LSK5705上拉式硬拉床是我公司自主研發具有知識產權的新產品，對主要部件通過三維建模、三維分析采用*的工藝手段制造出的國內*臺高速數控上拉式硬拉床。此型號拉床加工效率*，工件單件加工成本大幅降低，可帶自動上下料機械手連線生產。

LSK5705主要針對熱后工件的內孔、內花鍵及各種不同形狀內齒進行整形加工；工件被拉削部位的zui高硬度可達HRC60以上，是提高工件的內孔、內花鍵、內齒輪等表面粗糙度和齒形精度的關鍵設備。硬質合金刀具刃磨一次可拉削工件近萬個，共可刃磨15次左右—。

LSK5705 high-speed CNC upward hard broaching machine is special product independent research and development by our company. the main components are 3D modeling and 3D analysis, the first high-speed CNC upward hard broaching machine in China manufactured by advanced technology and method. This broaching machine is high processing efficiency. the processing cost of workpiece is economy, The machine can apolegamy Automatic material delivery machine then。

This broaching machine used for broaching quenched inner bore. internal spline and various kinds internal tooth . the highest hardness reach HRC60, it's key equipment to enhance precision. The hard alloy broach can broaching ten thousand work piece per sharpening and can sharpening frequency 15 times.
