Hydraulic Power System Cuts Energy Use, Maintenance on Machine Tools
MJC Engineering, known for its CNC metal-spinning, rotary-forge and flow- forming machines, showcased its new hydraulic power system, Green Hydraulic Power. This system reportedly provides higher machine yield, reduces noise emis- sions by 20 dBA, generates less heat, pro- duces a shorter cycle time on various machine types and involves less oil vol- ume, all resulting in a system that saves as much as 70 percent in energy costs as
compared to previous systems.
Green Hydraulic Power is offered as a
value-add on MJC’s Spectra Line of hydraulic power units provided on MJC machine builds and utilizes the Siemens Sinamics variable-speed servo pump drive. “We saw that the servo pump could control pressure and flow, as they precise- ly convert electric energy into hydraulic power,” explains Carl Lorentzen, president. “In some applications, the use of control valves is partially or completely elimi- nated.” www.mjcengineering.com
Tool Changers for Press Transfer Rails
ATI Industrial Automation, Apex, NC, displayed its rail tool changers at FABTECH for rapid changeover of press transfer rails. The tool changers are engi- neered to withstand the high-speed, high-inertia loading environment that is typ- ical with this process while providing the flexibility to automatically change end- effectors or other peripheral tooling. All ATI tool changers feature the company’s patented Fail-Safe locking mechanism and No-Touch locking technology.

Unique Tube-Cutting Process Reduces Tool Wear
Sawing-technology specialist Kasto Maschinenbau GmbH & Co. debuted the KastoWin Tube A 5.0, specially
designed for machining tubular
material. With a saw feed rotated
through 180 deg. and sawing per-
formed upward from the support
surface, the fully automatic
machine works efficiently to
reduce cutting-tool wear. It fea-
tures a cutting range of 500 mm
with a shortest possible cutting
length of 10 mm. Using a frequen-
cy-controlled drive, cutting speed
can be adjusted continuously
between 12 and 150 m/min. Car-
bide saw bands of the type
required for various tubular materials can be used without the need for any accessories.
The saw band clamps in position hydraulically and is cleaned using a replace- able, electrically driven chip-removal brush. The vice and saw feed are equipped with zero-play linear guides, and ball-screw spindle drives ensure controlled cutting and material-feed movements.
The SmartControl sawing-machine controller contains all material data and automatically sets all necessary parameters. www.kasto.com
