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.

Red RHINO 5 AXIS CNC Cylinder Digitizing and Porting Machine.

Complete turn-key CNC Cylinder head porting package. 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.

Our employees desire to meet and exceed the quality and accuracy demanded of your precision cutting tool specs during the entire production life cycle. We in turn go out of our way to earn your repeat business on future projects.  We encourage you to get a quick quote from us on stock purchases, or custom tool making jobs.

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 is ready to meet your exact application needs. Our engineers are capable of working from existing designs or starting from scratch to develop truly specialized tools for industrial and commercial applications. Whatever the case, we'll work closely with you to determine the correct tools for your application. Give us a call at 1-989-777-3890, or use our quote request form.
