The gearbox housing is the cover of the power transmission system of agricultural machinery. It is made of ductile iron with excellent material properties. The precision and shape tolerance after machining must meet the requirements of the customer's drawing.
The swash plate of the oil pump has strict requirements on the size, which is not able to be done by ordinary cutting centers. To meet the customer's drawing requirements, hardness enhanced by heat treatment, and grinding process are necessary in the process. Non-contact measurement will be used on partial holes to cover where three dimensional measurements can’t do.
Exhaust gas manifold, EGR (Exhaust Gas Recirculation) body, or automotive secondary intake manifold, secondary exhaust gas upper manifold. The partial product shape and size is shaped by gravity casting aluminum alloy. The aluminum alloy workpiece by gravity casting has stable quality. This makes castings with high precision dimensions and finer surface roughness, which can reduce the range of machining. The exhaust gas manifold is used to guide the exhaust gas back to the intake manifold, making it inhaled and burned by the engine again. Product properties should have high temperature resistance and vibration resistance. The dimension and shape tolerance is required to be below 15μm, and the surface roughness is required to be below Ra1.6.

WKPT is the only one supplier of wind turbine brake cylinders in Taiwan. The material selection of wind turbine components is rather strict; the wind turbine brake system is made of ductile iron material with better low temperature impact resistance than EN-GJS-LT, which can still work even at temperatures far below 0°C. In addition, the workpiece is heavy so it needs to be processed by large-scale machining equipment. The size requirement of workpiece is strict and has long and deep holes, so it needs to be machined with special tools.
The partial product shape and size is finished by aluminum alloy of gravity casting. The aluminum alloy workpiece by gravity casting has stable quality. This makes castings with high precision dimensions and finer surface roughness, which can reduce the range of machining. The spindle bracket of PCB punching machine has strict size requirement: dimensional tolerance less than 10μm; shape tolerance less than 15μm; surface roughness less than Ra 1.6. The workpiece production is assembled with the upper and lower seats upon special customization.
After multiple tests by the development team, mass production will be begun after the quality is confirmed by the customer. Since the product requires high mechanical properties, including tensile strength and hardness, the manufacturing process is set aluminum alloy blocks for full engraving, which also increases the difficulty of processing and process time. In addition, at least two or more machine tools are used in the manufacturing process for multi-axis machining, and the product size is prone to deviate due to deformation during the cutting process. Therefore, it is necessary to adjust the machining procedure to reserve the machining amount, and refine in the final stage to ensure that the final product meets the requirements of dimensional tolerance and shape tolerance.
Gearbox spindle is used in high temperatures and harsh environments, and the properties of the gearbox are stable, so the requirements for material and accuracy are very strict. For the Zero Defect in the automotive industry, WKPT has built the first smart production line of gearbox spindle in Taiwan. IoT digitalization, real-time computing technology like automatic dispatching, parameters and accuracy compensation are imported to improve product line utilization rate and production yield.
Power supply bearing is the friction part which is capable of bearing external force and vibration. So it is necessary
to add other alloy into normal material as casting parts to improve overall mechanical properties.
Besides, casting defects are not allowed, especially on machining.
Construction machinery is used in harsh environments, especially high temperature and high strength resistance to engine flywheel housing. For this kind of product feature, tough material with solid structure is considered for manufacturing. In order to have outstanding assembly quality, there are rigorous demands on the surface of machining and casting. We have high standard checking defects and flatness, as well as surface roughness by controlling the process precisely, to reach accuracy requests.
Construction machinery always works under harsh environments. Its hydraulic system bears the loading of the excavator all-around, so the hydraulic cylinder is considered with high-pressure resistance. Such product properties are suitable for tough ductile cast iron without any casting defects which may leak inside. In order to increase operation stability, standard such as concentricity and surface roughness are strictly applied on machining precision. High precision specs guarantee that all processes are done precisely.
