HARDENING MACHINES

Induction hardening. Customized. Precise

Induction hardening is a special form of heat treatment in which metallic workpieces are hardened by partial heating and subsequent quenching. The basic principle of induction hardening is based on the physical law of electromagnetic induction. The heat treatment process can be easily integrated into any production line. We have been successfully building induction hardening machines based on this principle since 1952, which are used reliably and flexibly by our customers worldwide and also in our Power Components and Industrial Components divisions. We offer the right hardening machines and hardening processes for almost all applications to suit your needs. Customer requests and special requirements are analyzed at the inquiry stage and implemented to maximum satisfaction. Customized machine developments, laboratory tests and test hardening on our own laboratory machines are further components of our product portfolio.

Hardening machine FAQs

Induction hardening

Service

We use a global network to service our machines. In addition to our service team at the Aalen site, we have set up various local service locations.

Space requirement

All our machine concepts are optimized for a minimal footprint. Please refer to our product flyers for exact dimensions.

Energy efficiency

In order to reduce the ecological footprint and TCO, all of our machines are developed and designed for optimized energy consumption. Among other things, we use frequency-controlled pumps and the latest generation of inverters for this purpose.

References / Experience

We have supplied over 560 crankshaft hardening machines worldwide to date. Based on our experience, we offer technology that exceeds your expectations. Expect a world-class hardening machine from us.

Delivery time

The delivery time for our machines is between 6 and 12 months, depending on the machine type and configuration.

Cycle time

The cycle time of our systems are adapted to the customer's requirements. Depending on the application, the machine set up and automation concept, cycle times of just a few seconds can be achieved.

Max. possible component measurements

Our crankshaft hardening machines are versatile and cover sizes from 250 mm to 4.5 m in length.
Depending on the machine type, our vertical and universal hardening machines cover sizes up to 1.5 m in length and up to 400 mm in diameter.

Inverter power / number of inverters / frequencies

The inverter power for our systems currently ranges from 60 kW to 400 kW and a frequency range of 2 kHz to 400 kHz. Special sizes and frequency ranges can also be implemented on request.
