Detailed calculation method:

1）首先你可以对关键或复杂零件要求对方提供初步的工艺安排，详细到每个工序，每个工序的耗时

1) first of all, you can require an initial process for the key or complex parts, detailed to each process, and the time consuming of each process.

2）根据每个工序需要的设备每小时费用可以算出加工成本。 具体设备成本你也可以问供应商要，比如说，

2) the cost of processing can be calculated according to the cost per hour of the equipment needed in each process. You can also ask the supplier for specific equipment costs, for example,

普通立加每小时在￥60~80之间（含税） 铣床、普车等普通设备一般为￥30。。。

Ordinary Lijia per hour in between $60~80 (including tax) ordinary milling machine, car and other general equipment for $30...

3）在按照比例加上包装运输、管理费用、工装刀具、利润就是价格了

3) in proportion to the proportion of packing and transportation, management costs, tooling tools, profit is the price

当然，价格一定程度上会和该零件的年采购量和难易程度有很大关系。

Of course, the price to some extent will be related to the annual purchase and difficulty of the parts.

单件和批量会差很多价格，这也是很容易理解的。

It is easy to understand that a single piece and a lot will be a bad price.

粗略估算法：

Rough estimation method:

1）对于大件，体积较大，重量较重。

1) for large pieces, the volume is larger and the weight is heavier.

难度一般的： 加工费用大概与整个零件原材料成本之比为1：1，这个比与采购量成反比；

The difficulty is general: the ratio of the processing cost to the raw material cost of the whole part is 1:1, which is inversely proportional to the purchase quantity.

难度较大的： 加工费用大概与整个零件原材料成本之比为1.2~1.5：1，这个比与采购量成反比；

More difficult: the ratio of processing cost to the raw material cost of the whole part is 1.2~1.5:1, which is inversely proportional to the purchase quantity.

2）对于中小件

2) for small and medium parts

难度一般的： 加工费用大概与整个零件原材料成本之比为2~3：1，这个比与采购量成反比；

The difficulty is general: the ratio of the processing cost to the raw material cost of the whole part is 2~3:1, which is inversely proportional to the purchase quantity.

难度较大的： 加工费用大概与整个零件原材料成本之比为5~10：1，这个比与采购量成反比；

More difficult: the ratio of processing cost to the raw material cost of the whole part is 5~10:1, which is inversely proportional to the purchase quantity.

由于机械加工存在很大的工艺灵活性，也就是一个零件可以有很多种工艺安排，那么成本当然是不一样的，

Because there is a lot of process flexibility in mechanical processing, that is, a part can have many kinds of process arrangement, then the cost is not the same.

但是供应商有时会报价时给你说一种复杂工艺提高价格，而实际生产时会采用其他简单工艺，所以采购员自身

But the suppliers sometimes offer you a complex process to raise the price, while other simple processes are used in actual production, so the buyer himself

对图纸的阅读和对零件加工方面的知识的多少就决定你对成本的把握，所以机械零件采购需要比较全面的机械加工知识。

How much knowledge of drawings and parts processing determines your cost control, so mechanical parts purchase requires more comprehensive knowledge of machining.

机加工费用构成，一般按照工时给的！

The composition of the processing cost is generally given in accordance with the time of work.

如果你要加工一个工件，首先是对方的材料费用；然后是为了购买工件的一些差旅费用（一般没有）；

If you want to process a piece of work, first of all is the cost of the other's material; then it is to buy some travel expenses (generally not) for the job.

最主要的是你要加工的工件所需要的加工工时，一般车工10-20元/小时，钳工要少一点大概10-15/小时；其余不在例举；

The most important is the processing time to the processing of the workpiece you need, the general lathe 10-20 yuan / hour, fitter a little less about 10-15/ hours; the rest is not in the list;

如果没有现成的工具（如刀具、模具），所购买的费用也是需要你承担一部分的或全部；最后加起来就是你要付的加工费用！

If there are no ready tools (such as cutting tools and dies), the purchase cost will also take part or all of you. Finally, the total cost is the processing cost you need to pay.

材料费、机器折旧、人工费、管理费、税 等基本的是要的。或者是材料费、加工费和税，还有业务费用，运输费用，做预算需要多市场有一个很透彻的了解，不在其中摸爬滚打几年会完全摸不到头绪，就连我的老师也常常会感慨！一点不留心都不行啊！

Material fee, machine depreciation, manual fee, management fee, tax and so on are essential. Or is the cost of materials, processing fees and taxes, as well as business expenses, transportation costs, budget to market have a very thorough understanding, not in a few years will be fought completely out, even my teachers often sigh! Not a little careless!

工艺的问题了应该包括材料费、加工费（采用何种加工价钱就不一样了）、设备折旧费、工人工资、管理费、税等。主要是先确定工艺，即加工方法，然后根据工艺来计算工时，由工时来确定单个零件的基本加工费用，再加上其他的费用。工艺是个很复杂的学问啊 一个零件采用不同的工艺，价格有差异的 附，各个工种加工工时基本价 其实各种工种的工时价格并没有固定的,会根据工件的难易,设备的大小,性能的不同而不同,当然关键的有看你的量是多少了,不过一般来说它都有一个基本价,在基本价之间浮动.
