Speciality engine boring and CNC machining tools from SFS

Porting a car engine's cylinder head refers to fine-tuning the shapes of the ports that direct airflow to and from the cylinders. To improve its process for porting, a manufacturer of high-performance heads for racing engines will use a multitasking machine that is capable of milling and turning under CNC control.

Cylinder porting is one of the most difficult machining jobs. But it is especially important to the engine shops that build the 700-plus horsepower engines for NASCAR and other professional racing teams. Horsepower, torque and acceleration are the keys to winning a race; refining the art of porting can give a team the edge they need to win. It all begins with choosing the right machining tools to blue-print the engine block cylinders, heads and manifold to exacting standards.

When it comes to superior cylinder porting, the majority of high performance engine shops in the world have several things in common: Surfcam CAD/CAM software by Surfware, Inc., Westlake Village, CA.... and the precision cutting,boring and milling tools furnished by SFS Carbide Tool Company.

The powerful yet easy to use the CENTROID M400 CNC control will digitize your hand shaped Intake, Exhaust and combustion chambers in 5 axes. Easy export to Mastercam X via the ethernet LAN or USB port to create the toolpaths. Inverse time tool paths are generated for the smoothest fastest cut possible. Very little hand work is necessary after the machine has ported the head.

CNC Tools for Engine Builders matches just the right SFS Carbide Tipped tool for the job. A new casting is placed on the machine, the operator sets the Zero point, loads the cutting tool and the control machines the exact shape that was copied from the original hand shaped port. Rough and finish passes are automatically created. CNC Intake, Exhaust and Combustion Chambers are all created in this way.

In addition to porting heads this machine is also a fully featured 5 axis cnc machine that can be used for a multitude of other engine related machining tasks such as: Cylinder head O-ring grooves, piston work, intake manifold work, and anything requiring drilling, tapping, pocketing, contouring, grooving, boring, facing, Engraving and more! ....

The process of porting is more of an art than a science. An initial prototype is created by hand, tested for optimum airflow and power, then refined by hand machining until the desired performance is achieved. For a prototype cylinder head one exhaust port, one intake port and one chamber are developed. Once the design is complete, the part is digitized and computerized surfaces are generated. To create all of the ports required for a cylinder head, the port surfaces are duplicated and positioned in the correct locations. Then the CNC toolpath is generated to cut the part. CAM/CNC machining the ports in this manner is faster and produces a better quality product. Ports can be cut in less than one tenth the time it takes to cut them by hand and the ports are consistently the same. Once a design is complete any number of heads or manifolds can be produced that are exactly alike, if your machining tools hold to consistant tolerances.

Factoid: CNC controllers are devices that control machines and processes. They range in capability from simple point-to-point linear control to highly complex algorithms that involve multiple axes of control. CNC controllers can be used to control various types of machine shop equipment.  These include horizontal mills, vertical mills, lathes and turning centers, grinders, electro discharge machines (EDM), welding machines, and inspection machines.  The number of axes controlled by CNC controllers can range anywhere from one to five, with some CNC controllers configured to control greater than six axes.

SFS Carbide Tool Company Inc

Dart Industries uses SFS carbide tools in their high performance engine building projects. Dart Machinery began in humble surroundings. Richard Maskin founded Dart in 1981 in a two-car garage in Oak Park, Mich. In the years since Maskin started his business with desk and a telephone, Dart has become the leader in aftermarket cylinder heads, intake manifolds and engine blocks. Maskin is well known to drag racing fans as a mechanical mastermind whose engines have won NHRA Pro Stock championships and dozens of national events. Like many successful entrepreneurs, Maskin turned his passion for drag racing into a thriving enterprise.

Maskin’s Pro Stock roots were evident in the Race Series heads for big-block Chevrolet V8s that soon followed. In recent years, Dart’s spread-port Big Chief heads have set the standard in classes ranging from Pro Street to Pro Mod. This tradition of innovation continued with the introduction of affordable Iron Eagle and PRO 1 cylinder heads for small-block and big-block Chevy V8s.

Dart Performance Heads and engine blocks are drag racing legends.

The company has expanded its product line to include aluminum and cast-iron engine blocks that are designed to meet the specialized needs of racers and performance enthusiasts. Dart components are developed in-house, manufactured on Dart’s own CNC machining centers, and tested on Dart’s computer-controlled engine dyno. Maskin keeps current with the continuous advances in racing technology through Dart’s in-house engine program. Dart also supports the sport as an NHRA and IHRA Major Sponsor.

“Our engine program and our daily interaction with leading engine builders and winning racers keeps Dart on the leading edge of technology,” Maskin explains. “We apply everything we learn to produce more powerful and more reliable parts for Dart customers.”Dart Machinery’s Technology Center in Troy, Mich., houses the company’s administrative offices, the R&D headquarters, and inspection, machining and warehouse operations. The immense CNC machining centers that produce Dart heads and blocks from raw castings are located in a separate manufacturing facility in nearby Melvindale.
