Compared to machining from solid, our gravity casting solution significantly reduces material waste and cycle times, lowering overall costs while offering superior vibration damping properties.
We utilize aluminum gravity casting to produce the main structural shapes. Gravity cast workpieces offer stable quality, high dimensional accuracy, and low surface roughness, significantly reducing subsequent machining requirements. The spindle housing for PCB drilling machines demands strict dimensional precision: tolerances within 10µm, form tolerances within 15µm, and surface roughness (Ra) under 1.6. We accept custom specifications and deliver fully assembled upper and lower housing units.
