Hydraulically Driven High-Speed Spindle for General Machining

Spindles are the most critical elements of high-speed milling machines. The keys to successful design of high-speed spindles are strength, rigidity, and balance. The hydraulically driven spindle includes a hydraulically driven gearmotor. The rotation of the motor is transmitted to the main shaft of the spindle.

Toolholder and tool balance | Cutting Tool Engineering

Where G is the balance grade, 9,549 is a constant that makes the units consistent, W is the mass of the rotating object in kg and rpm is the spindle speed. The balance grade depends on the application. For example, G6.3 is typically specified for general-purpose machines, G2.5 for high-speed machines and G1.0 for precision machines.

To Balance, Or Not To Balance? Toolholders, That Is

Machine tool builders rely on an outdated number, too, often basing spindle warranty coverage on using balanced tools at very specific close tolerances. While it's true that poorly balanced tools run at high speeds wear a spindle faster, decently balanced tools performing common operations won't wear spindles or tools drastically and deliver the results …

Fundamentals of tool balancing - Haimer

Fundamentals of balancing. With rotating bodies, imbalance is an omnipresent phenomenon. A typical example are rotating tools on machine tools. Because unbalance creates a centrifugal force, it increases linearly with the unbalance and squares with the number of rounds. The faster the rotor rotates, the more noticeable the unbalance.

Why You May Need a Balancing Machine - American Machinist

That is the reason that manufacturers of milling machines and spindles specify the use of balanced tools. Often, if unbalanced tools are used, there will be no warranty on the machine spindle. The direction of the centrifugal force that results from unbalance changes as it rotates with the spindle causing vibrations, and vibrations shorten the life of the cutting tools.

Balancing Considerations for High-Speed Machining ...

This latter fact is why many machining center manufacturers recommend balanced tooling and in some cases actually void the spindle warranty if balanced toolholders are not used above a certain speed. The threshold that defines high-speed machining for the purposes of balancing historically has been 8,000 to 10,000 rpm.
