Abstract:
The present invention provides an apparatus and a method for manufacturing a wheel hub to reduce lateral run-out. Specifically, the present invention provides an apparatus and a method for machining the inner and outer surfaces of the wheel hub after the wheel bolts and bearing have been attached to the wheel hub. A grind wheel is used to finish an inner flange portion and outer flange portion of the wheel hub.
Abstract:
A piston pin hole boring system and method of forming pin holes therewith includes fixing a piston to a fixture supported by a slide member. Then, rotating a cutting member about a first axis and moving the slide member with the fixture thereon toward the cutting member along the first axis and bringing the piston into cutting contact with the cutting member. Further, moving the fixture along second and third axes, each extending transversely to the first axis and machining the desired pin hole contours in the piston with the cutting member.
Abstract:
A door machine is provided for the production of a raised-panel door product of the type having a central panel framed in a sash of left and right stiles and upper and lower rails. In this type of raised panel door, the stiles and rails are joined by four butt joints to form the sash which features four inner edges that join the four edges of the central panel in edge joints. Preferably, the rails extend between and space apart the stiles and as such, these rails have opposite "butt" edges. The door machine includes a stand and a table on the stand formed with openings. The table and stand support a power and drive assembly which includes at least driven three spindles. Each spindle has a head for mounting a knife, and this head protrudes through an opening in the table as slightly above a plane of the table. The knives include a panel knife and an associated fence for shaping all four edges of the central panel, a stile knife and associated fence for shaping each inner edge of both stiles and both rails, and a coping knife and associated fence for shaping the butt edges. Altogether, the spindle heads and fences are spatially distributed around the table to avoid interference with one another for the shaping work to be performed by each spindle.
