Second-hand punches are very useful, you can also find suitable second-hand punches if you master these points

When many people started to set up a metal stamping factory, they usually chose to buy second-hand punching machines due to their limited funds and customer resources. Although it is called a second-hand punch, no one can determine the actual number of hands. Let's call the old punches collectively second-hand punches. Second-hand punches are not like new punches. They have been strictly inspected when leaving the factory, so you must carefully screen them when choosing a second-hand punch. Today, stamping will share with you a few points that you need to pay attention to when choosing a second-hand punch: 1. Brand. In the hardware stamping industry, the unified understanding is that the punches of big brands are better than those of small factories if the quality is better. Because many small factories now greatly reduce materials in order to reduce costs when producing punching presses. This can be easily distinguished by the weight of the punch. Second, the factory time. Any mechanical equipment has a useful life, and punching machines are no exception. Since the second-hand punch has been used for a period of time, the service life will be reduced accordingly. Try to avoid buying punches that have been out of the factory for too long. Three, maintenance history. If the second-hand press has undergone major repairs, the corresponding accessories are no longer the original accessories, and the stability and accuracy will be greatly reduced. Try not to buy this type of second-hand press. When purchasing a second-hand punch, be sure to carefully check whether the key components are different from the old or new body. In fact, if the second-hand punch is purchased properly, not only can the cost be greatly reduced, but also because the second-hand punch has passed the running-in period, it also has a good performance in terms of performance. As long as we are buying second-hand punches and ask more questions, we will definitely be able to choose a satisfactory punch.
