May I ask which domestic CNC bending machine has better quality after sales?

The ** of CNC bending machines is about tens of thousands of yuan per unit, the cheap ones are one or two thousand yuan, and the expensive ones are one or two hundred thousand yuan. The first CNC bending machine is affected by many aspects, such as brand, category, specification, market, etc. The key is to learn how to choose.

Workpiece, the first important thing to consider is the part you want to produce, the point is to buy a machine that can do the machining task with a short table and a small tonnage. Careful consideration is given to the material grade as well as the large processing thickness and length. If most of the work is low-carbon steel with a thickness of 16 gauge and a maximum length of 10 feet, then the free bending force does not have to be greater than 50 tons.

However, if you are engaged in a large number of bottomed die molding, you may want to consider a 150-tonnage machine tool. Well, let's say the thicker material is 1 4 inches, 10 feet of free bending takes 165 tons, and there is a bottom....

Yangli and Jin Fangyuan's are good. Don't buy the golden ball, the golden ball is home**, the model sent is not the one you want at all, the full CNC is replaced by a semi-CNC one for you, be careful.

Find one that is close to your company, which is relatively safe.

It is advisable to investigate, and seeing is believing.

Ma'anshan Sany Heavy Industry Machinery Manufacturing **** machine tools are good, and after-sales service is also very good.

Guangzhou Puneke CNC, quality and service are good, can be compared.

Top 10 brands of CNC bending machines:

1. Wuxi Golden Ball.

Wuxi Jinqiu Machinery Co., Ltd. was established in 2001 with a registered capital.

15 million yuan, mainly engaged in the manufacture and processing of ordinary machinery and spare parts, Wuxi Jinqiu CNC bending machine is well-known among many users.

2. Shanghai Xinli.

Shanghai Xinli Machinery Factory is a state-owned enterprise, founded in 1958, formerly known as Shanghai No. 6 Machine Tool Factory, affiliated to Shanghai Aerospace Bureau.

Responsible for the development and production of hydraulic sheet metal bending machines and shearing machines, etc., as a state-owned enterprise production products have a certain guarantee.

3. Guangdong Guangzhou Shipyard.

Founded in 1954, Guangzhou Guangzhou Shipyard International Co., Ltd. is one of the top 500 domestic manufacturing enterprises, mainly producing marine supporting equipment, cutting tools and mechanical parts processing, and is also one of the top ten domestic bending machine brands.

4. Tianshui, Gansu.

Tianshui Forging Machine Tool (Group) ****, mainly involved in the research and development, production and sales of forging machine tool equipment, local well-known enterprises, product quality is guaranteed.

5. Guangzhou Lifeng.

Lifeng Machinery **** is a well-known bending machine brand in China, which belongs to Lifeng Group and is also a relatively powerful machinery manufacturer.

6. Huangshi, Hubei.

The same is a brand named after the place name of the bending machine, in the country has a very high reputation, widely loved by users, to distinguish different manufacturers, each manufacturer for the maintenance of products are different.

7. Shanghai punching and shearing factory.

Shanghai Punching & Shearing Machine Tool Factory, founded in 1931, has brand trademarks such as "SPS", "AS" and "Shangchong", and belongs to Shanghai Electric Group.

Head office, the enterprise has a number of offices in many companies across the country to provide after-sales service.

8. Changjie brand.

Yuhuan Jiezhong Tools ****, located in Taizhou, Zhejiang.

The main production of hydraulic bending machines, cutting machines and bending machines and other tools, is also one of the top ten domestic bending machine brands.

9, Huade. Anhui Huade Machine Tool Manufacturing, founded in 2006, registered capital of 10 million yuan, mainly produces bending machines, shearing machines, rolling machines, presses and other mechanical tools, while the import and export of various commodities and technologies.

10. Daikin laser.

Jiangsu Daikin Laser Technology Co., Ltd. was established in 2010 with a registered capital of 11.2 million yuan, mainly involved in the assembly, research and development and sales of electronic products. Among them, the press brake is also a relatively well-known product.

As of 2020, the first level of CNC bending machines ranges from tens of thousands of yuan to more than 100,000 yuan.

Under the same load, the deflection of the table and slide of the 10-foot machine is 4 times that of the 5-foot machine. This means that a shorter machine requires less gasket adjustment to produce a good part.

Reduced gasket adjustment also shortens preparation time. The grade of the material is also a key factor. Compared to mild steel, stainless steel typically requires about 50% more load, while most grades of soft aluminum have about 50% less.

A tonnage table of the machine is readily available from the press brake manufacturer, which shows an estimate of the tonnage required per foot of length at different thicknesses and materials. At the same time, when free bending is adopted, the bending radius is multiple of the opening distance of the die.

If the bending radius is less than the thickness of the material, a punch with a corner radius less than the thickness of the material must be used, and the impression bending method must be resorted to. In this way, 10 times the pressure of free bending is required.

According to the parameters provided, you can use an 80-ton press brake, and you can go to Bowang, Ma'anshan City.
