Hoffmann Group presents Garant SG1 with active cooling system

The SG1 is a 'whole area' between devices of contraction. As in the case of hard metal, HSS or steel tools, high-performance of the SG1 Garant electronics allows contraction in matter of seconds. During the process, changes of coil in the range of diameters of the tool are not required. In addition, the contraction range covers a diameter between 3 and 32 mm (MD / HSS). The Induction coil of high power, with a capacity of up 41st with 1,000 V of tension, produces rapidly alternating eddy currents that have a direct effect on the cones of subject and generate heat at the exact point in which the cutting tool is located. In this way, the SG1 produces high density of energy with a low energy intake. At the same time, only a small portion of the energy is stored in the cone of subject. In combination with contact coolers manually guided, unselfish heat dissipates quickly and the cooling is accelerating. Four plates of quick-change facilitate controlled protection of the magnetic field between the coil and handle of the tool. There are two of change special plates available as accessories for the cone of contraction Garant Shrink Collet (Cone SC). Using the SC cones, all mango to H9 tolerances can be contracted or loosen easily. The application of energy-efficient, as well as a safe and rapid cooling process offer an important customer benefit, because this guarantees that the tool may become to use quickly. This saves time and money.

Following the principle 'form-follows-function', SG1 combines design Garant tried and tested, high functionality and the best specifications. The work surface is made of a robust and resistant to temperature. Practical seats for boards of rapid change and cooling adapters are on the rear wall. In this way, the parties are stored easily and are accessible at all times. The possibility of damage to the tool is removed by cooling with guided forced bells: the change of the adapter of cooling is carried out quickly and easily. Cooling adapters are available for all sizes.

In addition, to operate this device of contraction does not require training: the SG1 can be operated intuitively. This means that the language spoken by the operator is irrelevant. The operation is simple, safe and independent of the language. It is not necessary that the operator specified personally the heating of the Induction coil and the performance time. Adjustments are calculated automatically by the SG1. The only thing that must pre-qualify is the type of the cone of contraction and the diameter of the handle of the tool. In this way not you can overheat. Existing tools can move easily to the position of cooling. After a brief period of cooling, the tools are ready for use; It's as simple to loosen the tools like contracting them. After that, the cone of subject can be again equipped immediately.

Extensive equipment

The SG1 measured 800 mm long x 540 of high bandwidth 802 x, has a weight of around 80 kilos, and it can achieve a power of 11 kW. The extensive standard equipment includes the basic unit of contraction, the active cooler, a shell of accommodation, four plates of rapid change, a tray for tools and a series of inserts of cooling.

As special accessories are available flanges additional mounting, bushings of accommodation and inserts cooling spare. Flanges for mounting of variable applications for different wavelengths of cones tools make the SG1 suitable for different types and sizes of tools. Additional spraying SKE1 cooling unit can be easily coupled to the SG1. The SKE1 provides a cooling independent of the outline for cones of contraction with lengths of up to 400 mm. The cooling time is only 30 seconds. In addition, is also available on request a wardrobe Assistant frame Garant where refrigerators assets or more tools can be stored.
