Electric Machines Come With Built-in Robot

There’s no installation time or effort needed with the new Fanuc SR Mate 100iB all-servo robot because it comes already installed and ready to run on all-electric injection machines from the same supplier.

There’s no installation time or effort needed with the new Fanuc SR Mate 100iB all-servo robot because it comes already installed and ready to run on all-electric injection machines from the same supplier. The new robot option is available only on new Fanuc Roboshot SiB machines (no retrofits), sold here by Cincinnati Milacron, Batavia, Ohio. The robots are available on 55- and 110-ton models. Later this year, Fanuc and Milacron will introduce the SR Mate 200iB for 165- and 330-tonners. Meanwhile, Milacron also introduced two new Roboshot machines. The robot comes in a dual-arm, five-axis model with a separate sprue picker or a single-arm, three-axis version without picker. Concurrent motions of the two segments of the telescoping arm contribute to extraction time of just 0.5 sec. Total height on a Roboshot 110 is just 97.25 in. The robot comes with standard teach pendant and can be mounted on either front or back side of the machine. The newest Roboshot SiB size is a 275-tonner, joining a line that runs from 18 to 375 U.S. tons. These machines have new servo technology, 10 times faster control updates, a lower-inertia injection unit, and enhanced artificial intelligence functions. The Roboshot 275 provides shot size up to 114 g, maximum injection rate of 330 mm/sec (16.2 cu in./sec), and injection pressure up to 40,000 psi. Tiebar spacing is 28 in. square. Also new is a version of the 165-ton Roboshot SiB designed for medical and other tight-tolerance applications that use relatively large, multi-cavity molds to produce very small parts. Such applications need high injection speed and pressure but low shot size. Thus the Roboshot 165 “micro” carries an 18-mm screw, more typically found on a 33-ton machine, capable of injecting as little as 18 g (0.63 oz) at 330 mm/sec (5.1 cu in./sec) and 35,550 psi.
