Plasma cutting head
On the gantry, the Plasma Cutting Head (High-Definition or Conventional Plasma Torch) is driven by 1 Y-axis motor with rack-and-pinion transmission and 2 oversized linear guides. The height movement of the torch is driven by a DC motor and ball screw. During the cutting process, the plasma arc voltage automatically takes control of this axis.
Control system: optimum operator convenience
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.
Hypertherm Plasma Sources
The HACO KOMPAKT can be delivered with various Hypertherm Plasma Sources, which are specifically designed to be mounted on X-Y cutting tables. It consists of a DC power supply, a gas console, the RHF console, the torch and all the cable and hose connections.
Ox Engineering supplies customised designed products to suit the different types of drill rigs used in exploration. Some examples are: dual rotary water well rigs, large oil and gas rigs, diamond drill rigs and reverse circulation. All of these drill rigs require different products for sampling, maintenance and safety; handrails, platforms for personnel and auto mobilising specialised equipment to take manual handling down to a minimum.
Demand in the industry is such that lead times were rapidly blowing out to three - four weeks, making business untenable for the Ox Engineering team. Given that the outlook for mining is relatively robust, Heath felt it was prudent to investigate the options to purchase a CNC plasma cutting machine to bring the plate cutting in-house.
Ox Engineering wanted a machine that could use their drawings with minimal fuss; it had to provide tight tolerances and accuracy, the cutting edge needed to be precise and the build quality of the machine needed to be high. And of course, meet our budget. As a result, Oxley chose a KOMPAKT 4020 CNC plasma cutting machine from HACO Australia.
“Previously, our lead times were too long; by the time the drawing was finalised and then outsourced for cutting we could potentially have lost 3-4 weeks. Now, with our own plasma cutter, once the drawing is complete, it can be cut in an hour. It has cut our turnaround time to a tenth of what it was,” says Oxley.
"The machine has only been with Ox Engineering for a short time, but has already made an appreciable difference to how the business operates. The company continues to grow both locally and into overseas mining markets, thanks in part to the introduction of a CNC plasma cutting machine to the company’s arsenal", Oxley concludes.
