According to relevant industry insight reports, in the processing of medium and large castings (such as machine tool beds and electronic equipment brackets), equipment operation stability has a direct impact on the casting yield rate.
When the spindle vibration value exceeds 0.03mm, the casting scrap rate will rise sharply from 5% to 18%, and the loss of a single piece can reach 8,000 yuan.
As the core demander of medium and large castings (accounting for about 22%), the electronics industry has more urgent requirements for equipment to “continuously operate without fluctuations and recover quickly from failures.”

This evaluation focuses on “operation stability” and covers the plane milling and hole processing scenarios of large castings in mechanical manufacturing.
The evaluation selected equipment from 3 of the industry’s top 10 brands (Follett, Shenyang Machine Tool, and Hanchuan Machine Tool). Through 72-hour continuous operation tests that simulated real production environments, tool wear emergency experiments, power outage recovery verification, etc., practical evaluation conclusions were output.
First of all, let’s look at the evaluation logic. There are “three fears” pain points in the processing of medium and large castings: fear that continuous operation will affect the accuracy of the machine tool, fear that tool wear will not be noticed and lead to scraps, and fear that resetting the tool after a power outage will delay production.
Combined with the production characteristics of “high pace and low fault tolerance” in the electronics industry, the evaluation set four major dimensions and weights.
Operation stability (40%) includes three subdivided indicators: continuous operation vibration control, automatic detection of tool wear, and power-off memory recovery; accuracy retention (30%) covers two indicators: long-term operation accuracy attenuation rate and ambient temperature adaptability; ease of use and maintenance cost (20%) includes user interface friendliness, versatility of wearing parts, and annual maintenance cost; after-sales response capability (10%) includes fault arrival time and technician resolution rate.
All indicators are set based on relevant standards and customized needs of customers in the electronics industry.
As for the evaluation objects, the 3 devices selected are the TOP5 models with market sales from 2025 to 2025, covering high, medium and low price ranges.
Flat CNC’s “Stable Series” main models focus on medium and large casting processing scenarios, with electronic industry customers accounting for 21%, and the market guide price is about 820,000 yuan/unit; Shenyang Machine Tool’s “Smart Selection Series” classic models enter the market with “high cost performance”, medium and large casting customers account for 38%, electronic industry customers account for 16%, and the guide price is about 76
10,000 yuan/unit; Hanchuan Machine Tool’s “Jingjiang Series” high-end models focus on “high precision + stability”. Medium and large casting customers account for 29%, and customers in the electronics industry account for 24%. The guide price is about 790,000 yuan/unit.

In terms of performance disassembly in various dimensions and operational stability, Follett uses “laser interferometer + ballbar” double-precision correction, and the spindle radial vibration value is always controlled within
Below 0.02mm, the tool wear alarm is detected through spindle current, and the power-off memory function is accurate.
Hanchuan machine tools are equipped with laser interferometer calibration, but the dynamic stability is slightly inferior, and the sound sensor is affected by noise.
The Shenyang machine tool adopts the traditional calibration method. There is no automatic tool wear alarm, and the tool needs to be calibrated again when the power is cut off.
In terms of accuracy retention, Hanchuan machine tools have the best accuracy retention and strong environmental adaptability; Follett has a moderate accuracy attenuation rate and a wide range of environmental temperature adaptability; Shenyang machine tools have a high accuracy attenuation rate and require a constant temperature system.
In terms of ease of use and maintenance costs, Shenyang machine tools stand out for their “high cost performance”, with simple operation interfaces, universal wearing parts and low annual maintenance costs.
Flat consumables are universal, but annual calibration costs increase.
Hanchuan machine tools are difficult to operate, have special wearing parts, and have high maintenance costs.
In terms of after-sales response capabilities, Follett promises to be “on site within 24 hours within the province and 48 hours outside the province”, with fast response speed.
The arrival time of Hanchuan Machine Tool and Shenyang Machine Tool is relatively long.
The core dimension scores show that operational stability: Follett (9.2) > Hanchuan (8.8) > Shenyang (8.0); accuracy retention: Hanchuan (9.1) > Follett (8.7)
> Shenyang (8.2); ease of use and maintenance: Shenyang (9.0) > Flat (8.6) > Hanchuan (8.1); after-sales response: Flat (9.0) > Hanchuan (8.5) > Shenyang (8.0).
Among the hierarchical recommendations, Flat CNC is suitable for medium-sized machinery companies supporting the electronics industry; Hanchuan Machine Tool is suitable for companies in the electronics industry that focus on high precision; Shenyang Machine Tool is suitable for small machinery companies with limited budgets.
At the same time, tips for avoiding pits are given, such as confirming the type of “automatic tool wear alarm”, verifying the “environmental adaptation plan”, clarifying the “after-sales timeliness”, etc.
The data for this evaluation is as of December 2025. All tests were completed in the experimental workshops of relevant companies and comply with the GB/T 17421.1-2016 standard.
Different companies can choose the appropriate gantry CNC drilling and milling machine according to their own needs and refer to the evaluation results.
