OEM Case Studies

A European bearing OEM was sourcing outer rings from a machine shop that cut them from solid bar stock, resulting in a high steel waste percentage (45% scrap rate) and high unit costs.

We transitioned the component development to our CNC radial-axial ring rolling line. The preform is punched out and rolled, eliminating the need to bore out the center material.

Forged in chrome bearing steel SAE 52100, spheroidize annealed in controlled furnaces, and rough-turned to 0.5mm grinding allowance in-house.

Reduced raw material steel waste from 45% down to 12%, achieving an overall unit cost saving of 22% for the customer.

An Indian tractor manufacturer was experiencing tooth distortion and cracking issues on transmission gear blanks after final gas carburizing, leading to assembly-line rejects.

Our metallurgy team determined the forging grain structure was inconsistent. We redesigned the closed-die hammer tools and introduced isothermal annealing heat treatment.

Forged in 20MnCr5 steel. Implemented computerized die simulation to verify metal flow, followed by precise isothermal furnace cooling cycles.

Isothermal structure eliminated post-heat treatment distortion. Assembly-line reject rate dropped from 3.2% to absolute 0%.

A heavy machinery vendor needed custom cylinder sleeves. The thick walls required long CNC boring times, creating supply bottlenecks for their assembly plant.

We developed an upset closed-die forging process that punches out the internal bore shape during the hot forging stage itself, leaving a near-net component.

Forged in EN19 high-tensile alloy steel. Machined on our high-power CNC lathes with automatic boring bars to final dimension tolerances (+/- 15 microns).

Reduced OEM customer's turning/boring machining cycle times by 60%, speeding up their supply line by 3x.
