The heavy plate after containing alkoxy silane derivatives and / or condensate solution dipping processing of the substrate, heat-curing resin impregnated non-halogen flame retardant, heat dried prepregs this pre-plate of a variety of machine tools, heavy machine platen, and a variety of machining tools. All clips are 45 # carbon steel as a whole is forged. Through a special heat treatment processing. The use of parallel plate and Note parallel plate'' the use of parallel plate and precautions 
 Milling on a common method using a parallel plate workpiece clamping, especially in a horizontal milling, end milling cutter with the most. Parallel plate installation workpiece in the milling machine, the machine tools is relatively simple, the main machine platen''> machine platen, Horn, T-bolt (or nut) and nuts, in order to meet the installation of different shape of the workpiece needs, the shape of the plate made of a variety of. Using the plate should pay attention to: 
 (1) the location of the plate to arrange appropriate pressure in the workpiece rigidity of the best machining center place, the size of the clamping force should also be appropriate, or the poor rigidity of the workpiece is easy to produce deformation. 
 (2) bed horn must be properly placed under the plate height of the workpiece is the same or slightly higher than the workpiece, otherwise it will reduce the compression effect. 
 (3) plate bolts must be machine as close as possible to the workpiece, and bolts to the workpiece, the distance should be less than the bolt to the distance of the horn, so you can increase the clamping force. 
 (4) bolts to tighten, otherwise they will be pressure processing center enough leaving the workpiece move, resulting in damage to the workpiece, machine tool and cutting tool. 


 Baptist billet slices overlap, have unilateral or bilateral stacked copper foil, heat and pressure cascade system.
