There was no problem of that in the '80s or earlier. They are precise but I don't really think it was a matter of being able to grind one. but Capto is for sure one of my favorites. The investment can be fairly heavy in the beginning but as you build up your "inventory", what you need down the road for other jobs don't carry the tooling cost anymore. It's like any new system you put into place. Just remember that the initial costs are up front (or "start up" as we say). Most people/places get real freaked out by the costs of such tooling. but what can't? By far though, the system is the most stable to take 'abuse'. Now the question, "will a capto break"? Of course. even to the amazement of Sandvik with cuts I'm able to take.
I still like using long "solid" holders (not talking about side locks here) but I'm not afraid to set up long capto tool either. Couple this connection with "devibe" bars from Teeness, the cabability of the Capto system is huge from light to HD cutting and all sorts of accuracy ranges to boot. It is a very strong connection type, very accurate and even can solve some harmonic issues (which most modular systems can just by nature of connections). CAPTO.Ĭapto is still licensed by Sandvik but there are plenty of licensed builders including: Walter and Seco (of course), Rego-Fix, BIG (Kaiser, Daishowa), Kennametal, Ingersoll, Nikken, Schunk. I'm sure a lot of you have seen videos I've posted over the years and one thing is evident. Other modular systems just don't compare. Using C8 and even C6 tools on a 50 taper machining centre, the 50 taper is the weakest link.Ĭapto has saved my ass numerous times and has very much been a standard for my tooling selection over more years than I can count. To think that that multi-piece bar, taking that cut, is connected to the turret with a coupling that is barely two inches long, is absolutely amazing to my mind. The boring bar is a C6 bar with a SL coupling head and a C6 extension in a C6 (cam operated draw bar) block mounted on the OD of the turret. It's drilled 225mm deep with a 100mm udrill, then bored out to 240mm for the same depth. I have one production job that I run pretty regularly from 16" 4145H bar. It's useful in a machining centre, by way of allowing you to build a tool tailored for the job at hand with excellent concentricity and rigidity.īut where it really shines is in a lathe, for the reasons that ewlsey gave above, but also for the sheer rigidity (have I used that word enough yet?) it provides. As someone who runs more capto tools than not, in all our machines, here's my take on it.Ĭapto's strengths are rigidity, accuracy, repeatability and torque transmission.
