  Introduction The   patented adjustable gap system of the VA series enables a precision of 0.05mm. This unique setting of the gap between the disc and the ring of barrel make super fine polishing granulate to be possibly used as media. The VA series model therefore produces the superior polishing surface with lowest processing cost. Besides, the customized process prevents the gap from overheating.   Working principal The VA series machine from Humo work on the centrifugal disc finishing concept, it functioned with highly effective and efficient mass finishing system. During this process, the components are processing in a barrel shaped container where media and components make rotational relative movement. The media inside the container is driven by centrifugal force of disc which generated from the bottom of the container. The disc is separated from the container wall by an adjustable gap where the water is flowing though in the wet processing machine. In dry processing machine for fine polishing, however, the gap is there for disc rotating. The centrifugal force with different media act on surface of component gives different finishing resul, which will offer at least 20 times high productivity compared with vibratory finishing process. During wet surface finishing processing a constant water and compound flow which at meantime take off wear off debris together. This leaves the components a fresh and clean surface.   Application Suitable for small to medium size production capacity, especially suitable for flexible production with small batch multi category production   Feature Lower capital investment compared with CF ZERO gap machine model The system model can be customized according to customer requirement Better cost effective High efficient machine design with already in hand experience and process Superior surface finishing    Product Pictures       Production Process      Customer Processing Scheme     Company Information   Zhejiang Humo Polishing Grinder Manufacture Co., Ltd. established in 1970s is one of the formulators of surface finishing industry China’s National Standards.

Mass Finishing and determination of Process Capability allows you to use the right media to ensure consistent production capability and built-in reproducibility of your manufacturing processes. We will work with you to determine the best media and the best processes for your parts. This step can result in: Reduced Cycle Times Improved RMS Finishes Reduced Finishing Costs Access to Latest Technology R & D for Special Process Media   Mass Finishing describes a mechanical process where large amounts of parts are economically processed to achieve one or several surface improvement functions. These surface improvement functions include:   Cleaning Deburring Surface refinement Inhibiting Drying 

These functions are not independent of each other. It is common to have several or all of these functions take place in a single mass finishing process.
Process Capability is the measured, built-in reproducibility of the product turned out by the process. Such a determination is made using statistical data, not wishful thinking. Statistically determined limits are compared to specification limits to decide if a process can consistently produce acceptable product. Process capability is best established through closely monitored testing and recording of data over a set period of actually production.
