What website to buy machining center

1. The key to purchasing a machining center is to estimate the future machining demand by comprehensively considering the current process requirements and processing capacity, including the following factors: rapid machining feed, rigidity and accuracy, extension axis and maintenance technical support. Fast machining feed can obtain the best combination of spindle power, torque and speed, users do not need to blindly pursue the highest spindle speed to obtain the ideal feed speed. In most cases, the balance between spindle torque and speed is determined by the blank material and the amount of metal removed ring rough machining. The machining center with spindle speed of 10000-15000r / min can meet 70% - 80% of the mold processing requirements. It is also very useful to rely on program processing and control software specially designed for mold processing
with the continuous heating of the random bed, the increase of heat will seriously affect the machining accuracy and maintain a stable part tolerance. The high-speed spindle needs to use air / oil lubrication coating on the spindle bearing to rece the friction at the same time. Therefore, the spindle can keep running at low temperature for a longer time. Because the coefficient of thermal expansion of ceramic is only 1 / 3 of that of steel, ceramic bearing should be used instead of steel bearing
in addition, selecting a machining center equipped with an extended turntable device (such as five axis machining) can significantly control the cost of machine purchase and rece the number of clamping, which not only improves the utilization rate of machine tools, but also increases the scalability
finally, before purchasing a machine tool, you should consult your peers about the reliability of the selected machine tool, and pay attention to the technical support level of the brand, the supply of spare parts, and the cost of machine tool renovation and upgrading

2. Drill and attack, more than 200000, or engraving and milling machine, 160000-170000, interested in leaving a number for you to recommend

3. Man, I'll calculate the cost for you. The more the Dell Ling is a low-end entry-level model, the more the power consumption is 100W. The power consumption is about one yuan per hour in 10 hours and one yuan per hour in the city. You dig for 12 hours, and the power consumption is 1.2 degrees. I don't know what kind of currency you dig. Judging from the quantity, it must be a cheap counterfeit currency. A currency may be about 0.0002-0.2, mining is very harmful to the graphics card. After mining, the graphics card can only live for 3-6 months. The notebook manufacturer who is damaged by mining defaults that it is artificially damaged and will not be repaired. The Dell Lingyue is about 4000 yuan. You have to lose 1 yuan per day in electricity bills and notebook loss fees. The 4000 fast notebook can only be used for half a year, and you don't make money. You have been losing money. Pure hand fight, please adopt!

4. You should know which upstream customers will need your processing services, and then talk about them one by one

5. Now online to buy processing center, if you want to be reliable, you can find the network

6. Unknown_Error

7. Domestic and imported procts are different. For example, domestic procts are about 850-25w, Taiwan's 35W, Japan and Germany's 70-80w. Each grade is different, the key depends on what you do, and whether you want to be vertical or horizontal. I do this. If you are interested, you can leave a contact information or email or something. I can communicate with you and analyze it.

8. Is it a foreign trade order? Go to Alibaba. Our company is also in the above orders, orders are done

9. Network promotion, 360 promotion is the most direct. The others are not so good
