"Removed material - my added value" |
I offer you machining of small and middle-sized parts, and designing, constructing and production of mechanical assemblies.
My customers are for example producers of single-purpose machines and various prototypes, hobby CNC machine builders, modellers and many others.
I'm specialized on single-piece or small-lot production of parts made especially of aluminium alloys, regardless of the complexity.
Take a look at my
machine tools and
products
to determine whether I'm the right manufacturer for you.

|
The accuracy |
 |
|
By default, I work with the accuracy of 0.05 mm. If necessary, I'm usually able to keep the accuracy of 0.01 mm.
On the other hand, it is difficult to keep the accuracy under 0.2 mm for the dimensions above 500 mm.
During the production process, I also take care about other parameters and tricky things such as squareness,
angle precision, parallelism, roundness, centricity, unwanted conicalness, inner edge sharpness,
surface quality etc. The goal is that the final part must always satisfy all the requirements for
functionality, and also troublefree assembly, usage safety and appearance.

What I can't do
My technical equipment is not suitable for the following jobs. That's why I can't offer them as a standalone order.
However, some of these jobs can be done as a partial task within a larger project.
Providing subdeliveries (laser-cutting, anodizing) is only meaningful when combined with further work I can do for you.
