The JK704 Laser guarantees high performance, offering:

• Up to 20kW peak power
• Low divergence resonator optics provides a high-intensity laser spot
• Long depth of focus for deep drilling
• Can be used for high power welding

 

JK704 Process Flexibility
The JK704 laser combines 20kW peak power with low divergence (LD) resonator optics to produce a high-intensity laser spot for:

● 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

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”.  When the LD optics are removed this laser offers a welding performance in excess of the JK701.

Turnkey Machines
The JK704 can be matched to a range of standard or customized turnkey multi-axis machining centers. Inquire for details. NOTE:  While the JK700 Series are Class IV/4 lasers, when they are completed with the safety enclosure they meet Class I/1 Safety Standards.
