Arrangement for preventing chip from flying about in crankshaft miller

A crankshaft miller comprising:

• a rotary cutter drum carrying a plurality of tips;
• work supports supporting both ends of a work to be processed;
• work resting means including a rest main body and rest arms pivotably mounted on said rest main body for gripping a portion of said work in the vicinity of a portion of said work being machined;
• a plurality of chip deflecting covers positioned in vicinity of said rest arms, each of said covers including:
• first cover members with a covering plane perpendicular to axis of said work support, said first cover members are rigidly fixed on said rest main body, said first cover members defining a first opening, and a peripheral edge of said first opening being located away from the outer peripheral surface of corresponding said work support for defining an annular clearance therebetween, and
• second cover members arranged within said annular clearance between the peripheral edge of said first opening and the outer periphery of said work support for surrounding said corresponding work support with a covering plane perpendicular to the axis of said work support, and said second cover member being detachably secured on said first cover member.

A crankshaft miller for processing a workpiece, comprising:

• a rotary cutter drum carrying a plurality of tips;
• work supports supporting both ends of said workpiece to be processed;
• cover means for preventing the release of chips produced by said miller positioned in the vicinity of said rotary cutter drum, said means including:
• first cover members operative to provide said work supports with a covering plane extending perpendicular to an axis of an associated work support, said first cover members each defining a first opening of a size for allowing an adjacent work support to pass therethrough, said first opening having a peripheral edge spaced from an outer peripheral surface of an adjacent work support to define an annular clearance therebetween;
• and
• second cover members disposed within said annular clearance defined between the peripheral edge of said first opening and the outer peripheral surface of said work support for surrounding said corresponding work support, said cover members defining a covering plane perpendicular to the axis of said work support, and said second cover members being detachably secured to said first cover member.
