1. Major components – manufacturing and material:

Double column hosing – Consists of both left and right side column and beam between columns,beam and columns  are firmly connected by bolts.

  • Columns:

Weldment of steel plate (JIS SS400, annealing of welding stress) Box shape construction

  • Beam:

Same as columns

  • Bed: Weldment of steel plate (JIS SS400, annealing of welding stress)

3-pieces construction

  • Table:

Castings – 1 piece construction (JIS FC300, annealing of casting stress) Take Box shape section and radial ribs are arranged from table center

  • Cross slide:

Body portion – Weldment of steel plate (JIS SS400, annealing of welding stress) Box shape construction

Saddle guide rail portion – Castings (JIS FC300, annealing of casting stress)

  • Saddle: Castings (JIS FC300, annealing of casting stress)
  • Ram: Weldment of steel plate (JIS SS400, annealing of welding stress)

2. Table:

  • Hi-rigidity, Hi-precision – Center: double row roller bearing, single thrust ball bearing Peripheral: Thrust roller bearings are used.
  • Powerful, Smooth drive – AC 100kw x 2 units motor with 2 range gear drive. All drive gears are heat treated and ground finish.

3. Ram and Ram head:

Ram takes 500mm dimension of section and 4-faces of ram are guided by Tercite B coated face with precision scarping, therefore hi-rigidity and precise movement is assured. Ram head takes linear bearings between upper face of cross slide guide face and contacts to front and therefore hi-rigidity and precision is achieved.

4. Cross rail:

Cross rail takes enough dimension of contact face to columns (width of height and depth of from-gear direction), therefore hi-rigidity and stability is assured. Compensating function of deflection for span: Wedge blocks are mounted by equal distance space between cross rail body portion (Weldment of steel plate) and saddle guide rail portion (Castings).
