FAQ by subject area
What is laser cutting?
Precision laser cutting is a precise and efficient process in which a high-energy, thermal laser beam is used. Materials are cut without contact at high cutting speeds and are used in various industries. In laser cutting, various processes such as CO2 lasers, fiber lasers and Nd:YAG lasers can be used to cut a variety of materials such as metals and thin sheets. Thanks to CNC (computerized numerical control) focusing of the laser beam, fine cuts with high precision, repeatability, short set-up times and virtually burr-free cutting edges can be achieved.
What is laser precision cutting?
Laser fine cutting is a specialized form of laser cutting that makes it possible to cut complex shapes, intricate contours and individual patterns. By using state-of-the-art laser technology, the material is cut with minimal heat generation, low roughness and high accuracy without compromising the material integrity. This method is particularly suitable for cutting intricate parts with complicated structures.
There are many areas of application for laser fineblanking, ranging from the manufacture of microscopically small components for medical devices to the production of intricate pieces of jewelry. Laser fineblanking is also used in the manufacture of electronic components, precision tools and fine mechanical components.
Thanks to the precision, versatility and efficiency of laser fineblanking, DeSta::Microcut customers can expect high-quality, customized solutions for their individual requirements. Using modern and versatile fiber laser machines, the company is able to implement even the most demanding projects with the highest precision. See for yourself!
What is the difference between laser cutting and laser precision cutting?
Laser cutting is a process in which a laser beam is used to cut materials precisely. Laser fine cutting is a specialized form of laser cutting that enables particularly fine and precise cuts. Laser fine cutting is characterized by greater accuracy and better control over the cutting process. This enables more delicate contours to be cut with reduced heat input.
Laser precision cutting cuts thin materials with high precision and tight tolerances without deforming or damaging the cutting unit. This allows complex shapes, the finest structures and intricate details to be realized. Together with its high quality standards and expertise, DeSta::Microcut is your partner for customized solutions and individual requirements.
What are the advantages of laser precision cutting?
- Production of filigree geometries possible
- High flexibility Easily changeable geometry thanks to CAD/CAM connection
- Good material utilization Clean, mostly rework-free cutting edges
- No tool wear
- No tool changes required
- Hardness of the workpiece not relevant
What are the disadvantages of laser precision cutting?
Laser fineblanking cannot be used for all materials. These include, for example, materials that vaporize too quickly or are flammable, such as plastics or rubber. Transparent materials cannot be processed with CNC laser cutting either, as the laser light is not absorbed. In such cases, other cutting techniques, such as water jet cutting, are more suitable.
Another disadvantage is that some materials can develop a so-called heat-affected zone, which can lead to deformation or other undesirable effects. In addition, color changes or peeling are possible. With coated materials in particular, the DeSta::Microcut team has succeeded in minimizing negative effects through many years of experience and testing.
Precision (laser) cutting
Precision cutting, also known as laser fine cutting, is a cutting process in which a thermal laser beam separates materials such as metal. This process makes it possible to create complex and precise cuts with little thermal influence, resulting in clean, smooth edges.
By using CNC-controlled laser cutting machines, a wide variety of shapes and patterns can be realized with tight tolerances. This enables the production of individual and customized products with high accuracy and virtually burr-free cutting edges. Thanks to its high repeat accuracy and fast processing speed, precision cutting is ideal for the series production of small parts. Precision laser cutting is also used in prototype construction and for one-off production.

What is the difference between micro waterjet cutting and waterjet cutting?
A high-pressure water jet is used to cut materials such as metal, stone, plastic and glass during waterjet cutting. Depending on the process selected, an abrasive, often fine granulate such as abrasive, is added to the water. This technique is particularly suitable for thick materials and enables fine cuts with a very low thermal energy impact.
The fundamental difference between waterjet cutting and micro waterjet cutting lies in the scaling and accuracy of the application. Micro waterjet cutting is a further development of waterjet cutting and is characterized by greater precision. This method is particularly suitable for brittle materials, very fine cuts and applications where high cutting quality is required. The diameter of the water jet is significantly reduced in the micro version. This is particularly advantageous when processing sensitive materials or producing delicate components.
Regardless of the process selected, both technologies offer high-precision cutting results with low heat input. Micro waterjet cutting is also specialized in the smallest dimensions.
Are there only standard processes for waterjet cutting?
In order to cut a range of materials with the highest precision, there are two processes in waterjet cutting – pure waterjet cutting and abrasive waterjet cutting.
In pure water jet cutting, soft materials are cut with filtered water at up to three times the speed of sound. Typical materials for this are paper, cardboard, leather and textiles.
In abrasive waterjet cutting, the finest abrasive is added to pure water in order to cut even hard materials precisely. The choice of the right abrasive is crucial and depends on the material to be processed. Due to the high pressure, it is also possible to cut steel and harder materials such as titanium using waterjet cutting.
Deciding on the right method depends on factors such as material type, thickness and desired cut quality. The versatility of waterjet cutting enables DeSta::Microcut to offer a customized solution for a wide range of applications. State-of-the-art waterjet machines make it possible to cut almost any shape with high precision. Whether for industrial applications or artistic projects, DeSta::Microcut offers customized solutions for all customer requirements.
What are the advantages of waterjet cutting?
- Gentle on materials
- Micro waterjet cutting enables all common materials to be cut, including thermally sensitive materials, special materials and exotic alloys in the μm range.
- Low thermal load
- The low cutting force acting on the sheet allows the material to be clamped without tension. The cold cutting process rules out any structural changes.
What are the disadvantages of waterjet cutting?
In addition to the advantages of waterjet cutting already mentioned, there are a few disadvantages to consider that can affect efficiency and lead to a higher environmental impact.
One of the disadvantages of abrasive waterjet cutting is that the cutting nozzles wear out more quickly. This requires regular replacement. Depending on the material, this can lead to longer processing times. In addition, abrasive waterjet cutting of harder materials increases the amount of abrasive particles required, which requires regular replenishment of the abrasive used and can lead to higher costs.
Thanks to its many years of expertise, DeSta::Microcut always tries to weigh up the advantages and disadvantages and minimize any potential impact on the environment.
Waterjet fineblanking & laser fineblanking - which process is better?
Laser fine cutting uses a highly concentrated, thermal laser beam to cut materials. The laser beam generates heat, which heats and cuts the material to be cut. In the case of heat-sensitive materials, this can lead to discoloration and changes in the material properties.
In comparison, micro water jet cutting uses an abrasive or pure water jet, depending on the material in question. With several thousand bar pressure, it is possible to cut ceramics, carbon fiber and other hard materials. The cold cutting process generates minimal heat and therefore does not alter the material.
At DeSta::Microcut, we offer micro waterjet cutting (cold) and laser fine cutting (hot) to best meet specific customer requirements. Both waterjet cutting and laser fine cutting are effective processes for cutting steel and many other materials. The choice of the right process depends on the specific requirements of the material and the desired cutting quality. The team will be happy to advise you on the right process for you.
