[Processing Example] Industrial Machinery (Hydraulic and Cooling Mechanisms) Industry

Introducing examples of achieving stable flow, reduced assembly man-hours, and high reliability!

We would like to introduce a case study on the processing of center holes in long shafts used as oil and cooling passages inside industrial machinery. In this case, there were challenges such as the long, thin diameter being prone to bending and difficulties in internal heat and chip discharge. However, through our company's efforts, we achieved stable flow rates, reduced assembly man-hours, and high reliability. Our company has many years of experience and advanced technology in the field of deep hole processing and gun drilling. Utilizing advanced gun drilling technology that enables precise deep hole processing, we provide high-quality machining services tailored to our customers' needs. 【Case Overview】 ■ Industry: Industrial Machinery (Hydraulic and Cooling Mechanisms) ■ Part Information: DAC material, φ3×351mm, L/D=117, concentricity 0.15 to 0.19mm ■ Challenges: Long, thin diameter prone to bending / Difficulties in internal heat and chip discharge ■ Value Provided: Successful penetration even with L/D over 100 / Achieved exit eccentricity of less than 0.2mm ■ Technical Points: Feed control, high-pressure coolant, tool life monitoring, dedicated deep hole equipment *For more details, please download the PDF or feel free to contact us.
