  Tech Update
 Servo Press Cuts Cycle Time, Electricity Usage
Industrial Innovations has debuted its Spra-Rite Ultra Lube system, a turnkey unit for applying highly viscous lubricants— to 800 cps—to stamping or drawing tooling as well as stock at predetermined press- stroke intervals.
Plasmet Czechowicz, a Polish metalformer specializing in steel and aluminum com- ponents for a variety of applications, performed a thorough analysis prior to deciding to purchase a new servo-mechanical press. Ultimately, the company chose a 630-ton- capacity model from Schuler (with U.S. headquarters in Canton, MI) to produce automotive stampings. Use of that press has shortened the part production cycle by 30 percent, according to Plasmet officials.
The pedestal design allows for simple transport from press to press, making it an ideal solution for smaller shops that process high-strength materials and require lube-system mobility.
The press brings other savings as well. For example, a third motor, as opposed to capacitors, collects excess electricity, resulting in a 50-percent decrease in power consumption while reportedly increasing the power system’s durability.
“Also noteworthy is the timely and high level of technical service at the assembly, training, commissioning and production stages,” Czechowicz adds.
Magnetic Mount Simplifies RFID Use for Dies
8 MetalForming/July 2018
Balluff's new break-off magnetic mount with tag holder allows for simple integration of RFID systems and is ideal for press appli- cations requiring frequent tool changes. The magnetic mounts reportedly ease the alignment of read/write heads and assist in the continuity of the RFID signal while also
The mounts replace conventional insertable connectors, connect and dis- connect RFID readers quickly and reliably, align RFID readers for tag detection, and include positive stop for damage protection.

 The new press, a MSD 630 model, produces parts from sheetmetal in thicknesses from 0.5 to 6 mm. Press-line automation ensures that operators need not intervene in the process until a finished part exits the line, according to Jan Czechowicz, Plasmet general manager.
“The operator's work consists mainly of setting parameters and observing the process,” he says.
The variable nature of the slide has enabled the shorter cycle time, Czechowicz reports, while improving part quality.
“This is particularly noticeable with deep-drawn parts,” he offers.

The controller also allows users to independently skip press cycles for preprogrammed stroke counts.
 protecting the heads from accidental damage.
“Whether used in a die-identification application to ensure that the right die is loaded for the right job, or for a work-in-process application where the workpiece is dynamic, the magnetic mount ensures that the reader and the tag maintain constant communication,” says Wolfgang Kratzenberg, Balluff RFID product marketing manager. “In addition, if the operator fails to disengage the reader, the magnetic mount simply breaks away from
