Machining (CNC)

In addition to speed, the new robots handle an increased number of workpieces/tools, are more compact and consume less energy. They also support the latest WALTER HELITRONIC Tool Studio and Robot Manager software that allows users to load multiple trays with various workpiece diameters for lights out unattended 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.

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. 

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.

The HCN-6800 NEO received numerous upgrades that take the previous generation’s performance to a new level of efficiency and ease-of-use. The standard spindle, table, and magazine have all received significant improvements, including an upgraded, new standard 43-tool drum-type magazine that reduces tool exchange times. A redesigned ATC door is now servo-driven and faster; the new design will now also accommodate a longer tool. Likewise, for ease of maintenance, the machine incorporates hydraulic/motorized pallet changer mechanisms and an easier-to-access maintenance panel.

The machines within the i-H Series sport new, ergonomic enclosures with compact footprints that require less floor space. In addition, Mazak equipped the machines with faster and more powerful turning spindles, space-saving milling spindles and a new parallel-type lower turret with optional live tooling capabilities. The company also expanded tool capacities for lower turrets and for tool storage magazines along with offering a wider range of chuck size options.

Among the primary enhancements on the VARIAXIS i-800 NEO is the MAZATROL SmoothAi CNC. It features such functions as SMOOTH Machining Configuration (SMC) for process optimization with real-time operator control of a wide range of cutting parameters and Ai Thermal Shield for stable machining accuracy through smart compensation for heat displacement. Also with the launch of the MAZATROL SmoothAi, Mazak introduced its SMOOTH Project Manager Gateway software as an available option.

Mitsubishi and Absolute jointly designed the plug-and-play cell. It consists of a Mitsubishi industrial robot, a wheeled stainless steel base, a clear polycarbonate cell enclosure featuring a safety door with an interlock switch, and a side table extension. The cell accommodates Mitsubishi 6-axis RV-series robots ranging in load capacity from 7 kg to 20 kg and reach up to 1,388mm. Integrating the robot cell with a CNC machine is a one-step process using a single Ethernet cable, Mitsubishi’s Direct Robot Control function and the Mitsubishi M8 series control. The LoadMate Plus can also interface with other control types via remote I/O connectivity.
