New Davenport Servo B
Ups Productivity
September, 2003 -- Davenport
Machine, Inc. has successfully reintroduced the Model B
Servo Five Spindle Automatic Screw Machine. The Servo B is
the next generation of Davenports Servo Drive machine and
provides significant improvements in operational speed, user
interface, part throughput, and cost efficiency.
One of the key enhancements of
the machine is the replacement of its Variable Frequency
Drive (VFD) with a new DC Servo Drive for the main machine
drive motor. The Servo Drive eliminates numerous gears and
pulleys associated with the VFD and the previous mechanical
Model B Machine.
The new Servo provides the
following benefits:
-
Reduced following error,
cutting current 3% variations in earlier models to under
0.2% in the new Servo B, thus maximizing part accuracy and
improving configuration integrity in applications such as
threading
-
Provides the industries
fastest index time at 0.3 seconds
-
Eliminates numerous mechanical
parts, thereby reducing maintenance and the cost of
replacement parts
"The
Servo B will have a dramatic impact on our customers'
productivity," said Bob Brinkman, president and CEO of
Davenport Machine, Inc. "New machines purchased today have
proven they can pay for themselves in six months when tooled
and set up properly."
There's good news for users of
the original Model B machines as well. Full Servo Upgrade
Packages are available that will convert existing machines
into Servo B units, allowing them to incorporate many of the
same productivity gains available on new machines.
Operator-friendly
Control
In addition to its drive improvements and the elimination of
internal mechanical parts, the Servo B provides a powerful,
yet user-friendly man-machine (MMI) interface. Its
operator-friendly programming cuts training time from months
to days, an advantage that will have new operators running
machines in no time.
Remote Monitoring
The simple PLC control on the Servo B controls four axes of
motion and permits up to 10 jobs to be stored on the
machine. In addition, the Servo B's optional 10 base T web
PC card brings even more benefits of the digital-age to
operators and management alike. Remote monitoring of all
critical operating functions can now be performed. Functions
such as job status, operational parameters, error reporting,
tool breakage, and more can be viewed from a remote location
or signal messages can be automatically sent.
"Many Servo owners are
successfully competing with China due to reduced cost and
higher productivity," Brinkman said. "and remote monitoring
increases productivity even more knowing that you can check
status and have a remote look at ongoing operations in
real-time.
