Perfect Port Matching!

No other machine matches the accuracy of the the CENTROID porting system. Our superior combustion chamber side to manifold side matching guarantees that your design is being machined right where it is supposed to be.

Digitize and cut on the same machine

Automatic Digitizing copies your original hand ported head, CENTROID's DP4 Digitizer runs on the CNC machine so there is no need for an extra digitizing machine.

Versatile CNC Machine

Multi use machine: Port Cylinder heads and intake manifolds, machine combustion chambers, engrave letters, numbers and symbols, add o-ring grooves and more. V8 heads, V6 and 4 cylinders, Import and motorcycle engines.

Patented Ballscrew-Driven Design

CENTROID's tilting rotary table was designed specifically for CNC Cylinder head porting. Made in the USA of rigid cast iron the TRT 32-100 provides 32 degrees of tilt in each direction (64 degrees total) so the tool can cut even the most radical ports. Where others have tried CENTROID has succeeded with this ingenous robust design which produces fantastic ports even better than machines costing twice as much!

Integrated Automatic 5-axis Digitizing!

Digitize and Cut using the same machine and the same control software. No extra software to learn, no extra CMM machine necessary to digitize a head. The same setup menus used to cut are used to digitize. Real 5-axis Digitizing method is a CENTROID exclusive time saving feature that produces better results than the competition. No comparison to the 3 axis patch method the CENTROID 5-axis intake and exhaust port digitizing is fast and accurate. No other system can beat it!

Designed for Cylinder Head Digitizing

CENTROID's DP-4 probe and software is specifically designed for digitizing cylinder head intake, exhaust ports and combustion chambers. This patented probe has special features just for cylinder head copying. Simple for users to specify copy resolution for the most accurate and best results.

Automatic Head Setup

Not only is the probe used to copy your custom shapes, the same probe automatically sets the Head zero locations on the fixture. Quick, Accurate, Automatic part setup saves you time and makes setup simple.

Ultra accurate, stainless steel construction, advanced patented circuitry, interchangeable styli, Made in the USA

Automatic CNC Block Blueprinting: CNC Probing

Blueprinting any block begins by making very accurate measurements of the existing features so corrections can be made. The old way of laborious manual measurement has been eliminated. The CENTROID A532-PB CNC Block machine is equipped with a high tech digitizing probe which automatically locates and measure cylinder bores (diameters, locations and angles), deck heights, and lifter bores with our exclusive easy to use block specific conversational software. To measure an entire block, simply choose the features to blueprint and the probe automatically measures the block and displays the actual diameters and positions of the cylinder bores (and other features) and compares it to the factory specs. The operator then chooses to make any modifications necessary.

The CENTROID DP-4 Probe is a state of the art, made-in-USA highly precise probe which can detect in all axis and directions. Since the probe is made by CENTROID the entire probing system is integrated and streamlined into the CNC machine, making block digitizing and probing a quick and simple process. Much more accurate, faster and repeatable than manually blueprinting a block!

CNC Engine Block Cylinder Boring

Automatic Boring cycles are pre programmed and are menu driven with a simple fill-in-the-blank format. 360 degree CNC rotary axis will position the block at the exact blueprint angle automatically. Machine both cylinder banks with the same setup. Block database saves your work for future jobs. Bore on probed centers, blueprint, or any other specified location. Specialized boring tooling included. Quick, simple programming gets the job done accurately the first time. Operators program the block work to be done right at the machine.

CNC Engine Block Surfacing

With a quick push button tool change the machine will surface the block to the exact deck height specified. The probe automatically detects the block existing surface height at multiple locations so the operator can choose the proper surface depth to machine to for a perfectly flat and square deck to the cylinder bore. Specialized CNC block surfacing tooling is included which produces incredibly smooth surfaces for superior gasket performance.

CNC Spot Facing

Spot Face Lifter bores automatically. You have the ability to create and save your programs with CENTROID user friendly CNC Block software. No need to go out of house or learn G codes, our easy to learn Block Software is made specifically for engine builders saving you time.

CNC Lifter Bore Machining

Machine lifter bores to the exact diameter, location and angle needed with one simple setup. True up the stock size and location or bore complete new diameter, location or angle. Easily control feed and speed within the CENTROID conversational software, the computer remembers your data for the next job as well, no need to reprogram. Easy manual override of programmed feeds and speeds via the operator control panel makes fine tuning adjustments easy to do on the fly.

4-Bolt Main Bearing Cap Conversion

The best way to accurately convert a block to 4 bolt mains. Automatic CNC drill and tap routines are pre programmed, the operator simply answers a few questions and the machine does the rest. CNC Angle Drilling and tapping for perfect 4 bolt main conversions.

Cylinder Bore Chamfering

Chamfer cylinder bores automatically. Operators specifies amount of chamfer. Machine chamfers perfectly concentric with bore.

O-Ring Grooving*

Add o-ring grooves the the deck of any block. Any width and any depth, operator specifies oring specs and the machine does the rest.

* O-ring tooling is optional.

CNC Block Lightening

Automatically remove excess material. The probe copies the shape of the block and creates a tool path that perfectly matches the contour of every detail.

Choose the amount of material to remove, press cycle start, and the tool will machine the block surface to your specs.

CNC Engine Block Engraving

Quickly and easily engrave letters, numbers, symbols and logos. Phone numbers, serial numbers, web addresses and company logos are now simple to automatically add onto every block you blueprint.
