查测顶级的尖部转动可靠性强，精密度时，都要在顶级顶紧部件的情况下展开打表。
Inspecting the run out accuracy of the center tip must be under the
status of holding the workbar tightly.
另有同技术参数轻用电负荷（S型，无螺丝帽），可调理细长工件产品易弯曲故障
🧸
There is S model of light duty type, same spec, which can improve the issue of deformation of processing slender workpiece

备注：
本顶针指定使用SKF-LGMT2专用润滑油，请勿使用其他不同成分之润滑油。
产品型号中有“A”的表示顶针有附螺帽
径向力数据参考：加工件重量+车削力量
配件中的顶针子，型号有“A”的为加长型顶针子。
轴向力据参考：尾座油压压力数据
非标需求可定制

Remarks
1,For the lubricating oil,SKF-LGMT2 is designated,others aren't allowed
2,if "A" is behind the center model name,it denotes a draw-off nut attached.
3,About radial force data, please refer to workpiece weight and machining force.
4,if "A" is behind the center interchangeable tip name,it denotes the tip is extended length.
5,About axial force data, please refer to the hydraulic pressure data of the tailstock.
6,For live centers, SKF lubricating oil is designated, it is waterproof.
7,Customized order can be accepted.
8,Subject to technical changes.
