Product catalog summary
Main Features
  • Cost-effective operation through a fully automatic cycle, segment feeding via belt magazine, and segment positioning by a gripper system. The machine uses an electric drive for blade rotation with a fork-type light barrier.
  • Improved saw blade quality is achieved by precise temperature measurement and control using an optical pyrometer.
  • Optimal brazing results are ensured by adjustable segment pressing.
  • Enhanced brazing joints for sandwich blades through pre-heating of the blade without segments.
  • Improved brazing cycle with up to three heating ramps.
  • Shorter cycle and change-over times due to contact copper cooling cheeks for cooling the saw blank.
  • High efficiency is provided by a high-frequency generator with 10 kVA output power, including an air conditioner.
  • Suitable for saw blades ranging from 200 mm to 2000 mm in diameter (a pit is required for diameters above 1500 mm).
Options
  • Cooling units with different specifications (10 kW, 50 Hz or 11 kW, 60 Hz).
  • Adapter for gang saws.
  • Additional inductor available upon request.
Functioning

The blank is vertically clamped, and diameter adjustments are made via a spindle to maintain a constant working height. Segments are stacked in a belt-type magazine. The brazing process starts automatically with a segment and silver solder placed on the blank, continuing until the entire blank is brazed.

Technical Data
  • Total electric power: 14 kVA, with a supply voltage of 3 x 400 V, 50/60 Hz.
  • Cooling water consumption is approximately 25 l/min, with a recommended supply temperature of 15 – 25°C and a pressure of 4 – 6 bar.
  • Compressed air consumption is approximately 250 l/min, with a pressure of 4 – 6 bar.
  • Suction system connection requires a hose or pipe with an inner diameter of 50 mm and a recommended air flow rate of 600 m³/h.
  • Diameter range for saw blades is 200 mm to 2000 mm, with segment dimensions of length 20 – 50.8 mm, depth 1.8 – 12 mm, and height 5 – 25 mm.
  • Machine dimensions are approximately 1880 x 1350 x 2200 mm, with a weight of approximately 950 kg.

The blank is vertically clamped into the machine. The diameter adjustment is done by means of a spindle at the blank in vertical direction so that the brazing position always remains in constant working height. The segments are stacked in a belt-type magazine. When the brazing process starts, a segment and the corresponding portion of silver solder are put on the blank. Afterwards, the brazing process starts automatically according to the parameters entered before. Then, the blank turns on to the next tooth resp. the gang saw to the next position and the process already described starts again...
