Plasma cutting

The HACO PROXIMA base consists of IPE profiles (I-beams) over the entire length. The gantry of the machine rests on oversized linear guides, mounted on these IPE profiles, and is driven by brushless Servo motors with rack-and-pinion system on both sides (double X-axis drive).

The machine base is longer than the length of the cutting table, as to provide a free space at the back of the table to ‘park’ the gantry to avoid damage to the cutting head while loading and unloading material sheets.

The plasma cutting head and or oxy-fuel cutting head is mounted on a rest (carrier), which is attached to the gantry for movement in the Y-direction. The height of the cutting torch is controlled by a DC motor. During cutting with the plasma torch, the voltage of the plasma arc is measured and used to keep the torch at an equal distance from the sheet for optimum cutting results.

The cutting table of the PROXIMA is separated from the gantry and IPE Profiles. It consists of approx. 500 mm wide scrap bins with integrated fume extraction doors. These doors are opened automatically by pneumatic valves which are controlled by the position of the gantry. The selective opening of the doors thus guarantees very efficient fume extraction, an absolute requirement for plasma cutting applications.

A grid is put on top of the scrap bins, and on top of this grid is put the frame of the cutting table. The cutting surface itself is made of upright, slightly curved metal strips over the entire width of the machine. These metal strips can be cut on the machine itself for later replacement.

The HACO KOMPAKT can be delivered with various Hypertherm Plasma sources, which are specifically designed to be mounted on X-Y cutting tables.

The APC59-T Control is a graphical CNC Control System, with a 15” TFT touch screen mounted on a separate stand in front of the machine for optimum operator convenience. The touch panel effectively reduces the number of keyboard and button actions to an absolute minimum, allowing the user a straightforward, intuitive control of the entire production cycle. The highly advanced software raises the bar for other plasma software on the market. The simple layout of the user-interface allows direct access to the desired functions, thus creating optimum operator convenience. Depending on the specific production requirements, the appropriate cut chart, or technology table, can be chosen within seconds. The software automatically displays the correct consumables for an efficient plasma head setup. The software also keeps track of the lifecycle of the consumables letting the operator know when a certain consumable is nearing the end of its use. This way new consumables can be ordered in time.

Rotation of the cutting program is also possible, in case the sheet is too heavy to put parallel to the machine table.
