The most common application for spindle bearings
Bearings are utilized in many machine tools. Some examples where precision bearings are applied are drill presses or drilling machines, CNC controlled machine tools, industrial robots, machining centers, boring machines, lapping and honing machines, broaching machines, gear cutting, production milling, and gang drills. Machine turret lathes allow for a variety of turning, drilling, boring, reaming and thread cutting operations, in production machine tools some of the basic designs are multiple station machines, gang drills, production milling, and screw machines all needing high precision bearings.
How do I choose a machine tool spindle bearings?
When selecting machine tool spindle bearings you must consider vibration, heat generation, humidity, environmental contamination, and speed and loads.
Several factors go into the bearing selection process for machine tool spindles:
- First, you must consider the space requirements and see if there are other mounting limitations.
- Second, you must calculate what type of loads and speeds are involved. When designing the bearing for each spindle application it must be determined what precision and stiffness is needed. As with all bearing applications one must consider the operating temperature, vibration and contamination issues.
- Finally, you must determine lubrication and if seals are required are desired.
Selecting the bearing is critical in optimizing spindle unit performance and reliability.
Spindle units are critical in the primary functioning of machining tool operations. Spindle designs include belt-driven and motor-integrated spindles. Spindle bearings are used in many machines including high speed milling and high capacity turning operations.
Selecting super high precision bearings is essential for successful machine tool spindle operations.
