Mechanical Service In order to reach the customer's requirements, we have expanded our Machining Services. We now specialize in other services such as Deep Hole Drilling, Precision Grinding, and Welding. Each time we came upon a part which required an outside Machine Shop service, we asked ourselves if we could do that service in workshop. Step by step we added a broad range of different capabilities. The first service that we added was Welding. Customer demand required that we not only just machine, but also that we fabricate. We now employ welders that specialize in TIG, and MIG welding. A bit later we decided to add a Gundrill machine to compliment our growing Honing Department. We are able to drill from 1/8 inch to 20 inches diameter, in all types of materials. Most of the time we will drill a hole on our GunDrill, and then we can Hone it to a precise tolerance and a mirror finish. Recently we have added a couple of machines to expand our Grinding capabilities.

Technical characteristic Adopting the advanced production line crack detecting, quenching, the continuous overall tempering and sand blasting processes to achieve higher mechanical strength ability with overall good performance. 1 íóThe thread is cut by the special-purpose numerical control lathe which keeps the rod body still when cutting the threads. The special process could ensure the high precision of the thread with better reliability and life-span. 2 íóCoupling phosphor or copper coated to achieve good wearing-resistance ability and anti-thread gluing ability.

A. Slick Drill Collar Note: Drill collar is mainly used to provide bit weight to drill bit so that drill pipe is in tension. Especially drill collar can keep drill bit centralized and hole track by large rigidity. The Drill collar are manufactured strictly from API Spec7-1 and SY5411 standard. B. Spiral Drill Collar Note: Spiral drill collar is used to reduce contact area with hole so as to avoid efficiently bit sticking from diffirential pressure. The drill collars are manufactired strictly according to API Spec7-1 and Standard SY5144 C. Spiral Drill Collar With Elevator Groove And Slip Groove Note: Elevator groove and slip groove made on box thread face of slick drill collar or spiral drill collar can be used as lifting sub and safety slip when trip out. The technical parameters for elevator groove and slip groove is as per API SPEC7-1. Hardbanding is optional at customersâ?? requests. D. Non-magnetic Drill Collar The as cold rooled finish on both ID and OD surface with unique technical process strengthen the structure and ensures the tools with optimal resistance to stress,corrosion,cracking and the mechanical performance is greatly enganced.

1) High-strength,high flexibility,high temperature,high wear resistance. 2) High-precision metal seal. 3) locking roller ball,to adapt to high-speed. 4) The use of high strength hig toughness carbide teeth. 5) Hours in the rotary cone bit with the impact,crushing and shearing the role of broken rock. 6) cone bit to adapt to the soft,medium and hard of various strata. 7) Reasonable price and long working life.
