I want to design a fixture to hold multiple cylindrical metal workpieces of diameter 8 mm and length 30 mm. The workpieces must flush with the top surface of the fixture. I need to use it to coat multiple workpieces with wet film applicator which will be later subjected to sliding wear tests. I am thinking of two rectangular surface , one surface with holes and the other with slots , so that the workpieces can fit in. The surfaces will be held by four pillars and there must be some mechanism to hold or secure the workpieces tightly.
@Sebastian. I want the diameter to be coated. Basically I want to test the sliding wear resistance of a coating material using pin on disc wear machine, wherein 8 × 30 mm Pin is the specimen and circular and wider counterface is the disc. I what to coat the Pin with the coating material, but with the film applicator I have I an only coat flat and rectangular specimen of width 110 mm. Therefore, I was thinking of designing a fixture with the top surface containing holes to hold many Pins of diameter 8mm , so that using film applicator I would be able to coat multiple specimen which would be ejected out later once the coating gets cured.
Yes definitely a fixture can be designed to hold multi cylinderical metal pieces. But the orientation and dimensions of the the metal pieces will play a vital role on how and what type if fixture one needs to be developed..
