Aerospace components are mostly made of difficult to cut materials such as titanium alloys and high-temperature alloys, with complex and irregular shapes and strict geometric tolerances. Many processing plants face practical difficulties: traditional processing requires the circulation of multiple lathes and milling machines, repeated disassembly and alignment of workpieces, large accumulated clamping errors, and high scrap rates during small-scale trial production. At the same time, the cutting process of high-temperature alloys generates severe heat, ordinary machine tools have large thermal deformation, and the machining dimensions are prone to drift for a long time, making it difficult to maintain micrometer level accuracy stably. The procurement cost of imported equipment is also high, which puts pressure on many supporting enterprises.
To excel in the processing of aviation components, the rigidity, thermal stability, and composite processing capability of machine tools are indispensable. The Harman Precision EX turning and milling composite series and high-precision standard series rely on the Mihanna cast iron integrated bed body, combined with FEM finite element simulation optimization structure. The machine tool has excellent seismic and vibration absorption performance, effectively suppressing vibration in the face of difficult to cut materials and heavy cutting conditions. The whole machine is equipped with multi-point temperature sensors and thermal compensation devices, which weaken the thermal displacement caused by the environment and cutting heat, ensuring stable long-term machining accuracy.
The equipment supports one-time clamping to complete all processes of turning, milling, drilling, and boring, reducing the need for multiple workpiece transfers and avoiding positioning deviations caused by repeated clamping. The dual spindle model can complete synchronous machining of both ends of shaft structural components, with excellent coaxiality control performance. Not only can it adapt to mass production, but it can also meet the needs of small batch sampling and trial production of new products.
In addition to hardware, process matching is equally crucial. After purchasing equipment, many companies lack mature cutting parameter references and have long debugging cycles. Harman Precision Machinery relies on a large number of industry processing cases to provide customers with customized process evaluations, cutting parameter recommendations, and personnel operation training. Local service network ensures rapid response to faults, reduces equipment downtime losses, assists aviation supporting enterprises in balancing quality and production costs, and achieves domestic processing of high-end components.
