The mining industry demands components that can handle extreme wear, high loads, and constant stress. Equipment used for drilling, excavation, hauling, and mineral processing must be built to perform without failure. One weak point in a part—especially in high-torque or deep-excavation systems—can disrupt operations and lead to significant losses.
Machined parts play a key role in this environment. From drilling assemblies to hydraulic systems, the quality of internal surfaces, straightness, and bore alignment directly impacts equipment reliability. Heavy machinery, often operating around the clock, depends on exact tolerances to maintain safe and consistent function.
Long-Term Support for Mining Operations
HDH Instruments has worked with mining equipment suppliers and OEMs for many years. Our team supports those building and servicing machines used in mineral extraction, exploration, and coring applications. Projects include large shafts, drill collars, drill rods, and components used in blasting and boring rigs.
Every part is machined at our Texas facility, which is equipped to manage long materials, large diameters, and heavy loads. Whether it’s a single large-diameter shaft or hundreds of precision tubes, our team delivers reliable machining to meet demanding timelines.
Deep Hole Drilling for Structural and Drilling Equipment
Deep hole drilling is often needed in mining, where parts such as drill string tools, directional boring equipment, or hydraulic actuators must operate at extreme depths. HDH uses specialized machines to bore precise internal holes through long bars and heavy-walled tubing. Our capabilities handle both ferrous and non-ferrous alloys, including high-strength steels used in high-impact environments.
These deep bores are used in drill collars, stabilizers, and pressure sleeves—anywhere that consistent internal geometry is required across several feet of length. Our experience in long-part handling keeps runout low and repeatability high.
Honing for Wear Surfaces and Hydraulic Fit
Surface finish plays a major role in sealing, wear resistance, and pressure control. Honing provides the internal polish and dimensional consistency needed for hydraulic cylinder tubes, pump housings, and bearing sleeves used in mining machines.
Our horizontal and vertical honing equipment can accommodate large bores and extended lengths. This service is frequently used on parts that require tight diameter tolerances and high-quality finishes to reduce friction and maintain performance over long duty cycles.
Tube Boring for Heavy-Duty Components
Tube boring is used on thick-walled pipes and structural tubing found throughout mining equipment. HDH machines straight, concentric bores for parts that must carry heavy loads or withstand high-pressure fluid systems.
This process supports the creation of reliable parts for reverse circulation drilling and downhole assemblies. Our machines are built for long parts, and we routinely handle tubes up to 45 feet long and diameters up to 14 inches.
Heavy Material Handling and Volume Capability
Mining projects often involve large, heavy components. Our facility includes lathes, presses, and boring machines built for that size and scale. We offer sawing, turning, drilling, honing, and straightening all under one roof, reducing handling time and improving delivery consistency.
We also operate a company fleet for pickup and delivery throughout the Greater Houston area, with shipping options for clients across the country.
