b) Basic machine equipment
- Machine portal designed as a stable welded construction to
accommodate a vertical drilling unit.
- Drilling unit, in a positioning slide, running in backlash-free
pretensioned linear roller guides.
- Fast and highly precise drill spindle positioning via ball screw and
servomotor.
- Programmed spindle speeds, which are stored as fixed values in the
operator software, are automatically assigned to the respective
drilling diameter.
- Electro-mechanical drill feed Above ball screw and servo motor.
- Programmed drilling feeds, which are saved as fixed values in the
operating software, are automatically assigned to the respective
drilling diameter. It is also possible to manually increase or reduce
the feed value specified by the programme on the control panel.
- Automatic drill length measurement by laser.
- Automatic tool change for 6 drill bit sizes. The tool changing unit
consists of a disc magazine, which is attached directly to the drill
carriage to achieve the shortest possible changing times.
The speed and feed rate change is automatically linked to the drill
bit change. The scope of delivery includes 6 tool holders.
- Air cooling device with micro-metering system switched with the feed
for drilling tools with internal axial air supply. Cooling is
optionally available for drilling tools without axial air supply.
- Countersinking programme for the drilling spindle
Above drilling depth control for flat countersinks with
interchangeable guide pins0 15 - 40 mm and
for countersinks with0 30 - 50 mm (countersink device required. Tools
and holders are not included in the scope of delivery).
- Self-adjusting vertical clamping device with hydraulic hold-down
device within the automatic cycle control.
- Chip scraper for automatic removal of the drilling chips from the
workpiece surface, within the automatic cycle control. Automatic
height adjustment on material surface.
- Chip holder can be pulled out on both sides of the machine on
rollers, arranged in the machine bed.
- Torch cutting unit for oxy-fuel cutting, attached to the drilling
unit, with remote torch ignition and flame monitoring, including the
necessary cutting nozzles.
Fuel gas: e.g. propane, acetylene.
- Burner height adjustment. Automatic distance control with capacitive
sensors.
- Feed of the flame cutting device via the positioning drive of the
drilling unit.
- Slag trolley for centralised disposal of solids and burn-off, can be
pulled out, mounted on rollers, arranged in the machine bed.
- Length measuring device, consisting of a gripper carriage with
hydraulic double collet on the fixed system side and a hydraulic
single collet approx. 1200 mm away from the fixed system side. Gripper
carriage positioning drive Upper servo motor with absolute encoder and
precision measuring rack. Additional hydraulic collet on the fixed
system side, travelling with the main collet carriage.
- Sheet length measurement with laser light sensor by return travel of
the additional collet on the fixed system side. Position detection of
the lateral sheet edge on the fixed system side in the area between
the drilling support and the flame cutting slot.
- Feeding roller conveyor in a solid, welded construction with
maintenance-free, ball-bearing mounted transport rollers. Vertical
stop cams for aligning the sheets on the fixed feed side. After the
sheet has been clamped by the grippers of the length measuring system,
the vertical stop cams are lowered automatically to avoid a copying
effect of the contour of the sheet edge on the fixed support side
during the machining process.
- Discharge roller conveyor in a solid, floating construction with
maintenance-free, ball-bearing mounted transport rollers, fitted with
intermediate plates
- Tipping device in the area of the outfeed roller conveyor, for
automatic disposal of small parts (approx. 60 x 60 mm min. to 400 x
400 mm max., max. sheet thickness 60 mm) into a pull-out good parts
container.
- Cooling unit for main switch cabinet and switch cabinet on the
machine (required if ambient temperature exceeds + 35° C)
.
- Safety devices such as light grids and fences are included in the
scope of delivery in accordance with CE regulations.
Machine control for KF sheet metal processing centre
hardware
- CNC path control for positioning the 2 axes in the sheet metal
plane:
Y tor the transverse movement of the drilling spindle, optionally tor
the marking device
X tor the longitudinal movement of the workpiece
- Machine control (PLC)
for controlling the machine functions
- Machine industrial PC with WINDOWS XP embedded with keyboard,
mouse,
screen integrated in the control panel, network card
- Remote diagnostics optionally possible (in order of Kaltenbach´s
preferred options):
◦ TearnViewer via the Internet (further information at
.teamviewer)
◦ Via a VPN connection to be provided by the customer (Microsoft VPN
preferred)
◦ Via a telephone line to be provided by the customer (digital,
analogue)
Software
The industrial machine PC contains the steel construction-specific
LANTEK software package for creating programmes for the machine
control. The program, which runs under Windows XP Professional ML,
processes the entered workpiece data and uses it to generate the NC
program for the sheet metal processing centre.
The programme package consists of the following modules:
- Lantek Expert li Cut Plus.
Interfaces:
- Interactive automatic or manual contour nesting.
- Macro language incl. 67 standard macros. Own macros can be created
additionally.
- Collision control
- Economy and grid cutting for waste optimisation
- Automatic remnant panel generation
- Integrated component management and databases for material, panel
and remnant panel stock.
- Optional piercing function or pre-drilling.
- Calculation of component area and weight, cutting times and costs
- List and label printouts
- Automatic management of the number of nested and non-nested
components.
2D CAD module for creating nesting plans, incl. automatic contour
checking and correction as well as automatic dimensioning
- DSTV NC data import
- DXF input/output module
- DWG - AutoCAD import interface
