CNC-Horizontal Boring and Milling Machine FPT CASTEL RED

CASTEL RED is a transverse travelling column boring machine with a table that can be moved in longitudinal direction.
The CASTEL RED offers, like all horizontal FPT machines, practical advantages such as:

• Maximum flexibility thanks to the wide range of available accessories
• Easier operator access to the working area
• Better chip disposal

Machine structure: stability and accuracy

• The structure of CASTEL is made of an electro-welded steel structure and integrates the upright and the cross slide in a single element. Between the four symmetrical vertical guideways, the spindle unit moves vertically.
• The column achieves the necessary rigidity to ensure accuracy and alignment and to prevent deformation during heavy roughing operations. The special symmetrical structure has a high vibration damping capacity and ensures high thermal stability.
• The column bed, which can be moved in a transverse direction, is made of an electro-welded steel structure. It is provided with hardened and ground guideways of large dimensions. The three guideways ensure high rigidity and accuracy.
• The longitudinally movable stator bed consists of an electro-welded steel construction. The feed is on two linear guides, which enable a prompt, dynamic response and ensure high positioning accuracy.
• The rotary slide table base is made of cast iron, computer designed, therefore optimally dimensioned and appropriately ribbed to ensure maximum rigidity.
• The structural dimensioning, positioning and the shape of the ribbing were determined by FEM calculations. All components were tested statically and dynamically according to the qualification plan.

All components are stabilized after rough machining to avoid internal tensions.

• The milling head is integrated into the structure of the vertical guideways to increase resistance to deflection.
• The table and machine anchoring has been designed to ensure perfect rigidity, accuracy and lasting stability of the machine geometry.

Guide ways:

• The guideways and the base surfaces of the stand, stand and table beds are hardened and ground. The slideways are dimensioned to achieve maximum stability and accuracy.
• The Y- and Z-axes are moved on preloaded roller slides, the X-axis is moved on linear guides and preloaded roller slides. This allows fast dynamic response and ensures high positioning accuracy.

Axis shifting:

• The machine axes are moved by means of ground and hardened precision ball screws with preloaded ball screw nuts to minimize play and to achieve low friction when positioning on all axes.
• The axis movement is by brushless AC drives.
• The standard axis designation is: X = longitudinal travel, Y = vertical travel, Z = transverse travel (column); W = drilling spindle

Weight balancing system:

• The hydraulic counterbalance system on the milling head reduces inertia effects to a minimum, resulting in good positioning accuracy and smooth contouring.

Milling head (spindle holder head):

• The head is made of stabilized Meehanite cast GB/300 and moves within the stand on 4 guideways. The adjustment system used provides accuracy and rigidity for any type of application.

Spindle motor:

• The AC Brushless SIEMENS spindle drive (55 kW) is continuously variable with a two-stage ZF gearbox

Spindle:

• ISO 50 BIG PLUS spindle mount with automatic tool clamping. The axis of the drilling spindle is 900 mm and the diameter is 150 mm. The surface is completely nitrided.
• The use of self-lubricating bushes (with oil backflow) and the forced circulation of the oil in the areas of high heat generation ensure maximum thermal stability.

Cooling and lubrication system:

• The cooling system cools the oil circulating around the spindle, the bearings and the gearbox for thermal stability of the head and spindle.
• This effective cooling system of the bearings allows 3000 rpm (option•PLC control of the drilling spindle temperature.
• PLC control of the drilling spindle temperature. This system allows better control of the powerful cooling system and compensation of thermal expansion.Coolant system for the tool.

Coolant system for the tool:

• Coolant system for the tool with 1,200 litre coolant tank, pump with 4 bar pressure, delivery rate 28 litres/min.

Steel telescopic covers:

• Steel telescopic covers for horizontal, transverse and vertical guideways to prevent water and chips from entering.
