Patented Ballscrew Design

CENTROID's ballscrew drive articulating head was designed specifically for CNC Cylinder head porting. Made in the USA of rigid cast iron, the articulating head provides 60 degrees of tilt in each direction (120 degrees total) so the tool can cut even the most radical ports. The design of the A560 minimize tool motion for fast smooth cutting action. The unique ballscrew drive of the articulating head produces the smoothest 5 axis action on the market. The design also overcomes back lash and maintenance problems found with our competitors machines. Where others have tried CENTROID has succeeded with this ingenious robust design which produces fantastic ports.

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 B4250 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

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.

* 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.

“Using the DP-7 probe and Centroid digitizing cycles you can digitize specific features on a block that can be used to create a block lightening program.”

Threadmilling freeze plug holes. (and other threads)

CENTROID threadmilling canned cycle provides easy fill in the blank programming. Threadmill the threads on blocks and heads. Never break a tap again!

When should a thread mill be selected over taps?

In general, for production threading up to 3/8", taps are more efficient. However, if producing a wide variety of parts, threads, and materials on the same machine, threads mill are far more versatile. They will produce right or left hand, internal or external threads, single or multiple lead from #2-56 with the same mill. Materials range from soft, non-ferrous alloys to heat-treated steels, or tough alloys such inconel and titanium, where tap breakage often occurs. Pipe threads are easily produced without leaving the normal “stop lines” and creating the troublesome stringy chips normally produced by taps. In addition, thread mills can produce full threads to within one pitch of the bottom of a blind hole.
