How big is a bottom hole in ZG1 8?

A thread is a continuous convex part of a specific cross-section made in the shape of a helix made on the surface of a cylinder or conical matrix. Threads are divided into cylindrical threads and tapered threads according to their parent shape; According to its position in the matrix, it is divided into external thread and internal thread, and according to its cross-sectional shape, it is divided into triangular thread, rectangular thread, trapezoidal thread, zigzag thread and other special shape threads.

In machining, the thread is cut with a tool or grinding wheel on a cylindrical shaft, at this time, the workpiece rotates, the tool moves a certain distance along the workpiece axis, and the traces cut by the tool on the workpiece are threads. The thread formed on the outer surface is called the external thread. The thread formed on the surface of the inner hole is called the internal thread.

The basis of the thread is the helix on the surface of the round shaft. Usually if the cross-section of the thread is triangular, it is called a triangular thread; The cross-section is trapezoidal, called trapezoidal thread; The cross-section is zigzag, which is called a zigzag thread; The cross-section is square, which is called a square thread; The cross-section is arc-shaped, called arc-shaped thread, and so on.

The tap of ZG1 8 should be the bottom hole; It belongs to the inch conical pipe thread tap; Its tooth shape angle should be 55 degrees.

Z1 8 taps.

The same goes for the bottom hole.

It belongs to the American thread 60 degrees!

Correctly, ZG1 8 represents the tapered pipe thread, with the base surface requirements, and the DT1 of the inner diameter of the pipe end thread: for, is the approximate value of the thread bottom hole, you can check the ZG thread table.

The ZG thread represents the link used for the pipe, and the general nominal diameter refers to the passage of the pipe.

It's a screw:

The diameter of the internal thread of ZG1 8 is, minus 2 times the tooth height, i.e., equal.

13mm

Threads are divided into connection threads and transmission threads.

Connecting snails to know the bleeding:

1. The triangular thread, also known as the ordinary thread, is the most commonly used connection thread, with good self-locking performance and high strength.

2. Cylindrical land rental thread, commonly used in water, gas, lubrication and cable pipeline systems.

3. Tapered pipe thread.

It is often used in high-pressure, high-temperature, or high-sealing piping systems.

Transmission thread: 1. Rectangular thread, which has the highest transmission efficiency, but the root strength is weak and easy to wear, and it has gradually been trapezoidal thread.

replaced. 2. Trapezoidal thread, good manufacturability, high root strength, good neutralization, is the most commonly used transmission thread.

3. The sawtooth thread has the characteristics of both rectangular thread and trapezoidal thread, but it can only be transmitted in one direction.

Common thread coarse thread m is the most commonly used type of connection thread, and the pitch of the fine thread when the diameter is the same.

The pitch is smaller than that of the coarse thread, and the coarse thread does not carry the ridge pitch.

Fine thread, pipe thread Non-threaded seal g Commonly used threads in pipe connections, the pitch and tooth profile are smaller, and their size codes are in units, which are approximately equal to the pore diameter of the pipe. The large diameter of the thread should be found from the relevant standards, the code R represents the conical external thread, RC represents the conical internal thread, and RP represents the cylindrical internal thread.

How big is the Z1 8 threaded bottom hole.

ZZ1 8 threaded hole bottom hole mm. Because the annotation method of this thread is Z1 8-28, the inch thread represented by it, there are 28 threads within one inch, then its pitch is that its thread diameter is rotten, and its bottom hole is rotten and the diameter of its bottom hole is d=, so its bottom hole diameter is mm. Generally, the processing method of this thread is tapping, its cutting speed is v=12-18 meters per minute, and the feed is millimeters per revolution.

Summary. Hello dear, Z1 8 threaded bottom hole has millimeters, generally take millimeters. This thread is 28 threads per inch, with an effective length of 9 mm, a length of millimeters from the end of the pipe to the base, a large diameter of the thread of millimeters, and a taper of 1:16

How big is the Z1 8 threaded bottom hole.

Hello dear, Z1 8 threaded bottom hole has millimeters, generally take millimeters. This thread is 28 threads per inch, with an effective length of 9 mm, a length of millimeters from the end of the pipe to the base, a large diameter of the thread of millimeters, and a taper of 1:16

ZZ1 8 threaded hole bottom hole mm. Because the annotation method of this thread is Z1 8-28, which represents an inch of the inch thread, there are 28 threads in one inch, then its pitch is, its thread diameter is d=, and its bottom hole diameter is d=, so its bottom hole diameter is millimeters.

The diameter of the internal thread of ZG1 8 is, minus 2 times the tooth height, i.e., equal. The calculation is like this, and it is still no problem to drill the bottom hole in practice.
