Which Die-sinking EDM Machine Manufacturer Offers Reliable AfterSales Service? Evaluating Installation, Training, and Response Speed

There is an old saying in the equipment procurement circle: “You buy a machine for its brand, but you use it for its after-sales service.” Die-sinking EDM machines are precision processing equipment, and during long-term operation you will inevitably encounter needs for commissioning, maintenance, and troubleshooting. At such times, the manufacturer‘s after-sales service capability directly determines how long your production line will be down and how much loss you will suffer.

So what exactly constitutes “reliable” after-sales service? What aspects should you pay attention to before purchasing? This article establishes an evaluation standard from four dimensions – installation and commissioning, operation training, response speed, and spare parts support – and uses Beijing NOVICK as an example to introduce the characteristics of its service system.

I. Installation and Commissioning: Done Right the First Time to Reduce Future Hidden Problems

The initial installation and commissioning after the equipment arrives on site directly affect operational stability for years to come. A reliable manufacturer will:

·Provide on-site service by professional engineers: After the machine is in place, engineers come to complete leveling, electrical connections, and system integration testing, ensuring the equipment enters a stable state as soon as it is powered on.

·Perform environmental suitability checks: Inspect workshop temperature, humidity, power supply, grounding, etc., to ensure they meet requirements, preventing accuracy drift caused by environmental issues.

·Conduct a trial cut for verification: After installation, machine a standard test piece or a workpiece provided by the user to verify that accuracy and surface quality meet the required standards.

NOVICK‘s installation service: The AF Series features an integrated structure combining the main unit, tank, and electrical cabinet, making installation and commissioning relatively straightforward. After the engineer arrives on site, all commissioning work is carried out according to standard procedures, and the machining results are jointly confirmed with the user. Remote technical support is also provided, so problems encountered during subsequent use can be diagnosed at any time via network connection.

II. Operation Training: Ensure Operators Truly “Know How to Use and Maintain”

No matter how good the machine is, improper operation can ruin it. A reliable manufacturer provides systematic training, not just a formality.

A complete training program should at least cover:

·System operation: Interface logic, parameter setting, programming methods, use of orbiting functions, etc.

·Machining technology: Selection of discharge parameters for different materials (steel, copper, cemented carbide, titanium alloy), techniques for controlling electrode wear.

·Daily maintenance: Dielectric fluid management, filter cartridge replacement, guide rail lubrication, accuracy inspection, etc.

·Safety regulations: Discharge safety, fire prevention, fluid temperature monitoring, emergency stop, etc.

NOVICK‘s training system: The AF Series is based on the Windows operating system, with an intuitive interface, touch screen, and pendant control box, resulting in a low operational learning curve. The manufacturer provides onsite training until operators can independently complete programming, machining, and daily maintenance for typical workpieces. Training includes how to use the expert process parameter library – users do not need to memorize complex parameters; they simply select the material and machining requirements, and the system automatically matches the optimal conditions. This greatly shortens the learning time for beginners.

III. Response Speed: Downtime Equals Loss

For production enterprises, unexpected machine downtime means order delays and customer loss. Therefore, after-sales response speed is a hard metric for evaluating manufacturers.

A reliable after-sales system should have the following capabilities:

·Remote diagnostics: Most software-related or parameter-related problems can be resolved remotely over the network without waiting for an engineer to arrive on site.

·24hour service hotline: Technical support is available whenever an abnormality occurs.

·Rapid on-site response: If a problem cannot be resolved remotely, an engineer should depart as soon as possible, carrying necessary spare parts to the site.

·Service network coverage: The manufacturer has service centers in major industrial cities nationwide, shortening geographical distances.

NOVICK‘s service network: The company has an R&D center in Beijing and a production base in Langfang, with multiple sales and service locations across the country. The after-sales hotline provides 24hour technical support; common faults can be diagnosed remotely. When on-site service is truly required, engineers are dispatched as quickly as possible with necessary spare parts. For most small and medium-sized enterprises, this kind of “localized service” is far more practical than the weeks-long wait for spare parts often associated with imported brands.

IV. Spare Parts Support: Transparent Pricing and Timely Supply

Consumable parts for die-sinking EDM machines include filter cartridges, seals, lubricating grease, etc. If the supply of these parts is not timely or prices are not transparent, they become an additional burden on the user.

When selecting equipment, you should ask:

·A list of wear parts and recommended replacement intervals (e.g., filter cartridges, seals for the AF Series).

·Whether spare parts prices are publicly disclosed and stable.

·Whether common spare parts are in stock and can be delivered next day by courier.

NOVICK‘s spare parts policy: The product technical information clearly lists the part numbers, specifications, and applicable models (e.g., AF50/AF70 filter cartridges, seals). Users can order directly through service channels, with transparent pricing and relatively short delivery lead times.

V. Extended Services: Relocation, Upgrades, and Regular Maintenance

Beyond failure repairs, good manufacturers also offer proactive maintenance and services that grow with your business:

·Regular inspections: Proactively visit on site to check the equipment‘s condition and identify potential problems early.

·Equipment relocation: When a business expands or moves, provide professional disassembly, reassembly, and re-commissioning services.

·System upgrades: As technology evolves, offer upgrades to the operating system or process database.

NOVICK’s extended service capabilities: As an enterprise with many years of deep experience in the EDM field, NOVICK has accumulated expertise across a full product line – from brass wire cut and molybdenum wire cut to die-sinking EDM. Its service team provides full-lifecycle support to users, from selection consulting, installation and commissioning, operation training, to relocation and upgrades.

VI. Three “Must-Ask” Questions Before Purchase
Before signing the contract, it is recommended that you clarify the following with the manufacturer:

1.How long is the warranty period? What does the warranty cover? Does it include labor and travel expenses?

2.Are there service locations in your local area? What is the average on-site response time?

3.Is training provided free of charge? Will it continue until the operator can work independently?

VII. Conclusion
The after-sales service for a die-sinking EDM machine is not a “free gift” when purchasing the equipment; it is an “insurance policy” for long-term use. A machine may be used for ten years. During that time, whether the manufacturer can respond promptly, solve problems professionally, and provide adequate support directly determines your total cost of ownership.

The Beijing NOVICK AF Series has established a complete after-sales service system covering installation and commissioning, operation training, remote diagnostics, and spare parts supply. If you are evaluating die-sinking EDM machines, we suggest placing after-sales service terms on an equal footing with equipment performance. It is also worthwhile to learn about the service experience of local users – word of mouth is the best proof.
