high precision punch press

open back press hydraulic overload protector Dry pneumatic friction clutch shearing block protector

feature:

1. The body of JH21 series press is welded with steel plate ,so it is with good rigidity and stable precision .

2. The crankshaft is placed lengthways ,so the structure is compact and the contour beautiful .Using the combined pneumatic friction clutch and brake ,the engagement is smooth ,the action agile ,and the noise low .gear pair adopts the flooding system lubrication .
