Common problems and solutions

1, tap tapping difficult, easy to break?

(1) bottom intake too little bit selection: based on the matrix material with suitable diameter drill bit.

(2) bit wear caused serious bottom hole drill into a cone: switch to a new drill bit.

(3) the bottom hole deflecting: bottom hole scrap.

(4) the tap and inappropriate substrate material: selected suitable substrate material in the tap.

(5) caused by directly using the molding cone: first use Ⅰ cone tapping.

(6) tap wear: steel wire spiral sets of special internal thread bottom hole plug gauge testing, if the gauge impassability is to switch to a new tap.

(7) tapping, tap and different heart bottom hole: correct operation.

2, wire jump in the process of using a screw buckle?

(1) using a screw locking type steel wire installation wrench with ordinary steel wire: a screw in use and matching the installation of a screw spanner.

(2) in steel wire installed on the handle a screw on axial force is too large, should not impose axial force.

(3) selection of drill bit too roughly within the thread type shallow: bottom hole scrap, switch to the appropriate diameter drill bit.

(4) the tap wear caused severe internal thread tooth type shallow: wire screw tap within the special plug gauge testing, general rules can switch to a new tap.

(5) type steel wire spiral teeth half Angle error is too big: exchange with manufacturers.

(6) steel wire spiral sets of diamond wire type surface seriously ultra poor: exchange with manufacturers.

(7) installed greatly too forcibly thrust when installing the handle: remove reshipment or switch to handle with installation of steel wire spiral sets.

3, steel wire installed a screw plug gauge test check gauge more than how to do?

(1) the plug gage accuracy level do not tally with the steel wire spiral sets of precision grade: order should be according to the grades of plug gage accuracy when used with grades of steel wire spiral sets.

(2) the improper use plug gauge, such as English 55 ° tooth type Angle gauge testing unified thread (UN) series 60 ° tooth type Angle steel wire spiral sets:

In series with the same plug gauge.

(3) the bottom hole drill is chosen too large: switch to the right of the diameter of the drill bit.

4, steel wire installed a screw plug gauge testing gauge impassability or screw screwing in rocky?

(1) plug gauge tong gauge could not but sometimes it will be conducive to the screw nut after positioning.

(2) locking type steel wire after a screw locking ring plug gauge of gauge impassability as normal.

(3) the plug gage accuracy level do not tally with the steel wire spiral sets of precision grade: order should be according to the grades of plug gage accuracy when used with grades of steel wire spiral sets.

Choose bottom intake too little bit (4) : switch to the right of the diameter of the drill bit.

(5) choose improper plug gauge, if use unified thread (UN) series 60 ° tooth type Angle gauge testing imperial 55 ° tooth type Angle steel wire spiral sets:

In series with the same plug gauge.

(6) wire jump appeared in the process of installation of a screw tooth caused by: remove the reshipment.
