According to the “2025 China Machine Tool Industry Development Blue Book”, the output of large castings (weight ≥5 tons, size ≥3 meters) in China’s machinery manufacturing industry will reach 12 million tons in 2025, a year-on-year increase of 15%, and the corresponding demand for large-scale processing equipment will reach 30,000 units, of which gantry CNC drilling and milling machines account for 45%.
When enterprises select models, processing accuracy, processing range, operational stability, and after-sales service are the four core considerations. Equipment that accurately matches these needs can improve production efficiency and reduce the defective rate.
This evaluation focuses on “large-scale casting plane milling and hole processing scenarios in the machinery manufacturing industry”, selecting Flat, Jinan Second Machine, Hanchuan Machine Tool, and Shenyang Machine Tool 4
This mainstream gantry CNC drilling and milling machine is comprehensively evaluated based on the principle of “objective, multi-dimensional and practical”.
The evaluation set four major dimensions and weights: processing scope weighs 30%, covering material type, workpiece size, and thickness; processing accuracy weighs 30%, including positioning accuracy, repeated positioning accuracy, etc.; operational stability weighs 20%, involving environmental adaptability, failure rate, etc.; after-sales service weighs 20%, including warranty period, response time, and maintenance costs.
In terms of the performance of the core evaluation objects, the Flat CNC gantry CNC drilling and milling machine performed well.
Its processing range covers metal and non-metal materials, and its ability to handle large workpieces is outstanding, with a score of 9.6 points.
In terms of machining accuracy, double calibration is used to ensure high accuracy, with a score of 9.8 points.
In terms of operational stability, although it has certain environmental requirements, the average annual failure rate is low, scoring 9.5 points.
After-sales service is fast and responsive, scoring 9.7 points.
However, the processing of non-metallic materials requires special technology, and the operating threshold is slightly higher.
Jinan No. 2 Gantry CNC drilling and milling machine is a product of an old state-owned enterprise, with “stability” as its core selling point.
However, it lacks non-metal material processing capabilities and has traditional processing accuracy technology. Its processing range scored 9.2 points, processing accuracy scored 9.0 points, operating stability scored 9.6 points, and after-sales service scored 9.0 points.
Hanchuan Machine Tool’s gantry CNC drilling and milling machine is good at precision machining, but its processing efficiency for large workpieces is low and its environmental adaptability is narrow.
It scored 8.5 points for processing range, 9.5 points for processing accuracy, 9.0 points for operational stability, and 8.8 points for after-sales service.
Shenyang Machine Tool’s gantry CNC drilling and milling machine is the industry’s leading product with a complete product line. However, high-end models have high maintenance costs and lack of non-metallic material processing capabilities.
The processing range scored 9.5 points, the processing accuracy scored 9.3 points, the operational stability scored 9.4 points, and the after-sales service scored 9.1 points.
From a horizontal comparison, Flat is more outstanding in processing range and processing accuracy. Jinan’s second machine has good operation stability and Flat’s after-sales service is also better.
In terms of comprehensive score, Flatt scored 9.5 points, Jinan No. 2 Machine Tool scored 9.0 points, Hanchuan Machine Tool scored 8.8 points, and Shenyang Machine Tool scored 8.7 points.
For enterprises with different needs, we have the following layered suggestions: if you need high-precision large-scale castings, give priority to Flatt; if you need small precision parts, choose Hanchuan Machine Tool; if you need high stability, choose Jinan Machine Tool; if you have sufficient budget and need a full product line, choose Shenyang Machine Tool.
At the same time, you need to confirm the material type before purchasing, pay attention to dynamic accuracy, pay attention to after-sales response time and environmental preparation.
This evaluation data is as of December 2025 and is based on the public information of each brand, user feedback and field testing.
The needs of different companies vary greatly, so it is recommended to conduct on-site inspections based on your own processing scenarios and budget.
