MTE FBF 8000-X

The FBF Floor Milling Center has been developed through Finite Element Analysis and the moving parts have been calculated through Dynamic Load Calculation. Bed, Column, Saddle and Ram These components are constructed in GG-30 Cast Iron material with a hardness of 220 Brinnel. The right size and the internal ribs of each part guarantee the rigidity of the machine. The bed is a rigid, cast iron structure that supports the saddle on two guideways that are spread 1435 mm (56.5”) apart to provide a stable base. The column is a heavily ribbed, cast iron component with a cross section of 1200 mm (47”) x 1300 mm (51”). It uses two guide rails spread 900 mm (35.4”) apart with size 100 roller guides to precisely move the vertical saddle and RAM. The cast iron vertical saddle uses 1110 mm (43.7”) of the two vertical guideways to provide rigid alignment of the RAM to the column. The 1550 mm (61”) of RAM support allows long reach with plenty of rigidity. The Ram is made of GJS-600 Cast Iron with a high module of elasticity that increases its rigidity. The massive 510 mm cross section quietly delivers full spindle power while fully extended. All components are stress relieved via a stabilizing heat treatment. Guide ways All 3 axes are equipped with hardened and ground carburized Chromium-Nickel steel roller guides with a hardness of 60 Rockwell C. On these roller guides slide the preloaded roller packs or “trucks”. In the vertical traverse (4) roller packs of size 100 with 330,000 lbs each of static carrying capacity are used. In the cross traverse (8) roller packs of size 65 with 120,000 lbs each of static carrying capacity. In the longitudinal traverse (8) roller packs of size 100 with 330,000 lbs each of static carrying capacity. In the Ram (Y axis) keyways with Turcite, perfectly adjusted to the roller guides, are fitted between the roller packs. By this method, rigidity of the system is increased.
