The LMJ is used to cut oscillating monolithic parts with complex shapes without deformation or heat affected zone but with the capacity to cut very thin bridges.

With very short warm-up and set-up times Synova's Laser MicroJet (LMJ) is a flexible and stable tool to cut watch components for luxury watches, no matter if it's for production or prototyping.

The challenge was to slice large CVD crystals (chemical vapor deposition) of up to 25 mm from a single direction and along the largest thickness, with a high quality.

The LMJ is used for cutting components with free froms with high accuracy requirements (± 5 μm) from CVD crystals.

The use of LMJ ensures a high quality coring and slicing process of CVD crystals and smooth surfaces as well as low roughness what requires minimal post treatments.

With LMJ there was an improvement in yield, straightness, smoothness, cracks, and throughput in coring and slicing CVD crystals.

The goal is to get a maximum number of slices out of the HPHT crystal (high pressure, high temperature) and to cut variable thicknesses ranging up to 12 mm.

The aim is to obtain a maximum number of slices from the CVD crystal. Cutting with a constant parallel kerf and without tapering with LMJ ensures a higher yield.

The LMJ is advantageously for fancy bruting due the its perfect cut at the outline of the diamond to create the shape profile. Less post-processing is required.

To link the diamond with the other jewellery part, a hole-drilling process might be required. With LMJ the drilled holes are fully straight, no V-shape, no chipping at the hole entry and exit.
