1. First, let's talk about the ordinary hydraulic bending machine, also known as a non-CNC bending machine, which we commonly refer to as a conventional machine. Generally, machine tool manufacturers can produce various types of CNC bending machines now, but the quality of conventional machines can significantly represent whether a company has ingenuity.
2. Enterprise scale directly affects after-sales service. You cannot expect a small company with only a dozen employees to provide immediate after-sales service. A formal and healthy enterprise operates with clear division of labor. You can trust products from such enterprises. How to measure the scale of an enterprise? I usually advise clients to visit the factory directly. The legitimacy and efficiency of production in an enterprise are clearly visible.
3. The first two points mentioned are general and not directly related to the machines. Next, we will discuss the quality of the machines. When you are not very familiar with a bending machine, how do you make comparisons? Firstly, consider the size and weight of the machine. The main material used in a machine is steel. Machines with a larger size and heavier weight generally have better quality and sturdiness.
4. Secondly, consider precision. To truly understand the precision of a machine, you need to bring your own workpiece to test on the machine in the factory. However, this is usually not feasible. Factors affecting the precision of a machine include the backgauge, beam strength, and molds. Machines with chain-driven backgauges lack precision. Aluminum beams may look nice but can deform easily. High-quality machines are equipped with ball screw rods and linear guides. The strength and thickness of the beam are directly related.
5. Now, let's talk about the molds. If we compare the machine to a soldier, the mold is the soldier's weapon. Without good weapons, you cannot win fights. How can you differentiate between good and bad molds? Firstly, consider the material. 42CrMo is currently a very good material for bending machine molds, and other materials like Cr6W2Si are also good. For materials, ordinary users may not be able to distinguish them for some time. Generally, molds undergo high-frequency quenching, where only the blade is heat-treated. However, high-quality molds undergo full-body heat treatment, which is characterized by a hole on the mold, a clear indication of full-body heat treatment. The production cost of full-body heat-treated molds is significantly higher than that of blade heat-treated molds.
