GF-250

Product catalog summary

Introduction
The document introduces the GF series icing plates, a clamping system leveraging the adhesive properties of ice. This system is designed to securely hold delicate parts without causing stress or damage, making it ideal for industries such as space, medical, electronics, watchmaking, and jewelry.

Specifications
The GF icing plates utilize a compressed-air heat exchanger for cooling, with some models featuring a pneumatic control system to optimize air consumption. The tensile strength of ice is highlighted as superior to other methods like magnetization and vacuum.

Operation Procedure
To use the icing plates, connect to a compressed air system, spray water on the plate, position the part, and activate the temperature control. The water freezes quickly, clamping the part securely. Unclamping is achieved by reversing the freeze/thaw valve. The system ensures z-axis repeatability and eliminates the need for standard lubrication.

Applications and Benefits
The icing plates are suitable for milling, grinding, and diamond dressing operations. They improve the rigidity of materials like plastics and ceramics, enhancing surface conditions. The system's design allows for quick installation and operation, reducing the risk of distortion and breakage.

Optional Equipment
Optional equipment for the GF-250 model includes spindles for positioning, a non-freeze key for reference, and steel shims for securing on a grinder magnetic plate. The plates come with a carrying case, filter, wetting agent, airblast sprayer, and pipette.

Technical Data
The GF-250 model has specific dimensions and air consumption rates, ensuring efficient operation with dry, clean compressed air as per AFNOR E 51.301 standards.

This excellent adhesive1 can link practically any material, whether rigid (metal, plastic, ceramic, graphite...) or flexible (rubber, neoprene, cloth...). It has the additional advantage, when it melts, of being reversible and leaving no residues. Using these properties we have designed and developed a highly effective clam-ping system: GF sͩries icing plates. No more costly, specific assemblies. No more distortion and breakage due to clamping or unclamping... Whatever their shape, fragile parts are held firmly in place and without stress! Plate cooling is achieved by means of a compressed-air heat exchanger2.On some of our plates, the assembly is driven by a pneumatic control system2. By utilizing the thermal inertia of the icing plate, this control system also saves compressed air. For long machining cycles the air consumption time is half the operating time. Originally designed to meet the exacting demands in the space industry, the icing plates have since become a necessity in all fields involving the manufacture of delicate parts (medical, electronics, watchmaking, jewelry...). CAD UTILISATION The compact and monoblock, GF icing plates can be quickly installed: Connect the apparatus to the compressed air system3,spray water onto the icing plate and position the part to be machined. Then actuate the temp control button. Within seconds the water freezes and the part is clamped. Unclamping is done just as fast by reversing the freeze/thaw valve. As there is no water thickness un-der the part, z-axis repeatability deͭpends only on the referential. Because the plate evacuates the calories generated by machining, standard lubrication is no longer necessary. Freezing increases the ridigity of a number of materials (plastics, raw cera-mics, neoprene,...) thus improving surface condition. (1) Tensile strength : ice = 214 Ibs./sq. in.
