Single Line 2: Four Head Welding Machine & CNC Corner Cleaning Machine

Single Line 2

Single Line 2 is created with the integration of KD-658/20 Four Corner Welding Machine, CK-187 Cooling Station, CK-180 Faster Turning Robot and CN-772 CNC Corner Cleaning Machine. From welding to cleaning, every stage of the profile processing is controlled by the computer. While the KD-658/20 Four Corner Welding machine starts welding a new frame, the CN-772 Corner Cleaning Machine can start the cleaning process of the frame. With the servo motor rotating robot, the frames are rotated quickly and stably and corner positioning is made. (small frames 1 sec., large frames 1.5 – 4 sec.) Profile information is automatically transferred from the welding machine. Backlash-free gearboxes are used with hardened rack and pinion gear system that provides precision and durability in the axes.


  • Efficient combination of KD-658/20 Four Head Welding Machine, CK-187 Buffer Station, CK-180 Faster Turning Robot and CN-772 CNC corner cleaning machine in one production unit.
  • Welded frame or sash is automatically transferred to the corner cleaning machine with all the data about the profile.
  • All phases of the operation from loading of the profiles to the welding and corner cleaning process up to the unloading of the frames or sashes are controlled by computer.
  • CN-772 Corner Cleaning Machine can start cleaning the corners while the KD-658/20 Four Head Welding Machine starts the welding process.
  • Servo Controlled CK-180 Faster Turning Robot turns the frame or sash at an appropriate speed relative to the size and allows four corners to be cleaned.
  • Corner cleaning machine automatically adjusting of rotation speed with the receiving data from welding machine about geometric shapes, measurements and calculation of reinforcement steel weight
  • High mechanical stability, Servo Controlled CK-180 Faster Turning Robot enables frames fast and stable turning with high accuracy; Small frames: 1 second, big frames: 1,5 – 4 second, the positioning can done by turning the corner
  • Profile identification information is automatically transferred from the welding machine
  • Durable and precision movement of axis due to hardened rack and zero backlash gearboxes used in the gear system
  • Online connection to the entire system, remote detection of malfunctions and maintenance is available
  • The rails are specially coated to prevent corrosion
  • Central lubrication system eases maintenance
CK-187 Buffer Cooling Station
  • Cooling station which transfers the welded frames or sashes from four head welding machine to turning station for corner cleaning
  • Waiting time for cooling is controlled by the computer of the welding machine
CK-180 Faster Turning Robot
  • CN-770/20 and CN-772 CNC Corner Cleaning Machine integrated together
  • Automatically transfers the frame or sash and positions the corner to be processed one by one into the corner cleaning machine
  • Transports the processed frame or sash to the off loading area
Available Options
  • Barcode reader
  • Gasket pressing system
  • Automatic 0,2 mm and 1,2 mm welding seam restriction setting
