Detailed calculation method:

1 First of all, you can ask the other party to provide the pre-process arrangement of key or complex parts, detailing each process and the time consumption of each processudFYoYike manufacturer company

2 The machining cost can be calculated according to the hourly cost of the equipment required for each process. You can also ask your supplier for specific equipment costs, for example,udFYoYike manufacturer company

Ordinary cnc 60~80 yuan per hour.udFYoYike manufacturer company

3 Proportional to packaging and transportation, management costs, tooling tools, profit is priceudFYoYike manufacturer company

Of course, the price will have a lot to do with the annual procurement volume and difficulty of components to a certain extent.udFYoYike manufacturer company

The price difference between single and bulk is easy to understand.udFYoYike manufacturer company

Rough estimation method:udFYoYike manufacturer company

1 For large items, the volume is larger and the weight is heavier.udFYoYike manufacturer company

General difficulty: The ratio of the machining cost to the raw material cost of the entire part is about 1:1, and the ratio is inversely proportional to the purchase amount;udFYoYike manufacturer company

Difficulty: the ratio of the machining cost to the raw material cost of the entire part is about 1.2~1.5:1, which is inversely proportional to the purchase amount;udFYoYike manufacturer company

2 small and medium itemsudFYoYike manufacturer company

General difficulty: The ratio of the machining cost of the entire part to the raw material cost is about 2~3:1, and the ratio is inversely proportional to the purchase amount;udFYoYike manufacturer company

More difficult: the ratio of machining cost to the raw material cost of the entire part is about 5-10:1, and this ratio is inversely proportional to the purchase amount;udFYoYike manufacturer company

Because precision machining has great process flexibility, i.e. a part can have multiple process arrangements, the costs are of course different.udFYoYike manufacturer company

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

The reading of drawings and the knowledge of parts CNC machining determine your grasp of the cost, so purchasing precision machined parts requires more comprehensive precision machining knowledge.udFYoYike manufacturer company

The composition of CNC machining costs is generally calculated by working hours!udFYoYike manufacturer company

If you want to process a workpiece, the first is the material cost of the other party; then some travel expenses for purchasing the workpiece (generally not);udFYoYike manufacturer company

The most important thing is the CNC machining hours required for the workpiece you want to machineudFYoYike manufacturer company

If there are no off-the-shelf tools (eg knives, molds), you are responsible for some or all of the purchase cost; the final sum is the disposal fee you have to pay!udFYoYike manufacturer company

Material costs, machine depreciation costs, labor costs, management fees, taxes, etc. are basically required. or material costs, CNC machining charges and taxes, as well as business costs, shipping costs and budgets. You need to have a thorough understanding of the market. I haven't done it for a few years, and even my teacher can't figure it out. I always feel emotional! Didn't notice at all!udFYoYike manufacturer company

Process issues should include material costs, CNC machining costs (which CNC machining price is different), equipment depreciation costs, worker wages, management fees, taxes, etc. The main thing is to first determine the process, that is, the CNC machining method, and then calculate the working hours according to the process.udFYoYike manufacturer company

Man-hours determine the basic CNC machining cost of a single part as well as other costs. Crafting is a very complex science. Some of them use different craftsmanship and have different prices. The base price of CNC machining time for each job is actually not fixed. It will depend on the difficulty of the workpiece, the size and performance of the equipment.udFYoYike manufacturer company

Of course, the key depends on your quantity, but generally, it has a base price and fluctuates between base prices.udFYoYike manufacturer company
