How to grind taps to be more durable, and how to use taps?

This part is replaced with an extrusion tap, and the effect will be better. Check the concentricity of the lathe spindle and tailstock taper, and it is recommended to use **taps; The tap does not need to be sharpened, and the cutting fluid must be suitable when the new tap is used, and the lubrication function must be satisfied. The method of tap grinding is the same as that of the cutter, the rear angle is less than the front angle, and the angle is less than the obtuse angle; Generally, after smoothing the end face, only the first few teeth can be repaired.

Otherwise, the teeth will be rotten. Good taps are used for machine taps made in Shanghai Herbin. 10 plastic boxes, not 2.

The excretion groove of the tap is widened, so that the iron is cut out, and the teeth will not be large, and it is very easy to use, and it is very fast. The knife edge of the tap is worn out, and it should be resharpened in time. As with the edge of the hob, the end face should be sharpened.

In this way, the tap always stays sharp.

Taps are a kind of tools for processing internal threads, which can be divided into spiral taps and straight-edged taps according to the shape, hand taps and machine taps according to the use environment, metric, American, and imperial taps according to specifications, and imported taps and domestic taps according to the place of origin. Taps are the most important tool for manufacturing operators to process threads.

How to grind will not have a new durability, the general tap is not grinding, use up to replace the new, large tap English ** is more expensive, only to consider grinding, but grinding is only to reach the original life of 7-9 into, a large tap according to the processing material and the actual situation, generally can grind 3-5 times.

How to use: 1. When tapping, insert the head cone first to make the tap.

The centerline is consistent with the drill hole centerline.

2. Rotate evenly with both hands and apply a little pressure to make the tap enter the knife, and there is no need to add pressure after feeding.

3. Reverse about 45° every time you turn the tap to cut off the chips to avoid blockage.

4. If the tap is difficult to rotate, do not increase the rotation force, otherwise the tap will break.

Taps are divided into the following according to different drivesHand and machine taps; According to the processing method, it is divided into: cutting tap and extrusion tap; According to the thread to be processed, it is divided into:

Metric coarse taps, metric fine taps, pipe thread taps, etc.; According to its shape, it is divided into: straight groove tap, spiral groove tap and screw tip tap; According to the tapping direction of the tap when used, it is divided into: smooth tap and inverted tap.

Place the wire dimension horizontally and gently turn it from the cutting edge to a little bit (1 3 or 1 4 silk grooves), so that the cutting edge is a little higher than the back. (I just grinded it out)4. To grind a little arc, the cutting edge can be a little higher than the back, which is more durable.

5。When grinding, the mouth is slightly smaller. Same as the head attack of New Silk Dimension.

6。The length is a little more than the new silk bevel. It's easier that way.

7。Be careful, practice more, try more, and grind more. When you don't grind out a good silk dimension, don't be discouraged, you have to persevere, or it won't take a few months.

You're just going to be a grinder. 8。I wish you a good hand as soon as possible.

When you are grinding, the table must be aligned with zero, and it must not form an angle with the rotation plane of the grinding wheel. You also need to control the grinding wheel not to make the rake angle of the grinding tap negative, otherwise the inner diameter of the tap will become larger, and even the tooth will rot. \x09

Taps are divided into two kinds: manual and mechanical, if it is a mechanical silk grinding, please replace it immediately, if it is a manual silk dull, grinding short can be reused, you can grind the front end lightly, and keep the back end. If it is a machine and grinding, it is often a gain or loss, either a broken tap or a tapping is not up to standard, remember to remember.
