What is the difference between old and new milling machines and how to choose them?

When customers want to buy milling machines, they often tangle about whether to buy new milling machines or second-hand old milling machines or refurbished milling machines. In fact, they don’t have to tangle too much. This problem is easy to solve.

If a new factory needs a milling machine, and there are also no other milling machines in the factory. If you are a novice operator, I recommend you buy a new milling machine. First of all, during milling machine model selection, the professional sales person will give some reasonable suggestions according to your processing needs and help you recommend the suitable milling machines. Secondly, the new milling machine will undergo strict performance testing before leaving the factory. If there are little small problems, the technicians will help you solve them before delivery. Trial processing service can also be provided. You can send the workpiece to be processed to our factory. We can invite professional technicians to carry out trial processing, and take photos and videos for machining information feedback. Finally, the new milling machine has perfect after-sales service and technical support to solve your worries. The manufacturers selling new milling machines are generally formal and professional manufacturers. You basically don’t have to worry about any problems.

If you have a lot of milling machine equipments, have some experience in milling machine operation, and are familiar with all kinds of milling machines and the operation of all components. You needs a batch of rough processing milling machines, and at the same time there are some problems in capital, so second-hand milling machines are also a good choice. However, there are still some matters needing attention.

1. The second-hand milling machine has no after-sales service, and the milling machine is seriously worn. Small problems may occur in the later stage, and the maintenance cost will be high.
2. When purchasing second-hand milling machines, it is best to find a professional technical engineer to help you for any questions.

First, we should look at the appearance of the milling machine and check whether the shell of the milling machine is seriously deformed and whether the paint falls off seriously. Whether the milling machine has a nameplate, and whether the parameters and manufacturer of the nameplate are clear. Secondly, need to check the inside of the milling machine, check the wear of guide rail, gear, belt, whether hand wheel, pull rod and other accessories have and not bad. Third, check the manufacturer of the milling machine (the machines of some famous manufacturers are still trustworthy), the service life, and whether the main parts of the milling machine have maintenance or replacement records. Fourth, must check whether the details and performance are good. Whether each X / Y / Z axis crawls; Whether there is abnormal noise in the main spindle box and gearbox after the main spindle is started; Whether the spindle jumps; Whether the tool feeding and fast of the tool feeding box operate normally; must use a dial indicator to check the verticality of the spindle and worktable of the milling machine, and use a level to check the flatness of the milling machine surface and the parallelism with the spindle axis. Finally, need to ask a professional electrician to check the power supply, wire and control system (if purchasing CNC system milling machine) to ensure that there is no leakage; The oil circuit and signal switch shall operate stably without oil leakage and stable transmission. It’s best to try processing and testing.
