1Overview of high-precision internal grinding machine for engine guard seat:
A certain automobile engine parts company in Sichuan needs to purchase an internal grinding machine that can grind the inner circle of the engine guard seat. We conducted research on multiple domestic and imported machine tool companies, but later chose Shenyang Haimer CNC internal grinding machine because this high-precision internal grinding machine for the engine guard seat not only meets the machining requirements of the workpiece, but more importantly, for this type of wall thickness, only1mmOur grinder has a great advantage in producing thin-walled parts,CPK(Stability)>1.33The scrap rate is extremely low.
