1： Firstly, you need to clarify whether second-hand machine tools are suitable for you. For example, if a friend asks the editor to help them find a second-hand machine tool to make the following products
Clearly tell this friend that it is not suitable to make second-hand machine tools for this product, and quote his original words: China's science is so advanced, why can't this be done? Silent for N days
Suggestion 1: Second hand machine tools can only process things with general accuracy requirements, requiring fine lines below 0.1, or products with high positional accuracy requirements, or products with special requirements. Please try to use new machine tools. Of course, you can buy some new and used machine tools and use them together, which can be a good solution.
2： There are so many brands in the market, what kind of brand model is better to buy?
Try to buy second-hand machine tools from popular brands in the market, such as Shamir, Shadik, Mitsubishi, Xibu, Qinghong, Leitong, etc. Because it's easier for you to find a master, buy parts, and find maintenance personnel...
Suggestion 2: Try to buy popular brands in the market and avoid obscure brands, otherwise you will be very worried later.
3： What year of machine tool would be better to buy
1. The more recent the machine tool, the more expensive it will be, and of course, the safer and more reliable it will be.
2. If you want to be cheap and have good products, you need to watch the entire article because it will be interspersed with many rare dry goods in the market. 4. Dry Goods Point - What is the most important thing to pay attention to when buying second-hand machine tools?
Misconception A:
Many people like to see this machine tool with a beautiful appearance. You can buy it: Beautiful is just a floating cloud, as long as you are willing to spend money, no matter how beautiful it is. This is a misconception. B:
This machine tool is so slow, only 5, 60 square meters, I can't buy it The article clearly tells you that this is also a misunderstanding. Speed can be restored.
Misconception c:
This machine tool has poor accuracy and a major issue, so it cannot be purchased The article clearly tells you that this is also a misunderstanding. Accuracy can also be restored.
These will be discussed in depth in the second layer, so what is the most important point of buying a second-hand machine tool?
Two words: stable
When you buy a stable machine tool, and then sort out and repair the remaining small problems of the machine tool, you can do things for you seriously, instead of constantly breaking down here and there, adding endless troubles to you
Suggestion 3: The most important thing when buying a second-hand machine tool is to ensure its stability
5： Dry Goods Point - Which machine tools are currently stable in the market?
In our current domestic market, there are many stable models (including many unstable ones), such as the 240CC 440CC from Shamir, the AQ series from Shadik, the FA and MV series from Mitsubishi, the S and A series from the West, and the Qinghong Litong from 2006 onwards. These are all more stable machine tools than others
Suggestion 4: Try to buy stable machine tools as much as possible.
6： Dry Spot - I bought a stable machine tool as you mentioned, why is it still prone to breakage?
Due to the lack of systematic organization and maintenance, the current machine tools on the market, whether purchased directly from manufacturers or second-hand merchants, are generally ready to use by users without systematic organization. The following problems exist:
1. There are many small problems with the machine tool itself, which can cause inconvenience in processing, such as threading, water spraying, poor sensing, and so on
2. The electrical control department has not undergone systematic organization, resulting in a lot of dust. After being transported and loosened, it blows everywhere, causing frequent damage to the electrical board due to moisture regain.
3. The electronic control department, vulnerable parts, contact switches, fans, and electronic components that are nearing their lifespan have not been replaced, resulting in frequent damage and frequent machine tool malfunctions
4. In the water tank section, there is usually a thick deposit of dirt, which can easily block pipes, solenoid valves, etc. after loosening during transportation, leading to many small problems and continuous malfunctions
There are also many problems that accumulate in the mechanical department, sensing department, refrigeration department, and so on, leading to frequent machine tool malfunctions that seriously affect usage.
According to the knowledge of the editor, currently in the Chinese market, users do not have the concept of systematic organization for second-hand machine tools, resulting in continuous machine tool failures and a negative impression of second-hand machine tools among many users.
Suggestion 5: For the purchased machine tool, try to hire professional maintenance personnel to organize the system and restore various functions of the machine tool. This will help you avoid worrying about the failure rate of this machine tool for the next few years.
7： How to choose whether to use immersion or spray?
Relatively speaking, immersion type machine tools are generally more expensive than water spray type machine tools. If the machine is processing workpieces with a common thickness of T50mm or less, choose the water spray type. If the machine is processing workpieces with a relatively high thickness, such as frequently processing workpieces with a thickness of T80mm or more, an immersion type machine tool must be selected
8： Is it purchased from second-hand merchants or manufacturers?
It doesn't matter, some people avoid second-hand merchants and worry about how much they make. In fact, this is not a problem. If you buy a bottle of water, you also buy it from a supermarket, and the supermarket needs to earn you a few cents, allowing others to make reasonable profits. This is normal, after all, second-hand merchants have access to most of the resources and information.
On the contrary, machine tools directly produced by manufacturers may not necessarily be good, and it is still up to everyone's experience and vision to see.
Suggestion 6: Everything should be based on the stability of the machine tool. It is not important where to buy it, and the price is not important at all. What is important is that the machine tool can stably produce for you in the next few years, which is the top priority.
9： This machine tool has been refurbished and I dare not buy it
Some second-hand merchants may renovate the appearance of machine tools in order to make them look beautiful, which makes many friends hesitant to buy them.
In fact, as long as you master some of the principles mentioned earlier, it doesn't matter. If a lot of paint falls off the appearance of the machine tool, do you still need to repair it when you take it home?
10： Would you like to choose a Swiss brand, Japanese machine tool, or Taiwanese machine tool?
Relatively speaking, Swiss and Japanese machine tools have higher accuracy and better turning angles compared to Taiwanese brand machines. Of course, the price will also be higher. You can decide according to your own needs, and what meets your needs is the right one.
