Three coordinate detection equipment accessories
core advantages of cast aluminum parts for main columns
The main column of the three coordinate detection equipment accessories is the Z-axis core bearing and motion reference component of the equipment, which directly determines the measurement accuracy, motion stability, and long-term stability of the whole machine. Compared to traditional cast iron and ordinary steel structures, cast aluminum main columns have become the preferred structural solution for high-precision, high-speed, and portable three-dimensional detection equipment due to their material characteristics and precision casting processes
1, High specific stiffness, low inertia, suitable for high-speed precision measurement.
Adopting precision casting of aluminum alloy, the self weight of the column is significantly reduced compared to cast iron columns, while ensuring structural rigidity and compliance with bending and torsion resistance standards. The lightweight structure can greatly reduce the Z-axis motion inertia, making the column start stop response faster and run smoother, effectively eliminating the problems of traditional heavy column start stop and micro motion offset, perfectly adapting to the work requirements of high-speed scanning, continuous point taking, and precision retesting of three coordinate equipment, significantly improving the measurement efficiency and detection repeatability accuracy of the whole machine.
2, Excellent thermal stability, significantly reducing temperature errors.
Cast aluminum material has excellent uniform thermal conductivity, with a much higher heat conduction rate than cast iron and steel, which can achieve rapid temperature balance of the entire column.
3, Thorough stress release, long-term zero dimensional drift.
The main column is formed using precision casting technology, combined with professional vibration aging and heat treatment processes, to comprehensively eliminate residual stresses inside the casting and avoid deformation, warping, and dimensional drift caused by natural stress release in the later stage.
4, Corrosion and weather resistance, suitable for complex working conditions in the workshop.
The cast aluminum main column undergoes hard anodizing and precision surface strengthening treatment, resulting in high surface hardness, oxidation resistance, corrosion resistance, and resistance to rusting. Cast aluminum columns do not require frequent rust prevention maintenance and can adapt to complex working environments such as humidity, dust, and slight oil stains in mechanical processing workshops for a long time. Their appearance and structural performance are stable for a long time.
5, Integrated molding has high precision and strong assembly adaptability.
Adopting an integrated integral casting process to avoid stress concentration and assembly errors in splicing and welding structures, coupled with five axis CNC precision machining, the precision of the guide rail installation surface, benchmark positioning hole, and assembly joint surface is extremely high, and the tolerance control of flatness, perpendicularity, and parallelism is strict.
6, Lightweight and low load, extending the overall lifespan of the equipment.
The lightweight feature of cast aluminum main columns significantly reduces the load-bearing capacity of equipment guide rails, transmission modules, and servo motors, reduces motion friction losses and transmission fatigue, lowers equipment operating noise and failure rates, and effectively extends the service life of the entire machine's transmission components and precision guide rails.
