Tekna's Model TK441/2 Four Axis Machining Center enables companies to increase productivity and reduce expenses by replacing two traditional machines and two operators with one Tekna machine and one operator. It is designed for drilling, conventional milling and copy milling operations in aluminum profiles. Other materials include steel profiles, plain or steel reinforced PVC profiles and various other plastics or wood.
Quality
The TK441/2 represents the knowledge of over forty-two years experience building machinery for the fabrication of aluminum extrusions. All welded steel fame construction, precision ground and hardened guides, high RPM electrospindles, extremely fast axes travel speeds, and standard conversational graphical user interface all combine to form a high quality machine that is robust and easy to use.
Application
The TK441/2 has been well received in a wide variety of industries. With over 50 machines installed worldwide, they are employed in the production of curtainwall, windows, doors, trains, cars, busses, trucks, aircraft, furniture, power couplings, telecommunications infrastructure, and more. Versions range in length from 11 feet to over 78 feet X axis capacity and have been offered in both single gantry and dual gantry configurations.
Productivity
With standard TWIN mode (pendulum) capability and optional parallel pneumatic vise clamping, the TK441/2 is really two machines in one. While one side of the machine is working, the other may be loaded and unloaded. By utilizing this approach to machining, companies are increasing productivity and reducing expenses by replacing two traditional machines and two operators with one Tekna machine and one operator. Combined with extremely fast motion on all axes (up to 4.3 feet per second), automatic clamps positioning for quick changeover between jobs, the ability to call programs through bar code scan or electronic data interchange with production systems, and the capability to link to robotic material handling systems, every aspect of the machine is designed for lean manufacturing.
