If you want your plasma cutting machine to continue to perform at its best, you need to make sure that it is well maintained. From cleaning the torch body to checking the water quality to adjusting the gears and bearings, keep reading to find out everything you should be doing to prolong the life of your CNC plasma cutters and reduce the likelihood of it breaking down.

Clean the torch body

You need to make sure that you remove all the torch parts and examine the inside of the torch to ensure that there is no damage. You should also clean the inside of the torch using an electrical contact cleaner and a cotton swab and blow out any accumulated metal dust.

Clean the power supply

Metal dust can accumulate in the power supply of profile cutting machines which can lead to damaged components, particularly PC boards, so you must take the time to blow out any metal dust. You should also check the air filters and replace, if needed.

Clean the torch leads

Again, metal dust and dirt can accumulate in a torch lead, so you need to make sure you clean these thoroughly. Also, check for kinked or worn down hoses, exposed wires and cracked fittings.

Check the torch-cooling components

For water-cooled torches, you need to check the coolant stream for signs of aspirated air or reduced coolant flow. Also, check the coolant filters and pump screens and clean or replace, when necessary.

Check the water quality

Hard water can cause a whole host of problems, including reducing the lifespan of CNC plasma cutters and increasing the need for spare parts. You can use a commercial water softener if the water hardness exceeds 8.5ppm or 0.5 grains.

Check the plasma gas

If you want to continue to enjoy a clean cut and a fast cutting speed, you need to make sure that you regularly check your machine’s gas quality. You can do this by holding a clean towel under the torch whilst purging air through the system in test mode. You should also check for water, oil, mist, and particle contamination.

Clean all the components

You should clean all the machine components such as the rails, gears and racks using a degreasing agent and an abrasive pad. You should lubricate both the gears and racks but not the rails, as this can attract contaminants that cause excessive wear.

Align and adjust gears and bearings

The gears on your plasma cutting machine should not overlap above or below the rack. If they do, you need to adjust them accordingly. You also need to make these adjustments for rail and cross drives.

For manufacturers looking for a cost-effective CNC plasma cutting table that is easy to install, easy to set up and even easier to operate, Kerf Developments has the solution with the new Linc-Cut S 1530W. If you are looking to boost your responsiveness and creativity, this new ‘plug and play’ plasma cutting system could be the perfect cutting machine for your business.

The machine has been designed and developed by Lincoln Electric, the leading Global supplier of cutting and welding equipment.  Kerf Developments will be supplying and commissioning the machines and providing training for the operators, together with service, support and spares from their headquarters in Rochdale.

Perfect for cutting mild steel and stainless steel plate up to 1.5m by 3m, the Linc-Cut 1530 makes high-speed plasma cutting affordable and attainable for small metal fabrication companies, sheet-metal contractors, custom vehicle fabricators, and prototyping companies.  Whilst the cost-effective price point and flexibility of the machine make it appealing; the productivity, capability and flexibility guarantee a shrewd investment for any sheet metal processing business.

Parts that customers may want to manufacture on the machine can be input using a variety of methods. The CAD software supplied as part of the turnkey package enables users to draw components. The system also allows users to import parts in standard file formats such as DXF or DWG. Pre-loaded into the software is also 36 standard parametric shapes that include everything from simple adjustable rectangles through to complex circular flanges to simplify and speed up part programming for the end-user. Once drawn, the system is able to nest components with the potential for manual or automated programming for maximum material utilisation and cost-savings.

The Linc-Cut 1530 is fitted with the latest Lincoln Electric Flexcut 125amp plasma system which offers excellent cutting and marking performance with a very low bevel angle and an impressive cut quality. Adding to the quality and precision is impressive productivity levels with the machine capable of cutting 25mm steel plate at up to 800mm/min and thin sheets in the 6mm range at speeds beyond 5300mm/min.

From an ease-of-use perspective, the Accumove CNC motion control technology provides increased processing power and synchronisation of each component on the table. The electronic torch height control, motors and computer-aided manufacturing software are all managed within this single operating system that keeps the entire communication loop enclosed and delivered through a single visual display. The new Visual Machine Designer (VMD) is the human-machine interface (HMI) of all Accumove CNC controllers as its user-friendly design and appealing layout is extremely easy to learn and use. This is credit to a set of new functions that have been installed directly in the controller to simplify the cutting process.

These features include Process Management that allows all parameters to be controlled through the 20inch touchscreen display with a host of functions that can increase productivity. This intelligent system can automatically determine cutting conditions based on a few simple parameters entered by the user such as material thickness and type. Additional innovations include plate alignment that simplifies material loading and calculates alignment to adjust and control trajectory accordingly and the laser positioning mode that simplifies the aligning of sheets. The package also includes an automatic nesting module that enables users to load DXF or DWG files, enter the quantity and the VMD software will automatically generate the production nests.

Suitable for installation in any environment, the water table makes it possible to capture any dust released during cutting and any residual gas escape will remain below the exposure limit values for workshop conditions.
