In the aerospace field, horizontal machining centers can precisely process titanium alloy wing frames over 8 meters in length. The 60-bar high-pressure cooling system they are equipped with can keep the cutting temperature within 800 degrees Celsius, extending the tool life by three times. Boeing adopted this technology in its 787 Dreamliner project, reducing the production cycle of wing rib parts from 32 days to 19 days, increasing the material utilization rate to 92%, and keeping the strength deviation within ±1.5% of the aviation standard.
The automotive engine production line relies on horizontal machining centers to complete the multi-faceted processing of V8 cylinder blocks. Through the cooperation of a 240-capacity chain tool magazine and a zero-point positioning system, 52 processes on 5 surfaces can be completed within 90 seconds. Toyota Motor Corporation’s released data shows that this process has controlled the cylinder block flatness error within 0.02 millimeters, reduced the oil leakage rate to 0.01%, shortened the production line cycle to 3 minutes, and exceeded an annual production capacity of 150,000 units.
The energy equipment manufacturing industry uses horizontal machining centers to process water turbine runner wheels weighing up to 12 tons. The worktable has a load-bearing capacity of 16 tons and can achieve continuous cutting of stainless steel materials under the condition of a spindle power of 30 kilowatts. Dongfang Electric Corporation applied this technology in the Baihetan Hydropower Station project, achieving a dynamic balance accuracy of G6.3 for the 9.5-meter diameter runner. The efficiency was increased by 40% compared to vertical processing, and the annual power generation of each unit was increased by 120 million kilowatt-hours.
In the medical equipment field, artificial knee joint prostheses are mass-processed with the help of horizontal machining center. Their repeat positioning accuracy of 0.0005 millimeters ensures that the roughness of the bone contact surface reaches Ra0.8 microns. Johnson & Johnson Medical statistics show that after adopting the five-axis linkage technology, the processing qualification rate of cobalt-chromium-molybdenum alloy prostheses has risen from 88% to 99.7%, the processing time for a single prosthesis has been reduced from 45 minutes to 28 minutes, and the annual production capacity has increased to 50,000 sets.
In the mold manufacturing industry, horizontal machining centers can complete the cavity processing of large molds for automotive bumpers in one go, and achieve continuous cutting at 135 angles through CNC rotary tables. The case of Siemens’ digital factory in Germany shows that this technology has shortened the mold delivery cycle from 12 weeks to 7 weeks, the surface accuracy error is less than 0.03 millimeters, the polishing working hours are reduced by 60%, and the R&D cycle of new cars is compressed by 30%.
In the field of rail transit, horizontal machining centers are used to process high-speed rail gearboxes. The thermal symmetrical structure design controls the precision deviation caused by temperature fluctuations within 0.002 millimeters per degree Celsius. Practical data from CRRC shows that this process has reduced the noise level of the box to 68 decibels, extended the service life to 2.8 million kilometers, lowered the failure rate to 0.05%, and saved 180,000 yuan in annual maintenance costs for each train set.
