EasyFlipper

Flipping large or heavy sheet metal parts can be slow, awkward, and risky.

The Solution

The Teqram EasyFlipper changes that — delivering a faster, safer, and more efficient way to turn parts of any size during cutting, grinding, deburring, or inspection. Available in pneumatic and hydraulic models, the EasyFlipper handles parts up to 5,000 kg with ease. A simple two-button operation lets you flip even your heaviest workpieces in seconds, keeping your forklift or crane free for other jobs. With its modular design, the EasyFlipper can be tailored to your process — from small sheet parts to long or wide components.

Designed for safety and performance

Safety sensors and protective features ensure your operators stay safe while reducing product damage and rework. Robustly built from high-strength steel and equipped with premium components, the EasyFlipper is designed for years of reliable operation — saving time, improving workflow, and reducing handling risks on every shift.

MicroStep

Protube supply a wide range of advanced CNC machines and concepts equipped with plasma, laser, oxyfuel, waterjet and 3D mill technologies. Besides machine mechanics, we develop and supply advanced control systems for machine tools and CAM software with custom modules for various applications. In the field of plasma cutting, MicroStep counts among the world’s largest and most reputable manufacturers.

The bevelled facts

Up to 50% of parts produced in the CNC cutting industry worldwide need to have bevelled edges, yet few machines are installed with bevel stations. The reason may be the additional cost of this advanced equipment, but mainly it is a low awareness by decision makers in engineering companies of the possibilities, availability and reliability of contemporary bevelling tool stations. The benefits – greater precision, along with significant savings of production time and capacities – easily outweigh the higher initial investment. Moreover, in automated preparation of bevelled edges on 3D objects such as domes, pipes, rectangular or IPE profiles, the use of specialised tool stations on gantry-based machines amounts to significant financial benefits.

ACTG eliminates the necessity of mechanical adjustment of the bevel head and significantly reduces setup time of the machine from several hours to a couple of minutes.

Additional bevelling

ABP – Additional Bevelling Process– enables adding bevels to parts that have already been cut with a straight tool. ABP as a supplementary feature to DBP (Direct Bevelling Process) provides several add-ons:

  • it can add bevels to parts which were cut on an external machine
  • it can produce parts with bevels of greater thickness than allowed by the capacity of the machine (e.g. it can cut top-Y bevel by plasma on mild steel parts with thickness > 50 mm, or add bevels to parts with thickness of up to 300 mm using an oxyfuel rotator)
  • ABP can greatly minimize waste of material and save consumables

Compensation of longitudinal displacements – an optional function which ensures absolute accuracy of the cutting machine in the longitudinal direction.

ABC – Adaptive Bevel Compensation – is an advanced feature for compensation of beam deviations. ABC enables implementation of databases of compensation angles and other values for various cutting technologies (e.g. Hypertherm’s True Bevel™ technology).

Automated line for
production of steel
structure parts

Automated lines of the DS type are an effective means to achieve high productivity in flanged parts production. This is achieved mainly through automation of loading input material and automated removal of finished parts, thus greatly minimizing the time required for material handling. They also help reduce the number of workers needed for the operation of the machine.

Automated line for production of steel structure parts

Used by some of the world’s most prestigious manufacturers Nearly 2000 MicroStep machines operate throughout the world.

3D Profile Cutting &
Mechanised Welding Machines

We specialise in CNC-controlled 3D pipe profile cutting machines and automated welding equipment. These machines are available in the RB Compact, RB Classic, RB Heavy-Duty and PB Robo series. The machines of the RB Compact, RB Classic, RB Heavy-Duty series, essentially intended for round pipes, operate with macro-controlled software. This means that the machines can be quickly programmed online, offline or via CAD/CAM modules for the profiles to be cut with the aid of already available cutting macros. The machines of the PB Robo series, designed mainly for beams, have a freely programmable software architecture that facilitates the autonomous generation of the cutting profiles offline with the use of CAD/CAM modules. Plasma and oxy-fuel are available as cutting processes.

Client feedback

Thank you, it has not been an easy project to say the least. I think jig-less robotic welding of structural steel has to be one of the most challenging things to automate, but also very rewarding. Protube’s continued support is very much appreciated. -  Project Team Leader  -
I must say this gesture has been comforting and it is pleasing to see the support shown throughout this transaction. Very pleasing. I thank everyone involved. -  Operations Manager  -
