根據中國(guo)機(ji)(ji)床工具工業(ye)協會(hui)重點聯系企業(ye)的(de)統計(ji)數據，,自動化機(ji)(ji)床銷售2014年1~6月全部企業(ye)的(de)產品總體銷售收(shou)入同比下(xia)降(jiang)2.6%。其中，金(jin)屬切削(xue)機(ji)(ji)床產品銷售收(shou) 入同比下(xia)降(jiang)7.7%；金(jin)屬成形機(ji)(ji)床產品銷售收(shou)入同比增(zeng)長4.3%。持定力，主動作為。這是(shi)機(ji)(ji)械行業(ye)絕大多數企業(ye)對當下(xia)市場(chang)形勢的(de)判斷以及抉擇。
