Large Machining
Capability of large machining
Puwin has the capabilities to deliver high-quality, oversized parts tailored to diverse industrial needs. Our production strength is anchored by advanced machining equipment: we have invested in state-of-the-art OKUMA and SNK CNC gantry (bridge) machining centers, which are renowned globally for their stability, efficiency, and precision in heavy-duty processing. These machines feature an expansive working envelope, providing ample space to handle large workpieces while maintaining consistent performance throughout the machining process.
We can produce large-scale parts with a maximum size of up to 2000mm and a weight limit of under 2 tons，catering to the demands of sectors such as wood products industry, heavy machinery, and energy, where oversized components are critical. Beyond size and weight capacity, we prioritize precision as a core competitive advantage: our machining processes can be controlled within an tolerance of ±0.02mm. This level of precision ensures that every part we manufacture meets strict dimensional standards, reduces assembly errors, and enhances the overall reliability of our clients’ end products. Whether for one-off prototypes or high-volume production runs, Puwin’s large machining capabilities are well-equipped to meet your specific needs.
Application of large machining parts
Large machining parts, with their substantial size, high precision, and robust performance, serve as the backbone of numerous key industries, underpinning the operation of critical equipment and large-scale projects. Their unique ability to meet the demands of heavy-duty, high-stability scenarios makes them indispensable in modern industrial production.
Wood products industry
Large machining parts play an equally critical role in the wood products industry, especially when handling large, heavy wood materials，large machining parts bridge the gap between raw lumber and high-quality finished products.
A key application lies in wood processing equipment manufacturing. Core machinery like chipping heads, chipping knife, planer heads, large-scale panel saws, wide-belt sanders, and multi-axis wood routers rely on oversized machining components to function smoothly.
Energy industry
In the energy sector, large machining parts play a vital role in both traditional and renewable energy infrastructure. For thermal power plants, oversized turbine casings and generator rotors，ensure efficient energy conversion by withstanding high temperatures and rotational forces. In wind energy, massive hub components and main shafts, often exceeding 1500mm in size and weighing over a ton, connect wind turbine blades to generators, requiring ultra-precise machining to maintain stable rotation and maximize energy capture. These parts’ durability directly impacts the lifespan and efficiency of energy facilities.
Heavy machinery and construction
In heavy machinery and construction, large machining parts enable the operation of equipment like excavators, cranes, and bulldozers. For example, the large boom cylinders and chassis frames of construction cranes. Oversized conveyor rollers and crusher housings in mining.
