The Fully Automatic Operation Tandem Line is a shortened automatic line placing a drill and a saw close together.
The drilling and sawing is made by one program; trim cut pieces are removed automatically - the solution of saving space and workers altogether!
Drilling and sawing are integrated to one program; each program is allocated drill and saw automatically.
Trim cut pieces are also automatically removed while the machines are running.
SHORT CUT PIECES DISCHARGER
Trimmed/short cut pieces are removed automatically from the line; no need to interrupt machine runs.
LAST CUT FUNCTION
The integrated gripper mechanism securely holds all types of trim cuts no matter size, weight or shape. This is integral to the success of fully automatic operation.
CHIP SWEEPER (OPTIONAL)
The chip sweeper removes the drilled chips left on workpiece which damage saw blade edges while cutting.
As the Drill and Saw are placed close together, the workshop space necessary for the line is minimal.
This reduced footprint allows more space for fabrication and welding operations.
■ Variety of Features
SWIVEL OF BOTH DIRECTIONS
For miter cuts, the saw frame swivels automatically: max. 60 degrees clockwise, max.45 degrees anti-clockwise.
The saw frame and base are extremely heavy-duty ensuring a high level of accuracy, efficiency and maximum performance.
WORK FEED ESCAPE
Even the fixed side of the vise escapes slightly for trouble-free work feed.
The raking type chip conveyor endlessly rakes chips out while allowing cutting fluid to drain back into the reservoir.
UNITIZED MAIN VISE AND BASE
DAITO patented unitize vise can clamp the workpiece with 1 ton of clamping pressure, this reduces vibration of the cutting and increases blade life.
The saw frame swivel is driven by a geared motor and pin gears with little backlash; the swivel angle is always accurate.
DRILL SPINDLE PRINCIPLE
The spindles travel all directions and this brings accuracy of hole to hole dimension and higher productivity.
The workpiece positioning error caused by inertia is compensated by the positioning of each drill.
PINCH ROLLER SYSTEM
The workpiece is fed by powerful pinch rollers located on the in-feed / out-feed sides of the machine. Even the heaviest workpiece is fed efficiently and accurately.
AUTO TOOL CHANGER (ATC) / FOR EACH DRILL
Three (3) Independent tool changers of max. 5 tools is mounted by each of the top / left / right drill heads.
Web supports prevent thinner webs from bending under the pressure of drilling. This feature reduces drill bit failure and improves hole quality.
FLANGE SUPPORTS / HEIGHT GAUGES
The Flange height gauges not only support flanges, but also measure flange distortion that might remain after being vertically clamped.
■ Applications of Tandem Line
A full scale beam line is available developing the basic Tandem Line.
Installing a coping machine and automatic in-feed/out-feed mechanism for the next process, versatile full-automatic process line becomes available.
Installing beveling machine, a full scale pre-welding beam line becomes available.
Without the Short Cut Pieces Discharger, the economical line is easy to introduce.
