Chipless technologies

Chipless machining methods do not use material removal by mechanical work. Unlike cutting, they produce virtually no chips.

Chipless metal machining

Chipless machining technologies are more efficient and visually cleaner than conventional or CNC machining. Thanks to them, we can process difficult-to-machine materials. In terms of finishing work, for example, we perform smoothing, rolling, blasting and vibration strengthening. From unconventional chipless machining methods, we provide electrical discharge machining, laser machining, electrochemical machining, chemical machining, as well as ultrasonic machining or, for example, machining using an abrasive stream.

We also offer chipless material cutting by machining (e.g., abrasive cutting and friction cutting), cutting by unconventional machining methods (e.g., electrical discharge cutting, laser beam or plasma cutting), cutting using thermal methods (e.g., using oxygen), material cutting using cold forming (e.g., shearing) or cutting with cutting disks. Our customers most often request bending, welding, sandblasting, and stamping.

CENTES – Hydraulické lisování (1)

We can use chipless technologies

Chipless technologies are particularly important production processes at CENTES.

In relation to chipless technologies, we mainly specialise in:

  • electrical discharge machining (EDM)
  • bending
  • metal welding, oxy-fuel welding, spot welding and MIG, MAG and TIG welding 
  • dry and wet sandblasting, sandblasting of parts and finishing of parts 
  • metal stamping – hydraulic stamping and mechanical stamping

We offer

Metal bending

Thanks to our top equipment, we can bend various sheet metal components with high-quality. We perform bending on a modern hydraulic press at CENTES.


Metal welding

Another way of working with metals is to weld them. The essence of welding is to create a firm connection between two different metal components.

Metal stamping

We offer stamping metal parts made from steel, brass, bronze, copper, and aluminium. We usually press parts for the electrical engineering, automotive and other consumer industries.

Electrical Discharge Machining (EDM)

EDM is a special machining technology whereby the workpiece is not machined by a machine tool, but by small electric discharges.

Dry/wet sandblasting, sandblasting and finishing parts

Dry sandblasting, wet blasting and finishing are finishing processes consisting in surface treatment of a metal semi-finished product using abrasive particles.

Our services

Technical preparation of production

Technical preparation of production (TPP) means detailed technological procedures and activities preceding the production of the ordered component.

Metal cutting

Cutting means machining of a metal workpiece using a machine tool. Metal chips are formed during cutting.

Chipless technologies

Chipless machining methods do not use material removal by mechanical work. Unlike cutting, they produce virtually no chips.


Painting is the final stage of metal surface treatment. In our modern paint shop, we provide powder and wet coating on delivered components.

Electrical equipment production and assembly

We do not focus exclusively on metalworking. We also offer these services for our customers so that they have no need to go elsewhere in terms of electrical equipment production and assembly.

Cutting tools and assembly jigs production

We can produce special cutting tools for sheet metal processing on hydraulic or manual presses. All we need is drawings.
