Custom brush for dealing with step differences and irregular gaps.

basic information

In machine tools, necessary gaps are created according to the movement of movable parts and the cover structure. However, gaps that include steps or irregular shapes tend to have uneven contact conditions, making sealing difficult. This product is a custom brush designed to accommodate such stepped shapes. The brush has flexibility and the ability to conform to gaps, but for sealing applications in machine tools, additional processing of the bristle tips (adjustment of cut shapes) is performed to match the steps. This ensures appropriate contact conditions even against variations in height and uneven gaps, suppressing the intrusion of chips, dust, and coolant mist, as well as the diffusion from inside the equipment. For stepped structures and movable parts that are difficult to address with rigid sealing materials, stable sealing performance is achieved through brush designs tailored to the shapes. At Kyoshin Giken, we manufacture brushes that accommodate complex stepped structures through custom designs and bristle tip processing, and we have numerous adoption records with machine tool manufacturers.
