Mechanical engineering production - Our technologies

Our technologies:

The machinery plant incorporates independent units (production workshops) that are capable to produce some types of machinery goods with a minimum of between-shops cooperation, to make the surface finish of the goods and in a final phase to assemble them into units and dispatch them.

Machinery equipment:

• The locksmith’s workshops
  • Sheet products - coverings, consoles, lids, apparatus cases, panel covers, electro-panels.
    Technology - shearing, drilling, welding, finish. The parts are produced with a tolerance common for such products
  • Structure products - foundation frames, dryer’s frames, piping’s, steel structures.
    Technology - burning, welding, drilling, finish. The tolerance in the production common for these products
   
• Case parts
  • Products of cast iron and cast steel - side frames, frames, gear boxes, levers.
    Technology - drilling, sheets, machining, precise openings machining, threading etc. Production tolerances IT6.
  • Structure steels products - levers, tanks, beams, hydraulic blocks.
    Technologies - welding, burning, straightening of plane surfaces and grinding, holes drilling, threading.
    IT6 production tolerances.
   
• Cylindrical parts production
  • Shaft parts, shafts, knife rolls, aluminium shafts, hammer wrought rolls.
    Technologies - lathe - turning, drilling, threading, groove milling, balancing, and grindings. IT6 production tolerances.
  • Flange parts, belt pulleys, flywheels, pistons, hydraulic cylinders, covers, connecting rods, sleeves
    Technologies - lathe - turning, milling, drilling, grinding, oil grooves making. IT6 production tolerances.
   
• Small parts production
  • Caps, levers, journals, sleeves, screws, nuts, block, hydraulic elements, pistons, shafts, belt pulleys, flywheel.
    Technologies - milling, lathe-turning, grinding, drilling, cutting rolling, mechanical work (packing production).
    IT6 production tolerances.
   
• Gear wheels production
  • Spur gear, helical gear - module 2,5 - 16
  • Cone gear - module max. 6
  • Spiral gear - module 1,5 - 10
  • gear grinding - module max. 8, max. wheel width 150 mm. ( We have not equipment for internal gear)
  • band-wheel for gear belts HTD, pitch 8 and 14
   
• Material parting
  • Cutting of various shapes - circular, square, rectangular, hexagonal, rolled shapes in various lengths
  • Shearing - up to the material thickness of 12 mm
  • Direct and shape burning CNC, max. burned dimension 2000x6000 mm, thickness up to 130 mm
   
• Assemblies and electro-assemblies
  • It is possible to assemble all the leather machinery including electro-parts up to the mass of 12000 kg
  • It is also possible to assemble from delivered parts
   
• Surface finishes

  • Primer - by spraying, with a brush
  • Upper coating by spraying, with a brush
  • Cementing up to 3 times
  • Final machine finishes
    - epoxide and polyurethane coating system and polyurethane - wet environment
    - coating system by synthetic paints
   
• Kinds of treated materials
  • Structure steels in common qualities
  • Structure steels of the class 12, 14
  • Austenitic steels of the type 17027, 17246, 17347, 17348
  • Grey cast iron 422420, 422425
  • Cast steel 422650
  • Aluminium and bronze casts
  • Aluminium and copper alloys
  • Non-metal materials (rubber, nylon, teflon, glass, textile, pertinax, paper)
   

Required quality of products:

• All parts are produced in a quality prescribed in production documentation.
• Surface treatment is made within the limits Fa 0,8 m - 100 m in accordance with the products character.
• Dimension accuracy of parts is within a tolerance of IT 6 - IT 12.
