Although the price of machining technology does not fluctuate much according to the market, its calculation method will also change according to the addition of external conditions such as different times, regions, national policies and so on.
Detailed quotation method of machining process
1. The calculation of process time is required for each key or complex part.
2. Understand the price of working hours in the local market, and calculate the processing cost according to the hourly cost of equipment. For example, for specific equipment, ordinary vertical equipment is between 60-80 yuan, and ordinary equipment such as milling machines and ordinary cars is 30 yuan.
3. After calculating the cost, we should add the packaging and transportation expenses, management expenses, profits, taxes, etc. in a certain proportion, which is the actual price we can quote. However, to a certain extent, the actual price is also closely related to the purchase volume of parts and the size of production batches.
The quotation of processing technology has certain flexibility, that is to say, a part may have different quotations, mainly considering that the process arrangement that may be used to process the same part is different, so the cost will also be different. However, sometimes you often encounter a complex process arrangement with a high quotation, and the simple process is used in the actual operation. At this time, the purchaser's ability in parts processing, drawing analysis and so on is required. Therefore, it is also very important to train buyers in machining knowledge.
Rough quotation method of machining process
If you need to process a workpiece, you should first record the material cost and the travel expenses of purchasing the workpiece. Then determine the working hours required for processing the workpiece according to the processing technology. At present, the price of working hours in the market is 10-15 yuan / hour for fitters and 10-20 yuan / hour for general lathe workers. If the processing is complex and there is no ready-made tools and equipment, the purchase price and need to be recorded separately.
In addition, machine depreciation costs, labor costs, management fees, taxes, transportation costs, etc. need to be calculated. Some enterprises will also include business expenses in the quotation, so for the quotation staff, they need to have a deep understanding of the market. If they are not careful, they will reduce their profits due to the lack of one item.
The processing cost should also be included in the process problem (the processing cost is different for different processing methods). The main thing is to determine the process, that is, the processing method we call, and then calculate the company according to the process. The basic processing cost of a single part is determined by the working hours, plus other costs.
The quotation of machining process is a complex system. For the bidder, every quotation is a challenge. It is not only necessary to make a reasonable quotation according to the specific conditions of processing, but also to maximize the profits of the enterprise. Therefore, there are still many things to learn for the quotation staff of machining.
