Service & support – holiday for your EDM

Service & support – holiday for your EDM

Your holiday is booked, and the sun, the beach and relaxation are within reach. Time at last to ­unwind. Experienced EDM specialists who don’t want to plunge straight back into stress on their return from their well-earned break spare their machines a thought before they leave. By running through this brief checklist, you can ensure your machine gets off to a trouble-free start after a shutdown.

Service & support – holiday for your EDM.

Service – ready to help you.

Before your holiday

• Check the batteries in the generator cabinet and axis amplifiers and order replacement batteries if necessary
• Before switching off/shutting down, run the high flushing for an hour
• Thoroughly clean the workspace
• Remove the diamond guides and clean
• Clean the conductance sensor and water level sensor (important: only use alcohol and a brush!)
• Check wear parts such as bearings and rollers, and order new ones if worn down
• Check and clean filters and filter mats and replace if necessary

After your holiday

• Install new batteries if necessary
  Switch on the machine
• Install cleaned diamond guides
• Fit wear parts
• Give the machine a high flushing for about 15 minutes
• Align the wire and run the “Taper Z program”
• Check wire threading
• Start machining a test workpiece

Avoidable overheating

Maintenance should always include regular air filter ­cleaning and replacement. Filters protect the electronics and cooler from unwanted contamination and ensure that the components always stay cool when the going gets hot. Original filters are precisely attuned to the needs of the machine and provide the necessary protection to keep the machine up and running. False economies by installing no-name filters have been known to cause cooler failure. Avoidable repair and downtime costs on the four-digit euro scale are the consequences.

Ordered by 3.30 pm – delivered the next day

When machines fail and replacement parts are needed for repairs, time is of the essence, because an unscheduled production stoppage means stress and expense. Mitsubishi Electric’s after-sales service provides express parts delivery. All parts orders received via the service hotline or by email by 3.30 pm are processed the same day and sent on their way. And, if desired, express-delivered the next day as well.

The service team

Martin Kuptz has been working for the ­service department for 18 years. As the Group Manager Wire-Cutting and Die-Sinking Machine Service, he is in charge of the assignments of ­technicians on site and for service hotline staff all over Europe. He is responsible for incoming orders and parts shipment, the organisation and planning of technician assignments and for the associated accounting. The service team supports customers locally with some 1,600 assignments. These are joined by some 20,000 inquiries by phone and email to the hotline, which are all handled by skilled staff. Via the hotline, Kuptz’s team can swiftly settle a good 85–90 % of all inquiries within an hour.

Maximum start-hole efficiency

With just a few mouse clicks, it is possible to generate the exact positions of the start holes from the wire-cutting program. The process offers a rapid, visual control of the positions and error-free transmission of all start-hole data. An additional postprocessor is not necessary for the start-hole drilling machine. This how it works:

1. Switch on the ­start-hole ­drilling ­machine
2. Select the “Program” menu
3. Select the ­submenu “Indicate Wire Cutting Contour”
4. The drilling ­positions and wire contour are indicated
5. Check the start holes
6. Start the program
