Digitize and Machine in 5 axes! Copy hand shaped Intake and Exhaust ports and reproduce exact same port shape on new castings. Our state of the art 5 axis system is a quantum leap ahead of the others, with 5 axis digitizing and inverse time machining produces faster better results. Sold as a turn key system which includes extensive CNC cylinder head porting training.
                     
Cylinder Head Porting tilting CNC rotary table.   The TRT-25-100 Tilt Table provides precise cylinder head positioning to within .001" repeatability. The unique ballscrew design outperforms other dual rotary designs (trunnion) on the market. Fully programmable 5 axis Tilt table allows the cutter or the digitizing probe to reach into curved ports. Full 360 degrees of rotation and 50 degrees of tilt allow you to get into all those hard to reach spaces. The Tilt table can hold a wide range of cylinder heads.
                     
CENTROID 5 Axis CNC control   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 toolpaths are generated for the smoothest fastest cut possible. Very little hand work is necessary after the machine has ported the head.

Graphics of the digitized path and the tool path shows you your work as you go.

The reliable CENTROID CNC control is made in the USA and has the best reputation ease of use and advanced features which make your job easier.
                     

Cylinder Head port Digitizing

   The CENTROID Digitizing feature is used to copy the hand shaped intake runner. This is an automatic process, no operator attendance is needed. The CENTROID CNC control automatically copies the intake runner shape in 5 axes! The machine both rotates and tilts to perfectly reach all the detail of the port. You can both copy and cut the new shape on the same machine. CENTROID makes the digitizing process simple to operate. CENTROID Digitizing is highly accurate.

This super accurate probe has been specifically designed for cylinder head digitizing and outperforms other probes on the market.
                     
CNC porting an Intake Runner.   Once the data has been turned into a tool path, a new raw 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 head. Rough and finish passes are created automatically. CNC Intake, Exhaust and Combustion Chambers are all created in this way.

CENTROID's 5 axis tool motion is the smoothest cutting on the market, very little hand work is required after the head has been CNC ported. Rough and Finish passes are created automatically for the best possible surface finish.
                     

CNC ported vs. Stock.

   Results! The Atrump E320 produces a very nice surface finish. After the machine is finished cutting the new Intake runner only minor sanding is needed for a smooth shape.

The port on the left was just CNC ported. Click on the photo for a high resolution image so you can see the surface finish as it is directly from the machine. No sanding was performed on this port!
                     
The Atrump E320 CNC Porting Machine can also be used for common cylinder head machining tasks such as: O-ring grooves and Engraving letters and logos.

* Automatic Tool Changer notice: Auto tool changers are available with the E320 however they are not recommended on a CNC Porting Machine and are not necessary since CNC porting requires often only one Digitizing tool and one Cutting tool. Save time and money, our customers have found that the added complication and expense of an ATC on a CNC porting machine is just not necessary.
