CSA Herzogenburg 公司专门从事复杂铸件制造业务,并且拥有将工件精加工至最终安装状态的关键技术。为此,公司主要依靠海科特定制的两台 HEC 630 Athletic 卧式加工中心完成机械精加工工艺。主要业务涉及因铸件几何形状或尺寸较大而导致生产工艺复杂的商用车底盘部件和大型部件。

公司因海科特 HEC 630 Athletic 机床工作区域较大而且稳定性较高而购买机床。机床夹紧区域 800 毫米 x 630 毫米,可实现干涉回转直径 1,250 毫米(水平情况下,最高 1,550 毫米),最大工件高度 1,250 毫米。机床床身可进行单独调节,即便加工大型部件也可以确保高水平的流程可靠性。通过调节,NC 转台可承载重量不超过 1,500 千克的工件。可将转速从 70 转每分提升至最高 500 转每分,这意味着也可以用于车削操作。从而大大提高生产能力。主轴最高速度 15,000 转每分,可通过无齿轮系统 HSK-A 100 接口将 82 千瓦的驱动力传输至刀具。刀库提供 80 个刀位,最大刀具长度 800 毫米。刀库所承载刀具重量最高 35 千克。

Athletic 机床在加工大型或重型工件时可发挥最大潜能。加工中心 X/Y/Z 轴最大运动速度 65 米/分钟。加速度可根据相关工件进行调节,确保加工时间最优化。HEC 630 设计坚固,可在 X 和 Y 轴确保约 7 米/秒² 的加速和制动。“对我们而言,2 台 HEC 630 Athletic 机床正是非常完美的设备。机床根据机床零件的要求精确调校,可在确保始终如一的高加工质量下提供最大生产能力。这为我们提供了与流程同样出色的加工可靠性,与我们对客户的承诺完美契合”,CSA 常务董事 Markus Kieberger 说道。

higher productivity

So, in February 2014, the first Heckert HEC 630 Athletic has been purchased. The essential decision criteria in favor for the horizontal machining center were the large working area and the high stability. At a clamping surface of 800 x 630 mm, the HEC 630 Athletic allows an interference diameter of 1,250 mm (flattened up to 1,550 mm) and a maximum work piece height of also 1,250 mm. “Heckert could prevail not least also because of the possibility to adapt the machine exactly to our demands. For example, also modifications at the machine stand have been made, for a better machining of large parts with high process reliability”, says a pleased Mister Kieberger. Thereby, the NC rotary table can carry a work piece weight of up to 1,500 kg. The rotational speed of 70 rpm can be optionally increased to up to 500 rpm and thus, it can even be used for rotating operations. The traverse paths of (X/Y/Z) 1,200 x 950 x 1,200 mm offer sufficient space for the machining of large parts. The spindle with its rotational speed of up to 15,000 rpm transmits the drive power of 82 kW without gearbox via a HSK-A 100 interface to the tool. The tool magazine offers 80 storage spaces with a maximum tool length of 800 mm. The tools may have a weight of up to 35 kg. In January 2015, another HEC 630 Athletic has been purchased. This one is, except an adapted spindle, identical in construction to the first machine. “Our main aim has been a capacity expansion”, Kieberger explains. “With the first machine, we perform 19 weekly shifts with almost always the same parts. On one hand, the new sister machine allows us to increase the throughput for this part, on the other hand it also allows to additionally produce other parts in alternating operation”, he adds. The machines are arranged in a machining cell shifted by 90° to one another and can be loaded and unloaded from the same work place with crane support.

Especially in machining of large and heavy work pieces, the Athletic fully brings its performance ability to bear. The axes X/Y/Z of the machining center move with a speed of up to 65 m/min. In doing so, the acceleration rates can be adapted to the respective work piece and so, the machining times can be optimized. The robust construction of the HEC 630 allows acceleration and brake value in the range of 7 m/s² in X- and Y-axis. “For us, the two HEC 630 Athletic are the perfect “workhorses”. Exactly adapted to the requirements of the parts to be machined, they offer a maximum level of productivity at a constantly high machining quality. Hence, it offers exactly the process reliability that we guarantee to our clients”, Kieberger summarizes pleased.
