Hello!
The problem in next:
Machine frezernyy with workers battlefields 2050 • 3050mm with liquid ring vacuum table. When harvesting a small, either carved details a small size, under frezerovanii, for example plexiglas, on big speed applying details not go and their has her slicing up frezoy (blowers with itself shavings upward). Downforce hoisted there is no. Could you tell me, share experience as stowed, or what still deceptions there are?

For several millimeters until the end of cut slowed submission until 50-100mm / shadowing (vpisyval manually F50ili F100). All details remained on place as plastic so and plywood 2-4mm. Mentor nothing not krepil and not, with rubber cement.

Recently saw video on which clearly arrived in my the most the right work, under cutting details Edgar Froese around the circle pripodnimalas and left it small bridges, several units been lacking to detail not try to move too much, and after the end of the operator simply but instead to knife throw on Bridge (ship) and melle detail. Simply and is logical.

Can I and the original of the, but, to example, pilyastru 2000's 80 mm no vacuum not deterred, shrugs off its. And here is couple of tiles two-way scotch plus prizhim with laterally help. This from practice.

but perhaps easier move the text who had given their lives leaf filled molds (that's fizzing not will, as under fur. Securing) and on him already Velcro gears and springs informed me that?

And who had given their lives leaf constantly lies on vacuum table (leaf orgalita 3 mm). As without him?

From the looks of it. Bridges in UE, compression blowers, blowers -struzhka down. And the latest variant- monkey (he same operator press) suyuschaya fingers in zone processing with goal retaining)
Text or. The last most widespread (

Accounted for jurisprudence as all from listed options. The most remarkable this option with a monkey right (pity only fingers)
Very account for often cut Triangular from plexiglas 2 mm on information stands and etc. Vystovochnuyu products. Sizes editions such, that with postobrabotkoy is the not want be bothered. Seceded from situation the next way:
1. 's a compilation of details on page material thus, to between details remained just a narrow striped material 1-2mm;
2. Choose particularly opportune option "order processing";
3. Determine "primary point" on trajectory thus, to the switching the assistant trajectory cut off up a blank from whole leaf.
The Plexiglas until 3 mm, I'm cutting direct filum frezoy with diameter of equal or less thickness material, steel wool remains in material and not gives replicator patterns on the walls are moving in (just use vakuumnymnym table)
Thus same way vysekayu from liovogo PVC 3 mm huge exhorts-in nomerkov, and other small beer.

Not bad, but leave (as on my taste of) - under zadevanii mounts frezoy on speed processing tree of - might negatively affect the integrity not thick such. I itself made from beech, 10 mm - the thickness of the, 30 - width, holds well, couple of times been bailed out not in is place - sfrezerovyvaet (3-4 graph) and there is no problems. And make some such from waste - not question. Can be and a thicker cut, only quarter-under stocking do.

Incidentally, arose the need cut into snowflakes from delicate of plastic (0.15 mm) and from paper, blowers 0.8mm.
There is whether ways duct-tape that to table the same paper, without vacuum? ???? need to zatsep was across Square, otherwise blowers raises leaf on the incision.

Accounted for to do big model from plywood altitude 150-200mm, dimensions until 400kh500mm (more worker move press not allowed) on obrabatyvayuschem the center of the (machine designed for processing have become). The table have him from longest with gives-type and connected.
Did so. , with rubber cement from several sheets plywood stocking. When has dried out, with rubber cement its to large liner plywood, size of in the entire the table, but not simply so, and through a newspaper. In this page drilled 4 holes through which krepil all of this agriculture to table with the help gives-shaped pazov. Under processing nothing not takes flight, not is detached. When all is prepared, then couple of strikes a hammer on stameske in seams, between model and the latest sheets plywood (who through a newspaper it's glued down) and model is separated from already of an unnecessary podlozhechnogo leaf plywood. Glue - the gelva, Import (accurately not remember what).

I so securing templates from MDF, when goes word processing with tenderloin on draw an outline within. Sacrificial chamber bottom layer, too, from MDF. Bond simple wrapping. Glue D3 Rakol. Only I breed his until autogeneous liquid sour cream, to he easily was applied soft brush. 3-4 hours on season and in work. Such fastening very works well on shift, but on gap ” existed effort is determined by durability paper. Only glue need crippling on a minimum, to bond not got soaked, otherwise the trouble - not distract the. Another moment, if there is subtler statist tracts of terrain their need cautiously separate. MDF not is durable. I'm using thin knife.

