A cutting tool for removing material from an engine block structure includes an engine block structure support sized to receive the engine block structure, a platform having a longitudinal dimension and a width dimension, and a cutting assembly supported on the platform and movable in a longitudinal direction along an adjustable rail, and movable in a direction approximately orthogonal to the longitudinal direction, the cutting assembly including a rotary cutter. The cutting tool also includes an alignment mechanism including an engagement structure configured to secure the cutting assembly to one of a plurality of predetermined positions on the adjustable rail, and an adjustment mechanism for moving the adjustable rail and cutting assembly in the longitudinal direction to position the rotary cutter to a desired position.

Cutting machine and method

A hydraulic system includes a housing having a housing bore defined by a bore inner surface, wherein the bore inner surface has an internal thread formed thereon and an insert having a flange formed adjacent a first end, a sealing feature formed adjacent a second end opposite the first end, and a cylindrical outer surface extending between the first end and the second end, the cylindrical outer surface having an external buttress thread configured to mesh with the internal thread of the housing bore. The sealing feature and the flange are configured to interface with the housing to provide a fluid seal.

An alignment assembly for a rotating thermal sprayer may include an elongated alignment base that connects at one end to a sprayer positioning assembly connection mechanism, and an indicator device disposed at the opposite end of the alignment base and rotating about a sprayer rotational axis defined by the sprayer positioning assembly. The indicator device may have a visual indicator operatively connected to a stylus so that a display of the visual indicator changes when the stylus moves relative to a stylus neutral position. The sprayer positioning assembly may position the stylus in contact with a concave surface that will be coated, such as an engine bore, and the indicator device rotated about the sprayer rotational axis to determine whether display of the visual indicator changes to indicate if the sprayer rotational axis is aligned with a longitudinal axis of the concave surface.
