Comptabilité et devis des pièces de tournage CNC

Coût et devis des pièces tournées
Le coût des matériaux d’usinage est certain. La principale différence réside dans les coûts de main-d’œuvre différents de chaque entreprise, les coûts de transport, coûts de consommation, et les impôts. Donc ces pièces usine d'usinage CNC de quelle manière elles sont calculées principalement par?
Ce qui suit est une compilation d'une partie des données de tournage CNC pour référence (car le mode de calcul varie en fonction du prix de chaque place).
La méthode de calcul détaillée du tournage CNC:
1) Tout d'abord, vous pouvez demander au fournisseur de fournir des arrangements préliminaires pour le processus de tournage CNC pour les pièces clés ou complexes, détaillant chaque processus et la consommation de temps de chaque processus.
2) The processing cost can be calculated according to the hourly cost of the equipment required for each process. You can also ask the supplier for the specific equipment cost, Par exemple: Ordinary end milling CNC machining is at ￥60~80/hour (tax included); Common equipment such as milling machine and general turning is generally ￥30/hour.
3). Add packaging and transportation, management costs, tooling, turning tools, and profit in proportion to the price. Bien sûr, to a certain extent, the price will have a lot to do with the annual purchase volume and difficulty and ease of the parts. The price difference between a single prototype and a large batch is very easy to understand.

Rough estimation method for CNC turning parts:
1) For large workpieces, the volume is larger and the weight is heavier.
General difficulty: The ratio of the processing cost to the cost of the raw materials of the entire part is about 1:1. This ratio is inversely proportional to the purchase volume;
Complex turning workpieces: The ratio of the processing cost to the raw material cost of the entire part is about 1.2~1.5:1. This ratio is inversely proportional to the purchase volume;
2) For small and medium turning workpieces
General difficulty: The ratio of CNC machining cost to the cost of the entire part’s raw materials is about 2~3:1. This ratio is inversely proportional to the purchase volume;
Difficult and complex parts: The ratio of the processing cost to the raw material cost of the entire part is about 5-10:1. This ratio is inversely proportional to the purchase volume;

Because machining has great process flexibility, c'est, a part can have many kinds of process arrangements, the cost is of course different. Cependant, sometimes the supplier will tell you a complicated process to increase the price when quoting, while other simple processes will be used in actual production. Donc, the purchaser’s own understanding of the drawings and CNC machining knowledge of parts determines your cost control. Donc, the purchase of mechanical parts requires comprehensive CNC machining knowledge.

1. Basic price for turning: ￥20-40/hour
The specifics depend on the actual situation. Like small items, the simple working hours are less than ￥20/hour; sometimes even only ￥10/hour.
Par exemple, for some large pulleys, CNC machining has a large margin, and manufacturers can make a profit as long as they earn money from waste powder;
Sometimes if the workpiece is large, the general factory cannot process it, so you can quote a higher price two or three times higher, and the customer has no choice.
