MicroStep’s automated cutting machines for 3D structural steel jobs
In addition to the normal flatbed machines, MicroStep offers an exceptional variety of solutions for 3D Cutting of rotary objects and structural steel sections of various shapes. The rotary objects include differently sized circular, square and rectangular hollow sections, conical pipes, tori-spherical or elliptical dished ends and elbows.
MicroStep’s machines standard setup for sheet and pipe cutting consist of a cutting table for sheets and a channel for pipe positioning that is placed along the longitudinal side of the table. The pipes are clamped in a rotary pipe cutting device located at the one end of the channel.
The cutting process involves a combination of movements: the gantry with tool stations – straight or bevel – and the pipe cutting device are synchronized for a precise positioning of the pipe towards the cutting tool.
Polygonal profiles or elbows can be attached with a clamp to the pipe cutting device. For cutting of dished ends, a dished ends cutting area can be located behind or in front of the cutting table. A single cutting tool is used to process all different shapes of material.
For applications in the structural steel industry MicroStep has developed a product line of specialized machines for cutting of structural steel as well as systems for automated cutting and drilling of flanged parts.
These machines can be supplied depending on types and sizes of processed material or the requirements for automated material input and/or part output. All of these systems can be connected to a production line in the customer´s facility.
For cutting of hollow structures of circular and rectangular cross-sections we supply cutting machines PipeCut and CPCut. Both systems are configured for the special requirements of the customer’s production. PipeCut machines can have a working length of 3 m, 6 m or 12 m and can process pipes with diameter ranges of Ø 50 mm up to Ø 800 mm. The maximum wall thickness is 50 mm for plasma cutting and up to 100 mm for oxyfuel.
The CPCut machines can also process large-sized pipes with diameters of up to Ø 3,000 mm.
For cutting of open sections, such as I, H, U or L profiles, MicroStep introduced a concept with a 3D kinematic system that is positions the cutting torch above the surface of a steady profile – this machine is the ProfileCut .
During the cutting process, the cut profile is motionless while a specialized 3D cutting head with tilting ability of 120° moves around the profile both in the longitudinal and transverse directions. The ProfileCut options can be enhanced by adding a drilling/tapping/countersinking tool station with automatic tool exchange for drilling of up to Ø 40 mm or by various marking tool stations. The precision of cutting and positioning of the tool above the actual profile is achieved by advanced 3D scanning of a profile shape with a laser line scanner. This is followed with the automatic adjustment of the cutting program as well as adjustment of machine movements according to the true shape of the material.
In addition to 3D Cutting of open profiles, ProfileCut machines can be equipped with other cutting options. e.g. for processing of hollow profiles (cutting by means of a pipe positioner like on a PipeCut machine) or a cutting table for sheet cutting like on a standard flat-bed machine. All of this made possible with the same gantry and tool stations. This is what makes the ProfileCut one of the most versatile cutting solutions for steel constructions on the market, and we are very proud of its capabilities.
For automation of the cutting process MicroStep offers enhanced versions of its machines for any application. We have our own specially developed software that makes this possible.
