Radial drilling machine is in use process, of tap breaking off often is to be in those who suffer the case with very great power to issue swiftly happening, cause the cutting blade of the half tap in screw, closely wedge is inside the metal, make the cutting blade of tap and metal are broken away from very hard commonly, to make tap can become loose in screw, can use vibratory drilling method. A pointed chisel is used when vibration, touch inside the chamfer holding bit of tap, press the purpose of the mark of positive and negative of whorl to be beaten gently again and again with hand hammer, become loose to tap all along. The following kinds of quick and restful processing techniques, hope can better land solves this a Gordian knot. 1.

Break off when tap the branch is inside aperture when, usable belt just twists 2 nut on the awl of fracture of wire of tenon, with steel wire (root number and tap chamfer are counted not different) in the empty chamfer that inserts awl of fracture of wire and nut, pull by the purpose that exits mark with bar of bore with a reamer next move square tenon, draw out awl of fracture of wire. If still cannot be drawn out, usable acetylene blaze or blowtorch make tap anneal, be gotten next with broach, right now broach diameter should compare bottom outlet diameter small, bore also should aim at a center, prevent to get whorl bad, infiltrate a flat look or spanner of quadrate drift reoccupy come back after Kong Zuan is good a tap. 2.

When showing workpiece general situation to have 2 ～ 3mm only with tap when the machine that break off, with thick the 2 ～ 3mm, flat steel that grows 150 ～ 200mm, in its length 1/2 place drills one hole (the external diameter) that the diameter of aperture is tap, cover flat steel on awl of fracture of wire again, flat steel and axial end panel stay have 0.

The clearance of 5 ～ 1mm. Solder awl of fracture of wire and flat steel smoothly in with electric welding all the way, solder Shi Yingxian rises from the central solder of tap, solder with flat steel gradually in all the way. When after the tap nature that break off is cooling, discharge engine oil of the infuse in bits chamfer toward what break tap again, order about gently pull use flat steel, shake awl of fracture of wire, can very aimlessly ground draws out tap from inside the axis. Also can use internal diameter summary the eve of the lunar New Year solders at the hex nut of tap diameter. 3.

Show the work when the tap that break off when general situation is longer, can use forceps to twist its. In production industry, often touching tap is carried in the axis, because of these axes kind branch of spare parts the eve of the lunar New Year by process move qualitative arrange, have tall tenacity, high strength, brought a lot of difficulty to tap, often produce meeting hair to get angry to break off with tap phenomenon. A lot of moment cause workpiece because of handling misgivings to discard as useless. CNC Milling
