HK-CON The company at a glance

The foundation was based on our knowledge and experience in the mechanical and control design of machine tools for the machining of metals. With our solutions concerning the geometrical position of the working spindles and the tools, the highly efficient production of mass turned and mass milled parts is possible.  From the very beginning, we have relied on proven suppliers such as Siemens, Schaeffler, Bosch Rexroth, Festo etc.

By adding automated loading and unloading systems to the machines, further fields of competence were occupied.

Today, plants are no longer conceivable without the use of driverless transport systems, conveyor belts, gantry loaders, industrial robots with various gripper systems, image processing systems and measuring systems. In addition, we have developed our own motor spindles for tools and work spindles, spindles, clamping systems, shaft feed-throughs, tool storage and tool transfer systems.

Our ambition is to always develop user-friendly systems, taking into account the latest technology and costs.

Corporate philosophy

We are mechanical engineers with heart and soul. For over 20 years, the name HK-CON has stood for reliably good performance. We fulfil our corporate responsibility towards the environment and society out of conviction. In particular, the protection of our environment is important to us – it is a lived principle in the company. We see intelligent networking, artificial intelligence, Internet-of-Things, new materials and innovative machining processes as an opportunity and incentive to continuously optimise our products.

We actively engage in the qualification of our employees through training and further education. We achieve our result in a cooperation with customers, business partners and in our team that is characterised by honesty and fairness.

The indispensable basis for this is open and transparent communication, which we promote and demand.

HK-CON core competences

Design of mechanical parts, assemblies and systems, production planning, CAD, CAM


With the knowledge and experience of our design department, we create – from draft to detailed planning – technical drawings, models and manufacturing documents via SolidWorks. Diverse solution modules exist in the design of sheet metal and steel housings, the application of machine elements such as bearings and guides, the design of motor spindles and rotary unions, clamping elements, hydraulic and pneumatic components.

Production of automation systems, conveyor systems and handling systems (industrial robots, grippers, linear and rotary axes)

To reduce manufacturing costs by shortening production times, facilitating/eliminating human labour, ensuring quality, optimising resources and making processes more flexible, we equip our customers with automation systems.

Essential functions of these systems are: Selection, identification, positioning, gripping, transport, delivery and transfer to downstream systems, positioned storage.

We use the following function modules in these systems:

  • Roller, step and vibratory conveyors
  • Link belt and scraper belt conveyors
  • Pneumatic, hydraulic and electric gripper systems
  • Imaging evaluation systems
  • Testing and measuring systems
  • Linear axes via toothed rack, ball screw, linear motor, pneumatic cylinder
  • Industrial robots
  • Driverless transport systems

Application programming (controls, robot systems, test and measurement systems, MMI)

With the configuration and programming of the software systems used, we fully develop the performance of existing and newly created machines and plants.
In addition, data is generated from the sensors and actuators and transparently exchanged with or received from higher-level IT programmes, e.g. ERP systems, for further processing. Based on the networking, correct structure of the data, effective production planning, control and regulation is given via communication. The focus is on programming Siemens SIMATIC S7, CNC 840, HMI, industrial robots from ABB, Kuka, Stäubli, Yaskawa, Fanuc …

HK-CON Anwendungsprogrammierung

Design, planning and manufacture of electrical control, regulation and power circuits, manufacture of control cabinets

Our task is to connect various electrical components and communication elements, including sensors, actuators, motors, regulating, control and switching devices, machines and systems, measuring and testing systems.

The focal points of our connection are:

  • Air- and water-cooled asynchronous and synchronous drives
  • Servo drives up to 30 kW
  • Linear drives
  • Optical and inductive length measuring systems
  • rotary and position encoders
  • Quantity, temperature and pressure measuring systems
  • Operating and monitoring systems
  • Image processing
  • Programmable logic controllers

  • Power controllers and switches
HK-CON Schaltschrankbau

Design and manufacture of turnkey turning and machining centres

Our modular building block concept of machine bed, interlinked horizontal/vertical motor spindles, universal tool superstructures and tool storage units machines metallic workpieces in high-volume production. Accuracies down to 5 µm with the shortest cycle time in combination with investment costs are decisive criteria for our customers. Special solutions exist in the combination of turning and milling functions with fixed and/or driven tools, the arrangement of the axes in flatbed, column or portal design.

Machining of the workpiece is possible with up to 3 motor spindles/rotary tables in 3 set-ups on one bed. This enables simultaneous, independent machining of 3 workpieces. With the addition of synchronous spindles, 3 times 2 motor spindles are in use, a doubling of productivity is achieved.

Service on production, process and automation systems, retrofit

Malfunctions in the production process or quality defects lead to increased costs, accompanied by the loss of market shares and reputation. The analysis of malfunctions, the replacement and repair of defective electrical and mechanical components as well as the upgrading of equipment and control systems are part of our understanding of service. In addition, we support environmentally oriented approaches such as reuse of goods, reduction of resources and reduction of energy used.
