![]() ![]() “The products were selected to offer the most popular Rego-Fix products for multitasking machines with a Capto interface,” said Peter Tester, president and CEO of Rego-Fix AG, Tenniken, Switzerland.Ī Coromant Capto toolholder with the PowRgrip collet from Rego-Fix. Rego-Fix offers monoblock Coromant Capto toolholders with ER and powRgrip collet systems. ![]() “Because it has a polygon shape, a Capto toolholder couldn’t turn inside a spindle, so the whole transferrable torque of the spindle is on the entire taper of the Capto holder.” Weber, president of Rego-Fix Tool Corp., Indianapolis. “A CAT or BT holder has keyways at the flange that transmits torque,” said Andreas S. The polygon also provides torque transmission from the machine tool spindle to the cutting tool without the need for keyways. The polygon taper ensures automatic radial centering and even pressure around the coupling, according to Sandvik Coromant, enabling repeatability within 2μm. ![]() “I found the three-sided polygon provided superior stability.” “Why does a modular system have to be circular?” Andersson asked. The Coromant Capto’s three-corner polygon shape distinguishes it from other toolholders. We drove this certification to make sure no one could change the design, and that’s what ISO certification achieves.” “We wanted to ensure that if anyone makes it, and anyone is more than welcome to make it, all the tolerances are exactly the same as the original. “When the patent ran out, we didn’t want people to make a lower-quality version so that it started to create problems for those who had Coromant Capto,” said Chris Mills, national portfolio manager for Sandvik Coromant, Fair Lawn, N.J. Sandvik Coromant’s Coromant Capto machine adapted clamping units (MACU) for lathes are suitable for turning and milling applications. ISO certification means no manufacturer can sell a Coromant Capto holder that doesn’t conform to the standard’s specifications. ![]() Since then, Coromant Capto has made industry inroads via sales by Sandvik Coromant and its various licensees and was adopted in 2008 as an ISO standard (26623) for toolholding systems when the company’s patent expired and the need to license it ceased. Sandvik Coromant completed the first prototype in 1989 and unveiled the full version at IMTS 1990 in Chicago. Ken Andersson, who has since retired from the toolmaker and now builds boats, invented Coromant Capto. For the Coromant Capto toolholding system developed by Sandvik Coromant Co., modularity, universality and repeatability define it. Those are definitions of the Latin word capto. Ever wonder why you can't run some jobs on certain machines? It could be the drawbar force is low.A look at the Coromant Capto modular toolholding system.This check takes less then 1 minute to perform if you have the right tool you can save the service call. Most service companies may not have this tool in there van when they come, which means they are looking for other problems.Possible injury of employee if/when tool is thrown.Shipping bad parts to your customer (Priceless!).Why is a Clamprite Drawbar Dynamometer a must have tool for every machine shop? If you know you are only going to use the head within a specific pressure it is better to select the lower gage to have a finer visual resolution. Pressure gauge size when ordering: Though you can read smaller spindles with a higher pressure gage. (Complete Kit including Gage Head and toolbox) Our units are almost solid steel except for the gauge itself. Order additional clamprite adapters below if you already have a drawbar Dynomometer.ĭigital dynamometers cost three times as much and are more delicate and prone to problems when they are dropped or used during machine repair. Select your clamprite Dynamometer kit by spindle type and maximum pressure. The clamprite universal head adapts to all the CAPTO sizes, including CAPTO 03, 04, 05, 06, 08. Collect pull studs from each of your machines and store them in the clamprite box for easy access. Our Clamprite gage kits are furnish ed in a metal tool box which include the gage head, a spindle adapter, and coupling that accepts the pull studs. A spindle clamp force gage is also commonly known as a spindle drawbar dynomometer. Having a clamp force dynomometer can save huge costs including spindles, downtime, paid service and loss of tool life. CAPTO C3, C4, C5, C6, C8 Spindles require checking the drawbar frequently not to mention takes less then a minute. Our Clamprite CAPTO Drawbar Gage Kits provide an easy, accurate, and economical method of checking the drawbar force of a spindle. ![]()
