Machining

The DDHM system is aimed primarily at customers in the tool and die-making industries. The focus is on machining carbide punches and dies efficiently. The tool system also offers significant advantages in other areas such as the medical and aerospace sectors, the automotive industry, and punching, forging and forming technology. The diamond tools enable shorter throughput times, high surface quality, lower overall costs, greater flexibility within the production process and longer tool life. The drills can be used for producing holes in solid material to a maximum depth of ten times the diameter. The CVD-D tipped drills have a two-edged design and are available in diameters ranging from 2 mm (0.079") to 10 mm (0.394"). All versions boast internal channels for cooling with air.

TwistSFeed reduces costs by improving tool life as well as achieving higher productivity due to multiple flutes along with new IN2205 coating designed for steel and cast iron applications. The clamping mechanism allows for the simple replacement of drill tips as well as accommodating multiple tip diameters per drill body facilitating economical stock management for end users.

The CoroTap T200 and T300 are optimized for ISO P1 and P2 steel workpiece materials, making them suitable for machining components in the automotive and general engineering industries. This includes crank shafts, steering knuckles, and general engineering components such as housings and flanges. Both tools are suitable for mass production.

The machine is built on a Romi-made monoblock base and has a net weight of 20,300 lbs. It features linear roller guides for the X, Y, and Z axes and direct rotary encoders for the B and C axes. This combination reduces vibration and produces high rigidity and precision. The DCM 620-5X Hybrid also features a 40 big-plus taper direct-drive spindle capable of 15-15,000 rpm, a 24 hp motor, a 24" x 20" x 18.1" table (X, Y, Z), and a 30-tool automatic tool changer. It is equipped with a Siemens Sinumerik 840D sl CNC that features a 19" touch screen.n

Both grinding spindles are "synchronous direct‐drive spindles" with 19 hp peak each. The most important feature of a synchro­nous motor is that it provides constant speed during its operation and that the torque curve is highly efficient, as per above graph. The rotational force is not reduced with higher RPM's. Synchronous motors always run at a speed equal to their syn­chronous speed, as opposed to asynchronous motors (induction motors) which always have a lag and are therefore less effi­cient.

Cutting diameter sizes range from 1/8" to 1/2". Included angle options are 90° or 120°. The two-flute design is optimal when chip evacuation and increased chip per tooth are the priority. For harder materials, the fortified strength of the four-flute design performs best and allows for increased feed rates in hard materials. Items are stocked uncoated or AlTiN coated. AlTiN coating is highly recommended for longevity and high-speed applications.n

Effective April 1, 2021 the names of each of these models will also change. B, F or V will be the first letter of each product name. ChipBLASTER options including Chillers, Mist Collectors, Oil Removal Systems, Cyclonic Filtration and Sludge Tank remain unchanged. Additionally, an inexpensive wash wand that uses coolant to wash down the inside of a machine tool, is available for the F- and V- Series systems.

High-performance Step-Tec spindles are built for all milling operations from roughing to fine surface finishing. With advanced hybrid ball bearings and thermally robust hybrid cylindrical roller bearings, the spindles enable milling with extra-long tools while delivering aggressive material removal rates at high feed rates. GF Machining Solutions will also offer, as optional, the Step-Tec spindle in 24,000 and 36,000-rpm versions.

The updated automation package accommodates denser pallet arrays for improved lot sizes and runtime, while delivering smoother robot operation and better repeatability. Additionally, the system can now adapt to multiple part profiles to be produced within a single run. An optional laser marking system has also been integrated for automated tool marking, in addition to many other new features.
