Tool holding has a dramatic influence on machining in being the vital link it is in the chain of factors from machine to cutting edge. The interface between spindle and tooling and adaptors so directly affects capability in that it can directly limit or ensure competitive levels of cutting data, security and the results.
Coromant Capto: Tool-Holding Stability
Coromant Capto is the most stable tool-holding system available and is now an ISO-standard. It is a modular, quick-change system suitable for rotating and stationary tools, and as such can be used throughout an entire machine shop with different machinery. As a modular interface, it combines cutting tools, adaptors, extensions and basic holders to great flexibility.
The tapered polygon coupling is unique in transmitting the levels of torque and providing the highest great stability and accuracy. Different clamping methods give the system the versatility to suit various machine types and it has been provided with internal coolant facilities directed to the cutting edge, with high pressure coolant options. There are also extensions and reductions to provide set-up combinations with other C-sizes.
Optimization for all Sizes
A larger coupling size C1- is now available as standard for heavier machining. The Coromant Capto system is thus available for a complete range of sizes which now also includes the larger end of the program to extend optimization. The C10 size improves performance in larger machines by allowing higher feeds and depths of cut. Coromant Capto C10 has a flange diameter of 100 mm which means a coupling capable of the heavier loads in many milling applications and very high stability in turning. The Coromant Capto system provides very high bending stiffness for demanding operations and high accuracy at heavy loads. The new C10 standard ensures that tool holding is not the weakest link in the chain from machine to cutting edge at the heavier end of machining.
