Precision Machined Parts for Mining and Heavy Equipment
ORRCO produces precision machined parts for mining and heavy equipment applications, with over 80 years of experience delivering durable, tight-tolerance components that perform in the industry’s most demanding environments. From coal mining bit bodies to hydraulic valves and fluid control components, we machine the critical parts that keep heavy equipment and mining operations running.
Coal Mining Bit Bodies
One of ORRCO’s core specialties is machining steel bit bodies for the coal mining industry. These components are precision-machined to accept carbide tips that customers braze in place. Our custom rotary machinery supports high-volume production runs with the dimensional consistency that coal mining operations depend on — every bit body machined to the same exacting specifications, run after run.
Coal mining bit bodies must withstand extreme impact, abrasion, and torque. ORRCO machines these components from high-strength steel alloys with the tight tolerances required for proper carbide tip seating and secure retention under load.
Hydraulic and Industrial Valves for Heavy Equipment
Heavy equipment — excavators, loaders, bulldozers, and mining machinery — relies on hydraulic systems to power movement and control. ORRCO machines hydraulic valves, valve bodies, and fluid control components used in these demanding applications.
We produce:
- Hydraulic valve bodies and housings
- Valve spools and sleeves
- Industrial control valves
- Custom fluid control components
- Hose fittings and connectors
Our CNC mill-turn capability is particularly well-suited to valve components that require precise internal bores, cross-drilled ports, and complex external geometry — all produced complete in a single setup to ensure concentricity and dimensional accuracy.
Wear Parts and Durable Components
Mining and heavy equipment operate in environments where wear, impact, and contamination are constant. Components fail not because of poor design, but because they weren’t machined to the right tolerance or from the right material. ORRCO works with customers to machine wear-resistant components including:
- Bushings and wear sleeves
- Pins and fasteners
- Structural components
- Cylinder components
- Custom hardware
Materials for Mining and Heavy Equipment
ORRCO machines precision parts for mining and heavy equipment from materials selected for durability, strength, and wear resistance:
- Steel and Alloy Steel — high-strength structural and wear applications
- Stainless Steel — corrosion-resistant hydraulic and fluid handling components
- Brass — fittings, connectors, and fluid control parts
- Aluminum — lightweight housings and structural components
- Carbide-compatible steels — for bit bodies and tool holders
High-Volume Production Capability
Mining operations and heavy equipment OEMs often require large quantities of replacement parts and consumables. ORRCO’s custom rotary machinery is built for this kind of work — delivering thousands of identical components per run with the repeatability and consistency your supply chain depends on.
We work with OEM procurement teams and aftermarket distributors to establish reliable supply arrangements for high-usage components, helping you maintain inventory levels and avoid costly equipment downtime.
Quality and Traceability
Every component we produce for mining and heavy equipment applications goes through dimensional inspection before shipment. Our ISO 9001:2015 certified quality system provides full traceability from raw material to finished part, with dimensional reports available on request.
Why Mining and Heavy Equipment Manufacturers Choose ORRCO
When equipment goes down in a mine or on a construction site, every hour of downtime is costly. That’s why mining and heavy equipment manufacturers need a machining partner they can count on for consistent quality, reliable delivery, and responsive communication.
ORRCO has been that partner for decades — delivering precision machined parts for mining and heavy equipment applications on time and to spec, every time. Our experience with coal mining bit bodies, hydraulic valves, and high-strength wear components gives us the process knowledge to handle the parts that matter most to your operation.
