1、 Precision selection of high-speed punch: as the saying goes, "don't get porcelain work without diamond drill", "if you want to do good work, you must first sharpen the tools". The market demand is increasingly fierce. If a company wants to keep the development trend and improve its competitiveness, we should not only save the cost, but also improve the product quality. To produce a qualified product, it may be possible to guarantee the general punch, but if all goods are of high quality, we need to purchase high-speed punch with high precision.

The key factors of punch accuracy are: 1. Parallelism, 2. Perpendicularity, 3. Total clearance. Only in this way can we ensure that the dynamic dead point is within the difference value, promote the production of every commodity to meet the standard, and spare parts in the mold will not be damaged. The precision of punch press is comparable with that of Japanese punch press. The special machining technology enables the crankshaft to maintain its true roundness. Therefore, the parallelism of the upper and lower fixed points is extremely accurate. It is not only the bottom dead point, but also can not be guaranteed by the same industry. High precision punch not only can produce good products, but also has less damage to the mold, which not only saves the mold maintenance time, but also saves the maintenance cost.

2、 Speed selection of high-speed punch: there are two kinds of punch in Taiwan and China, one is the highest speed of 400 times / min, the other is 1000 times / min. If your commercial mold requires a speed of 300 times / min or higher, you should choose 1000 times / min punch. Because the equipment can not be used to the limit, and there is no forced lubrication system in the press within 400 times / min, only grease lubrication is used in the bone joint. And the structure of the punching needle is slider type, the precision can not be guaranteed, in the long-term work, the damage is rapid, the precision is reduced, the mold is easy to damage, the equipment and mold maintenance rate is high, and the delay time, endanger the delivery time. For example, the maximum speed of Huitian punch in Jiangsu Province is 1000 times / min, which can well consider your speed requirements. The three circle locating pin punch press system has good precision and heat resistance, and basically no wear under the forced grease.

3、 Appearance structure of high speed punch: high quality structure can ensure the accuracy of the equipment. The appearance and structure of the press has become an imitation in the industry. Punch foot is the basic part of the machine, and some brands of punch in the same tonnage, foot in the same tonnage is not big. The shell is the guarantee of the precision of the machine. The shell of the punch press is forged by Sadik enterprise of Japan. The crankshaft and the key connecting steel are all imported from Japan. SKF Bearing made in Sweden is adopted as the bearing. In order to improve the (dynamic) accuracy in stamping work, the punch press adopts the elastic yellow balance system behind the slider, while some brands of punch presses do not have this arrangement. The punch adopts frequency conversion speed regulating motor, which has low function loss. Under the same tonnage, the high-speed punch can save 30% power
