®-based interface featuring a 15” color touchscreen, intuitive navigation, conversational programming, full G-code support, and lightning-fast graphics performance. With its simple yet powerful design, even operators new to CNC machining can achieve professional results quickly and efficiently.
The RMC V40 and V50 can easily expand as your shop’s needs evolve. Optional upgrades include a full head porting conversion system (V40HP/V50HP) that transforms the machine into a precision cylinder head porting station, optional 4th and 5th axis fixtures for advanced machining, and a variety of flexible tooling packages for specialized applications.
With X-axis travels of 40” (V40) and 50” (V50), 20” Y- and Z-axis travels, a 10,000 rpm spindle, and ±0.0002” accuracy, these machines deliver the power, precision, and performance engine builders depend on. Each model supports up to 2,000 lbs of table load and features a 20-pocket tool changer within a compact footprint.
The V40 and V50 deliver unmatched speed, accuracy, flexibility, reliability, and scalability. High-production fixturing dramatically reduces cycle times, while precision machining ensures every surface meets exact specifications. Designed to handle blocks, heads, caps, and lifter bores in one setup, these machines are engineered for long-term reliability and growth.
The RMC V40 and V50 CNC Engine Machining Centers provide everything a modern engine shop needs—speed, precision, and versatility. Whether you’re producing high volumes daily or building performance engines for maximum horsepower, these machines give you the
competitive edge to succeed.
