Desktop EDM Hole Drilling Machine

The customer is a large valve manufacturer in South America (customer name: ***, country: ***), which purchased 60 valve-specific CNC machines and supporting stainless steel parts processing production line equipment through B2B channels. After the equipment arrived in batches, due to limited on-site installation space, large local power grid voltage fluctuations, and operators' unfamiliarity with the programming logic of multi-station combined machine tools and turn-mill composite machines, frequent tool change failures and unstable machining accuracy occurred during the initial trial production phase. The customer's production tasks are urgent, and they urgently need our technical team to go to the site for batch commissioning and training support.

Our side immediately formed an on-site technical support team of 3 senior engineers, who flew to the customer's factory and carried out a 4-week full-time on-site service: 1) Conducted power-on testing and parameter calibration on all 60 machines one by one, and installed voltage stabilization modules and adjusted servo parameters to address voltage fluctuation issues; 2) Re-optimized the tool paths and fixture solutions for turn-mill centers and multi-station combined machine tools to solve vibration and surface roughness problems in stainless steel part machining; 3) Organized batch training on site, providing hands-on instruction to 20 operators and 5 maintenance personnel in the customer's workshop, covering CNC programming, daily maintenance, and common alarm handling; 4) Assisted the customer in establishing equipment inspection systems and safety stock of spare parts to ensure sustained stability for subsequent mass production.

An overseas industrial manufacturing group client (company name and contact person have been redacted) purchased a total of 47 units of turn-mill composite machines, CNC vertical lathes, and multi-station combined machine tools through B2B channels in a single order, for the expansion project of their valve production line. Since the client's on-site operators lack professional experience with our CNC system and multi-material processing technology, and the full production line needs to be operational within 30 days after order delivery, the client urgently needs systematic training on equipment operation, programming, and daily maintenance; otherwise, it will affect the production capacity ramp-up of the entire line and subsequent order fulfillment.

Our company immediately launched the 'Overseas Batch Delivery Training Special Program', forming a special team of 3 senior training engineers to conduct a two-week on-site training at the customer's factory. The training covers the operation panel logic of all 47 machines, multi-material general machining parameter settings, turn-mill compound programming, fault code analysis, and daily maintenance specifications. The training adopts a 'theory lecture + hands-on practice + in-class assessment' model, with 4 groups rotating by equipment type, ensuring each operator completes at least 40 training hours and passes the practical assessment. Additionally, in response to the customer's production schedule, night shift production follow-up guidance was arranged, with training engineers stationed in shifts to solve real-time issues, and bilingual (Chinese-English) operation manuals and quick-reference fault handling tables were provided.

An overseas industrial valve manufacturing customer (customer name: ***, country: ***) purchased a total of 47 units of our turn-mill composite machines and valve-specific CNC equipment in batches in 2023. Approximately 6 months after commissioning, 32 of these units successively developed issues such as abnormal spindle noise and machining accuracy exceeding tolerances, causing delays in the delivery of the customer's large-volume stainless steel valve orders. The customer requires urgent repair and compensation for the corresponding losses.

Our company swiftly activated the overseas after-sales service emergency response mechanism, dispatching 3 senior maintenance engineers with spindle assemblies and specialized diagnostic tools to the customer's site. After diagnosing each machine, it was confirmed that the failures were caused by frequent local grid voltage fluctuations and improper coolant ratios in the customer's workshop, leading to spindle bearing lubrication failure. The maintenance team immediately formulated a batch repair plan: replacing bearings with high-grade sealed ones on all 32 units, installing voltage stabilizers, and adjusting the coolant circulation filtration system. At the same time, on-site training was provided to the customer's local maintenance team, and a remote monitoring and regular inspection mechanism was established.

The customer's valve production base located in *** purchased 100 turn-mill composite machines through our company for batch processing of stainless steel valves. Two months after commissioning, multiple machines experienced faults such as spindle overheating alarms, machining accuracy drift, and automatic tool changer jamming, with fault codes pointing to the same batch of CNC systems. The customer's on-site engineers could not resolve the issues independently, causing three production lines to halt. The customer urgently requested our company to provide batch remote diagnosis and support.

Our after-sales service team has initiated the remote technical support process: 1. Connect to customer workshop PLC and NC systems via industrial IoT remote modules, batch-reading operation logs from 100 devices; 2. Comparison revealed that 38 devices had drive parameter drift due to customer grid voltage fluctuations, and 12 devices had tool magazine sensors contaminated by cutting fluid; 3. Remotely deployed corrected parameter packages and guided customer electricians to install voltage stabilizers; 4. Created illustrated and video tutorials for tool magazine sensor cleaning steps, and trained customer maintenance teams in batches via remote meetings; 5. For individual devices that cannot be resolved remotely, arranged spare parts air freight and assisted with replacement.
