HORIZONTAL MACHINING CENTER MODEL FU
The horizontal machining center FU is specified especially for milling of complicated shapes in manufacture of moulds, press tools, dies or of workpieces having very complicated shapes and large dimensions.
The machine parameters enable the FU to machine a wide range of materials, including alloy steels and light metal alloys.
The machine has the modular design which enables a considerable variability of its composition. The machine consists of the fixed bed and the longitudinal slide, which moves together with the column on this bed in the longitudinal direction. The knee with cross guideways for headstock travel moves along the vertical column guideways. The machine has the headstock available which can be equipped with the mechanism for automatic clamping of exchangeable spindle heads or headstock with non-echangeable head.
The workpiece working area is performed according to the customer’s requirement by means of fixed clamping plates and rotary tables (and with movable slides) for a variety of applications.
In its basic configuration, the machine is determined to work in the working area with the parameters given by the set of the combination of ambient condition classes IE 33, according to ČSN EN 60721-3-3:1997, A2:1998; however, the air temperature must range from +15 °C to +35 °C and the air pressure must be more than 90 kPa.
To reach the optimum working accuracy, the following conditions must be kept during machine work:
- Ambient temperature within +17 °C up to +25 °C
- Change of ambient temperature during 24 hours less than 4 °C
- Ambient temperature change gradient less than 0,5 °C/hour
The machine is manufactured in standard or strengthened execution. The strengthened execution is used for enlarged strokes in vertical axis (Y ≥ 3500 mm) and cross axis (Z=2000 mm). The reason is to keep accuracy and machine rigidity with extended travels.
The bed is made as a casting of grey cast iron and it is fixed with the machine base by means of anchoraging scewse. The upper part is equipped with profile strips of linear bearing guideways, on which the longitudinal slide and the column are moving. The rack for the motion of the longitudinal slide is mounted next to the front strip of guideways. The distance between the strips of the linear guideways is 930 mm for standard execution and 1200 mm for strengthened execution.
