Horizontal milling and boring machine

FCW 140, 150 and 160 – horizontal milling and boring machines, which are used in dusty working environments and when machining materials such as cast iron, special plastics or GFK.

Horizontal milling and boring machine FCW – Description of main groups of machine:

Bed

  • Grey cast iron structure – GG 30 (DIN)
  • Two guide ways
  • Hardened guiding ribs for X travel. Part of compact linear guiding
  • HEIDENHAIN linear scale for X-axis located on the bed
  • Hardened teeth rack for X – axis feed bolted to the bed section
  • Limit switches for X – axis
  • Telescopic protective steel-sheet covers over the whole width of the bed

Saddle

  • Grey cast iron structure – GG 30 (DIN)
  • On bottom side of saddle there are 5 roller (linear) tanks on each guide way for X travel. Part of compact linear guiding
  • Lubrication of tanks by means of grease
  • Backlash-free twin-pinion gearbox driven by SIEMENS AC drive for movement in X – axis
  • Hydraulically controlled clamping units in each corner of column saddle

Column

  • Grey cast iron structure – GG 30 (DIN)
  • Hardened guiding ribs for Y travel. Part of compact linear guiding
  • Counterweight for ram’s dropping compensation inside the column; including chain pulleys for hanging of headstock
  • HEIDENHAIN linear scale for Y-axis located on the column
  • Ball screw with rotating nut for movement in Y – axis
  • Limit switches for Y – axis
  • Telescopic protective steel-sheet covers over and below the headstock

Headstock

  • Grey cast iron structure – GG 25 (DIN)
  • On backside of headstock there are 2 roller (linear) tanks on each guide way for Y travel. Part of compact linear guiding
  • Lubrication of tanks by means of grease
  • Consists of basic parts like ram, boring & milling spindle, frames, gearing etc.
  • Gearbox for Y – axis movement driven by SIEMENS AC drive mounted on headstock
  • Three-step spindle drive with gears in continuous mesh and hydraulically shifted claw clutches
  • Thermal stabilization of oil fillings of the headstock and main drive gearbox
  • Disc brake of main drive is hydraulically released

Ram

  • Special cast iron GGG 60 (DIN)
  • Ram’s movement via ball screw and AC feed drive SIEMENS
  • Milling and boring spindle seated inside the ram
  • Compact roller guiding for ram’s out travel
  • Automatic clamping system of attachments onto ram’s face
  • Automatic ram’s dropping compensation system

Ram’s dropping compensation system

  • FCW machines use special SKODA automatic ram compensation system
  • Ram out-travel is compensated by hydraulic cylinder, which is attached on the front chain of the headstock by means is connected with counterweight.
  • Additional ram compensation system is working on a basis of supporting of ram from bottom by means of hydraulic cylinder.
  • Pressures in hydraulic cylinders for both compensation sub-systems are controlled by CNC system of the machine.
  • Automatic ram compensation is functional along whole out-travel of ram as well as when special milling and boring attachment loaded on the ram.

Boring spindle

  • Special nitrided forging alloy steel, hardness HV 850
  • Seated in milling spindle and ram. Seating of spindle in special ball bearings with oblique contact (maker SKF / FAG). Lubrication by means of oil mist
  • Spindle’s movement via ball screw and AC feed drive SIEMENS
  • Complete spindles’ seating dynamically balanced
  • Oriented stop of spindle, spindle’s rotary encoder
  • Mechanised tool clamping chuck collet as per DIN 69872  (hydraulically operated tool release, tool clamping by disk springs)

Operator’s platform and machine control

  • Semi-closed operator’s platform firmly bolted to the column saddle. In front part and from above is protected against flying chips and splashing coolant based on international safety standards.
  • Front part of the platform is moveable in ram’s direction (Z1) for 1 000 mm
  • Main operator’s panel located on rotary pillar on the operator’s platform.
  • Auxiliary portable panel with a cable with appr. 6 meters long for set-up and test purpose incl. position read-out

Hydraulic system and equipment

  • Circuit for lubrication of spindle’s seating
  • Circuit for thermal stabilisation of headstock and feed boxes with compressed cooler of used oil
  • Circuit for thermal stabilisation of ram by means of controlled heating
  • High-pressure circuit for auxiliary functions of machine like tool releasing, ram compensation, clamping units (X, Y), gear shifting, main disk brake, etc.
  • High pressure air distribution for tool hollow’s cleaning, spindle seating sealing, sealing of scales of measuring system, etc.

Standard accessories

  • Set of tools for maintenance (according to list in Operation manual)
  • Set of spare parts for 2 years trouble free run of machine (according to list in Operation manual)
  • 5 pieces of retention studs for clamping tools with tool taper ISO 50 (DIN 69871 – AD)
  • Checking fixture EMA
  • Anchoring material ŠKODA for machine (delivered without auxiliary materials for fixing like cement, grouting material etc.)
