CNC Spark Plasma Only 1.2 Metres x 2.4 Metres CNC1.2X2.4

DESCRIPTION

CNC SPARK PLASMA ONLY 1.2 METRES X 2.4 METRES CNC1.2X2.4

This CNC SPARK PLASMA Machine was designed and is made here in Australia, it does not mean that it should attract a hefty price tag like other Australian manufacturers insist. Through support of current and future customers, we believe we will enable Australian businesses to compete on the global stage.

This is just an overview of the base model of which I will explain into more detail further on in the description

Table or Knife Bed Configuration *
We provide a knife bed with 32mm x 3mm blades with a slotted 30×30 angle base for sizes up to a half sheet size. The blades are swappable, flappable and easily replaceable

Water Tray (Optional)
A water tray is ideal for clean cutting with a high smoke removal rate of about 60-70%. For 1×1 and 1.5×1, only one tray is needed. 1.5×1.5 combinations require 2 trays and 1.5×3.0 4 trays. The trays are 55mm high and require plumbing and joining with silicone and rivets/bolts. This reduces the shipping and handling cost significantly.

What can i cut ?
This machine is a very capable CNC that has proven to be able to handle most things we have thrown at it, but the limitation is the plasma cutter you choose. Just because you have a 100A plasma cutter, it generally doesn’t mean you should be cutting thin material on max. It is recommended that you turn the amps right down and aim to be cutting under 5,000mm/min.

The most common materials a plasma cutter can cut include:

Mild steel
Stainless steel
Aluminium (precautions for fumes must be considered)
Brass
…anything conductive

What plasma cutters have you used and can recommend?
The plasma cutter must be pilot arc start and not high frequency start.

What is good about This CNC Plasma Machine?
This CNC Plasma Machine has been designed to take your projects to another level with speed, ease and accuracy. By using rack and pinion and linear rails, it competes against the big players but at a fraction of the price.

You will find that the MyPlasm software has about 90% of the functionality of industrial controllers of which we feel that for most beginners this should not matter too much. Most notably is a missing nesting functionality which can be overcome by using either external software or separate nesting software. In saying this, you will find that many CNC packages do not offer nesting software without significant additional cost. Also, if you use a higher amp plasma cutter, you will find that you might not achieve a high resolution of cut when cutting thinner material at faster speeds. We know these are drawbacks but many current customers, this Spark Plasma seems to cater for most of their needs.

What power supply and air supply set up do I need?
From most of our testing, the limiting factor will be your plasma cutter and air supply.

Power supply considerations:
To achieve full use of your duty cycle, it is recommended that you ensure your breaker can safely handle the power requirements of your plasma cutter. For example, even though the Unimig Viper 30A has a 10A power supply plug, it will most likely trip your breaker before reaching duty cycle. It is therefore recommended that you engage an electrician to determine if you will need to upgrade GPOs and or breakers. Also, it is advised to operate the plasma on a separate breaker to all other appliances, especially the computer. If the computer loses power, you will not be able to resume your work easily.

Air supply considerations:
The next major consideration is a clean, regular and minimum air supply. It is recommended that you read the requirements of your plasma cutter and purchase/have a compressor that meets the minimum required, with some capacity to spare. A great and relatively cheap addition and a must to any CNC plasma cutter unit is a M-30 or AT1000 air filter or equivalent to ensure most of the moisture is collected. Even better is an air dryer.

What if I do not have the right plasma cutter, power supply or air supply?
The CNC Spark Plasma together with the right hardware and technique will produce a clean cut in any thickness. We stress this point because it is the number one question asked.

The issues that you might encounter if you do not have the right technique or hardware includes:

Poor cut quality – serrations, gagged edges, bevelled cuts etc
Dross – build up of slag at the top or bottom or your material due to feed being too fast/ slow, too close/far, worn consumables, incorrect air pressure or suboptimal plasma cutter.
Incomplete cutting – your material will cut most of the way but will miss certain spots due to dirty air, feed is too fast or amps are not high enough
Plasma cutter stops – this is where our plasma cutter turns off due to duty cycle reached or breaker tripped

What software is included or recommended?
With the MyPlasm controller, you will have access to MiniCAD and MyPlasm controllers. There are three elements to the workflow of CNC cutting include CAD – Computer Aided Design, CAM – Computer Aided Machining/Tool-pathing and Motion Control. MiniCAD together with MyPlasm does the CAD side alright, with limitations on anything outside of basic geometry. MyPlasm does the CAM very well with intuitive and seamless.  Just import your DXF file and let the software determine the cut path, lead in and lead outs. As long as your file is clean of double lines or incomplete shapes, MyPlasm will allocate the correct cutting path. Motion control is where MyPlasm shines with one of the best GUIs available in its class.

Some notable functions include:

Torch height control – adjusts cut height automatically via your compatible plasma cutter
Floating head – allows for initial height correction before cutting commences
Dual Y axis homing switches – corrects both left and right motors to ensure perfect X axis perpendicular
Easy DXF upload and toolpath generation – no need to assign lead in and lead out, cut in/outside
Restart from point or shape even after loss of communication or power
Graphical representation of the position of your torch
Live cutting and positioning on screen
Live voltage reading from your plasma cutter
Outer parameter framing
Soft and hard limits
Optional game controller control
Progress bar with skip to next or previous part
Save parameter function

What tolerances can I achieve?
Your Spark Plasma is “factory set” with nominal settings and will achieve accuracies 0.0-0.3mm. Albeit the remaining inaccuracy is due to the kerf of your plasma cutter consumables.
