A strict system of raw material inspection, semi-finished product inspection, finished product inspection, and installation process inspection has been implemented. In order to ensure the quality of each batch of products, sampling inspections are carried out, and the sampled products are qualified in the simulation experiment.
The production line covers more than 100 models of all common sizes and types which be widely used in the various types drilling platforms, several advanced production lines featured in CNC, turning, carburizing, polishing ,drilling, and milling,etc.special for high-performance processing, with the annual production capacity of more than 5000 pcs and more than 100 workers in the production line workshops. Applications include mining, drilling, water well, pilling,crude oil,geological and natral gas exploration HDD etc. We provide tricone bits from 4 1/2" to 34",PDC bits from 2 7/8” to 28”,piling from 60cm to 200cm,HDD vertical reamer and rock reamer from 8” to 45 inch。
