Twenty tips for using diamond dressing tools
Diamond dressing tools also known as grinding wheel dressing pen, is an essential tool for grinding wheel repair, but perhaps a lot of users do not know the use of this tool need to pay attention to the skills, today we tell you about the use of diamond repair tools need to pay attention in the use of the twenty techniques.
1 in the use of the new dresser, from the last time to repair the feed to exit. A number of brittle diamond dressing tools, at the beginning of the contact with the grinding wheel, are easy to be damaged.
2 to install the diamond dressing tool head from the angle of the inclined 10-15 angle to point the direction of rotation of the grinding wheel.
3 firmly install the dresser or clamp dressing tool, not the tool head is too long.
4 as far as possible, try to use coolant. During the whole dressing time, the cooling fluid is used in the dressing tool and the grinding wheel contact.
5 at the beginning of the repair, the highest point from the grinding wheel is repaired, usually in the middle of the grinding wheel.
6 pay attention to carry out light trace of the repair. The maximum depth of repair, except: 0.001-0.002 inch. In addition to finishing: 0.0005-0.001.
7 select the appropriate horizontal movement speed according to the relevant manual. The slower moving speed (in the allowable range), the lower the surface roughness of the grinding wheel is obtained.
8 in the specified time interval, the grinding wheel can be trimmed to prevent the grinding wheel to be blunt, and the grinding force is increased.
9 in the specified time interval, the knife clip in the dressing tool, rotating 1/8 circle, to ensure that the dressing tool is always sharp.
10 when the diamond dresser or tool head becomes dull or obviously changed, it should be adjusted and changed in time.
11 according to the diameter of the grinding wheel, the reasonable choice of CARAT (pure diamond content), the greater the diameter of the grinding wheel, the greater the choice of the CARAT value of the diamond.
9 questions need to be noted in the use of:
1 when placing the diamond dressing tool head to the clip seat, do not strike the wheel surface.
2 can not be a single point diamond dressing tool head vertically aligned with the center of the grinding wheel, the general need to tilt 10-15.
3 can not be on the heating of the dressing tool for "quenching" (refers to suddenly become cold). In dry dressing, the interval time of the two dressing must be maintained, and the cooling of the cooling tool can be sufficient.
4 can not assume that the surface of the grinding wheel has an ideal flat. At the beginning of the dressing, the highest point of the grinding wheel is found, and the dressing is carried out.
5 if possible, the amount of the grinding wheel of the grinding wheel can not exceed 0.001 inches in the radius of the wheel. Too much repair can cause the premature wear of the diamond dressing tool head and often broken.
6 but also not every time to repair a small margin. The grinding wheel used on the old or rigid machine tool can not be repaired.
7 pay attention to dressing in a position can not stay too long. This will enable the grinding wheel surface to be polished, produce high temperature and damage to the diamond dressing tool. At least one time per day, at least one of the dressing tools.
8 can not continue to use the wear or damage of the dressing tool. Should be adjusted or replaced in time.
9 cannot choose the transverse velocity and the amount of maintenance in addition too fast in the rough dressing, and then choose the transverse velocity of minor removal and slow in the finishing time. This will soon damage the diamond dressing tool. If possible, the proposed coarse trimming and finishing, choose the transverse velocity of the same.
