走刀箱齿轮，看文字资料好像应该有过载保护并有反转？等委员长来揭谜底了
別等我
因為昨天翻譯了一半後發現根本不是在說這台銑床的
所以就偷懶停了下來
即然樓主有點名了
我就繼續吧
翻的不通順請多見諒
AB Arboga Mekaniska Verkstad of Sweden have made, over the years a wide range of products: power shears, press brakes,
AB Arboga Mekaniska Verkstad這個牌子是由瑞典製造,專業生產電剪刀,油壓折床,
eccentric presses, chip crushers, straightening machines, wire-drawing machines tube draw benches, small and miniature
沖床.碎木機.整直機,伸線機.伸管機,小型銑床
milling machines and a very wide range of drills. Their popular EM825 (and later very similar U2508) mill/drill was a
及各種尺寸的鑽床己經有好多年了.他最受歡迎的是em825鑽銑床(類似u2508)
well-made and versatile machine with a geared-head based on the company's similar range of small drills and co-ordinate
這是台作工精細及多功用的機器,適合公司作為小型鑽孔,產品整合及旋臂鑽床的替代品
and radial-arm drilling machines. The machine appears to have superseded two earlier version, the E135, fitted with a
single-speed motor and a 100 to -640 r.p.m. speed range and the next version, the very similar-looking 2-speed motor
E830 with speeds from 80 to 890 r.p.m. Whilst the early models are rare the EM825 was heavily promoted and sold well
in both European and North American markets from the 1950s to late 1970s.
這台機器有兩種板本,E135配有單速馬達,速度範圍100-640轉,E830配有雙速馬達,速度80-890轉,
這兩種型號和比較少見的EM825相比,在1950年到1970年之間.歐洲及北美市場賣的非常的好
Raised and lowered by a crank-operated rack-and-worm mechanism (fitted at the back of the 4"(101.6mm) diameter column)
the swivelling head was equipped with both fine down-feed and a rapid-action drilling quill with 41/2"(114.3mm) of travel.
To keep the head in alignment during vertical movements the rack was ground on both edges and let into the column,
an adjustable gib strip being provided to take up any lateral play that might develop during service. From the centre
of the spindle to the column was 107/16"(265.1mm) and the maximum distance from the spindle face to the table 12"(304.8mm).
The micrometer dials were fitted with vernier graduations to 1/500"(0.051mm).
升降是由搖把及蝸輪所控制(後面裝有4寸的搖把)
並配備了鑽床旋轉手柄,能快速的的下鑽4吋半(114.3MM)的深度
若加上Z軸的行程,最大行程能到 10 7/16吋(265.1MM)
也預留百分表座能夠很簡單的測量到精度0.05MM以下
Either a two-speed 3-phase, or 1-phase 1400/2800 rpm motor could be specified to drive the 8-speed geared head at speeds
of 100, 150, 205, 300, 440, 640, 880, and 1280 rpm. At 2800 r.p.m. the 3-phase motor was rated at 0.9 h.p. and 0.6 h.p. at
1400 r.p.m. A high-speed option was also listed, with the choice of two speed ranges:
a) 100, 205, 250, 440, 510, 885, 1040 and 2080 r.p.m.
b) 100, 205, 345, 440, 695, 885, 1450 and 2900 r.p.m.
無論是原裝的雙速三相馬達或是單相1400/2800 RPM馬達都可以利用齒輪為八種不同速率的變速
2800轉兩極馬達能利用齒輪箱作100，150，205，300，440，640，880和1280等八種不同的轉速
馬達額定功率為0.9馬到0.6馬
若使用三相四極1400轉的馬達
也有兩種齒輪比供客戶選擇
a) 100, 205, 250, 440, 510, 885, 1040 及 2080 轉.
b) 100, 205, 345, 440, 695, 885, 1450 及 2900 轉.
Various sizes of table were available, but the one most commonly found has a working surface of approximately 17.3"(439.42mm) x 9.43"(239.52mm) with 11"(279.4mm) inches
of longitudinal movement and 6.5"（165.1mm） of cross travel. Most seem to have been fitted with ball thrust races on the feed screws and some with ball races where the
shaft passed through the of the casting. An oil-immersed, power-feed gearbox was an option but, being very expensive, is rarely found.
