U钻在数控机床上的使用注意事项
Attention to the use of U drilling in CNC machine tools
1、使用U钻时一定要考虑机床主轴功率、U钻装夹稳定性、切削液的压力和流量,同时控制好U钻的排屑效果,否则将在很大
1, when using U drilling, we must consider the power of the spindle of the machine tool, the stability of U drill clamp, the pressure and flow of the cutting fluid, and control the effect of the cuttings of the U drill, otherwise it will be very big.
度上影响孔的表面粗糙度和尺寸精度。
Degree affects surface roughness and dimensional accuracy of holes.
2、使用U钻时,中心刀片应选用韧性好的刀片,周边的刀片应选用比较锋利的刀片。
2. When drilling with U, the blade should be chosen with good toughness. The blade should be sharpened.
3、U钻使用时对机床的刚性、刀具与工件的对中性要求较高,因此U钻适合在大功率、高刚性、高转速的数控机床上使用。
3. When the U drill is used, the rigidity of the machine tool and the neutral requirement for the tool and the workpiece are higher, so the U drill is suitable for the CNC machine tools with high power, high rigidity and high speed.
4、使用U钻钻孔时,可采用工件旋转、刀具旋转以及刀具和工件同时旋转的方式,但是当刀具以线性进给方式移动时,最常用的方法是采用工件旋转方式。
4. When drilling with U, workpiece rotation, tool rotation and tool and workpiece rotation can be rotated at the same time. But when the tool moves in linear feed, the most commonly used method is to rotate the workpiece.
5、 加工不同材料时,应选用不同槽形的刀片,一般情况下,小进给、公差小、U钻长径比大时,选用切削力较小的槽形刀片,反之粗加工、公差大、U钻长径比小时则选切削力较大的槽形刀片。
5. When different materials are processed, the blade with different grooves should be selected. In general, when small feed, small tolerance, and long diameter ratio of U drill are large, the groove shaped blade with smaller cutting force is selected, and vice versa of rough machining, large tolerance and U drilling length ratio is selected.
6、使用U钻时,要根据不同的零件材料,选择合适的切削参数。
6. When drilling with U, proper cutting parameters should be selected according to different parts.
7、使用U钻加工阶梯孔时,一定要先从大孔开始加工,再加工小孔。
7, when using U drill to process stepped holes, it is necessary to start machining from big holes and then process small holes.
8、使用U钻加工时,刀片出现磨损或破损时,要仔细分析原因,更换韧性更好或更耐磨刀片。
8. When drilling or machining with U, wear and tear should be carefully analyzed, and better or more wearable blades should be replaced.
9、装夹U钻时,一定要使U钻中心与工件中心重合,并垂直于工件表面。
9, when clamping U drill, make sure that the U drill center coincides with the center of the workpiece and is perpendicular to the surface of the workpiece.
10、U钻使用时注意切削液要有足够的压力,以便将切屑冲出。
10. When drilling U, pay attention to the sufficient pressure of the cutting fluid to rush out the chips.
11、U钻上中心和边缘所使用的刀片是不同的,千万不可错用,否则将会损坏U钻刀杆。
11, U drill center and edge of the blade used is different, must not be misused, otherwise it will damage the U drill rod.
12、U钻试切削时,一定不要因小心害怕而随意减小进给量或降低转速,而使U钻刀片破损或U钻损坏。
12, U drilling test cutting, we must not be careful and fear to reduce the feed rate or reduce the rotational speed, so that the U drill blade damaged or U drill damage.
