Toolholders similar ISO 7388-2
(ex. JIS B 6339 MAS 403 BT)
with Taper-Face [DUAL Contact]
Pre-balanced G 6,3 15.000 min-1
G 2,5 Fine balancing at extra charge
With internal coolant through the collar - form AD/B
Material:
Alloyed case-hardened steel, tensile core strength of min. 800 N/mm².
Case hardened HRC 60 ± 2 (HV 700 ± 50), hardening depth 0.8 mm ± 0.2 mm
Form AD/B:
Delivery in form AD, type B closed with releasable headless screws.
Accuracy:
Quality of taper < AT 3 according to DIN 7187 and DIN 2080.
Deviating designations:
BTKV - Kegel- und Flanschflächenkontakt
„Dual Contact"-Face tooling used on Taper-Face spindles achieve additional contact between spindle s face and holder s flange (vs. face/flange clearance with conventional steep taper fittings).
Advantages:
- Higher pulling forces (compared to classic spindles) achieve flange contact with pressure, complementary to the taper fitting.
- Higher rigidity particularly profitable to long tooling and machining in difficult materials.
- Higher run-out precision and axial (length) repeatability.
Taper-Face tooling can be used on conventional steep taper spindles but losing the face contact advantages.
