What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

What’s the difference between screw, bolt and nut?

(1) bolt:

A type of fastener consisting of a head and a screw (cylindrical body with external thread) to be fitted with a nut for fastening two parts with through holes.This type of connection is called the bolt connection. If the nut is unscrewed from the bolt, it can also make the two parts separate, so the bolt connection is a detachable connection.

(2) screws:

A kind of fastener composed of head and screw can be divided into three types according to their uses — machine screws, setting screws and screws for special purposes.Machine screws are mainly used for fastening connection between a part with an internal threaded hole and a part with a through hole, without nut matching (this connection form is called screw connection, also a detachable connection;It can also be used with a nut for fastening connection between two parts with through holes.Set screws are mainly used to fix the relative position between two parts.Special purpose screws are ring screws for lifting parts.

The best material is 316 corrosion resistant stainless steel, followed by 304.Carbon steel is the next most common material.

The standard of hexagon nut and utility have what

As a standard part, nuts and rivets with pull mandrel have their own standards.Xiaobian on the hexagon nut standard is summarized for the difference and connection and their use.

For hexagon nuts, the commonly used standards are:

GB41 Ⅰ Hexagon nuts — Class C

GB6170 Ⅰ type hexagon nut — A, B grade

GB6171Ⅰ Hexagon nuts — fine tooth — grade A and B

GB6172 Hexagon thin nuts — Class A and B — Chamfered

GB6173 Hexagon thin nuts — fine tooth — grade A and B

GB6174 Hexagon thin nuts — Class B — No chamfering

GB6175Ⅱ type hexagon nut — A, B grade

GB6176Ⅱ type hexagon nuts — fine tooth — grade A and B

GB6177 Hexagon flange nuts — Class A

GB55 hexagon thick nut

GB56 hexagon ultra thick nut

GB1229 Hexagon nuts (high strength for steel structures)

1, ordinary hexagon nuts: widely used, characterized by large fastening force, the disadvantage is that there should be enough operating space in the installation, the installation can use a live wrench, open wrench or glasses wrench, the wrench above all need a lot of operating space.

2, cylinder head hex nut, is the most widely used in all the screws, because its binding force is larger, can use Allen key operation, the installation is very convenient, when used in almost all kinds of structure, more beautiful and tidy appearance, defect is slightly lower than outside hexagonal fastening force, also repeated use can't remove the socket head broken easily.

3, disk head hexagon nut: rarely used in machinery, mechanical properties of the same, mostly used in furniture, the main role is to increase the contact surface with wooden materials and increase the appearance of the ornamental.

4, headless hexagon nut: some structures must be used, such as the need for a large jacking force of the top wire structure, or the need to hide the place of the cylindrical head.

5, countersunk hex socket nut: mostly used in power machinery, the main role of the same hex socket.

6. Nylon lock nut: it is inlaid with nylon apron in hexagonal face to prevent loosening of thread. It is used in strong power machinery.

7, flange nut: mainly play a role in increasing the contact surface with the workpiece, mostly used in pipes, fasteners and some stamping and casting parts.
