We Simplify Machining by Reducing Vibration

MAQ is a Swedish engineering company headquartered in Stockholm. The company works closely with European manufacturing partners and global distributors, but the core R&D is carried out in Sweden. This ensures consistent quality, reliable performance, and a strong focus on technical problem-solving rooted in Scandinavian engineering.

STMD™ (Self-Tuning Mass Damper) is MAQ’s patented vibration-damping technology that automatically adjusts to changing vibration frequencies during machining. By adapting in real time, it absorbs and dissipates harmful energy that causes chatter, poor surface finish, and premature tool wear. Unlike traditional tuned mass dampers, it requires no manual calibration or setup. The self-adjusting design offers a plug-and-play solution that improves machining stability, enhances tool life, and enables smoother, more accurate results across various cutting operations and materials — helping manufacturers simplify machining with higher process reliability.

MAQ’s vibration-damped tools equipped with STMD™ technology deliver stable performance even at long overhangs — typically between 5×D and 15×D, depending on diameter, material, and setup. The technology automatically adapts to each tool’s vibration frequency, maintaining consistent stability in deep-hole and long-reach machining. This eliminates the need for manual tuning or recalibration while allowing users to operate at higher speeds and feeds. Whether used in turning, boring, or milling, STMD™ ensures precise cutting performance and surface quality even when solid tools would struggle with excessive vibration and instability.

MAQ’s STMD™ technology minimizes vibration and chatter, resulting in smoother surface finishes, longer tool life, and improved dimensional accuracy. The self-tuning mechanism ensures stability under varying cutting conditions, allowing higher feed rates and shorter cycle times without compromising quality. By eliminating manual adjustments and reducing vibration amplitude, users experience more predictable processes, reduced tool wear, and fewer finishing operations. The overall effect is better productivity, consistent part quality, and reliable performance – making STMD™ a practical solution for manufacturers aiming to enhance machining precision and efficiency across multiple applications.

Vibration-damped tools provide the greatest benefits when machining materials that are prone to work hardening or create high cutting forces. Stainless steels (304, 316, duplex grades) see significant improvements because they harden rapidly when vibrations cause inconsistent chip formation. Titanium alloys and heat-resistant superalloys (Inconel, Hastelloy) benefit substantially due to their poor thermal conductivity and tendency to create chatter. Hardened tool steels above 45 HRC also show dramatic improvements in stability. Even standard materials like carbon steel and cast iron can benefit from damping when working with long overhangs or thin-walled components where rigidity is limited.

Yes. STMD™ vibration-damped tool holders enable higher cutting speeds and feed rates while maintaining surface quality and dimensional accuracy. By automatically controlling vibration, the technology allows more aggressive machining parameters without chatter or instability. In many operations, users report productivity increases of up to 30–50%, shorter cycle times, and fewer tool changes. This results in smoother processes, reduced downtime, and lower maintenance needs. The self-tuning system’s plug-and-play design ensures consistent performance and faster machining – a direct path to improved efficiency and lower total production costs.

You likely need vibration damping if you experience any of the following:
– Visible chatter marks or poor surface finish
– Tool wear or breakage before expected lifespan
– Noise or vibration during cutting
– Overhangs above a 4:1 length-to-diameter ratio
– Trouble holding tight tolerances in deep or narrow bores

MAQ’s STMD™ tools are designed to handle these challenges automatically, maintaining precision and stability where solid bars lose rigidity. By reducing vibration at the source, STMD™ enables smoother operation, improved tolerances, and better overall machining efficiency.

MAQ’s vibration-damped tools with STMD™ technology are used wherever machining precision and stability are essential. Key industries include:
– aerospace, where lightweight structures require vibration-free cutting
– automotive, for high-volume precision production
– oil and gas, where long-reach machining is common
– medical manufacturing, for small, complex parts.

General machining also benefits when working with reduced rigidity or extended overhangs. Across all sectors, STMD™ improves tool life, productivity, and surface quality by automatically adapting to vibration frequencies – delivering consistent performance in materials from steel and titanium to advanced alloys.
