Boring tool is a kind of hole processing tool, generally round handles, and a larger workpiece using a square knife rod is generally seen in the car. The most commonly used occasions are hole processing, hole expansion, and profiling. However, it is not only possible to process the inner hole, but also the outer circle of the end surface can be processed, but it is not customarily used in this way.
Installation steps for boring cutter
1, bolt the bridge with a bolt 1 on the handle
2, install the fine boring knife base on the knife bridge
3, the weight block is installed on the sliding body
4, tool adjustment:
1) Loosen locking screws;
2) According to the rough adjustment of the scale, the size of the knife tip is less than 0.5 mm of the desired size,[ Note: The rough size is guaranteed by compound adjustment of fine boring knife base and dial.] ;
3) Tighten the locking screws, unscrew the adjusting screws(on the precision boring knife holder), and tighten the locking screw bars at the top to prevent the knife from being used;
5, use the same method to adjust the weight block, adjust the balance;
6, lock the lock screw, test boring, measuring the size of the machining hole and the required size comparison, calculate the partial small value;
7, loosen the lock screw, twist the disk(the dial of the dial represents a change in diameter and depth of 0.01 mm per rotation), so that the amount of movement to the calculated small value;
Lock screws and process the workpiece to size.
Pay attention to the adjustment of the boring knife head, do not excessively force(do not rotate the dial beyond the scope);
The place sealed with red paint can not be removed, otherwise it will damage the fine-tuning device;
Regular maintenance, lubricating oil.