床台的尺寸也可以自由選擇的
最常見的是17.3“（439.42mm）x9.43”（239.52mm）及 11“（279.4mm）三種款式
x軸及y軸行程約6.5吋(165.1mm)
進給手柄均配有推力軸承
軸承座為鑄造
油浸式機頭齒輪箱為選配
價格非常貴且少見
Very heavily built, the head, once tilted over, could be difficult for one person to hold whilst the retaining nut was tightened. Although the vertical position was held
by a locating taper pin, once outside this setting the head was secured by friction alone and on a limited surface area. However, experienced long-term owners report that
this is not a problem and that even under heavy cuts the rigidity of the head is not compromised. At some point in the late 1960s it appears that the original EM825 was
superseded by an interim model, a heavier version with the larger column and table that appeared on the next generation of Arboga millers, the U2508 (the latter also
being built as a copy in Taiwan during the 1970s and 1980s).
頭部是非常的重的,一但角度歪了,單人會很難去調整及鎖緊
雖然垂直度有斜度銷來定位,但一般認為靠小小立柱的磨擦力來維持頭部的角度及垂直度可能不夠
但不用擔心,在60年代後期,使用者的報告裏並沒有發現何角度偏擺的問題
在60年代開始 em825開始被一些新的型號所取代,例如u2508(u2508在70年到80年開始由台灣代工生產),取代了em825
There are one or two details about the spindle that are worth knowing: it was fitted, as standard, with a 3-Morse taper, with a tang knockout but, because the spindle
line was blocked by the motor above, without a draw-bar for holding cutters in the head; instead, a screwed ring on the spindle nose retained a "slotted" washer which
was slipped over the neck of a cutter between its Morse taper shank and the cutting edges. Only one "washer", distance piece and retaining ring were required for the
full-size 3-Morse fitting, but to hold tapers of
No. 2 and 1-Morse in adapter sleeves (and the special drill chuck) a total of five were needed. These items are still available, but very expensive, the parts for the
3 Morse holder alone costing over £240 in 1999. In addition, before a standard "Autolock" chuck can be used in the head, it needs to be modified to accept the retaining
ring and plate; this is, however, an apparently simple matter. If you are going to buy an Arboga, check that the cutter-retaining parts are with the machine, or budget accordingly to buy them.
主軸有一到兩個小細節值得被注意,主軸開始使用標準三號莫氏錐度取代了原來唐氏的設計,因為主軸被上方馬達位置所限制,無法增加頂部拉桿的設計,取而代之的方法是在主軸鼻部增加一個螺絲及一個開口墊片,上住錐度柄及刀具之間溝槽來防止刀具的滑動
這個開口墊片只能安裝莫氏三號柄而己,無法利用變徑套來轉換1號及2號莫氏柄,當然也配有1號及2號莫氏柄的專用墊片及螺絲,但價格非常的貴(1999年售價240英磅,約2400元人民幣)
一些標準的自鎖夾頭若要使用在這台機器上,頭部必須進行修改以便配合原廠的開口墊片規格
這看起來很簡單,佰如果你要打算買Arboga,請先檢查你的刀具和錐度連接部位是否合適,或是準備花大錢去買原裝的吧
Unaccountably (unless they are, perhaps, Russian copies) some machines have their head assemblies made from "mirror-image" casting; this, of course, has the effect of putting
the gear levers on the right-hand side and the quill-feed controls on the left.
很莫名其妙的是,有些機器有不同的主軸型式(也許是俄羅斯的山寨版)
雖然頭部齒輪箱和原廠完全一模一樣
但是齒輪變速裝置跑到右邊,微進給手柄卻跑在左邊去了
Copied by the New Bharat Engineering Works of Pandit Nehru Road, Jamnagar 361-002, India, the EM825 was also sold as the "VM-25 Energy". This model was mounted on a compact
cabinet stand, similar to the original, but with a coolant pump and tank enclosed within the base and a neat, facia-mounted electrical control panel. The Modig company of
Virserum, Sweden, also manufactured a very similar geared-head mill-drill, the UM3508
由印度New Bharat工程公司山寨本版的EM825被改稱為"VM-25 Energy"
這一型的腳座類似原廠設計但較小及緊湊,底座裏頭安裝有冷卻水泵及水箱,原廠也製造了一個非常類似的鑽床 UM3508
Fitted to its maker's stand the Arboga EM825 weighed,
approximately 530 lbs.
連同腳架,EM825重量為530磅(240公斤)
Another interesting Arboga product was the beautifully-built, ingenious
but rarely-seen UM400, a miniature combination machine..
其他Arboga的產品之中,還有一個很漂亮及好玩的UM400多用機床,只是非常少見
Rare table power-feed gearbox. Note the sight-glass oil level window
少見的床台進給齒輪箱,請注意油位指示器 |
