Micro-machining laser
1 min read
Developed for high speed, ultra-accurate, micro-machining of precision components including a wide variety of materials from stainless steel, silicon wafer, ceramics, polycrystalline diamond (PCD) and cubic boron nitride (CBN), the Sauer LASERTEC 20 FineCutting processing centre is available in five- (P5) or three-axis (P3) versions. It employs high dynamic, direct linear drives and torque motor rotary drives along with state-of-the-art fully integrated 20 Watt Q-switched 500 Watt CW fibre lasers.
Having a portal design, rigidity is high throughout the machine’s working envelope of 200 mm in X, 300 mm in Y and 280 mm in Z, through which, the direct linear drive systems provide an acceleration of 2G in each axis. The stability of the machine is able to ensure a constant contouring accuracy within five microns with a minimum laser cutting gap of 20 microns.
The use of fibre laser technology ensures the beam is of the highest quality, very stable and easy to integrate with options such as CCTV and focus control. During manufacture of the silica glass optical fibres used in the beam transmission, a rare earth element Ytterbium is mixed into the core (doping) enabling it to generate a very high powered beam (M2<2) inside the fibre that enables very high quality and efficient cutting.
This makes the LASERTEC 20 ideal for ultra-small, micro-technology machining and profiling typically demanded in the medical, instrument, toolmaking and precision fine blanking industries that require a high precision prototype or a small batch production cycle capability.
Control is via DMG’s ERGOLine with a 19 inch screen incorporating Siemens 840D Solutionline and includes LaserSoft software tools.
