Advantages of finishing metal products by Kern laser:

  • Perfect registration of cutting to graphics and printed boarders.
  • Perfect registration of holes to shape profile.
  • Perfect alignment of holes to the customers product.
  • Perfect smooth edges, corners and holes i.e. no hand clean up required.
  • Greatly reduced risk of in process damage (scratches).
  • Reduced waste, only narrow gutters required.
  • Reduced waste, less finishing process rejects.
  • Reduced risk off loss of data merge plates in finishing processes.
  • Reduced time spent sorting data merge plates.

Nitrogen assisted laser cutting (giving an excellent dross free finish quality):

Stainless Steel up to 2.0mm

Aluminium up to 1.6mm

Brass up to 0.5mm

Acrylic 6.0mm (6.0mm up to 25.0mm without the ORCamera fitted)

Wood/MDF 6.0mm (6.0mm up to 25.0mm without the ORCamera fitted)

OptiFlex50 features:

K-VISION CAMERA

The K-Vision package is a fully integrated hardware and software solution that allows for accurate cutting of digital and screen printed graphics. This process starts with a nozzle mounted camera which automatically measures the dimensions between registration marks on printed materials. The system then uses these measurements and the registration marks of the original cutting file to compensate for distortion and rotation. The slight adjustments that k-vision makes to the cutting file results in a perfectly matched cutout in the material being processed.

Clean and Accurate Cut

The high pressure assist gas (nitrogen) is injected through the metal cutting nozzle. The result is a dross free cut edge which requires little to no de-burring. A pierce dwell and variable pierce assist pressure are adjustable within the KCAM laser software. The servo motor motion system is capable of tight tolerances and accurate positioning.

The Automatic Focusing Height Follower, is one of the key elements for optimal metal cutting. The cutting nozzle is controlled  by a capacitance sensor. The laser focal point is fully adjustable to suit the material being cut. As the cutting process begins the height follower will track the surface of the metal and adjust the nozzle maintaining a constant focus point while the metal is being cut.

Intricate Cutting

The Kern laser is capable of cutting thin gauge metals with detailed designs. A laser beam cutting kerf of just .004” allows for the most intricate of cuts to be made. These tasks are often difficult or impossible to perform with a high powered kW laser as they are unable to cut with a stable power level resulting in blow-outs or heat affected zones.

Metal Etching/Marking

This versatile machinery will etch dark durable marks onto reflective metals (stainless steel and aluminium) with the use of a laser marking spray. A few of the most common metal etching applications are for variable data applications such as creating bar codes and asset tags. Stainless steel can be also be marked dark with the use of an oxygen assist gas, this will give a nice dark almost black image, though not durable outside (we have not installed oxygen).
