The
automatic tool changer with ring-shaped tool crib is an essential component
for numerically controlled machine tools. It is generally installed on
vertical machining centers, but it can also be used on horizontal machines.
It comes in the following versions:
CTA 50
fits cones of the following types: ISO 50, ISO 45, BT 50, HSK 63, HSK 80 and
HSK 100 for tools with a maximum weight of 20 kg.
CTA 40
fits cones of the following types: ISO 30, ISO 40, BT 40, HSK 50, HSK 50,
HSK 63 for tools with a maximum weight of 10 kg. This type is still a
prototype and will be available in 2003.
Tool
cribs are manufactured in all dimensions as follows: for 30, 40 , 50 and 60
tools in the standard versions; however, given its modularity, tool cribs
can also be made available upon request for a different number of tools.
The CTA 50, just like the CTM 50, is light and
can be easily installed on machines with turn-able standards and quick
traverse.
The CTA-type tool changer consists of a CUT-type cam exchanger and a
patented ring-shaped tool crib. This tool crib does not use a chain, like
most tool cribs do, but uses a series of self-driving steel carriages that
carry the tool-holding bushes and can be easily disassembled and replaced.
The support is made of extruded aluminum therefore, the whole mechanical
unit is extremely light.
The operation is carried out by self-braking asynchronous three-phase
motors, just like in the CTM-type.
The standard operating mode is random. It is also possible to create a
system for a "fixed place" operation. However, this will slow the tool
exchange operation.

CTNE
The
CTNE 50 type shuttle tool changer are particularly useful for numerically
controlled machine tools with turn-able and fixed standards.
This device does not block the range, except for the changing of the tool,
because during the operation periods it is on the side of the machine
standard.
CTNE 50 fits cones of the following types: ISO
45, ISO 50, BT 50, HSK 63, HSK 80, HSK 100 and is completed by a ring-shaped
tool crib for 30, 40, 50, 60 or 70 tools.
This type can carry out the tool exchange
thanks to a vertical and horizontal spindle ("O+V" version). The operating
mode can be both "fixed place" and "random" according to needs. It consists
of a shuttle that slides on a prismatic guide. This guide is generally fixed
to the standard of the machine, that holds the tool changer. In the "O+V"
version, the tool changer unit is turned over by 90°.
The tool crib is ring-shaped in the CTNA version (see the description of the
CTA-type), while it is wheel-shaped in the CTNR version (see the description
of the CTM-type).
It is necessary to remark that shuttle tool changers, unlike others, are not
operated hydraulically but through electromechanical and pneumatic
operations. Using such operations entails a series of advantages, such as:
