Effect of operating temperature on bearing life

In order to prevent the occurrence of impermissible scale changes due to the layout changes of the materials during the operation; it is necessary to pass special heat treatment for the bearing data.
According to different bearing types; the standard bearings are made of hardened and induction hardened steel; the highest operating temperature is between 120 and 200 degrees. The maximum operating temperature that can be reached is directly related to the heat treatment process. Contact. If the normal operating temperature of a certain use is higher than the claimed maximum temperature; the bearing with higher stability level should be selected. If the bearing demand is connected at high temperature, the dynamic load of the bearing can be adjusted.

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.
