HART-SM possesses the following machine park:

  • 5 tables for glass cutting in JUMBO format
  • 5 tables for glass cutting in half JUMBO format
  • 15 two-edge machines for grinding rectangles (C-edge, A-edge, polished)
  • 7 Devices for grinding and polishing shapeless glass pieces
  • 3 Devices for cutting out any shapes (WJS)(cutting using a high pressure water jet).
  • 25 Device for drilling holes in the glass
  • 20 Installation of complete screen printing
  • 11 hardening furnaces, enabling the production according to strict quality standards.
    They allow to temper flat and curved glass with a thickness of 2.85mm – 20 mm
  • 4 machining centres

The glass processed in HART-SM goes through several basic production processes:

  • cutting out of workpieces with rough dimensions from 1600-2000 to 3210×6000. The cutting out is performed automatically
    on four-numerically controlled tables.
  • grinding the edges. Depending on the model, this operation is performed on multi-spindle
    high-efficiency “doubleedgers” (rectangular panes) or on a single spindle
    numerically controlled – shapes with angles and other irregular ones.
  • drilling or cutting out holes. We use two methods. For standard
    (Round holes Ø <50 mm) we use bits of diamond drills, for large diameter cut-outs and holes
    non-round use of numerically controlled machine equipped with a stream of water – Water Jet.
  • We apply silk-screen graphic durable. Special paint is used for it, whose contents
    include the glass base (fine glass dust) and properly selected pigments. The composition of the dye causes
    that it blends and unites permanently with the form glass in the heating process.
  • We harden the glass to utilize the properties, which create the thermal shock in the glassglass structure.
    Panes are soaked long enough (depending on the thickness), until the temperature
    640 – 680 Celsius is reached. The glass is then subject to rapid cooling, which causes changes in the structure
    of the raw material, which allows you to get the appropriate characteristics of the finished product.
