JK704 =
High Performance
Deep Penetration Drilling
Precise and Powerful Cutting and Welding
JK704 Process Flexibility
The JK704 laser combines 20kW peak power with low-divergence (LD) resonator optics to generate a high-intensity laser spot. Guaranteed top-level performance for a variety of activities, including:
- Drilling holes up to 75mm (3″) in length.
- Drilling 3mm (0.12″) long holes at 10 holes/second on the fly.
- Cutting at 3m (120″)/min or to 20mm (0.8″) in depth.
- Deep drilling: A long depth of focus enables deep holes to be drilled with reduced taper.
- Special pulse-shaping techniques can be used to improve the geometrical quality of holes drilled by single laser shots “on the fly”.
- High power welding: When the LD optics are removed this laser offers a welding performance in excess of the JK701.
Turnkey Machines
The laser can be fitted to an array of standard or customized turnkey multi-axis machining centers. Details provided upon request.
Although the JK700 Series are Class IV/4 lasers, when they are augmented with safety enclosures they can be compared to Class I/1 Safety Standards.
