[Development Case] Deburring of Holes in Injector Parts
Through-hole of small diameter deep hole by diameter reduction extrusion! Abolition of punching in the middle section of small diameter deep holes.
We would like to introduce a development case for deburring the inner holes of injector components. We adopted a new method for penetrating small-diameter deep holes using diameter-reducing extrusion, achieving non-cutting of the inner diameter through small-diameter deep hole penetration, which improved precision and cleanliness. Additionally, we eliminated punching in the intermediate section of the small-diameter deep hole. The coaxiality improved from φ0.15 to φ0.05. 【Development Objectives】 ■ New Method: Penetration of small-diameter deep holes using diameter-reducing extrusion ■ Improved Precision and Cleanliness: Non-cutting of the inner diameter through small-diameter deep hole penetration ■ Novelty: Elimination of punching in the intermediate section of small-diameter deep holes *For more details, please download the PDF or feel free to contact us.
