thumb V-Blocks are precision metalworking jigs typically used to hold round metal rods or pipes for performing drilling or milling operations. They consist of a rectangular steel or cast iron block with a 90-degree channel rotated 45-degrees from the sides, forming a V-shaped channel in the top. A small groove is cut in the bottom of the "V". They often come with screw clamps to hold the work. There are also versions with internal magnets for magnetic workholding. V-blocks are usually sold in pairs. ==External links== * (How to make a V-block ) the inventor of the V Block was Harold Arlington Sneckner http://patentimages.storage.googleapis.com/pdfs/US2449255.pdf 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「V-block」の詳細全文を読む スポンサード リンク
