Slide cores (with finish machining ) are the optimal production method for the intersecting holes.

Slide Cores

The upper accelerator casting has two intersecting holes for fitting the actuator and the drive cylinder.

  • The primary cylinder has a 1" ID; the secondary hole has a 3/8" ID. Machined tolerances are +/- 0.003".

The best way to form these features is to use TWO intersecting slide cores to form the holes in the casting, followed by finish machining for precise tolerances.

Cores have a distinct cost advantage over the full production run, compared to a two step machining operation for both holes.
