TOOL FOR WORKING CRANK BORE IN THE CYLINDER BLOCK

摘要

A cylinder block crank bore machining tool is provided to reduce a boring time and the entire process cycle time, thereby decreasing a conveyance time between processes. A cylinder block crank bore machining tool includes a first shaft(31), boring tools(32,33,34,35), first spindles(30), a second shaft, and second spindles. The boring tools are sequentially installed from the first shaft to form a boring part. The first spindles are installed between the boring tools, and have a first milling tool for machining a milling part. The second spindles are sequentially installed from the second shaft, and have a second milling tool for machining the milling part.
