Problems solved by technology

Despite the potential weight savings, the disadvantage of increasing the market share of cast wheels is the slower manufacturing process when compared to wheels stamped from sheet metal
While the casting process is relatively slow relative to forming sheet metal, the bottleneck in the manufacturing process has always been machine tool operations, especially when forming the holes to accommodate the nuts and valve stems

Embodiment Construction

[0021] A spindle assembly for machining a cast workpiece such as a wheel is generally denoted by Figure 6 40. Fixing device 42 is used to fix a workpiece, such as, for example, a wheel 46 for machining in assembly 40 . Those skilled in the art to which the invention pertains will understand that the description of the wheels in this application is exemplary only and that other cast components may also be machined in the subject assembly 40 . The fixture 42 defines a fixture axis 44 about which the wheel 46 pivots.

[0022] The first spindle 48 and the second spindle 50 extend in opposite directions towards the fastening device 42 . Thus, the first spindle 48 and the second spindle 50 extend in opposite directions on opposite sides of the fixture 42 . as in Figure 6 As best shown in , assembly 40 is defined by a 3-axis Cartesian coordinate system having x, y and z axes. The first spindle 48 provides rotational motion to a first cutting tool 52 about a first spindle axis ...

Abstract

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.

Description

[0001] Prior Art Patent Application [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 040,596, filed August 22, 2014, and U.S. Non-Provisional Patent Application No. 14 / 525,300, filed October 28, 2014. technical field [0003] The present invention generally relates to apparatus and methods for machining workpieces. More particularly, the present invention relates to a spindle machine tool for machining features in a workpiece. Background technique [0004] It is well known that machining features in cast workpieces is a bottleneck in mass production facilities. One such example of a bottleneck in the serial production of cast workpieces is machining such as figure 1 The cast wheel 46 shown in. Cast wheels 46 typically include cut bolt holes 60 and cut valve stem holes 75 , the cutting of which creates a manufacturing bottleneck. [0005] Cast wheels for use on road vehicles are becoming more and more desirable, especially when light...
