•Machine axes are moved by Servo motor system (3 Servo motor controlled axes)

•Specially developed paralell welding technology that improves welding quality

•Internally engineered design for automatic selection of 0.2 and 2 mm welding range

•Beckhoff brand, high performance industrial PC operated by Windows XP Embedded. Fanless motherboard system works between 0°C – 55°C, and it comes with a 15” touch screen display

•Data transfer via ethernet network connection, wireless network connection or USB interface

•Welding parameters are defined by the user for every individual profile(up to 10,000 profiles)

•Welding temperature, melting and welding times can be adjusted individually for each profile type.

•All machine axes are moved by hardened steel ball screw which provides accuracy and durability.

•PC controlled (PID) heat control system to obtain strong welding results in compliance with standards.

•Summer / winter working mode is automatically selected,so the temperature adjustment is done easily

•Horizontally placed strong mechanical heating plates distribute heat homogeneously without being affected from difficult working conditions.

•Easy and fast change for teflons by specially designed roll up teflon system.

•Easy and fast change for welding moulds

•Works effectively by compressed air supplied to the system

•White or colour profiles can be weld with the same sensitivity

•Central lubrication system minimizes maintenance time

TS 820 Turning Station with the Robotics Arms;

•High speed and high accuracy turning operation via a robotic system with strong and fast mechanical turning arms

•Stable turning process with highly durable turning arms

•Turning speed calculation is done automatically for each frame’s geometric shape, reinforcement steel weight and all other factors included.

•All machine axis are moved by hardened steel rack and pinion gear system which provides accuracy and durability

•Turning robot spends the minimum energy and the least amount of time by synronochizing its actions with the CNC machine’s fence system.

•Its compact design allows it to occupy the smallest working area possible, which is  12 m²  less than its competitors.

•Turning time is 1 second for small frames and between 1,5 – 4 seconds for all other sizes.

CS 810 Cooling and Buffer Station;

•Works between a corner cleaner and a welding machine.

•Provides cooling time for the profiles coming from the welding machine prior to sending them the corner cleaning machine.

•Cooling time is set through the welding machine’s control panel.

•Helps increase the production capacity by storing the profiles coming from the welder before sending them to the corner cleaner.
