FAQ: What is the best way to reduce vibration in machining?
Vibration is the killer of cutting tools and tool life! Of course, the most straight forward way to negate vibration is to get the cutting data correct in the first place and optimise the radial and axial depths of cut to limit its effects.
Other than the cutting parameters two of the main causes and contributors to vibration are a poor spindle connection (between the spindle taper and tool shank) and tool run-out. All NIKKEN tool holders are designed and manufactured to reduce the risk of either of these situations causing an issue.
Firstly we provide our users with the absolute confidence of a guaranteed 80-85% taper contact to negate movement between the spindle and tool taper and eliminate ‘fretting corrosion’. Secondly all NIKKEN chucking solutions provide, as standard, better than 5 microns run-out at the cutting edge! Poor tool run-out can be one of the key contributors to vibration and if run-out can be controlled then conversely vibration is reduced.
The added advantage for all NIKKEN users is the benefit to tool life that reproducible and reliable run-out can provide! As an example should 21 microns of tool run-out be reduced to 3 microns, also easily achievable with NIKKEN’s optional precision collets, then tool life is increased by up to five times!
