Why are the quotations so different for CNC machining?

The processing of aluminum alloy parts and hardware parts is generally carried out through CNC machining, but because the entry threshold of CNC machining is low, there are many small CNC machining workshops on the market, and the uncertainty in price and quality is also caused. Today, let’s take a look at how to grasp the price of hardware parts processing, so that you can find a hardware parts CNC processing factory with quality assurance but not too expensive.

　　 Looking for a suitable CNC processing factory

Each manufacturer has its own advantages. Small factories are suitable for proofing, and large factories are suitable for large quantities. We need to find a suitable CNC processing factory according to our own needs, generally according to the length of product processing time, or according to machine tools For example, your product can be made with a lathe, but you have to find a machining center to do it. It must be a lot more expensive. The quotes in the industry are also very different and very complicated. One is higher than the other. I want to find It’s better not to find a store if you are guaranteed, you should find a physical factory. As far as I know, the factory that specializes in external processing is also very expensive. It is best to find the kind of factory that processes for yourself but also processes externally. They are cheap and quality. Guaranteed.

　　How to calculate the price of hardware parts processing

　　1, first look at your drawings and technical requirements

　　 2. There are differences in materials and labor in different places, and the price difference in some places is huge

3. General parts are calculated based on material cost + processing cost + profit. The processing cost depends on the process. Of course, the price of using different processing equipment is different and some are calculated by working hours (turning time, grinding time, etc.) , And some are calculated according to the process (such as how much is a folding knife, how much is a normal drilling, etc.)

4. There is also the problem of quantity. Of course, large quantity is cheap. If it is a single piece, it will be miserable. Even if it is a small piece, the material is not retail, and the price of the whole board is counted! For example, you said 0.3, which is not commonly used by manufacturers. If you only have one or two pieces, if you only buy one board at a time (for example, 1220*2440), then your material cost will be spent wrongly.

　　 5. The problem of the processing plant If the parts processing plant can handle it by itself, of course there is no problem. If the processing plant itself has some processes to be outsourced, the price will increase accordingly. If you are already an outsourcing agency, you have gone through two outsourcing sessions! So when you find a processing factory, you must also find the right one, find what they can do, and do it well.

　　Specific CNC machining price calculation:

　　 CNC lathe processing fee: The standard algorithm is working hours * wages per working hour + fixed expenses that should be apportioned, such as depreciation expenses. General CNC machine tool processing fee is 60 yuan per hour. The machine is about 1 meter, ordinary Lijia machine. Where there are few machine tools, the price will increase slightly by more than 10 yuan. Of course, the price will vary depending on the processing capacity of the machine.
