Grinding Technology

The diverse areas of application in grinding technology also demand a high degree of flexibility from the spindle system. Our high-frequency spindles offer a variety of different uses and are accurate and safe in any area.

Dental Technology

Modern milling units in dental technology have to show what fully-automated production can achieve in the smallest spaces:
Up to 7 traversing axles are available for machining tasks.

Tool and Mould Construction

Tool and mould construction have a special place in the manufacturing industry as almost every work piece is unique. The technical requirements for production are often complex and require the spindle used to be highly flexible and reliable.

Robot Applications

Processing material using a robot poses the highest demands on the spindle system used. Our focus is on absolute precision. HPT’s line of highest quality GERMAN and SWISS precision motor spindles such as IMT, JAEGER, MEYRAT, SLF and Zwanzig are the right choice as far as weight, interfering contours and bearing rigidity are concerned.

Conductor Boards

The manufacture of conductor boards is a very complex sequence of production steps which must be coordinated exactly with each other. One of the most sensitive steps is depanelisation, i.e. the separation of the conductor boards processed in a compound structure. On the one hand, separation must be stress-free and on the other hand, it must be intelligently linked with the directly connected steps “testing” and “sorting”.


A process which revolving parts (screw, bolt, axis, etc.) are machined by removing material from metal bars with a spindle.


An operation which consists of machining flat surfaces on a machine tool equipped with a spindle dedicated to this application. On a lathe, dressing corresponds to the tool moving along an axis perpendicular to the part’s axis of rotation.

EDM (Electrical Discharge Machining)

EDM (Electrical Discharge Machining), is a process which consists of removing material from a part by using electrical discharges.


Is characterized by the recourse to a machine tool : the mill. The classically used tool is the mill carried by a spindle.

In milling, the material removed as chips results from the combination of two movements: the rotation of the cutting tool placed on a spindle, on the one hand, and the moving forward of the part to be machined, on the other.


Drilling is a machining process which consists of making a hole in a part. This one can pass right through the part or not emerge from it. In the latter case it is called a recessed hole.

This hole can be made by a drill on a spindle, a drill bit on a crankshaft, cut out between a punch and a die, laser, electro-erosion, ultrasonic device, etc.


Cutting is a machining operation intended to remove material by using a spindle or a cutting tool. The essential application is the cutting of gearings.


Removing material with a spindle to obtain cylindrically and/or conically shaped parts. The part to be machined is fastened in a clamp, a mandrel or between tips.

In turning, the cutting movement is obtained by rotating the part fastened between the jaws of a mandrel or in a specific clamp, while the advancing movement is obtained by moving the spindle. These two combined movements allow removing material in the form of chips.


Cutting into the unprotected parts of a metal surface to create a design in the metal.
