Technical Presentation


Coromant Capto

Coromant Capto is the only tooling system
that is equally effective for Turning, Milling
and Drilling


What is Coromant Capto?
Turning

Quick change tooling system for fast tool changing and
insert indexing

3000 style clamping unit used as a modular solution

Cutting units can be pre-measured offline

Can eliminate measuring cuts


Quick Change Tooling
Why should we use it?









Machine requires frequent setup changes.
Measuring cuts are necessary to get on size.
Machining is performed with high cutting data
and relatively short tool life.
Machining often involves difficult-to-machine
materials.
One operator services more than one machine.


What is Coromant Capto?
Rotating

Modular tooling system for changing tool lengths

Front clamping for fast tool changing

Available in all Coromant tool holding solutions

First choice for boring program


Modular Tooling
Why should we use it?








Tooling is used on a variety of machines with
different taper sizes
Special tooling can be built from standard
components
Production requirements change
Inventory reduction


What is Coromant Capto?

Turning
Clamping units that bolt to
the turret or cross slide


What is Coromant Capto?

Turning
Clamping units built
directly into the turret


What is Coromant Capto?

Turning/Milling

Spindle interface for
Turn-Mill machines


What is Coromant Capto?
Rotating
Basic holders that fit
into the spindle

Types of basic holders
Rear bolt clamping
Retention stud
must be removed

Clamping from the
rear of the flange

Center bolt offers
highest clamping forces


Types of basic holders
Front clamping
Quick tool change
without removing the
holder from the spindle

Must be used
with drawbolt

Clamping from the
front of the flange


Flange diameter
The flange diameter is the
size of the coupling.
C3 = 32 mm
C4 = 40 mm
C5 = 50 mm
C6 = 63 mm
C8 = 80 mm
