OUR MANUFACTURING PROCESS

Ross Pistons Pistons Design

STEP 1: THE DESIGN

Each piston first goes through a design phase. Our CAD engineers work with customer orders to modify stock piston designs to meet a specific customer need, or we start with a fresh slate on any engines we aren’t already familiar with.

STEP 2: DRILLING

Our extensive line of forging blanks, start as the ground work for each set of pistons.  In our 1st operation shown here, we’ve drilled pin holes, oil return holes, forced pin oilers, lock removal indents, oil dispersion and pin lock grooves.

STEP 3: TURN DOWN

Pistons are rough turned to within .010 of its finished diameter. The accumulator groove will be cut here if required. The ring lands have been turned down to their correct diameter and the ring grooves have been rough cut to within .002 of the finished width.

STEP 4: MILLING

Next the pistons are moved to one of the milling centers where the side relief, dome or reverse dome, and valve reliefs are cut. Canted valve layouts are moved to a 5 axis machining center.

STEP 5: CONTOURING

Next the bottom of the pistons are contoured to remove weight. Another weight savings option is 3D profiling, where the bottom of the piston is mirror cut with the top of the piston’s shape, giving the same thickness throughout the inside of the piston!

STEP 6: HAND DETAILING

Each Piston is then hand detailed to remove any burrs or minor imperfections.

STEP 7: FINAL MACHINING

During the final machining process the ring grooves are double plunged to prevent groove wave.  This ensures a square groove and excellent finish. The skirt profile and cam are then cut.

STEP 8: PIN FITMENT

The final manufacturing operation is fitting the pins to the pistons on one of the Sunnen automated hones.  There are actually a few more steps to our manufacturing process, but we can’t give away all our secrets.

STEP 9: IDENTIFICATION

The pistons are then engraved with the job card number (identification number) and cleaned. This serves as the piston’s serial number for future ordering or technical support.
