摘要:
The subject matter of the present invention is an installation for machining crankshafts, camshafts or like workpieces. Each of the workpiece is mounted in non-rotary condition in a workpiece holder. A plurality of such workpiece holders is guided on a straight path with their workpieces in co-axial relationship to each other and to said path. A plurality of tool units is distributed in spaced relationship along the path. Each unit includes an annular rotary tool having internal cutting edges. This tool surrounds an internal clearance space which is larger than the cross-section of the workpiece holders. Therefore, each tool affords passage of said workpiece holders through the clearance space. Each of the tool units further comprises means for moving the annular rotary tool into a position in which its internal clearance space is in registry with the path of the workholders. Conveyor means are provided for intermittently transporting said workpiece holders with the workpieces on a guideway along the path through the clearance spaces of the tool units and for temporarily stopping each workpiece holder in a position in which its workpiece is surrounded by said annular rotary tool and in a position to be machined by the cutting edges thereof. The conveyor means may comprise drag members which are distributed along the path and are adapted to engage the workpiece holders. These drag members are reciprocated parallel to said path in synchronism with each other and thereby feed each of the workpiece holders step by step along the path consecutively through the annular rotary tools.
摘要:
A milling method for machining a metallic member to provide a finished appearance is provided. A metallic member is positioned on a worktable. The metallic member includes a top portion and a peripheral sidewall. The peripheral sidewall includes an end edge. After rotation, the milling cutter is rotated and resists the peripheral sidewall of the metallic member. The milling cutter is moved along a predetermined path, and the milling cutter machines the metallic member to achieve a required shape and finish. The worktable rotates the metallic member to enable the end edge of the peripheral sidewall to face the milling cutter, and the milling cutter chamfers the end edge along a predetermined path, while simultaneously controlling a feed of the milling cutter relative to the metallic member.
