1) Product Description – Hole drilling Machine
High speed pinhole processing machine mostly applies to process stainless steel, hardened steel, hard alloy, copper, aluminum and different kinds of conducting materials.It can directly penetrate or drill from cant, camber and pyramidal face. The machine applies to process unmanageable deep pinhole such as threading hole of wire cutting on ultra-hard conducting material, nozzle opening of oil pump, spinneret orifice of spinning die, oil way of hydropneumatic components and cooling hole of engine.
The operation of the machine is simple and convenient. The principal axis is driven by DC servo motor or step-by-step motor with the advantages of speed adjustable, stabiliby good and noise lower. When the worktable moves, the light grating shows. The work liquid can be running water or pure water. (distilled water or deionized water) with better results.
