山德维克日本分公司与立石电机公司联合研制了一种“可乐满台式电子计算机”,已于两年前问世.为了进一步提高性能,最近又研制了一种新的薄形台式电子计算机.一般的台式计算机,通常可进行四则、常数、乘幂、倒数、平方根等计算;用在车削和铣削两种加工领域中,可计算切削速度、主轴转数、所需功率、每齿走刀量、排屑量等14个项目.经过改进的新型台式计算机,除能进行上述各种计算外,还增加了加工时间、工件单位面积上的切削力、平均切屑厚度等9个专用键,并可用于钻孔加工的计算.在车、铣、(?)三个加工领域中,共可进行27种计算.另外,这种计算机上还附有划线键、公制与英制换算键.例如欲求切削速度(V)220米/分、工件直径(D)35毫米的车削加工中的主轴转数(n)时,不必依靠复杂的公式运算,只要摁动专用键V、D、n 和送进220、35,即可迅速求出主轴转数.该机尺寸为74(横)x12(纵)×9毫米(厚),重90克,小形轻便,使用灵活.
Sandvik Japan and Hitachi Electric co-developed a “Coke-Man desktop computer,” which came out two years ago, and recently developed a new, thin desktop computer to further improve performance. General desktop computer, usually can be four, constant, power, reciprocal, square root and other calculations; used in turning and milling two processing areas, can calculate the cutting speed, spindle rotation, the required power, , The amount of chip discharge 14 projects.An improved new desktop computer, in addition to the above calculations, but also increased the processing time, the workpiece per unit area of the cutting force, the average chip thickness and other nine dedicated keys, and is available In drilling, milling, (?) Three processing areas, a total of 27 kinds of calculations can be carried out. In addition, this computer is also attached to the scribing keys, metric and English conversion keys. For example, to cut The speed (V) of 220 m / min, the diameter of the workpiece (D) of 35 mm turning process spindle (n), do not have to rely on complex formulas, as long as the special keys to move V, D, n and 220 , 35, you can quickly find the spindle rotation The machine size is 74 (horizontal) X12 (vertical) × 9 mm (thickness), weight 90 g, Small lightweight, and flexible.
