Eliminate vibration chatter!

Holder with high damping capacity matched to the vibration characteristics resolves processing chatter!

High damping capacity by dedicated design to match the equipment/tools used

Stable quality due to improved machining accuracy

Reduced investment due to highly efficient processing

Amazing facts!

── Introducing ideas and technologies ──

Vibration analysis of equipment/tools in use is performed on-site.
For details, please refer to “Vibration Analysis and Diagnosis service”.
Hammering investigation is conducted in advance to design the optimum damper to maximize the damping effect.
This solves machining chatter, improves machining efficiency, and enhances quality.

This is the point!

Optimal damper design for each tool

Excellent!

Hammering test (on site) – Investigation the vibration characteristics of the equipment/tools used with hammering.

Design – Design of the optimal damper based on investigation results.

Chatter suppression effect

Good!

Comparison of dynamic stiffness near the cutting edge​

Compliance (springiness): reduced vibration at all frequencies.

Higher efficiency with damper

Good!

Work material

JIS S45C / EU EN C45 (1.0503)

Tool diameter

ø115 mm

Cutting conditions

Spindle speed: n = 500min-1
Feed: f = 0.10~0.25 mm/edge

Number of edges

1-6 cutting edges

Machining allowance

ø0.4 mm

Vibrations are caused by increased feed and high number of teeth and therefore, needs dampening.
A boring holder equipped with damper enables more efficient processing than before.

Development / product concept

“Current status and challenges”

  • With the diversification and generalization of workpiece types, there is an increasing need for machining of difficult-to-machine materials and long tools with high efficiency.
  • One of the problems faced by production sites is the occurrence of regenerative chatter due to machining vibration, resulting in deteriorated machining accuracy, cutting edge defects and unachieved cycle times.

“Development points”

  • The “Damper Holder” demonstrates a high vibration suppression effect by designing the optimum damper for the equipment and tools actually used, while also improving the machining accuracy and efficiency.
    It is also expected to extend the life of cutting edges due to chattering.
