By examining the natural frequencies of the spindle drive, it was checked whether an unacceptable resonance case caused the excessive vibrations and chatter marks. After excitation by hammer impact, the linear guide was found to have a natural frequency at 104 Hz. Thus, the linear guide is excited to strong vibrations by the material cut of the individual cutting edges of the milling cutter, which acted on the material surface as chatter marks. Due to a design change in the linear guide (stiffening), its natural frequency was shifted accordingly. The result was a clean milling pattern.

The frequency analysis carried out in parallel also clearly shows the rotational speed (21.7 Hz) and the material contact at 5 times the rotational speed (108 Hz).

Measurement of the vibrations occurring at the spindle head to determine the main frequency of the chatter vibrations. A subsequent natural frequency analysis at the machining centre determines the resonant component.

SFM to RPM

On a CNC travelling column milling machine, chatter marks occurred at a spindle speed of 1300 rpm (21.7 Hz). The measurement was carried out directly on the main spindle using an accelerometer which was coupled to the main spindle by a magnet. In order to get an overview of the occurring vibrations, the time signal of the vibration velocity was displayed in real time using the measuring kit for machine protection/machine diagnosis. The picture shows in high resolution the individual revolutions of the milling cutter and at the same time the material contact of the 5 cutting plates of the milling cutter. At a milling speed of 1300 rpm, the time interval between the material cuts is 9.3 ms or 108 Hz.

The Magnum Super Premium drills will substantially outperform cobalt drills in work hardening stainless steel applications. This performance advantage is the result of construction differences between the two types of drills. Cobalt drills, manufactured to Type J NAS907 specs, has a very thick web. This web is necessary to limit breakage of the brittle cobalt steel. Magnum Super Premium drills are made of special Hi-moly tool steel, which is much tougher than cobalt steel. The web on a Magnum Super Premium drill can be thinned considerably due to the toughness of the steel.A Magnum Super Premium drill with its thin web will penetrate the work hardening stainless fast enough to continually cut beneath the chip which is hardening from deformation. This means the drill is cutting softer steel. The cobalt drill, with its thick web, cannot be fed at a fast enough rate to cut beneath the area which is hardening. As a result the cobalt drill is continually drilling into hardened steel.
