A resurfacing machine that includes a spindle carrying a resurfacing tool and an electric motor operatively connected to the spindle and configured to rotate the spindle about an axis. The machine includes a control system, such as a processor and a computer readable medium carrying spindle control instructions thereon. The control system is configured to control the operation of the motor in order to rotate the spindle through a repeating acceleration and deceleration cycle during a resurfacing operation.

A spindle assembly for machining a cast workpiece includes a fixture that provides rotational movement to the workpiece around a fixture axis. A first spindle provides rotational movement to a cutting tool around a first spindle axis and a second spindle provides rotational movement to a second cutting tool around a second spindle axis. The first spindle axis and the second spindle axis are transverse to the fixture axis. The fixture is disposed between the first spindle and the second spindle. The pivotal movement of the fixture provides access to opposite sides of the workpiece to the first spindle and the second spindle enabling the cutting tools to simultaneously cut opposing sides of the workpiece. The first cutting tool and the second cutting tool are replaceable by a third cutting tool and a fourth cutting tool to cut an alternative or different aperture into the workpiece.

A printer cartridge pin exposure and removal apparatus for the removal of embedded pins within a printer cartridge. The printer cartridge is positioned within a cartridge mount and securely held in a fixed position through a clamping mechanism. A first pin extracting mechanism and a second pin extracting mechanism are positioned about opposite ends of the printer cartridge. A first drill and a second drill are supported by and aligned with the printer cartridge through a first drill aligner and a second drill aligner respectively. The first drill aligner moves the first drill towards the printer cartridge, while the first drill drives a first drill bit in order to penetrate the printer cartridge. Similarly, the second drill aligner moves the second drill towards the printer cartridge, while the second drill drives a second drill bit in order to penetrate the opposite side of the printer cartridge.

A cutting tool for boring that is attached to a machining apparatus and used for cutting a hole on a large-diameter side of a stepped hole of a workpiece is provided. The cutting tool for boring is a set of two tools, and each cutting tool for boring in the set of two includes a shaft part, a cutting blade laterally protruding from the respective shaft parts, and an abutment surface formed at the tip of each shaft part and used to cause the tips of the respective shaft parts to butt against each other. Each cutting tool for boring performs cutting while the two cutting tools for boring rotate integrally around the center line of the shaft parts in a coupled state in which the tips of the cutting tools for boring are butted together.
