How to order and quote for mechanical parts processing?

Whether it is mechanical parts processing, aerospace parts processing, medical automatic component processing, non-standard parts processing, etc., it is basically processed with drawings and materials. Of course, it can also be designed and customized.

First you have to look at the dimensions on the drawing. Remember that most drawings generally give the finished size, unless there is a special indication that it is a rough drawing. After looking at the size, look at the drawing to see the general shape of the finished part, what shape it is. A simple example:

If the part is a revolving body, it needs to be processed by a lathe; if the part needs to be swept, it needs a milling machine and a planer.

Look at the views in other directions of the drawing and the enlarged cross-sectional view, and pay attention to whether there are precise dimensions. If there are precise dimensions, it needs to be finished. For example, some outer circles may have to cooperate with other holes or be in a friction state for a long time, then an outer cylindrical grinder is required to grind them to achieve a good surface roughness.

As for which factory can manufacture and process such parts, it depends on the processing capacity of the unit. Some machining units are good at finishing, some machining units are capable of large-scale processing, and some machining units The unit is suitable for batch processing.

About how to receive orders for mechanical parts processing, first of all depends on whether your industry feels very remote, but also depends on the importance of competitors.

For example, if you are processing parts for oil production equipment, you must have a very clear analysis and a clear understanding of where your customers are positioned. Because oil extraction is mainly done by the state, you must have a certain normal relationship with government departments, so interpersonal relationships are very important, and of course your own brand is also very important. Doing a good job in interpersonal relationships and paying attention to your own brand is necessary for how to take orders.

Quotation for machining of mechanical parts:

For quotation, you must first have a market reference price, otherwise you will not be able to quote it, nor will you Know how much.

For example: what kind of bed is needed to process mechanical parts, and how many man-hours the processing will take, you have to know in your heart, and then you can calculate the approximate price by referring to the labor-hour price of the bed at the market price. Every company should have such a data accumulation.
