What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

Spring Design Attention And Roll Forming Method

Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

Calculation Methods for CNC Machining Quotation

Detailed calculation method:

1) First of all, you can ask the other party to provide preliminary process arrangements for key or complex parts, detailing each process and the time consumption of each process

2) The processing cost can be calculated according to the hourly cost of the equipment required for each process. You can also ask the supplier for the specific equipment cost, for example,

Ordinary Lijia is between ¥60~80 per hour (tax included). Ordinary equipment such as milling machines and general vehicles is generally ¥30. . .

3) In proportion to the packaging and transportation, management costs, tooling tools, profit is the price

Of course, the price will have a lot to do with the annual purchase volume and difficulty of the parts to a certain extent.

The price difference between single piece and batch is very easy to understand.


Rough estimation method:

1) For large items, the volume is larger and the weight is heavier.

General difficulty: The ratio of the processing cost to the cost of the raw materials of the entire part is about 1:1, and this ratio is inversely proportional to the purchase amount;

More difficult: The ratio of the processing cost to the cost of the raw materials of the entire part is about 1.2~1.5:1, this ratio is inversely proportional to the purchase amount;


2) For small and medium items

General difficulty: The ratio of processing cost to the cost of raw materials for the entire part is about 2~3:1, and this ratio is inversely proportional to the purchase amount;

More difficult: The ratio of the processing cost to the cost of the raw materials of the entire part is about 5-10:1, and this ratio is inversely proportional to the purchase amount;

Because precision machining has great process flexibility, that is, a part can have many kinds of process arrangements, so the cost is of course different.

However, sometimes the supplier will tell you a complicated process to increase the price when quoting, and other simple processes will be used in actual production, so the buyer himself

The reading of the drawings and the knowledge of parts processing determines your grasp of the cost, so the purchase of precision machining parts requires a more comprehensive knowledge of precision machining.

The composition of machining costs is generally based on working hours!

If you want to process a workpiece, first it is the material cost of the other party; then some travel expenses to purchase the workpiece (generally not);

The most important thing is the processing man-hours required for the workpiece you want to process, generally 10-20 yuan/hour for lathes, and about 10-15/hour for fitters; the rest are not listed as examples;

If there are no ready-made tools (such as knives, molds), you need to bear part or all of the cost of the purchase; the final total is the processing cost you have to pay!


Material costs, machine depreciation, labor costs, management fees, taxes, etc. are basically required. Or material costs, processing fees and taxes, as well as business costs, transportation costs, and budgeting. You need a thorough understanding of the market. If you don't do it for a few years, you won't be able to figure it out at all, even my teacher. I often sigh with emotion! Not paying attention at all!


Process issues should include material costs, processing fees (which processing prices are different), equipment depreciation fees, worker wages, management fees, taxes, etc. The main thing is to first determine the process, that is, the processing method, and then calculate the man-hours based on the process. The man-hours determine the basic processing cost of a single part, plus other costs. Craftsmanship is a very complicated science. A part adopts different crafts, and the price is different. The basic price of processing hours for each type of work is actually not fixed. It will be based on the difficulty of the workpiece, the size of the equipment, and the performance. Of course, the key depends on your quantity, but generally speaking, it has a basic price, which fluctuates between the basic prices.


1. The basic price of the car: 20-40. The specific ones are determined according to the actual situation. Like small parts, the simple working hours are less than 20 yuan; sometimes even only 10 yuan, such as some large pulleys, the processing margin is large, and the boss only earns The money for cast iron powder is enough; sometimes if the workpiece is large, it can be higher if it is generally impossible to process on the market, two or three times, and others can't help it.

2. Basic price of grinding: 25-45

3. Basic price for milling: 25-45

4. Basic price of drill: 15-35

5. Basic price for planing: 15-35

6.The basic price of wire cutting: 3-4/900 square millimeters

7. The basic price of EDM: 10-40, a single piece is generally 50/piece (less than 1 hour)

8.CNC basic price: it is 2-4 times more expensive than ordinary ones
