CNC machining

3- and 5-axis CNC material machining

We provide 3- and 5-axis milling services for materials such as tool steel, conventional iron, aluminium, copper, plastics and wood for the energy, toolmaking, aerospace and automotive industries. For more complex products, often only 5-axis milling is suitable. Machining is used to produce workpieces with complex geometries and surfaces that are curved at different angles. Before the introduction of 5-axis machining, the problem with this type of workpiece was solved by 3-axis machining and the use of special tools, which increased the production time and the cost of the finished product. The 5-axis machining also allows for negative wall inclinations. The advantage of this type of milling:

reducing the number of cultivation couplings,
shorter cutting tools,
improved rigidity of shorter tools.

3- and 5-axis CNC metalworking includes:

preparation of the processing programme,
CNC machining of the piece,
final measurements

Dimensions of 5-axis CNC milling workpieces:

x = 500 mm
y = 450 mm
z = 400 mm

Dimensions of the workpiece:

max. diameter = 630 mm
max. working height = 500 mm
max. weight = 300 kg

Dimensions of workpieces for 3-axis CNC milling:

x = 800 mm
y = 560 mm
z = 1100 mm
max. weight = 800 kg

The final dimensions must be checked, as exceptions may occur depending on the machining and the shape of the workpiece.

CMX 800V: 3-axis CNC, processing 800 x 500 x 500 mm, max. weight 800 kg

DMU 50: 5-axis simultaneous CNC, machining 500 x 450 x 400 mm, max. weight 300 kg

Laser welding

Laser shaft welding is a process that welds filler material to a worn shaft or bearing seat.
This repairs the surface, which becomes hardened by the filler material and the process itself, without additional heat treatment.
At the same time, a new shaft is avoided, saving time and money.

Laser welding covers:

pre-sanding of the surface, if necessary,
laser welding with material deposition,
grinding to factory tolerances,
taking the final measurement.

Round grinding

Round grinding is the process of grinding the wound part of the shaft to the final dimension, or correcting the side seats of the bearings to meet the installation requirements. Grinding is possible up to a maximum outer width of 400 mm, an inner diameter of 10 mm to 300 mm and a maximum length of 1000 mm.

Round grinding covers:

grinding to factory tolerances,
taking the final measurement.

Static and dynamic balancing

Static and dynamic balancing of the engine rotor is a procedure we carry out every time we overhaul and rebuild rotors.
Static balancing of the motor rotor eliminates the unbalance that causes vibration at rest.
Dynamic balancing, which includes static balancing, corrects unbalance in the rotation of the rotor.
Both methods are necessary to reduce vibration and wear, which extends the life of the engine and improves its efficiency and reliability.
Static balancing focuses on one plane, while dynamic balancing focuses on two or more planes.
