Blade Position Adjustment Of BT-300 Chamfering Machine

The description of BT-300 chamfering machine

This device is manually operated for blade chamfering grinding. It is made up of the grinder and assembly fixtures. This machine is composed of a spindle motor, feeding mechanism and insert positioning device. According to the negative chamfering angle of inserts, the insert is put on the positioning device. The feeding mechanism controller grinding amount. And the negative chamfering of the insert is manually processed on the end surface of the grinding wheel. It is grinding for the insert's straight edge and arc blade. The supporting angle positioning iron has 15°, 20°, 25°, 30°, and 35°.

Blade position adjustment

BT-300 chamfering machine can not only adjust the angle of the chamfering but also control the width of the chamfering. The vertical distance between the insert fixed plate and the grinding wheel determines the width of the chamfering edge. The closer the distance is, the greater the width of the chamfering edge is. BT-300 uses two handwheels in the feed mechanism to adjust the vertical distance between the blade fixed plate and the grinding wheel. The lower handwheel moves 0.01mm in the horizontal direction of one lattice and moves one cycle per rotation of 1.5mm. The upper handwheel moves 0.0097mm in the horizontal direction of one grid. Moves 0.0026mm on the vertical direction moves 1.45mm on the horizontal direction of one circle. And moves 0.39mm in the vertical direction. When the insert is chamfering, two handwheels are used to adjust the insert fixed plate to keep the insert and the grinding wheel in the right position. With the abrasion of the grinding wheel, the position of the fixed plate of the blade must adjust at the same time, and the adjustment method is the same.
