New MULTI-WEDGE clamp holders for ISO turning
|
|
|
|
ISCAR is introducing a new modular turning system with top wedge clamping. On each external holder, three different inserts can be used. On the boring bar, two types of inserts can be used. Each type of insert is clamped into a different top wedge clamp. The use of the single MULTI-WEDGE holder body or boring bar with various inserts provides flexibility in application and setup and is more economical and simple to use.
Trigon (W), Rhombic (C) and Square (S), inserts are pushed against the central pin from their rear side by the wedge and clamped from the top in order to secure their position strongly and accurately.
Accuracy and Repeatability:
The new design with its original clamping device provides excellent accuracy and repeatability due to carefully balanced clamping forces and high accuracy of all parts. Edge location repeatability of the cutting edge with a single insert was measured to be as high as
± 0.01 mm.
Precise insert orientation is especially important when using wiper type inserts (WG and WF chipbreakers). The strong and safe clamping combined with high repeatability guarantees the essential angle of the wiper edge in relation to the machined workpiece and thereby ensures high surface quality.
Range of Toolholders and Boring Bars:
The designation of the new holders is MULNR/L and for the boring bars, S-MULNR/L with the suffix MW. The letter U stands for the universal or multi-shaped type of the tool. MW distinguishes the new multi-wedge system from the previous W type.
The interchangeable pockets are available for insert sizes of 12 for square (S) and rhombic (C) inserts and 08 for the trigonal insert.
