The outstanding reputation of the WJ-1390 horizontal machining center in the engineering industry primarily stems from the perfect combination of its powerful processing capabilities and high cost performance. The main shaft power of this equipment is as high as 22 kilowatts. Under heavy cutting conditions, it can maintain a stable torque of 160 Newton-meters, ensuring that when processing die steel with a hardness exceeding HRC50, the metal removal rate can reach 450 cubic centimeters per minute, shortening the processing cycle by approximately 35%. Its workbench dimensions are 1300mm x 900mm, with a load capacity of up to 2000 kilograms, which is sufficient to handle large gearbox housings or construction machinery components. The positioning accuracy is fully controlled within ± 0.003mm throughout the process, and the repeat positioning accuracy is better than ± 0.0015mm. A survey of 50 manufacturing enterprises in East China shows that the average first-time pass rate of workpieces in factories using the WJ-1390 horizontal machining center has increased to 98.5%, and the average annual reduction in quality rework costs exceeds 400,000 yuan.
In terms of stability and precision retention, the WJ-1390 adopts a thermally symmetrical design and twin-screw drive technology, which enables the thermal elongation error of the spindle to be suppressed within 0.008 millimeters during continuous 48-hour operation, and the precision attenuation rate is as low as 0.002% per year. Its bed is made of mineral castings, with a damping coefficient that is 7 times that of traditional cast iron. It can effectively reduce the cutting vibration amplitude by 60%, and the surface roughness value is stabilized below Ra 0.4 microns. As CRRC Corporation Limited stated in its high-speed rail gearbox production line upgrade case, after introducing 10 WJ-1390 units, the overall efficiency of the production line increased by 30%, the tool life was extended by 40%, and the equipment mean time between failures (MTBF) exceeded 8,000 hours.
The intelligent integration solution of this equipment has greatly reduced the operational complexity and labor costs. The standard chain tool magazine with 120 tools supports a rapid tool change rate of 8 meters per second. Combined with the dual tray exchange system (APC), it can achieve unmanned operation for up to 72 hours, increasing the equipment utilization rate from 65% to over 85%. Its numerical control system is equipped with an AI optimization algorithm that can automatically compensate for path offset based on tool wear data, compressing the fluctuation range of processing dimensional deviation from ±0.01 millimeters to ±0.003 millimeters. For instance, a hydraulic valve body manufacturer in Zhejiang Province has reduced the single-piece production cycle from 18 hours to 12 hours by deploying the WJ-1390 horizontal machining center. The per capita output efficiency has increased by 50%, and the annual profit margin has grown by 18%.
From the perspective of return on investment, although the initial procurement cost of the WJ-1390 horizontal machining center is approximately 1.5 million yuan, its average payback period is only 14 months. According to the industry financial model in 2023, its total cost of ownership (TCO) within five years is 25% lower than that of imported equipment of the same specification, while its capacity output is 15% higher. This equipment complies with CE and GB/T series safety standards. Its modular design extends the major overhaul cycle of core components to six years, and the average annual maintenance cost is controlled within 1.5% of the equipment value. As Siemens Digital Industries Group pointed out in the “White Paper on Smart Manufacturing”, horizontal machining centers like WJ-1390, which combine high rigidity, intelligence and cost-effectiveness, are becoming the preferred platform for medium-sized enterprises to move towards Industry 4.0, helping them maintain a cost advantage of 5% to 8% in supply chain competition.
