美國(guó)進(jìn)口EXTEC品牌Labcut 250B型臺(tái)式金剛砂切割機(jī)

●一般特點(diǎn)：

1)臺(tái)式，手動(dòng)操作，切割飛輪直徑zui大為10 inch (254mm)，可用于切割以下材料：

硬質(zhì)鋼；工具鋼；鑄鐵；鋼和鎳合金；

非鐵金屬，如鋁、銅、鈦等；

陶瓷；玻璃；復(fù)合材料；

硬金屬如碳鋼；

也可切割桿條和管子；

2)金剛砂飛輪間接地由3相4 HP (3 KW)馬達(dá)驅(qū)動(dòng)，轉(zhuǎn)速為3900rpm?？蛇x配滑車和皮帶裝置來(lái)改變切割速度。為了提升或降低切割頭，1個(gè)探位器被放在蓋子的一邊。1個(gè)制動(dòng)缸與升降探位器配合，因此切割非常好控制；

3)該機(jī)器床為T型槽基座，由虎頭鉗固定。標(biāo)準(zhǔn)儀器提供左、右邊的快速虎頭鉗，容量為2 ? inch (64mm)。樣品材料的兩邊被夾子緊緊夾住以確保zui小的毛刺。非常長(zhǎng)的樣品，可通過(guò)兩邊的頂蓋的孔輕松操作；

4)1個(gè)17 L的55L/min的泵循環(huán)將液體送到旋轉(zhuǎn)飛輪的兩邊，并流經(jīng)工作區(qū)域。如果須要干式的切割，則可停止制冷循環(huán)。該制冷循環(huán)也可用作清洗功能。在儀器的前面進(jìn)行操作控制；

5)在控制板后面的櫥柜里放有電子元件。前面面板通過(guò)24V回路控制，滿足嚴(yán)格的安全要求。前面面板上有切割頭馬達(dá)開(kāi)/關(guān)，制冷泵開(kāi)/關(guān)，內(nèi)部燈光開(kāi)關(guān)。該儀器設(shè)計(jì)時(shí)已考慮操作者的安全。1個(gè)定時(shí)安全開(kāi)關(guān)能在切割飛輪仍在旋轉(zhuǎn)時(shí)防止蓋子打開(kāi)；

●技術(shù)特點(diǎn)：

1)馬達(dá)：4 HP (3KW) 3相馬達(dá)；

2)主軸直徑：zui大為1 1/4 inch (32mm)；

3)飛輪轉(zhuǎn)速：標(biāo)準(zhǔn)3900 rpm；

4)飛輪尺寸：zui大直徑為10 inch (254mm)，也可放小的飛輪；

5)尺寸WDH：512×685×620 mm；

6)重量：80Kg；

Extec's Labcut 250B is a bench-top, manually operated abrasive cutting machine designed for cutting wheels up to 10 inch (254mm) diameter. The Labcut 250B can be used to section a wide variety of modern materials including:

• Hard Steels
• Tool Steels
• Cast Iron
• Steel and Nickel Alloys
• Non-ferrous Metals eg. Aluminum, Brass, Titanium
• Ceramics
• Glass
• Composite Materials
• Hard metals e.g. Carbides
• The Labcut 250 also cuts bar and tube

The abrasive cutting wheel is indirectly driven at 3900 rpm using a 3-phase 4 HP (3 kW) motor. An optional pulley and belt set is available for changing cutting speeds. To raise and lower the cutting head, a lever is located at the side of the canopy. A hydrocheck is fitted to the raise/lower lever so that cutting can be carried out in a smooth manner.

The machine bed is a T-slot base on which the vises are mounted. The standard machine is supplied with right hand and left hand quick action vises having 2 ½ inch (64mm) capacity. The material is clamped on either side of the cut ensuring minimum burr. Long lengths of material can be easily handled using access ports on both sides of the canopy.

A 4.4-gallon (17 l) with 55-liter/min pump circulates fluid on both sides of the rotating wheel and floods the work area. If dry cutting is required, the coolant circulation can be stopped. The coolant circulation system can also be used as a wash down facility; suitable controls for this are located on the front panel.

The electrical components are housed in a closed cabinet located behind the control panel. The front panel switching is via 24 V control circuits and therefore complies with even the most rigorous safety codes. Front panel controls include cutting head motor on/off , coolant pump on/off and internal light switch. The Labcut 250B has been designed with operator safety in mind. A timed safety switch prevents the canopy from being opened while the cutting wheel is rotating.
