Piston Grinding Question Practical Machinist

May 16, 2016· Another mechanical method is to use a spindle mounted at an angle on a slide and feed the tool down over the OD of the piston while the piston is held in a fixture. This also produces a piston that has the eliptical reach closer to the top of the piston on one side. By offsetting the pin; "piston-slap" (the piston rocking in the bore) is

US6767273B1 Crankpin grinding method Google Patents

A method is described for grinding a crankpin of a crankshaft using computer controlled wheelfeed and headstock drives ( 44,30,24 ). During a final grinding step leading to finish size the cutting force is maintained on the wheelhead ( 38 ) to keep the wheel ( 34 ) and pin under a moderate constant load and the rotational speed of the headstock drive ( 24 ) is reduced.

Inspecting & Measuring the Pistons, Pins & Connecting Rods

If a press-fit pin must be resized for an oversize piston, so too will the piston pin bore. On rods fitted with free-floating pins, bronze bushings are used to support the pin. There are two methods used for their repair: Fit an oversize pin to the rod and piston; or remove and replace and fit a new pin bushing for the same (stock) size pin.

Piston Manufacturing Process It Still Runs

A human worker then smooths out the sharp edges of the piston created during production. The holes created for the wrist pin are then put through a machine which smooths them, allowing the wrist pin to fit comfortably. Finally, the pistons sprayed by hot, deionized water, removing any lubricant or oil gathered through the manufacturing process.
