Neff Press Custom Applications: High Speed Stamping
Final Product: High Speed 5-Ton D-Series Press
 Our
Mission: A major government supplier contacted Neff to build
a press capable of producing high velocities during rapid advance
and return (75 inches per second/ 4500 inches per minute). Neff
was also asked to provide the tooling for there application. The
customer required 5 tons of force with B-Gate guarding to protect
the operator.
Our Solution: Neff Press Inc designed and manufactured (1)
5ton c-frame press with the following specifications: Overall system
footprint 68” x 48” x 98” Tall. The gap opening
has 22” daylight, 7” stroke, and 7” Throat. The
press used a 2hp power unit with a unique hydraulic circuit to generate
the required velocities. Neff used a 20 gallon reservoir, a 2hp
main pump and a 2.5 gallon accumulator with kidney loop filtration
to achieve the speeds. The system required a air cooler and a special
cylinder was to handle the mechanical shock. Neff provided fork
lift holes in the bench assembly for easy mobility.
The press controls system consisted of an Allen Bradley PLC. Neff
provided Dual Anti-Tie down controls, distance reversal, and B-Gate
guarding to protect the operator. Neff provided start-up & training
during run-off and on-site at the customer’s facility.

Project: Special 100Ton C-Frame Press
Glass Scale Linear Transducer
4-Post Guided Tool Mounting Plate
Special Omron Electrical Controls
Our Mission: The customer, a world leader in supplying security
systems and products to the retail industry required a press that
would be easily integrated into their automated cells. Communicating
with a Robotic pick and place unit, vision system, and a staging
index unit, were criteria for the controls on this press.
The solution is a very large, specially designed 100ton C-frame
press with design features including extended daylight, extended
throat and extra stroke. The press had a deflection of .0002"
per inch of throat (press had 16" of throat). The customer
had a large precision die that had clearance of .001" between
the upper die shoe and the lower shoe. The press is also equipped
with an oversized four-post guided tool mounting plate to accommodate
the large tool that the customer runs in the press.
The hydraulic unit was designed with Neff's standard 50 horsepower
dual stage regenerative hydraulic circuit to achieve the cycle rate
required. Neff's press performed a 14" total stroke, with 2"
of work in 2.9 seconds (higher cycle rates are available).
An Omron C200H PLC, Omron remote I/O, Heidenhain glass scale, and
other critical components were in an oversized electrical enclosure.
Two certified Neff Press Technicians provided rigging support,
start-up and integration services for this equipment. The press
was designed to simplify the integration process as much as possible
and the success of this project is proven with our South Florida
customer's recent purchase of their seventh press.
Final Product: Medical Device
 Our
Mission: Our customer, a medical equipment supplier, located
in the Midwest approached Neff Press to design two 15-ton high-speed
hydraulic stamping presses. The platen dimensions were 20"
x28" in between the pins and were nickel plated for anticorrosion
purposes. Neff designed the hydraulic power unit around a special
long lasting single stage pump (9.4 GPM) with a 20HP electric motor.
Neff designed the press with a special RexRoth directional valve,
which could tolerate the high flow rates required in this application.
A positive stop cylinder was supplied for position control and to
generate higher speeds. Eventually, both of these presses were integrated
with a roll feed system.
The customer required a remote power unit (on casters), and control
enclosure. All hydraulic connections from the power unit (3 total)
to the crown of the press were to be quick disconnect. The electrical
connection, both main power supply and the control wiring were integrated
into a mixed power connector to make changeover and maintenance
time minimal. These presses can be disconnected from the main control
enclosure and the power unit, and another power unit/control center
back on line in less than 2 minutes. The presses were designed to
run (3) 7-hour shifts, 7 days a week.
This customer had bought two similar presses from Neff over 8 years
ago and came back for this second application. Neff designed the
new presses to achieve 100 Strokes Per Minute, with a ¾"
total stroke and ¼" of it being full tonnage (higher
speed presses are available). These presses replaced mechanical
presses that were not producing the required part quality. Neff's
hydraulic presses and the unique control of hydraulic presses offered
this customer higher overall productivity.

 Our
Mission: Our customer, a global (Fortune 50) consumer products
supplier, needed another “High Speed” 40 ton 4-Post
press to stamp security tags. It was critical that the press be
accessible on all four sides for other automation and scrap removal.
A robot would feed the press from the front, roll feed would flow
right to left, and scrap removal would occur on the backside of
the 4-post press. Because of shipping container criteria and height
restrictions at the Pacific Rim facility the power unit could not
be crown mounted.
The Solution: Neff supplied a H40-30M hydraulic
4-Post press with several unique criteria. The bed size was 33”
L-R x 33” F-B with 30” of daylight. There was a cut-out
in the bottom bolster for a vision system to be mounted. For access
and height restriction reasons, Neff positioned the reservoir underneath
the bottom bolster and it was shaped like a horse shoe to give access
to the vision system. The power unit (motor/pump assembly) was mounted
externally (upside down) to give full access to all four sides of
the press. This was critical for the customer and their peripheral
equipment that was integrated (feed system, robot, vision system,
and scrap removal).
The press was able to complete a 12” total stroke, with 2”
of work in 2.9 seconds. Our special 30 HP power unit generated ram
speeds in excess of 1200 IPM. Neff included a special hydraulic
pump and valve package that nullified the shock created after blanking
the product. The springs in the customer’s tooling created
a significant load just after blanking the product. Neff designed
a special decompression hydraulic circuit and timing sequence to
solve the problem. In addition, this customer required an Omron
PLC (C200H Series) and several other brand specific components for
part consistency for the entire work cell. Neff has serviced this
customer throughout the world at their various manufacturing facilities.
 Our
Mission: The end customer, a snowmobile manufacturer needed
a high speed press with a unique frame to rivet and stake the tread
on snowmobiles. Neff designed the frame as an “E” style
to allow loading from the front and the 10 ton rams would actuate
from the bottom and top during the application. The press needed
to have access for a conveyor running front-to-back. They requested
a separate hydraulic circuit to control die clamps and a hydraulic
motor which ran peripheral automation. Lastly, the press needed
to complete a cycle (both rams travel 2”, with .3” of
work) in less than 1 second.
The Solution: Neff supplied a Special “E”
press with guided platens on each cylinder. It had 15” throat,
18” of daylight in each “C” opening, a 7 ¾”
pocket in the center section and a cut-out in the back plate for
conveyor access. The power unit was a special 10HP high speed system
with a separate hydraulic circuit/manifold to run the die clamps
and customer supplied hydraulic motor.
 100-Ton
STAMPING PRESS
Servo Ram Control
Electronic Speed & Tonnage Control
Final Product: Magnets
Our Mission: Neff’s customer, a specialty
stamper, required a press for a high speed precision stamping application.
The customer needed a press that could precisely stamp magnetic
material. The total ram travel distance for the application was
½” and necessary repeatability was .005”. The
customer required 60 cycles per minute in continuous mode to meet
their production target.
The Solution: Neff supplied a 100-ton four-post
column press with our Servo Ram Control system, and proportional
valving for electronic speed and tonnage control. The press was
controlled by an Allen Bradley SLC 5/05 series PLC via a PanelView
600 MMI and equipped with a load cell, linear transducer and servo
valving to provide stroke repeatability to customer’s .005”
specification. The PLC could also accommodate up to 99 job recipes
for customer’s various different parts.
Neff also provided hardware and programming to integrate the press
with customer-supplied roll feed.
Neff has over 40 years of experience manufacturing, engineering
and integrating industry standard components to solve customers
manufacturing needs. Contact Neff Press at 800-325-8612 for further
details on this application or on many others.
