Spindle shafts are essential components in lathes, milling machines, and other machine tools. Spindle shafts can be with or without a rotor. Spindle shafts are made of high-quality materials to ensure maximum precision and reliability in mechanical processing. The choice of spindle shaft type depends on the specifications of the machine tool and the type of machining to be performed.
Spindel shafts with a rotor
Mandrel shafts with a rotor are designed to rotate at high speeds and require accurate balancing to avoid vibrations and damage to the machine. Balancing of the mandrel shaft is carried out by adding or removing weight to minimize vibrations.
Spindel shafts without a rotor
Spindle shafts without a rotor are designed for low-speed applications and do not require balancing.
Fixed spindle shafts are commonly called “rigid spindle shafts” or “fixed spindle mandrels” and are used in machine tools where the tool or drill bit is manually replaced without the need to change the mandrel. Instead of having a separate mandrel, the rigid spindle shaft has an external thread on its outside onto which the tool or drill bit is screwed directly. This way, the tool or drill bit is held firmly on the spindle shaft without the need for a separate mandrel.
Rigid spindle shafts are more economical than those with a mandrel and are often used in simpler machine tools or in less complex machining, where maximum precision is not required. However, being without a mandrel, they can be less convenient to use and require more time to replace tools or drill bits.
In general, the choice between spindle shafts with or without a mandrel depends on the specific needs of the machining process and the machine tool used.
