Answers to some questions you may have

What are the vibrations in machining? What is regenerative tool chatter?

All machine tools vibrate when the turning or milling insert engages the workpiece. The machining tool naturally vibrates at certain frequencies when cutting a workpiece. This causes surface marks to strike on the workpiece. In most cases, impact surface marks excite the tool holder structure with a frequency close to the natural frequency of the structure. This is where the structure is weakest. Regenerative tool noise refers to the situation where the machining process is chaotic in terms of vibration and the vibration increases over time as the machining process continues.

Why is vibration something I should be worried about?

Vibrations occur in all types of metalworking processes. Cutting tool performance will be affected by vibrations. Since machining vibration is something you cannot eliminate, you need to find ways to reduce it. Reducing vibrations means better tool performance, higher production speed, significant savings and better surface quality.

What is vibration damping technology?

A method for absorbing vibrations that occur between a tool and a workpiece. (In the metal cutting industry, known as tool chatter). Vibration damping normally converts vibration energy into thermal energy/heat. The mass damper will first transfer the vibration energy from the cutting tool to the heavy mass and then convert the vibration energy into thermal energy. Vibration dampening technology will reduce the risk of production stoppage and improve surface quality on machined parts.

What is a self-adjusting mass damper tool holder?

A self-adjusting mass damper (STMD™) tool holder is a tool in which the hardness support of the mass automatically adjusts to vibration frequencies in metal cutting operations. MAQ was the first company to develop a self-adjusting mass damper tool holder. When vibration occurs, the self-adjusting mass damper means will assist in transferring the vibration energy from the cutting tool to the mass damper and then damping/converting the vibration energy on the mass damper into heat/thermal energy.

What is the difference between a tuned mass damper tool and a self-adjusting mass damper tool?

Many suppliers offer tuned mass dampers tool holders. Either these solutions are tuned to a preset frequency or you have to fine-tune the tool holder during the machining process. MAQ's STMD™ tool holder is the only frequency-adjusting solution in a machining operation.

How do I install a damped machining tool holder on my machine?

Our vibration dampened tool holders come in standard sizes with or without a standard joint design. To install one of our flat cylindrical shaped, vibration-damped turning tool holders, you must use a standard adapter to mount the tool via the reduction sleeve, all-round clamping, hydraulic clamping, or shrink-fit clamping. When installing a damped turning tool holder with a set mass damper inside, avoid using screws for direct mounting to attach it to the surface of the tool holder. Because direct contact can damage the damping system. Direct screw mounting also has low bending stiffness/stiffness.

How can I keep the vibration-damped toolholder in top working condition?

We recommend using cooling media (lubricant, emulsions, or compressed air) when using MAQ’s vibration damped tool holders. To maximize the effectiveness of your tool holder, it should never operate at a temperature above 100°C (212°F). Overheating reduces effectiveness and accelerates the aging of the tool holder’s internal components.Answers to some questions you may have
