What industries are Er extension rods generally used in

ER extension rod, also known as extension rod, straight handle, tool extension rod, lathe end milling cutter rod and NC turning and milling fixture, is mainly used to process workpieces with limited space, insufficient tool handle space and extended spindle stroke. The utility model has the advantages of high body precision, good matching precision and low price, and there are a variety of suitable collets (also known as snap springs, collets, lengthy, etc.). Therefore, it is deeply loved by machining centers and hardware processing.

1. The main types of extension rods are: 1. NC extension rod, 2. Pull back extension rod, 3. Double headed extension rod, 4. Extension rod of inner top screw, 5. Extension rod fixed on the side, 6. EC extension rod, 7. Tapping extension rod.

2. Function of telescopic rod: all telescopic rods are mainly used for expansion and conversion. Different extension rods have different application environments.

Rear pull extension rod: it is mainly used for lathes (generally Japanese xiteicheng / Tianjin superior, and there are many domestic brands) to cut the plane fixed on the machine tool with the side of the extension rod. There is a through hole in it, but there is a pull back thread. The pull back thread is used to fill the water or oil joint.

ER extension rod is widely used in mechanical field, such as machining center, lathe, drill bit, tapping machine, milling machine, etc. The definition of cutter bar can be roughly summarized as a steering bar connecting the machine tool spindle with the tool (or workpiece) and other auxiliary tools (such as vertebral body). Er extension rod is an elastic clamping device, which clamps the tool and workpiece by connecting the spindle. The ER extension is commonly referred to as the machine extension. The names vary according to the toolbars on different devices.