Caveats mentioned here Togglami can be keep one finger in and small billets, but only with "interval of" from Central sognutoy stretch of have become. The entire the question is, that under tore off his such a zigzag section seams flat give (type slice the copy of or couples screws), and further keep one finger in already Togglami or have several "zigzags" (that, too, not in a bummer, and is done in slesarnykh narrow even not for minutes).

For serial milling except nursing on the sides wise produce a pattern, for example from plywood, which means from above on entire stocking and is pressed / he's welshing. In template most frezoy vyfrezerovat the contours of to badly blowers freely proceeded. If size the table and press allow, then one side can be stowed, through hinges.

Да я использовал готовые болты, диаметр сейчас точно не могу вспомнить, кажется 6 мм (возможно 8мм) там по чертетежу
должно быть понятно. Делал давно, просто из любопытства. Вырезал несколько штук, в работе по серьезному
не использовал, не понадобилось. Проверил, что конструкция работает и позже отдал в подарок.

Может кому будет интересно. Вот как я креплю заготовки к столу с боковым упором который со смещенным центром. Стол фанера 10 мм в два слоя с просверленными отверствиями и нарезанной резьбой М8.

Резьба в фанеерке - больно ненадёжно. Нужно использовать футорки от мебельного крепежа 6х13 и вкручивать их в нужных местах постепенно, по мере надобности. Толщину фанеры лучше увеличить до 15 мм, чтобы можно было футорки накрутить с приглублением от поверхности стола.

Это мой вариант крепления заготовки

Прижима заготовки сверху не наблюдается в данном случае, а это значит, что заготовка снизу должна быть идеально плоской, а то фреза может "косануть" на горизонтали и хрупнуть (было).
1,5-2 мм стальная лапка уголком свободно устраняет такое. А на удержание заготовки на месте шикарно работают эксцентрики из 67 поста - быстро, просто, крепко.

У меня лежит лист МДФ 19мм, прям в него саморезами вхирачиваюсь.

Это самый простой и отважный способ крепления. Почти не нужно метиться, шуриком шурупы или саморезы просто "залетают". Тем же шуриком можно и проходные дырки в заготовке сделать.
Минусы: головки при закручивании посильнее часто срываются, посему нужен кулёк шурупов или саморезов, а тут и второй "минус" - у них должна быть разная длина поскольку крутятся-то они только к жертвенному столу максимально на его толщину, а закрепляемые детали в жизни встречаются разнотолщинные. Т.е. до полтоса мм толщины всё получается, а толще придётся уже мудрить с заглублениями под шляпки вглубь материала, да ещё до нужной для имеющейся длинны шурупа-самореза.
Ну и сложно выглядит жертвенный стол на станках больших форматов, где желательна фанера (или что другое подходящее - доски, например) потолще, чтобы можно было торцевой фрезой выровнять стол по постоянному уровню - операция, прямо скажем, плёвая, но очень многие ей пренебрегают, а потом "торчат" на мелочных затыках из-за этого.

Недавно видел видео на котором четко просматривается по моему самая правильная работа, при вырезании деталей фрезе по кругу приподнималась и оставляла небольшие мостики, несколько штук  хватало чтобы деталь не шевелилась, а после окончания оператор просто прошелся ножем по мостиках и вынул детальку. просто и логично.


Я заготовку шурупами к жертвенному столу, а потом мостики в УП от 4 до 8 шт, длинна 3 мм, высота 2-3 мм

На фрезере креплю саморезами к жертвенному столу из фанеры 24 ки в свободных местах, изначально отдельно прогоняю программу с разметкой.

А вот на лазере приходится изголятся.  из-за того что обычно рабораю с 1500Х750 листами, а поле 1200Х800 то там 2 направляющие  на всю длину , чтоб край на свисал, спереди крепится на зажимы фанерные  п-образные, ну и грузы разнообразной массы и размера...

может быть конечно "америку открою", но все же поделюсь маленьким "ноу-хау", вдруг кто не в курсе... ;)  для удобства размещения заготовок сделал на жертвенном столе V-фрезой "сеточку" с шагом 5-1 см (5см -- чуть глубже, 1см -- чуть мельче), причем узлы/линии сетки совпадают с соответствующими хардварными координатами станка. удобство заключается в отсутвии необходимости выставлять 0 по XY -- выставляем угол заготовки по узлу сетки и загоняем шпиндель в известные координаты. мне -- удобно. :)

Очень правильно!
Я делаю аналогично, но проще: после принудительного выравнивания уже закреплённого жертвенного стола просто наношу разметочный крест, линии которого и считаю базовыми для дальнейших операций.
