STANDARD EQUIPMENT INCLUDED IN THE MODEL 645LR ATC
Model 645 Hydraulic Rotary Ram Punch Press
The Model 645LR Press with laser-cutting capability that constitutes the nucleus of the M645LR ATC Flexible
Fabricating System is a large stationary hydraulic press of C-frame structure. The all-welded frame of the press
is designed to be mounted on the surface of the shop floor. It is built to withstand the stress of 40 tons (360kN)
of punching force. The press has a programmable hydraulic-pressure switch circuit, which permits ram reversal
at preset pressure settings (for use in special operations such as counter-sinking and louvering).
This 40 tons (360 kN) press has a table measuring 108” (2743 mm) along the X-Axis and 60” (1524
mm) along the Y-Axis. It can punch 5” (127 mm) holes in material up to ¼” (6 mm) thick and
smaller holes in material up to ½” (12 mm) thick (maximum thickness permitted).
The rotary ram feature permits the ram to be rotated in increments of .01 of a degree or greater. The rotational
accuracy that can be attained is + .05 of a degree.
The largest diameter of punch that can be used when the rotary ram feature is utilized is 2” (50 mm)
or an equivalent size in shaping tooling. This feature permits the punching of material up to the maximum thickness
allowed by the machine for standard punching operations.
Laser Cutting System
The standard laser of the M645LR ATC is the Rofin Sinar Model RS 1200 Laser which has a 1.2 kW output. Its
main constituents are the laser head and the power supply cabinet. The system also includes the focusing head,
beam delivery system, dust filtering and exhaust system, collector assembly, and the chiller.
175 Station Automatic Tool Changer
The standard Model 645L Flexible Fabricating System has 175 Station Automatic Tool Changer. This can be replaced
with a tool changer with 80, 125, or 175 stations, if a greater tool-storage capacity is required by the customer.
Hydraulic Power Unit
The standard M645LR power unit has a 40 horsepower open drip proof motor. Special motors can be furnished as
an option specified by the customer. Hydraulic oil is supplied with the unit.
The power unit consists of three pumps mounted in tandem and provides power for all punching, stripping, and
material-clamping functions and power for the tool changer.
Hydraulic Work Clamp Assembly
The two hydraulic-powered work-clamps (also referred to as material clamps) are located in front of the back
gauge rail at the back of the table. They serve to move the work piece back and forth along the X-Axis. Their
position is adjustable and they can grip material up to the ½” (12.0 mm) maximum thickness permitted
for the M645LR ATC without special setup.
A dedicated pump (one of those mounted in tandem in the power unit) through a double-acting cylinder produces
a gripping force of approximately 2,500 lbs. (1134 kg) at each clamp. The clamps open automatically at the load
and unload positions. Clamp-location protection is programmable through the CNC. Both hardware and software are
involved in clamp protection, through the automatic clamp verification cycle.
Tooling System for 645LR ATC
The 645LR ATC utilizes the 36TC style of punches and 34 style of dies.
Tooling furnished with the 645LR ATC includes a punch insert holder and inserts and dies for 5/16” and ½” diameters.
One rotary die adapter for 2 ¾ O.D. dies is also furnished with the 645 LR.
To aid in machine and tooling set up, an alignment tool assembly, which consists of an alignment punch and
die, a bar, and a punch gage is furnished.
Die adapters, stripper rings and punch rings must be furnished by customer.
Voltage Control Package
The voltage control package contains all the components in the system that are voltage sensitive. The end user
(customer) must specify at the time of ordering what the main power supply to the machine will be.
Programmable Hydraulic Pressure Switch Circuit
This serves to reverse the Ram at a preset (adjustable) pressure. It is used for countersinking, extruding,
coining, and louvering operations.
Programmable Repositioning Assembly
This assembly permits the work clamps to be repositioned on a standard-size work piece for punching and cutting
in areas that would otherwise be in clamp-interference zones and also permits repositioning for work pieces that
are longer than 96” (2438 mm) along the X-Axis.
New Lapis® PC800 Control Only
The Lapis® PC800 Control has helped fabrication companies greatly improve their productivity and lower
maintenance and downtime costs. The Lapis® PC800 Control is a mature, field-tested control with units throughout
the U.S., Mexico, and Canada.
The Lapis® PC800 Control is a turnkey package with no time required to write ladders, interface wiring,
etc. The Lapis® PC800 Control is plug and play, i.e., it connects with pre-engineered I/O and cables. In
most cases the installation can be complete in one day in the field (control only).
The Lapis® PC800 Control is a pure PC based control with open architecture, both hardware and software.
100% elimination of all Fanuc components; i.e., monitor, control board, cables, power supply, servo motors,
servo drives w/Full Control.
Operates under Windows NT™ and is network ready at installation.
Easy to use touch screen standard PC monitor with graphical interface programming, no M&G code generation
required for punch press applications.
Up to 150% improvement in X/Y punch press table speeds over original factory performance. High Speed Package
only.
On-screen diagnostics in plain English.
User benefits: improved productivity, unlimited part program storage, easy to use graphical interface software,
major maintenance cost savings, no proprietary electronic parts, low cost, locally available, standard PC components.
Programmable Small Parts Drop Table
This table provides a means to drop small laser cut parts or scrap pieces out of the material skeleton into
a parts box or some other type of container. The size of small parts or scrap pieces that can be removed by this
method is up to 18-inch square.
Vacuum Slug Removal System
This system utilizes a sealed slug holding compartment that is connected to the machine vacuum system. This
vacuum assists in pulling the slug away from the end of the punch so that the slug is not pulled back through
the die to catch on the moving skeleton that the slug came out of.
Punch Lubrication
The punch is automatically lubricated at a pre-set stroke interval or may be manually activated by a pushbutton
on the CNC control. The system uses an oil mist laden stream of air to completely surround the punch with
lubrication each time the cycle is actuated.
Outfeed Carousel System for Small Parts
The carousel consists of 10 sorting stations for parts up to 18” (457 mm) square or for scrap cut-outs
dropped through the trap door. The system also includes an auxiliary ball-transfer work table and an operator-controlled
retractable unload station for unloading the bins as they become filled with parts. The unload station
has an idler conveyor that is 6 feet long. A light curtain is directed across the top of the bin in the parts
load position to indicate to the operator when the bin is either full or if a part did not fall into the bin
properly, which will cause a jam if the carousel is rotated in that condition. |
