  • 镗刀的安装步骤
  • 本站编辑:穆格精密工具(杭州)有限公司发布日期:2019-07-13 07:29 浏览次数:

镗刀是孔加工刀具的一种,一般是圆柄的,也有较大工件使用方刀杆一般见于立车,最常用的场合就是里孔加工,扩孔,仿形等。但是并不是只能加工里孔,端面外圆也是可以加工的,只是习惯上不是这样使用

镗刀的安装步骤

1、将刀桥用螺栓1连接在刀柄上

2、将精镗刀座安装在刀桥上

3、将配重块安装在滑动体上

4、刀具调整:

1)松开锁紧螺钉;

2)根据刻度线粗调刀座,刀尖尺寸小于要加工尺寸0.5mm左右,[ 注意:通过复合调整精镗刀座与刻度盘来保证粗调尺寸];

3)拧紧锁紧螺钉,拧动调整螺钉(精镗刀座上的),顶紧锁紧螺钉杆部,以防让刀;

5、用同样方法调整配重块,调好动平衡;

6、锁紧锁紧螺钉,试镗,测量加工孔的尺寸与要求尺寸比较,计算出偏小数值;

7、松开锁紧螺钉,旋刻度盘(刻度盘每转动一小格代表0.01mm的直径切深变化),使移动量至计算出的偏小数值;

8、锁紧螺钉,加工工件至尺寸.

注意事项:

注意精镗刀头的调整,请勿过分用力(切莫旋转刻度盘超出范围);

用红漆封堵的地方不能拆动,否则会损坏微调装置;

定期保养,注润滑油.

Boring tool is a kind of hole processing tool, generally round handles, and a larger workpiece using a square knife rod is generally seen in the car. The most commonly used occasions are hole processing, hole expansion, and profiling. However, it is not only possible to process the inner hole, but also the outer circle of the end surface can be processed, but it is not customarily used in this way.
Installation steps for boring cutter
1, bolt the bridge with a bolt 1 on the handle
2, install the fine boring knife base on the knife bridge
3, the weight block is installed on the sliding body
4, tool adjustment:
1) Loosen locking screws;
2) According to the rough adjustment of the scale, the size of the knife tip is less than 0.5 mm of the desired size,[ Note: The rough size is guaranteed by compound adjustment of fine boring knife base and dial.] ;
3) Tighten the locking screws, unscrew the adjusting screws(on the precision boring knife holder), and tighten the locking screw bars at the top to prevent the knife from being used;
5, use the same method to adjust the weight block, adjust the balance;
6, lock the lock screw, test boring, measuring the size of the machining hole and the required size comparison, calculate the partial small value;
7, loosen the lock screw, twist the disk(the dial of the dial represents a change in diameter and depth of 0.01 mm per rotation), so that the amount of movement to the calculated small value;
Lock screws and process the workpiece to size.
Notes:
Pay attention to the adjustment of the boring knife head, do not excessively force(do not rotate the dial beyond the scope);
The place sealed with red paint can not be removed, otherwise it will damage the fine-tuning device;
Regular maintenance, lubricating oil.
