1. Pick the right model
For the first purchase of a small advertising sign shop, it is mainly used for crystal characters, three-dimensional character light plates, two-color plates and badges, etc., advertising grade should be purchased, but the equipment should be further refined. If two-color plates are first used, It needs to be equipped with a floating cutter head. Because it can ensure that the depth of the lettering is the same when engraving on the large-format two-color board, but if it is used for sawing plexiglass crystal lettering, it is necessary to choose a high-power spindle with greater than 800W.
2. Try before buying
Before buying a CNC engraving and milling machine, in order to ensure that your investment can be recovered, you should let the salesperson or the customer do it yourself to conduct experiments on the tasks that are often required to be done. At the same time calculate efficiency, investigate experimental results, and fully test the function of the machine.
3. Sign the contract
After acknowledging the purchase, the first task is to sign a contract with the seller. The contract must indicate the purchased model, equipment, delivery time, price, method of delivery, warranty terms, training methods, and payment methods.
Vertical machining center chooses hard rail or linear rail
Many people can't tell whether a machining center is a hard track? Is it better to have a linear track? So which one is better? If you want to know, let's get to know it with the editor!
In fact, there is nothing good or bad about hard rails and linear rails, they can only be said to be suitable or not, because their focus is different.
1. Advantages and applications of hard rail:
The hard rail has a large sliding contact surface, good rigidity, strong shock resistance, strong load-bearing capacity, and is suitable for heavy-duty cutting.
The hard rail is dry friction. Due to the large contact surface, the friction resistance is also large, and the moving speed cannot be too fast. At the same time, crawling is easy to occur, and the gap on the moving surface will cause machining errors. The maintenance of the machine tool track is the top priority. Once the track is not sufficiently lubricated, it will cause the track to burn or wear out, which is fatal to the accuracy of the machine tool.
The application of hard rail is suitable for heavy cutting, large molds, high hardness workpieces, and workpieces with general accuracy requirements.
2. Advantages and applications of linear rails:
Nowadays, the running speed of many machine tools is extremely fast, especially the idle speed. This is largely due to the credit of the linear rail; the linear rail can be pre-tensioned to achieve zero gap between the rails with high accuracy; in terms of service life, the linear rail The rail is much higher than the hard rail.
The cutting force of the linear rail is smaller than that of the hard rail. It is only for the hard rail. In fact, the linear rails of many machine tools have greatly improved their carrying capacity.
The application of linear rail is suitable for high-speed machines, high-speed cutting, suitable for processing products and small precision molds. Nowadays, more machining centers use linear rails.
