1, the oil is smooth:
Viscosity is an important characteristic of smooth oil; the viscosity of the powder directly affects the fluidity of the smooth oil and the thickness of the oil film formed by the conflicting surface; the viscosity of the smooth oil at the working temperature of the SKF bearing is usually 12-15 cst. The higher the rotational speed, the lower the viscosity; The heavier the load, the higher the viscosity should be. The commonly used smooth oils are mechanical oil, high speed mechanical oil, turbine oil, compacting oil, transformer oil, cylinder oil, etc.
The oil smoothing method includes:
a. Oil bath smooth oil bath smooth is the most common smooth method; suitable for the smoothness of low and medium speed bearings; part of the bearing is immersed in the groove; smooth oil is brought up by the rotating bearing parts; then it flows back to the oil groove. Below the middle of the lowest roll.
b. Smooth dripping oil is suitable for the quantitative supply of smooth oil to the bearing components; the amount of dripping is usually one drop every 3-8 seconds; too much oil will cause the bearing temperature to increase.
c. The circulating oil is smooth and the oil is pumped to the bearing parts; the smooth oil after the bearing is filtered and cooled, and then used. Because the circulating oil can take away a certain amount of heat; the bearing is cooled; therefore, the method is suitable for bearings with higher speed. component.
d. The spray is smooth and mixed with smooth oil by a sprayer to form an oil mist; in the eruption bearing; the air flow can effectively cool the bearing and avoid the intrusion of impurities. This method is suitable for the smoothing of high-speed, high-temperature bearing components.
e. The illuminating and sliding oil pump pumps the high-pressure oil into the bearing through the nozzle; the oil injected into the bearing flows into the oil groove through the other end of the bearing. When the bearing rotates at a high speed; the rolling body and the holding frame also make the ambient air flow at a suitably high rotation speed. It is difficult to send the smooth oil to the bearing in a generally smooth manner; in this case, the smooth oil must be sprayed into the bearing by means of high pressure eruption; the orientation of the nozzle should be placed between the inner ring and the middle of the holder.
The bearing is a fixed part of the machine; it is the main body of the machine; its effect is basically used to adhere to the middle orientation of the shaft; and the mechanism that controls the movement. SKF bearings have an insignificant effect in any machine; if not The bearing; the machine can't work.
Many users have reflected; when using imported bearings; bearing heat is the most common; this problem will also affect the life and function of SKF bearings. So; how is this problem? Below; is the common sense that we have summarized for us.
1. The oil level is too low; the smoothing agent is lost from the oil seal,
2. The grease in the bearing box is completely filled or the oil level is too high. This will cause smooth over-fire mixing; high temperature or oil leakage occurs.
3. The touch type (conflict) oil seal is too dry or the spring is too tight.
4. The inner hole of the bearing box is not round, the bearing box is distorted and deformed, the bearing surface is not flat, and the inner diameter of the box hole is over.
5. The touch type (conflict) oil seal is too dry or the spring is too tight.

High Speed Beam Drilling Machines
1. The cnc machines is mainly composed of main body, CNC slipway, drilling spindle box, tool changer, clamping device, measuring device, electric system, hydraulic system, cooling system, chip box, etc..
2. Three slipways are all controlled by servo motor, guided by precision linear roller guide and driven by AC servo motor and ball screw to ensure the positioning accuracy. The spindles are precision spindles with high rotary accuracy and high rigidity, and driven by servo motor, with broad scope of application, rotation speed can be stepless changed in a wide range to meet the needs of a variety of speeds.
3. The vertical drilling machine is equipped with three inline type tool changers, and every tool changer can load 4 tools. While drilling, the tools can be changed automatically to meet the needs of different drilling diameters. The machine is equipped with flange width detection and web height detection device, which can effectively compensate for the deformation of the workpiece to ensure the processing accuracy.
4.The main advantage of TD series high speed CNC drilling machine is it`s high speed drilling.It`s rotation speed can reach 3000rpm.
Due to it using the carbide drill bits, single hole processing efficiency increased to more than 5 times than the normal speed machine, the overall production efficiency more than 2 times than the normal machine. For example: 22 mm diameter, thickness 20 mm workpiece, CBD series drilling one hole need about 30 seconds, TD series can be controlled within 4 seconds.
