Abstract
This article introduces the successful application of Shandefu Long Force Drills K Series in oil-rock tooth hole machining. Through optimization by our engineers and with the support of our clients, this drill not only meets the high precision and surface finish requirements but also significantly reduces production costs. Below is a detailed case study and processing parameters.
Introduction
In the oil-rock tooth hole machining industry, clients have extremely high requirements for the precision and hardness of the workpieces. Using ordinary drills cannot achieve the required precision and surface finish, while using top-tier tools from Germany and Switzerland is too costly. To meet client needs, Shandefu engineers optimized the drill and now offer it as a standard product. If you have any requirements, you can contact us directly to purchase without customization.
