you could see my pneumatic press earlier i have a lot of work with inlays, so i need good press this press solved many problems i decided to buy also a hydraulic press two reasons. this press is very big - 1600x1300 mm very often i make small inlays - 100x100 mm and it is not convenient to press small inlays in the big press secondly, sometimes even this 8 ton press can't create a large enough pressure for complex inlays
so this is a factory made press with additional plates. are they strong enough? 99% possibility that these plates can hold this pressure they are made of the hot-rolled steel, 30 mm thick the surfaces are polished and fit well each other but the 30 ton pressure is very big this is a huge pressure i think 15 ton is enough for all your tasks do the plates fit each other?
you can press even not flat blanks the upper plate is flexible place the blank in the centre of the plate this is a powder painting hope it will operate well! 15 ton is a common working pressure i have found the place for press by moving the drill press the press was bolted to the floor the press is very weighty - about 260 kg
the pressure power - 30 ton i don't think i will use at the full power, but it is better to have a reserve this a factory made press two hot-rolled steel plates were added the thickness of plates is 30 mm the professionals assured me that this is enough for 30 ton pressure i found a small sapele end grain board and will try to break it very small pressure - about one ton more hard test - long grain piece of purple heart
i am afraid to press further, it is 10 ton pressure oak was completely flattened but purple heart is not destroyed i have to make small inlay well known soviet quality sign there are problems usually with v-inlays the depth of the pocket in the sharp corners equals zero but you can see that the depth on the inlay is not zero there are some unmilled fibres
i think the fibers are deflected to side and the router bit can't mill them the narrow parts prevent deep insert of flat parts the unmilled fibres can't be removed manually i think the only way to make good inlay is putting a large pressure i put the strips of particleboard on the edges i do this for the first time and don't know the result i created the 15 ton pressure, the board became a crackle we will see the result tomorrow the pressure fell down during a night, but a little - about half a ton
it is not a problem, because the first hour of gluing is the most important the milling settings leave about one mm between the board and the base of inlay it is about the same this distance must be the same all around the thick glue line can appear between inlay and pocket, when the pressure is insufficient you don't see it here i don't like this corner. it must be sharp. i think that unmilled fibres expanded the pocket the pressure was 15 ton
maybe it is an excess pressure i have to experiment further
