CAMFIX MAXIN, VDI and Sleeve-Type Tool Blocks for WHISPERLINE Boring Bars
Highlights
ISCAR introduces standard CAMFIX, VDI and sleeve-type tool blocks for use with WHISPERLINE boring bars
CAMFIX for WHISPERLINE
Following the market demand growth for WHISPERLINE boring bars with CAMFIX clamping, ISCAR is now offering attractive clamping solutions based on existing standard items.
WHISPERLINE boring bars can be clamped on existing CAMFIX power chucks without affecting performance.
The combination of CAMFIX power chucks with the WHISPERLINE bars is ideal for stable machining in long overhang applications.
The standard guideline when clamping a WHISPERLINE bar in a split sleeve is to clamp 4XD of the shank length to obtain satisfactory results
Extremely high gripping force of the CAMFIX power chuck ensures good performance also with 2.5XD clamping
Due to hole depth limitations in some of the standard CAMFIX holders, the WHISPERLINE bar might have an overhang of over 10XD. In such cases, we firstly recommend trying to work as is with the existing overhang. In cases where performance is unsatisfactory, shorten the bar to be within the 10XD limit

Reduction Sleeves (bushings) for Tool Blocks and VDI Holders
The reduction sleeves (bushings) are made for tool blocks as well as for the VDI tools.
It is critical to clamp WHISPERLINE boring bars in split sleeves in order to ensure effective
chatter reduction.

Why WHISPERLINE boring bars should be fully clamped
The WHISPERLINE boring bars are built with an auxiliary mass damper immersed in
absorbent oil.
To make sure the boring bar works, it must be induced by vibrations, which means that vibrations
need to be transferred to the boring bar itself. This is possible only with very rigid clamping on the
machine side and the clamping device.
A single point screw provides partial clamping efficiency which cannot ensure that the
vibration energy is fully transferred to the boring bar.

The adjustment screw has an internal coolant hole
Use of DCONWS diameter tools provides best performance, as collets reduce the gripping force.

(2) Maximum diameter by using a reduction collet
(3) Max. diameter without a collet
