Milling of rolled steel profiles

Type of machine: HSC

Quadruple pick-up station enables the different milling cutter combinations
to be changed automatically

The tools, milling cutters equipped with disc cutter combinations, are housed in the spindle using an SK 60 cone, and stabilised by means of a
counter bearing

The clamping elements each open and pivot sideways to uncover the area to be machined for the milling tool as it moves past.

For heavy-duty machining of rail and strip profiles a high-torque 3200 Nm horizontal spindle and SK 60 toll holder are used

Task:

Milling of rolled steel profiles up to 8.8 m in length (lift masts for forklifts and high rack warehouses)

Solution:

Standard travelling column machining centre with horizontal SK 60 spindle
Four tools in a pick-up magazine, consisting of an SK 60 milling cutter with counter bearing, each fitted with
4 disc cutters of D = 500 mm
Hydraulic workpiece clamping device

Special characteristics:

Prepared for unmanned operation with automated loading and unloading
Identification of the raw workpieces lying on the conveyor belt by means of a camera system
Prefabricated parts are inserted into the clamping device and removed by means of a gantry loader
Automated clamping device for optimal workpiece clamping
High-performance chip extractor running in parallel on the X axis

Traverse ranges:

X-traverse range: 12000 mm
Y-traverse range: 600 mm
Z-traverse range: 525 mm

Spindle:

Main spindle drive (with 100% DC): 66 kW
Torque (with 40% DC): 3200 Nm
Speed range: 10 - 500 1/min

Tool changing system:

4 tool places SK 60
