CNC four axis machining, as the name suggests, is an addition of one axis to the three axis CNC, so that the processing of multiple processes can be completed in one clamping process. However, four-axis are generally used in places where three-axis machine tools cannot or are difficult to process, such as parts that cannot be processed by depth and angle limits. At present, products such as worms, fan blades, etc. are common. Using four-axis CNC to process such products is more Three-axis CNC machining efficiency and accuracy are higher.
SCZY has many three-axis, four-axis, five-axis CNC milling machines, as well as lathes, grinders, EDM, wire cutting and other equipment, which can meet the different requirements of different customers. The highest precision we can achieve is ±0.002mm (specifically Depending on the product material and structure), the materials we process include steel, iron, copper, aluminum and plastic materials, etc. Our products are widely used in navigation, aviation, automobile, machinery, equipment, automation, mold accessories and so on.

1. Insufficient oil quantity of the engine oil reduces the pump oil quantity of the oil pump or the pump does not oil due to air intake, resulting in a drop in oil pressure;
2, the engine temperature is too high, it is easy to thin the oil, from the loss of a large number of gaps with the resulting pressure drop;
3. When the parts of the oil pump are damaged or the clearance is too large due to problems such as wear and assembly, the oil pump will not cause oil or oil shortage.
4. The mismatch between the crankshaft and the large and small tiles is improper. If the tightening is too tight, the oil pressure will increase, and the looseness will reduce the oil pressure.
5, the oil sensor is damaged, the oil filter, suction oil blockage will also reduce the oil pressure;
6. Damage or failure of oil return valve: If the main oil return valve spring fatigue is softened or improperly adjusted, when the mating surface of the valve seat and the steel ball is worn out or gets stuck by the dirt, the oil return amount will increase significantly. The oil pressure of the main gallery will also decrease.
7. If the oil is improperly selected, if the wrong or improper grade is selected, the engine will run at an excessively low viscosity to increase the leakage, thus reducing the oil pressure.
