Application of hydraulic oil in injection molding equipment
At present, there are many kinds of hydraulic pumps in injection molding equipment, and the selection of hydraulic oil is more complicated due to the influence of power, speed, pressure, flow, metal material and other factors. Generally speaking, HL oil can be used for low pressure pump, HM oil should be selected for medium and high pressure pump. The order of the effect of lubrication (anti-wear) of hydraulic oil on the three major pumps is vane pump > plunger pump > gear pump. The hydraulic system of vane pump as the main oil pump should choose HM oil regardless of its pressure

What are the characteristics of vertical milling machines?
Compared with horizontal milling machine, the main difference between vertical milling machine and horizontal milling machine is that the spindle is arranged vertically. In addition to the different arrangement of main shaft, the worktable can be up and down. The milling cutter used in vertical milling machine is relatively flexible and has a wide range of application. End mill, cutter head and drill bit can be used. It can mill keyway, milling plane, boring hole, etc. Horizontal milling cutter can be used as the main tool

Analysis of CNC machine tool industry in China
Due to historical reasons, China's machine tool industry more than 1000 enterprises in the domestic industrial layout convergence, resulting in a large amount of production, low-level repeated construction is serious, it can be said that problems occur frequently, but overall speaking, the prospect of China's data industry is still good, the following analysis of China's CNC machine tool industry. At present, due to the high level of machine tool purchasing among countries in Europe, there is a high level of inter regional development of machine tools

Effective protection of machine tool equipment
An important electrical parameter of machine tool is the effective power of motor. Using Phoenix Contact's contactron motor manager, this parameter can be accurately monitored, and high overload and low load operation can be detected by this instrument immediately. Because the motor manager can send out alarm and maintenance prompt in time before the motor breaks down, it can effectively protect the machine tool
