Proven Performance Across Critical Mining Applications
Our Mining Ground Spiral Bevel Gears are trusted across the mining industry for critical power transmission applications. In underground conveyor drives, they provide reliable right-angle power with uniform load distribution and reduced vibration. For primary and secondary crushers, the optimized root fillet geometry delivers exceptional impact fatigue resistance against severe shock loads. In SAG, AG, and ball mill drives, smooth rolling engagement minimizes bearing stress and enables extended overhaul intervals under continuous 24/7 operation. Surface mining equipment—including electric shovels, draglines, and excavators—relies on these gears for swing and propel drives that withstand continuous high-torque reversals and massive digging loads without micro-pitting or premature failure.

Forging
When gears need high performance that needs to withstand high loads, high stress, impact loads or fatigue loads, forgings are suggested to use. Forging allows metal fibers to be continuously distributed along the gear profile, significantly improving root strength and fatigue life.
Turning
This is the process of cutting and shaping solid materials into precise parts. It uses tools like lathes, mills, and drills to remove excess material. Machining transforms a simple block of metal into a finished, functional component.
Gear Milling
Gear Milling is a gear cutting process that used a rotating from cutter shaped to match the exact space between two gear teeth is plunged into the gear blank. After cutting one tooth space, the blank is indexed to the next position .
Heat Treatment
Gears need to be running with two gears or above two gears, that makes them easy to be worn-out. That’s why most types of gears need to be harden through heat treatment.
ID & OD Grinding
ID grinding, OD grinding, Surface grinding are all belonging to CNC grinding which are the foundational precision abrasive machining processes used to achieve exceptional dimensional accuracy and surface finishes, especially on hardened materials.
Tooth Grinding
Tooth Grinding are the final processes are applied after heat treatment to correct distortion, improve geometry, and achieve the final surface finish necessary for quiet, efficient power transmission.
