Detailed calculation method:
1) First of all, you can ask the other party to provide the preliminary process arrangement of key or complex parts, and explain in detail the time-consuming of each process.
2) The processing cost can be calculated according to the hourly cost of equipment required for each process. You can also ask the supplier about the specific equipment cost, such as:
Ordinary equipment such as milling machines and general cars with 60 ~ 80 hours (including tax) is generally 30. . .
3) Add packaging and transportation, management fees, tooling tools, and make a profit in proportion to get the price.
Of course, the price will have a great relationship with the annual purchase volume and difficulty of this part to a certain extent.
It is also easy to understand that there will be a big difference between single piece and batch.
Rough estimation method:
1) For large pieces, it is bulky and heavy.
The difficulty is average: the ratio of processing cost to the whole raw material cost is about 1: 1, which is inversely proportional to the purchase amount;
Difficulty: the ratio of processing cost to raw material cost of the whole parts is about 1.2 ~ 1.5: 1, which is inversely proportional to the purchase quantity;
2) For small and medium-sized parts
The difficulty is average: the ratio of the processing cost to the raw material cost of the whole part is about 2 ~ 3: 1, which is inversely proportional to the purchase volume;
Difficult: the ratio of the processing cost of the whole parts to the raw material cost is about 5 ~ 10: 1, which is inversely proportional to the purchase volume;
Because machining has great process flexibility, that is, a part can have many process arrangements, then the cost is of course different.
But suppliers sometimes tell you a complicated process to raise the price when quoting, but other simple processes will be used in actual production, so buyers themselves.
The reading of drawings and the knowledge of parts processing will determine your grasp of the cost, so the procurement of mechanical parts requires comprehensive machining knowledge.
The composition of processing expenses is generally given according to working hours!
If you want to process a workpiece, the first is the material cost of the other party; Then there are some travel expenses for purchasing workpieces (generally not);
The most important thing is the processing time of the workpiece you want to process. General Turner 10-20 yuan/hour, fitter is a little less, about 10- 15/ hour; The rest are not listed one by one;
If you don't have ready-made tools (such as knives and molds), you have to bear part or all of the purchase costs. Finally, it adds up to the processing fee you have to pay!
Material costs, machine depreciation, labor costs, management fees, taxes and other foundations are very important. Or the cost of materials, processing and taxes, as well as business expenses and transportation expenses. Budgeting requires a thorough understanding of many markets. If you don't stay in it for a few years, you won't get any clues at all. Even my teacher often feels sad! It's impossible to be completely careless!
Technical problems should include material cost, processing cost (which processing price is different), equipment depreciation cost, workers' wages, management fees, taxes and so on. Mainly to determine the process, that is, the processing method, and then calculate the working hours according to the process, and determine the basic processing cost of a single part by working hours, plus other expenses. Technology is a very complicated science. The technology used in a part is different, and the price is also different. In fact, the basic price of working hours for each type of work is not fixed, and it will be different according to the difficulty of the workpiece, the size and performance of the equipment. Of course, the key depends on your quantity, but generally speaking, it has a base price, which fluctuates between the base prices.
1. Basic car price: 20-40 depending on the actual situation, like small pieces, simple working hours are within 20 yuan; Sometimes even only 10 yuan, such as some big pulleys, has a large machining allowance, and the boss only earns enough money for cast iron powder; Sometimes when the workpiece is big, it can be a little higher, two or three times, and others can't help it. 2. Basic grinding price: 25-45.
3. Basic milling price: 25-45. 4. Basic drilling price: 15-35.
5. Basic price of planer: 15-35
6. Basic price of wire cutting: 3-4/900mm2. 7.EDM basic price: 10-40, 50 per piece (less than 1 hour).
8.NC basic price: 2-4 times more expensive than ordinary. 9. Sculpture: Generally it is a single piece. 50-500/ piece, of course, it is still a word. A specific price for a specific product. The above prices are for reference only. If you have any experience, I hope you can tell us and communicate with us.
