Abstract
PURPOSE:To permit the one chucking work and improve efficiency and permit the square hole working having a high accuracy by installing a broach onto a main spindle by an automatic tool replacing device and carrying out the square hole working succeeding to a forework. CONSTITUTION:When the lead hole working in a forework is completed, a main spindle 6 is stopped, and a saddle 2 is shifted in the Z-axis direction, and a main spindle head 5 is shifted in the Y-axis direction, and positioning at a replacement position E is performed. A twin arm 14 holds a broach for the next tool and a lead hole working tool after use at the same time by a tool replacement instruction under NC control, and the both tools are pulled out at the same time by the advance of the arm 14. Then, the arm 14 inserts the next tool onto the main spindle 6 and inserts the tool after use into a ready station pot 12. The tool after use in the pot 12 is returned to a magazine pot 8, and a broach holder 20 is engaged with a positioning block 31, and positioning in the revolution direction is performed, and said holder 20 is clamped. Then, the lead hole in the forework and the broach 18 are set concentric by the shift of the main spindle head 5 and the saddle 2, and a cutting edge part 18b is pushed, in and a square hole is formed.
