CNC Engine Block Blueprinting Conversational Programming
Automatic CNC Engine Block Blueprinting: CNC Probing. 

CNC engine block blueprinting begins by making very accurate measurements of the existing cylinder bore, lifter bore and deck location compared to the blueprint locations so corrections can be made. Our CNC Engine Block blueprinting machine is equipped with the Renshaw probe which automatically locates and measures cylinder bores (diameters, locations and angles), deck heights, and lifter bores with the factory blueprint.

Our Master machinist runs the automatic CNC probe routine comparing the entire block blueprint with the probed locations. The CNC Control displays the actual diameters and positions of the cylinder bores, lifter bores, deck heights and compares it to the factory specs. The operator then chooses to make any modifications necessary in order to maximize the maximum blueprinted specifications.

CNC Engine Block blueprinting starts with the CNC Probing routine. The routine compares the engine blocks blue print locations against the block specific blue print data. The Fourth Axis 360 Degree Rotate fixture utilizes Precision Datum and Rings that locate from the Main and Camshaft centerlines. CNC line boring will correct the main centerline. The block decks and cylinder bores are corrected to the crankshaft and camshaft centerline. The cylinder bores are bored on the blueprint center distances to blueprint specs. This process is achieved through the use of the 4th Axis 360 degree rotating fixture that references the crankshaft and camshaft centerline at a true 45 degrees. The block is probed from the centerline then indicated from the dowel location. This enables the bore spacing to be corrected and blue printing the deck surfaces square to the camshaft and crankshaft centerline at a true 45 degree angle is achieved. The dimensions are imputed to the CNC control holding tolerances to 0001. The Engine Block Blueprinting accuracy is achievable with CNC machinery and specialized Datum plates, and tooling along with the CNC Engine Block Blueprinting probe routine.

The Rottler F69A CNC Machine enables R & L Engines to re-machine the lifter bores and correct their position in an engine block front-to-rear and up-and-down, as well as to restore the correct lifter bore angle as referenced from the cam-crank centerline. Rottler F69A CNC Engine Block Blueprinting machine utilizes the Renshaw Probe with the lifter blueprinting program to positions the precise blueprinted lifter bore location and angles.

Our Rottler F69A CNC Engine Block Line Boring process utilizes the right angle drive line bore cutter head. This virtually eliminates bar sag found on traditional line boring machines. The end results is perfect alignment with round and straight main line bores.

CNC Deck Engine Block Deck Squaring
CNC Engine Block surfacing. 

CNC Engine Block squaring 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.  CNC block surfacing tooling included CBN and PCD tooling produces the exact RA surfaces finishes  for superior gasket performance.
