With the continuous development and expansion of our company and the implementation of the global strategic layout, our company's foreign trade has gradually won the trust and support of many foreign customers.

When the repaired seal between the valve and the valve seat fails to meet the requirements, or when the valve and the valve seat are found to have slight ablation or spots during regular maintenance, the grinding method should be used to achieve the valve fit requirements.

In November, customer form Indian Rane Engine Valve Limited visited JNH Machinery. We are glad to welcome this special visit.

Grinding is used for finishing workpieces requiring high surface quality (e.g. low surface roughness) and high shape and dimensional accuracy.
