ML-7320DL-3D．7350DL-3D
The ML-7320DL-3D/7350DL-3D is a fully air-cooled fiber laser marker best suited for marking characters on small metal and plastic parts, black marking on stainless steel, engraving on aluminum, and other types of ablation processing.
By changing the laser's focal distance with a newly embedded adjustable Z-axis feature, it is possible to achieve highly legible markings (without distorting characters and figures) on workpieces that are uneven or have cylindrical or inclined surfaces.
Contributes to maintaining processing quality by checking the laser power via the power monitor that comes as standard.
We hope that you have a positive experience with these highly functional laser markers that are now even easier to use than ever.
A new generation of fiber laser markers that are easier to use and have high-quality laser beams and excellent laser oscillation efficiency—which is characteristic of fiber lasers—is now on the market.
▶ Features
◆Employs an F-theta lensless structure using the variable Z-axis to achieve high-quality processing on uneven,sloping, cylindrical surfaces on which the focus distance varies.
◆Accommodates 3 types of heads depending on the lenses which have different specifications (processing area:300 mm square or 200 mm square or 120 mm square.)
◆20W or 50W high power fiber laser oscillator enables deep engraving of aluminum and black marking on stainless steel at high speed.
◆500kHz high repetitive frequency produces marking with a high level of visibility on plastics at high speed.
◆Distance pointer makes it easy to position a focus point.
◆Contributes to maintaining processing quality by checking the laser power via the power monitor that comes as standard.
◆LM Draw 6-3D marking software compatible with Miyachi’s other markers is installed.Data transferring, data sharing and converting from other markers can be easily done.
◆Fully air cooled to reduce installation and maintenance costs.
◆Long-lasting laser diode unit reduces maintenance costs.
◆Environmentally-resistant strengthened head：IP67G、IP**G
▶ Fiber laser
The features of high beam quality and high energy conversion enable high-definition marking and processing with energy saving.
▶ 3D function
An f lens-less structure is adopted with variable Z axis control. Stepped surfaces, included surfaces, and cylindrical surfaces can be marked by changing the focal length.
▶ Guide Light
Guide light indicates a marking position on a workpiece.
▶ Full Air Cooling System
Cooling by a motor fan. No cooling water is necessary.
▶ LMDraw-3D
Marking software for 3D fiber laser markers. The variable Z-axis control function is added.
▶ Multimode
This is effective for applications that require energy over a wide area, i.e oxide marking.
▶ Maintenance free
Since no consumable parts, other than LD, is used, the interferance by the maintenance work would be greatly reduced.
▶ LM Draw6-3D the latest marking software
Employs an F-theta lensless structure using the variable Z-axis.
This easy-to-use marking software is compatible with AMADA MIYACHI’s other laser markers. The data made by the previous version of the software can be automatically converted.
Drawings, letters, and 2D codes can be easily designed and marked by laser.
▶ Applications
Marking on electronic components, electric components, medical equipment, plastic parts, and silicon wafers. Black-marking on stainless steel parts. Deep-engraving of aluminum parts. Removal of coated paints on components. etc.
