A trimmer apparatus for removing flash from the inner diameter opening and the peripheral surface of a molded diaphragm. A molded diaphragm is placed on a rotatable fixture secured in a turret. Upon activation of an electrical switch the fixture is rotated to a press member station. In this location the turret is held stationary to allow a retractible member to engage a die member under the diaphragm to remove the flash from the inner diameter. In response to an operation signal the retractible member is raised from the die member and the turret is indexed to a cutting member. The cutting member presses the peripheral surface of the diaphragm against the fixture and is guided by the external surface of the diaphragm to simultaneously remove the flash from the outer edge of a diaphragm while the press member is in operation.
