Miller for machining bicycle pedal housing - has cutter mounted on double ended spindle fixed in turn on each side and knurled nut acting through spring adjusts pressure

摘要

A method of accurately machining the two sides of a bicycle pedal housing (8) consists of a double ended shaft (1) mounted through the pedal housing along the crank axis and held in position by a sliding boss (2). The cutter (3) is fixed on the housing (4) which rotates on the bearing (5) mounted on the shaft (1). A knurled button (7) acting through the spring (10) is used to exert the required pressure. When machining is completed on one side, the cutter is removed and replaced on the other end of the shaft to machine the second side.
