Impact specimen notch broaching machine Common faults and Solutions
In the impact test, the impact specimen notch broaching machine is an indispensable sample preparation equipment, which is specially used for processing V-shaped and U-shaped notches of impact samples. In the process of using the equipment, some problems will inevitably be encountered. For non professionals, a small problem may not know how to deal with it, thus affecting the test progress, HuiFu small editor to summarize the impact sample notch broaching machine common faults and failure causes and solutions:

1 Broach stop in broaching
Reason 1: Insufficient power of broaching machine Use high power broaching machine.
reason two Chip deposition Blade breakage Abnormal wear increases the cutting force Regrinding to remove the deposits and damaged parts, and replace the lubricating fluid.
reason three The change of workpiece material makes chip performance worse Check the composition and hardness of the workpiece, and make the lubricant more smooth.  
reason four : chip blockage Check whether the workpiece longer than the specified length is processed and remove the chips.  
2: Chattering in broaching
reason one Insufficient rigidity of machine tool and fixture Increase the rigidity of machine tool and fixture.
reason two After elastic machining, the workpiece is restored Increase the wall thickness of the workpiece.
reason three : the relationship between blade pitch and chip length is out of balance Broach with rear support.  
reason four : too few cutting edges are involved in the chip at the same time Check if the workpiece is shorter than the specified length. If it is shorter, repeat broaching is required.  
3: Workpiece broaching notch defect
reason one : blade defect Regrinding to remove damage.  
reason two : blade bruise The injured part was removed by regrinding.  
reason three There is deposit on the blade Regrinding to remove the deposit and change the cutting fluid.
4: Broaching surface is not smooth
reason one : blade wear, scratch machining surface Regrinding improves sharpness.
reason two There is deposit on the blade Regrinding to remove deposits, more slippery cutting fluid.  
reason three : blade defect Regrinding to remove damage.
reason four : the chip scrapes the surface of the workpiece Remove the chips and change the lubricant.
5: Large burr on broaching surface
reason one : the change of workpiece material results in the decrease of cutting performance Check the material and hardness of the workpiece.  
reason two : reduced cutting sharpness Regrinding improves sharpness.
