Hardening and tempering - Import export

The AL-ROCK is a laser hardening system for surface hardening with a self-propelled caterpillar track. The laser can be brought directly to the workpiece. Time-consuming removal of the components to be hardened can often be avoided. The robot arm easily reaches the hard-to-reach places on the workpiece. All common metals can be hardened, e.g. Quenched and tempered steels, cold work steels and cast steel or gray cast iron. The material must have at least 80% pearlite. The degrees of hardness that can be achieved are identical to those of conventional hardening processes. In free 3D movements, the laser beam precisely follows even the most demanding three-dimensional workpiece contours, for example on tracks along closing edges. Pimples, scar structures. Simple points are also not a problem. Only the free access of the laser beam to the surface to be hardened is required. And the AL-ROCK can do even more - on request, the laser robot can also be used for laser welding.

ELITE roller chains with sawtooth plates are extremely wearresistant and designed for optimum fatigue strength. They are used mainly in the wood processing industry for transporting raw timber and sawn planks. ELITE highlights: • Our chains are based on the minimum requirements set out in standard ISO 606. • The steel alloys used are case-hardened and tempered. • Heat treatment of all chain parts is optimized to suit size and application • All roller chains are prestretched to >40% of breaking load as standard • The high quality assurance standard fulfils the requirements of ISO 9001 • Plates 1 are shot-blasted for maximum fatigue strength • Seamless, cold-extruded, shot-blasted rollers 2 with extremely regular wall thickness • ELITE pins 3 are smooth and have an extra hard surface for increased wear resistance

The ETx25 singleturn Hall effect encoder family is characterized by its high durability with over 100 million shaft revolutions and independent linearity up to +/- 0.3%. The rotary encoders measure angles contactless with a hardened and tempered sleeve bearing made of metal. The sensor technology offers a 10 times longer lifetime expectancy than conventional potentiometers. The sensor in the Ø25 mm housing with Ø6 mm or 6.35 mm (1/4 ") shaft diameter is fixed in the application by means of a central thread. It can be chosen between following electronics: Absolute encoder: — Single- or multiturn — Analogue: Voltage/current output, PWM - 12 bit — Digital: SSI, SSI+UVW up to 16 pole pairs, SER, SPI - up to 14 bit — Also redundant Incremental encoder: — A, B, Z also differential A, A/, B, B/, Z, Z/ — OC, TTL, PP signal outputs — Free selection of the number of pulses - up to 1024 ppr. — UVW signals for motor commutation of DC motors up to 16 pole pairs

ETx25F encoders are used for reliable angle measurement with a hardened and tempered sleeve bearing made of metal: as singleturn variant (360°) with analogue, PWM, incremental, SER or SPI output or as multiturn variant (up to 72000°) with analogue output. ETx25F can be used up to medium environmental requirements (from shaft side max. IP55M/IP66S). Singleturn electronics: ETA25F absolute encoder (ETA25F X redundant version): Provides an absolute analogue signal with 12 bit resolution. ETP25F absolute analogue encoder: PWM output. ETI25F incremental encoder: With up to 1024 pulses / per revolution and availability of following output signals: TTL, Push-Pull or Open Collector. ETS25F absolute encoder with digital output: 12 bits resolution with SER interface and in 14 bits resolution with SPI interface. Multiturn electronics: ETP25F PM multiturn encoder with analogue output, direct programmable on site: The ETA25F PM measures angles from 0…10° up to 0...72000° (absolute).
