美国进口EXTEC品牌Labcut 250B型台式金刚砂切割机

●一般特点：

1)台式，手动操作，切割飞轮直径zui大为10 inch (254mm)，可用于切割以下材料：

硬质钢；工具钢；铸铁；钢和镍合金；

非铁金属，如铝、铜、钛等；

陶瓷；玻璃；复合材料；

硬金属如碳钢；

也可切割杆条和管子；

2)金刚砂飞轮间接地由3相4 HP (3 KW)马达驱动，转速为3900rpm。可选配滑车和皮带装置来改变切割速度。为了提升或降低切割头，1个探位器被放在盖子的一边。1个制动缸与升降探位器配合，因此切割非常好控制；

3)该机器床为T型槽基座，由虎头钳固定。标准仪器提供左、右边的快速虎头钳，容量为2 ? inch (64mm)。样品材料的两边被夹子紧紧夹住以确保zui小的毛刺。非常长的样品，可通过两边的顶盖的孔轻松操作；

4)1个17 L的55L/min的泵循环将液体送到旋转飞轮的两边，并流经工作区域。如果须要干式的切割，则可停止制冷循环。该制冷循环也可用作清洗功能。在仪器的前面进行操作控制；

5)在控制板后面的橱柜里放有电子元件。前面面板通过24V回路控制，满足严格的安全要求。前面面板上有切割头马达开/关，制冷泵开/关，内部灯光开关。该仪器设计时已考虑操作者的安全。1个定时安全开关能在切割飞轮仍在旋转时防止盖子打开；

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.
