1 CONSTRUCTION

结构

Frame and main structure casted in spheroidal graphite cast iron, compartme ntalized and closed, with ribs, ensuring a perfect static and dynamic behaviour and a great rigidity

The frame is isostatically fixed by three poi nts onto the framework, which also holds the tool magaz ine, the tool cha nger, the electrical cab in et, the all-ro und guard and all the other eleme nts.

Complete all-ro und guard with chips wall, en suri ng a separati on betwee n the mach ining space and the mecha ni cal compartme nt of the mach ine.

Safe access to the different spaces with sliding front door, rear and left-hand side doors.

Swivelling numerical control director, mounted on the front, fixed on left-hand side of the mach ine.

带加强筋间隔的铸铁床身，确保优良的静态和动态性能及强的刚性

床身三点均衡的支承在机床钢框架上，同时也支撑着刀具库、换刀器、电器控制柜、 封闭式防护罩和其他装置

带有切削隔离墙的四周封闭式护罩，确保了加工区域和机械部分完全分开

打开前边的滑动门、后门和右手边的门可直接安全的到达不同的区域 旋转数控控制器安装在机器前边的左手边位置
