EWAMATIC LINE cutting tool grinder is a 6 axis precision grinding machine. It is a versatile machine in both tool manufacturing and re-sharpening. It capable to produce complex carbide rotary tool, carbide inserts, PCD round tool and PCD/PCBN inserts.
This state-of-the-art medium size vibratory finishing system, complete with an effluent treatment plant, has been designed for research purposes. The vibratory motor speed can be infinitely varied up to maximum of 1,500 RPM; and the direction of media feed can be changed by changing the direction of rotation of the eccentric weights which can be also changed to vary the amplitude of vibration. The central dome can be replaced with fixtured parts such as turbine blisks for in-depth studies.
Ultra-precision machining is a crucial technology for the development of intricate micro-optical-electro-mechanical devices and mechanical components used in photonics, semiconductor, bioengineering, medicine, precision engineering, and telecommunication industries. UPM can achieve such ultra-precision nano-scale material removal process for fabrication of optical surfaces with sub-micron surface form profile accuracy and nanometer surface finish.

The UV DPSS laser has a nano second pulse width, high repetition rate and excellent beam quality with average UV power output of 10 W. As the absorptivity of most materials increases dramatically with wavelength, the material surface absorption of UV energy is much higher than those from a longer wavelength laser such as Nd:YAG and CO2 lasers. This translates into more efficient energy coupling, less thermal damage and a cleaner, narrower cut. The laser machine is ideal for cutting and drilling hard materials which are difficult for other techniques and/or other lasers, such as silicon, glasses and composites, with minimum damage and better quality. UV beams also provide the benefit of smaller kerfs in dicing operations and increases aspect ratios to drilling processes.
CO2 laser is the most popular tool in industrial applications due to its high efficiency, maturity and lower cost. It has a wavelength of ~10.6 µm, which is highly absorptive for all the non-metallic materials. Due to its high power availability and lower cost, it has also found a wide range of applications in processing metallic materials in automotive, marines and aerospace industries. The materials that can be processed range from polymers, metals, semiconductors/ceramics, to dielectrics such as glasses.
A femtosecond laser is a laser which emits optical pulses with a duration well below 1ps, i.e., in the domain of femtoseconds (1fs = 10 power of -15 s). As the pulse duration is shorter than the heat diffusion time during material processing, this leads to minimal thermal-related defects, e.g. material recast, HAZ, shock waves or microcracks. One main feature for such laser is sub-micron features can be produced with high reproducibility.
Excimer laser operates at an UV wavelength (248 nm) that is capable of directly breaking the molecular bonds of many polymeric materials such as polyimide, polyester. As such, it removes materials with a mechanism that is different from conventional longer wavelength lasers. Through direct molecular bond breaking and its very high peak power and short pulse duration, materials are removed by a process called ablation. The point of interaction between the laser beam and workpiece remains at low temperature. Material is removed from the interaction point without being seriously heated and melted. As a result, there is minimum sign of heat affected zone. The laser can also be used for semiconductor processing such as annealing, recrystallisation and dopant activation, etc
The Nd:YAG laser is a versatile cutting, drilling, and welding tool. The laser beam can be focused to a small focus spot (~25-300 um diameter range) for processing while coaxial gas (Helium, Argon, Oxygen, etc) is delivered just above the focus by a nozzle that surrounds the beam to keep the optics clean and improve the process. The temporal profile of the pulse can also be “shaped” to optimize the process and deal with dissimilar materials.
Fibre laser is one of the rapidly growing lasers in the market due to benefits such as high efficiency, excellent beam quality, no calibration or alignment, low maintenance, and small footprint. Fibre lasers is capable of welding, cutting and drilling at faster line speeds along with finer machining capabilities.
The SPI 200 W fibre laser, when focused, can give a spot size of 30 µm for welding of thin sheet materials, such as micro-welding of hermetically seal pacemakers, as well as cutting of stents.

The Rofin Q-switched laser has an average power of 500 W and peak power of 2 MW.
The laser beam is delivered through a square optical fibre and scanner head, giving a square beam spot size of 600 µm at focus. The beam intensity is sufficiently high to ablate materials. It is therefore suitable for material removal processes such as laser cleaning, insulation, and other surface treatment applications.
