Manufacturing of small and large mechanical components

Drilling is considered one of the oldest process technologies in the field of mechanical manufacturing. Ateliers Ehrismann offers a variety of drilling methods:

Form drilling

Drilling process with controlled cutting or feed motion to produce internal surfaces that deviate from the circular-cylindrical shape

Counterboring

Rotary movement to produce a right-angled plane surface

Profile drilling

Method of producing rotationally symmetrical internal surfaces determined by the main cutting edge profile of the tool

Circular drilling

Drilling process for producing a circular cylindrical inner surface coaxial with the axis of rotation of the cutting movement

Screwdriving

Used to create internal screw surfaces (e.g. threads) – feed rate is identical to the thread pitch

Turning is a cutting process in which a workpiece is machined by a cutting motion of a tool. State-of-the-art machines allow us to offer a wide variety of turning techniques:

Long Turning

Workpieces can be made from long and slender parts, such as wire or bar stock.

Facing

In facing, the turning tool creates a cutting motion on the workpiece. In doing so, the bit rotates parallel to the axis of rotation of the shape being machined.

Parting off

The process technology enables us to machine workpieces axially as well as radially. Consistently high feed rates guarantee an increase in productivity.

In milling, the workpieces are machined by single- or multi-bladed tools. Both large and small parts can be machined using this manufacturing technique.

Face milling

The milling process is used to produce flat surfaces such as shoulders, sealing surfaces on flanges or housings for electric motors.

Circular milling

Circular cylindrical external or internal surfaces can be produced on the workpiece.

Roll milling

The process is used to create splines on gears.

Grinding is a machining process that uses a multi-bladed tool. We use bonded and loose grinding tools for this purpose.

Surface grinding

This manufacturing process is used for flat surfaces and enables the surface finishing of workpieces with micrometer accuracy.

Cylindrical grinding

This technique is used for machining cylindrical, tapered or conical workpieces when the highest possible surface accuracy is required.

Two or more materials can be joined together by welding. The manufacturing process can be divided into two types:

Fusion Welding

In this welding process, two workpieces are heated to the melting point and fused together.

Pressure welding

The materials to be welded are pressed together by machine with great force. Two materials with different melting points can be joined together.
