GORATU MAQUINAS HERRAMIENTA,S.A.

GCM 4 / 5 / 6 / 8 / 10 4 JANUARY - 2011

2. BED-TABLE

§ The bed-table is made of pearlitic grey cast iron, quality EN-GJL-300 (UNE-EN 1561

standard) with hardness of 190 ÷ 220 HB, robustly reinforced with ribs at the bottom

every 500 mm and studied by finite elements. Stabilisation is performed after machining

thus avoiding that the stress during the first roughing process causes deformations.

§ The column slides on the bed-table, with 2 size 55 linear roller guide ways in front and 1

slide with 6 carriages with recirculation rolls (RUSV type) in the rear part. Column

displacement by means of double pinion rack system.

§ In the upper part of the table is provided with 7 T-slots of 22 mm; the central one serves

as a reference with 22 H7. Also in the front of the table there are 2 T-slots of 22 mm

§ In the bottom part of the base holes are located for machine anchoring to the floor, with

threaded supports for leveling.

3. REAR GUIDEWAY AND REAR SLIDE

§ The base of the rear guide way is ST-52 material, with thermal stabilization, reinforced

with ribs, and studied with finite elements. On this base ties a bolted steel way, which it

is hardened with a hardness of 60 HRC and ground, with rectangular section of

140x50mm. In the bottom part of the base are located the holes for machine anchoring

to the floor, with threaded supports for leveling.

§ Material of rear slide is made of pearlitic grey cast iron, quality EN-GJL-300 (UNE-EN

1561 standard), with a hardness of 190 ÷ 220 HB, with thermal stabilization, robustly

reinforced with ribs and subjected to finite elements.

§ On the rear slide are located 6 carriages with recirculation rolls for displacement.
