Surface and Unground Mining Environments

The mining industry demands absolute reliability under the most punishing conditions on Earth. Equipment faces relentless abrasive wear, extreme impact loads, and corrosive underground environments every single day. When a critical component fails on a dragline, continuous miner, or haul truck, the resulting downtime can cost thousands of dollars per minute.

At Greno Industries, we specialize in heavy-duty, high-precision CNC machining and custom manufacturing for the global mining sector. From reverse-engineering legacy equipment parts to manufacturing massive, high-tolerance OEM components, we deliver the durability and structural integrity required to keep your extraction and processing operations moving.

Our Core Manufacturing Capabilities for the Mining Sector

Our state-of-the-art facility features large-envelope CNC milling, turning, and multi-axis machining capabilities. We are fully equipped to handle both complex geometries and massive, heavy-weight raw materials.

Custom Component Manufacturing

We manufacture a comprehensive range of replacement and OEM mining parts, including:

  • Drive shafts, splines, and heavy-duty axles

  • Pinions, gears, and planetary gear assemblies

  • Hydraulic cylinder components, rods, and gland nuts

  • Crusher jaw toggles, eccentric shafts, and wear plates

  • Custom bushings, seals, and high-load bearings

  • Sheaves, pulleys, and hoist components for draglines and shovels

Large-Envelope CNC Milling & Turning

Heavy mining equipment requires large-scale machining capacity. Our robust infrastructure allows us to mill and turn heavy-gauge forgings, castings, and bar stock to incredibly tight tolerances, ensuring flawless drop-in fitment during field installation.

Stress Relieving & Non-Destructive Testing (NDT)

A mining part is only as good as its structural integrity. To ensure our parts endure continuous cyclic loading, we offer stress-relieving processes alongside comprehensive inspection options, including Magnetic Particle Testing (MT) and Liquid Penetrant Testing (PT), to catch any microscopic flaws before parts leave our floor.

Why Partner with Greno Industries?

Advanced Reverse-Engineering

Mining operations frequently utilize aging equipment fleets where original OEM parts are either discontinued, prohibitively expensive, or backed up by months-long lead times. Our engineering team can reverse-engineer worn or broken components, creating precise digital models and manufacturing replacement parts that often exceed original performance specifications.

Certified Quality Management

Our facility maintains a rigorous quality assurance program. Every mining component undergoes stringent dimensional inspection utilizing advanced metrology equipment, ensuring absolute adherence to your engineering drawings and material certifications.

Rapid Turnaround to Minimize Downtime

We understand that supply chain delays directly impact your tons-per-hour metrics. By optimizing our machining schedules, maintaining strong relationships with heavy material suppliers, and executing internal efficiencies, we help you get critical machinery back online swiftly.

Metals for Maximum Impact and Wear Resistance

Mining machinery parts must possess exceptional yield strength, toughness, and wear life. Greno Industries works with a robust selection of heavy industrial metals and specialized materials, including:

  • High-Strength Low-Alloy (HSLA) Steels: Ideal for heavy structural components requiring excellent load-bearing capacity and weldability.

  • Abrasion-Resistant (AR) Plate & Hardox: Utilized for liners, chutes, and buckets that experience continuous friction and material impact.

  • Alloy Steels (4140, 4340, 8620): Heat-treated to precise specifications to provide the optimal balance of core toughness and surface hardness for gears and shafts.

  • Stainless Steels & Nickel Alloys: For corrosive environments, such as acid mine drainage or chemical processing installations.

  • Bronze & Brass Alloys: Precision-machined for high-wear bushings, thrust washers, and bearings essential to heavy rotating machinery.

Upgrade Your Mining Equipment Reliability

Whether you need a single critical shaft replacement for an underground boring machine or a reliable manufacturing partner for a high-volume run of surface mining wear parts, Greno Industries has the equipment, experience, and scale to deliver.
