SPL270 History
First ‘Abbund’ machine
The first attempt to build an “abbund” machine resulted in 1982 in a machine consisting of a saw and a roller conveyor with folding stops.
The saw was positioned in angle and centerline but the length positioning was still done manually by pushing the workpiece against one of the folding stops.
The operator set the stops in advance to the appropriate positions using a measuring scale.
When the material was to be cut, the desired fence was lowered and the material was pushed against the fence before the saw cut was triggered.
The machine could also be equipped with drilling and milling units.
SPL 270-1
The first real ‘abbund’ machine was first presented in 1984.
The machine was equipped with a real control system for automatic positioning of the workpiece.
With the help of a small keyboard and a monitor, the machining operations could be programmed and saved on the machine.
The basic plant was equipped with a gripper for positioning the workpiece, a saw that was positioned in angle, center and tilt, as well as a milling and drilling unit.
Most plants were equipped with additional machining equipment such as
Most of the plants were equipped with additional machining equipment, such as notching cutters, face milling cutters, end mills, marking units and extra drilling units.
So did some machines for blockhouse production.
The machines were continuously improved and the degree of automation was gradually increased.
SPL 270-2
In 1988 a new control system was developed with the possibility to handle RAM cards.
Burmek developed an office program that could be used to create and save production programs on RAM cards.
The RAM cards could then be plugged into the machine where the machining programs could be loaded for production.
This also made it possible to generate production programs directly in the CAD system and then load the code directly into the machine.
The SPL270-2 machine also got a new positioning system because the company Hunddegger applied for and received a patent on the solution that Burmek used in the SPL270.1 machine.
SPL 270-3
The SPL 270-2 was replaced in 1989 by the SPL 270-3, which had a new positioning system and a traditional saw table.
The machine also received a newly developed milling unit that could be positioned automatically in three dimensions.
The degree of automation was raised once again.
SPL 270-4
The system consisted of a saw, which could be positioned at an angle and a center position. The longitudinal positioning of work pieces was not yet implemented. The machine was provided with a number of pneumatic stops, which were manually positioned on a guide rail with the help of a scale. In the production the desired fold down stop was activated and the work piece was pressed against the stop before the saw cut was executed. The system could also be equipped with a drilling and milling unit.
