Product Description

Metal processing expertise

Sanluo Precision Company has extensive practical experience and possesses mature Metal CNC Machining technology. It is proficient in processing various materials and has expertise in precision machining of aluminum alloys and copper alloys. It conducts appropriate aging treatment on various types of aluminum alloys such as 2 series, 6 series, and 7 series to achieve the precision target for controlling deformation. The factory makes full use of the high strength, superior machinability, and super hardness characteristics of aluminum alloys. For copper alloy processing, it can machine alloy materials such as H62 brass, T2 copper, and C17200 beryllium copper. By adjusting cutting parameters according to different alloy characteristics, it can achieve better surface roughness and dimensional stability. Additionally, we have our own methods for processing high-hardness materials. It can machine stainless steel 17-4PH (HRC38-42), tool steel SKD11 (HRC58-62), and steel with hardness above HRC50. Using hard alloy tools and slow feed, small cutting depth, etc., the entire processing process is stable and of high precision. For ultra-hard materials, Metal CNC Machining can also use special processing techniques such as electrical discharge machining and wire cutting.
