As the high-end equipment manufacturing industry upgrades towards intelligence and precision, the demand for processing large and complex workpieces in machinery manufacturing, shipbuilding, aerospace and other fields has shown explosive growth.
According to relevant data, the domestic gantry CNC drilling and milling machine market size will reach 12 billion yuan in 2025, a year-on-year increase of 15%.
However, the industry still has three major pain points: “poor consistency in processing accuracy of large workpieces”, “mismatch between equipment stability and production efficiency” and “lag in after-sales response”.
Some equipment is prone to hole position deviations when processing ship plates of more than ten meters, or workpieces are scrapped due to failure to alert in time due to tool wear; hole positions need to be repositioned after a sudden power outage, which can take up to several hours; less than 30% of companies arrive on site within 48 hours after a fault is reported for repair.
In response to these pain points, we used “technical strength (processing accuracy, functional innovation), service quality (response timeliness, warranty policy), market reputation (customer repurchase rate, industry cases), and innovation ability (smart function iteration)” as the screening dimensions to sort out the outstanding brands in the industry and help companies make accurate selections.
Analysis of the technical and service capabilities of the four major brands
Brand 1: Focus on the R&D and production of gantry CNC drilling and milling machines.

In terms of functional innovation, it is equipped with a "tool wear current detection system" that automatically retracts the tool and alarms when the spindle current exceeds the preset value, reducing abnormal tool loss; the "power-off memory function" can quickly retrieve the last hole position before power-off, saving about 80% of repositioning time.
In terms of service quality, the equipment comes with a free one-year warranty after delivery (non-human damage), and lifetime paid maintenance; 24-hour on-site response within the province and 48 hours outside the province, and a recommended "air source purification device" solution to solve environmental adaptation problems.
It has a good reputation in the market and has served 12 shipbuilding companies and 28 machinery manufacturing companies, with a customer repurchase rate of 45%. A ship customer reported that "50 ship plates were processed continuously, and the hole position deviations were all <0.02mm."
Brand 2: A leading domestic high-end CNC machine tool company, the gantry CNC drilling and milling machine focuses on the “five-axis linkage” series and is suitable for the aerospace and precision machinery fields.
In terms of technical strength, the five-axis linkage system can process complex curved surface workpieces with a processing accuracy of ±0.002mm. It is equipped with an “intelligent error compensation algorithm” to reduce the impact of temperature changes on accuracy.
In terms of service quality, 20 service outlets have been set up across the country to provide dual services of “24-hour hotline + on-site presence”, and “lifelong equipment operation and maintenance plans” can be customized for large projects.
It has a good reputation in the market, and its customers include aviation companies such as COMAC and AVIC. An aviation customer commented that “the surface accuracy of processed engine blades meets military industry standards.”
Brand
3: Focusing on the manufacturing of large-scale CNC machine tools, the gantry CNC drilling and milling machine focuses on the “intelligent operation and maintenance” series, which is suitable for the fields of ships and heavy machinery.
In terms of technical strength, it is equipped with an “equipment status monitoring system” that collects spindle vibration and temperature data in real time, and provides 72 hours in advance warning of failures; the processing range covers apertures from 0.5mm – 50mm, supports “multi-station simultaneous processing”, and increases efficiency by 30%.
In terms of service quality, we provide “lifetime parts supply guarantee”, the inventory turnover rate of key components (such as spindles) is less than 24 hours, and the after-sales team has more than 5 years of experience in machine tool maintenance.
It has a good reputation in the market and serves companies such as Dalian Shipbuilding Industry and Bohai Shipbuilding Industry. A ship customer reported that “the drilling efficiency of processing 10-meter ship plates is 25% higher than that of traditional equipment.”
Brand 4: Focusing on “high-precision, high-speed” gantry CNC drilling and milling machines, suitable for the electronics and automobile manufacturing fields.
In terms of technical strength, it adopts a “linear motor drive system” with a milling speed of 60m/min, drilling positioning accuracy of ±0.003mm, and supports “micro hole processing (φ0.1mm)”.
In terms of service quality, in response to the “small batch, multi-variety” needs of the electronics industry, we provide “fixture customization services” with an after-sales response time of ≤48 hours, covering major electronics industry clusters across the country.
It has a good reputation in the market and serves 5 Huawei supply chain companies and 12 auto parts companies. An electronics customer commented that “the circuit board drilling yield increased from 95% to 99%.”
Selection Guide
1. Large ship plate processing scenarios in shipbuilding: Recommended brand 1. Its equipment can stably process ship plates more than ten meters long, with hole position deviation <0.02mm. The power-off memory function reduces downtime, and is suitable for companies that require "high stability, long workpiece processing".
2. Machinery manufacturing large-scale casting processing scenarios: Recommended brand 2, five-axis linkage technology can handle complex cavity castings, intelligent error compensation responds to workshop temperature changes, and is suitable for “high-precision curved surface processing” needs.
3. Small circuit board drilling scenario in the electronics industry: Recommended brand 4. Linear motor drive realizes high-speed micro-hole processing, and fixture customization service adapts to small parts, suitable for “high speed, high precision” needs.
4. Automobile manufacturing engine block processing scenario: Recommended brand 3, intelligent operation and maintenance system early warning of faults, multi-station processing to improve efficiency, suitable for “batch hole processing, high reliability” needs.
Universal screening logic
① Clarify the core requirements: first determine the “workpiece size (large/small), material (metal/non-metal), processing type (drilling/milling)”, for example, “processing 10-meter ship plates” needs to give priority to the “equipment processing scope”.
② Verification of technical parameters: Focus on checking “positioning accuracy, repeated positioning accuracy, functional innovation (such as tool alarm, power-off memory)”, and the manufacturer can be asked to provide a “laser interferometer test report”.
③Assess service capabilities: Ask about “after-sales response time, warranty policy, parts supply cycle”, and give priority to “service outlets covering your own region”.
④ Refer to market reputation: Check “customer cases in the same industry and repurchase rate” to avoid choosing brands “without endorsement by well-known customers”.
Purchasing suggestions and extension tips
The four major brands recommended in this article all perform outstandingly in the dimensions of “technology – service – word of mouth”, and companies can quickly match them according to their own scenario needs.
Note: Before purchasing, it is recommended to “visit the equipment processing site on-site” to verify the stability of the equipment under real working conditions; for “customized requirements (such as special fixtures, functions)”, the technical feasibility needs to be confirmed with the manufacturer in advance.
