Back Turning Inserts
MZG Tool Machine provides comprehensive and professional Back Turning Inserts, focusing on TBP and TKFB series. These highly specialized inserts are indispensable for modern precision machining, particularly in automated environments like Swiss-type lathes and CNC turning centers for secondary or reverse turning operations.
Specialized Back Turning Design
Engineered specifically for back turning operations on Swiss-type lathes and CNC turning centers, providing exceptional stability and precision in secondary machining operations.
Robust Peach Shape Geometry
TBP series features strong 80° negative angle geometry with peach-shaped design, delivering exceptional edge strength and resistance to chipping in demanding applications.
Precision TKFB Technology
TKFB series provides high-precision finishing with positive rake geometry and integrated chip breakers, ensuring superior surface quality and dimensional accuracy.
Product Performance
Back turning, also known as secondary or reverse turning, is an external machining operation performed on the spindle side of a workpiece. This technique is critical when conventional turning from the tailstock end is impractical or impossible.
Common scenarios include machining features close to the collet, finishing a part before cutoff to eliminate a residual pip, or when the component's geometry obstructs a standard tool path. Back turning inserts are engineered to excel in these unique conditions.
Our TBP and TKFB series provide exceptional stability, precision, and superior surface finishes in automated environments like Swiss-type lathes and multi-spindle turning centers.
