小直径的深孔加工是机械加工中较困难的工序,而长径比l/d>20深孔的多轴同时加工更为困难。我厂生产的橡塑机械中,有大量如图1所示的A3钢平板,须在其内钻出均匀分布的φ27mm深孔13个。由于该零件加工较困难,一直使整机产量不能提高。为此,我们设计并制成了一台ZS-14专用深孔钻床,能一次加工14个深孔(其中一个头备用)。经过一年多来的使用实践,该机床的性能基本稳定,加工精度能够达到图纸要求。
Small-diameter deep-hole machining is a more difficult machining process, and long-diameter ratio l / d> 20 deep-hole multi-axis simultaneous machining more difficult. I plant rubber and plastics machinery, there are a large number of A3 steel plate shown in Figure 1, to be drilled inside the hole evenly distributed φ27mm 13. As the parts processing more difficult, has been to make the whole output can not be increased. To this end, we have designed and manufactured a ZS-14 dedicated deep hole drilling machine that can process up to 14 deep holes at a time (one for head use). After more than a year of practice, the machine’s performance is basically stable, the processing accuracy can reach the drawing requirements.
