Introducing the MAQ Rotational Fine Boring Tools

Unparalleled Precision and Efficiency with MAQ’s Rotational Fine Boring Tools – The Next Step in Advanced Machining Solutions

by Bernard Martin

MAQ AB has introduced its new Rotational Fine Boring Tools, engineered for fine boring with exceptional precision, surface finish, and ease of operation. In this article, we're going to explore the key features, benefits, and applications of this new technology.

What Is Rotational Fine Boring?
​Rotational fine boring is a precision machining process commonly performed on milling machines, where the tool rotates while the workpiece remains stationary. This method is ideal for achieving high-accuracy hole dimensions and surface finishes.

However, as the tool’s length-to-diameter ratio (L/D) exceeds 3, vibrations become a significant challenge, demanding tools equipped with advanced vibration-dampening technology.

Unlike conventional turning tools with straight shanks, MAQ’s Rotational Fine Boring Tools are specifically designed to pair seamlessly with milling tool backends, which vary in their L/D ratios and vibration frequencies.

​Thanks to MAQ’s STMD (Self-Tuning Mass Damper) technology, these tools adapt dynamically to a broader range of vibration frequencies, delivering unmatched precision, stability, and reliability, even in complex machining tasks.
​

Key Features of MAQ Rotational Fine Boring Tools

MAQ’s latest tools boast a range of advanced features that set them apart -

• Self-Balancing Mechanism – Integrated technology minimizes vibration and ensures exceptional stability, even at rotational speeds up to 20,000 RPM. This results in smoother, more reliable cutting and reduced tool wear.
• Fine Adjustability – Precision adjustments in micron increments (0.001 mm) enable tight tolerances as precise as IT7—or even IT6—making these tools ideal for high-accuracy operations.
• Compatibility – Designed for use with standard toolholders  like CAT, BT & HSK, these tools integrate seamlessly into existing CNC machine setups without additional investments.
• Length-to-Diameter (L/D) Ratios Up to 7xD – The tools are capable of handling operations with extended length-to-diameter ratios while maintaining superior vibration control.
• Exchangeable Cutter Heads – These tools offer the versatility of forward and back boring operations, adapting effortlessly to your machining requirements.
• Coolant-Through Design – Integrated coolant channels flush away chips, cool the workpiece, and extend the lifespan of cutting inserts, improving performance and reducing downtime.
• Surface Finish Excellence – Cutting-edge design and vibration control deliver exceptional surface quality, often eliminating the need for secondary finishing operations.

Benefits of Using MAQ Rotational Fine Boring Tools

The MAQ Rotational Fine Boring Tools offer unmatched benefits that make them essential for high-precision machining:

• Precision Performance -  Achieve consistent, micron-level tolerances for critical components such as engine blocks, hydraulic valves, and bearing housings.
• Enhanced Productivity -  High-speed operation (up to 20,000 RPM) and reduced setup times deliver faster cycle times and increased throughput.
• Superior Vibration Control -  The self-balancing mechanism minimizes vibration, improving tool life, machine wear, and performance stability.
• Cost Efficiency - By delivering superior surface finishes, these tools reduce or eliminate secondary finishing operations like polishing and grinding.
• Extended Tool Life - Optimized cutting geometry and balance reduce cutting edge wear, ensuring a longer lifespan and lowering overall production costs.
• Maximum Flexibility - With L/D ratios up to 7xD and exchangeable cutter heads, these tools are versatile enough to tackle the most complex boring operations.

HOW STMD™ MAKES ALL THE DIFFERENCE

Tuned mass damper tool holders aren’t new, but self-tuning mass damper tool holders is unheard of – until MAQ. Our vibration-damping milling tool holders with the STMD™ technology are easy to install and easy to use. It works at any setup you have in your production facility.
​
You can think of it as a smart milling tool holder that adjusts to machining conditions in real-time while enabling you to reduce the total cost of ownership (TCO). You will be able to shorten production time in several ways. One of them is because our milling tool holders make tuning unnecessary – it does it for you automatically!
