1、刮刀的形式、握法和刮法有很多种，主要由各地区各单位不同的传统与习惯所形成，原则上都可以使用。不过因为平板的面积大，精度要求高，所以比之刮削其他工件，要特别注意下刀的均匀性。刮研刃口应随时修磨，经常保持锋利，否则，不仅操作者体力消耗很大，而且刮出的刀痕深浅不一，很难达到每25×25mm内的点数要求。当数人在不同部位刮削同一块平板时，要有统一指挥和相互照应，务求下刀深浅与刀痕大小基本一致。
2、刮削方向最好和平板边线成45°左右，不宜平行，连续两次的刮削方向垂直交叉，不可重复。
3、刮削时要看清点子。落刀要准。不可在一处重复刮两刀。刮削应循一定方向依次刮去，切忌东一刀、西一刀。在全部刮完后，用毛刷把铁屑刷去，全面检查一遍，再统一补刮遗漏的点子。总之，既不
许重刀，又不 许遗漏，否则，每25×25mm内的斑点数是很难达到合格的。
4、每次刮削后，要用经过磨平的油石在平面上推磨一遍，倒去刮削的毛刺，防止下次拖研时划伤平面。
5、涂色剂要调和适宜，不可过干或过稀，涂层的厚薄要均匀，否则将影响显示质量。粗刮时涂色层可稍厚一些。
6、当按三面互研法刮削时，每块平板及其四角必须编上号，以免循环拖研时因为记不清而产生混乱，浪费工时。
7、平板放置应平稳牢固，高低适中，若支承点受力不均，平板工作面就会变形，而放置过高或过低，会使操作者容易疲劳。
8、必须随时注意室温的变化，一般在温度升高时平面变凹，温度降低时平面变凸，若稍不注意，就会对平面的情况作出错误的判断，以致在工作中造成混乱。
9、刮刀手柄必须有铁箍，以防阻止因手柄开裂使刮马尖尾伤害操作者。
10、拖研用的平板、平尺都很笨重，在翻转、落下和拖研的过程中，操作者要特别注意自身的安全，还要注意落下时不要让尖角磕伤平板。在拖研过程中精神要集中，切记闲谈，如果发生划伤，会发出异常的声响，则应立即停止拖左，以避免划痕扩大。

considerations
1. There are many types of scraping knives,
grips and scraping methods. They are mainly formed by different traditions and
habits of various units in various regions. In principle, they can be used. However,
because the area ofthe flat
plate is large and the precision is high, it is necessary to pay special
attention to the uniformity of the lower knife than scraping other workpieces.
The scraping edge should be ground at any time, and always keep sharp.
Otherwise, not only the operator's physical strength is very large, but also
the scratches of the knife marks are different, it is difficult to reach the
number of points within 25 × 25mm. When several people scrape the same plate in
different parts, they must have unified command and mutual care, so that the
depth of the lower knife is basically the same as the size of the knife mark.
2. The scraping direction is preferably
about 45° to the edge of the flat plate. It should not be parallel. The scraping
direction of two consecutive passes is perpendicular and cannot be repeated.
3, you must see the point when scraping.
The knife must be accurate. Do not scrape two knives in one place. Scraping
should be scraped in a certain direction, avoiding Dongyidao and Xiyidao. After
all the scraping, brush the iron scraps with a brush, check it all over, and
then make up the missing omissions. In short, neither heavy knife nor omission
can be missed. Otherwise, the number of spots per 25 × 25 mm is difficult to achieve.
4. After each scraping, use a smoothed oil
stone to grind it on the plane and pour the burrs that are scraped to prevent
the plane from being scratched when the next time.
5, the coloring agent should be blended
properly, not too dry or too thin, the thickness of the coating should be
uniform, otherwise it will affect the display quality. The color layer can be
slightly thicker when roughed.
6. When scraping according to the
three-sided mutual research method, each plate and its four corners must be
numbered, so as to avoid confusion and waste of working hours when the loop is
being dragged.
7. The flat plate should be placed firmly
and firmly, and the height should be moderate. If the support points are
unevenly stressed, the flat working surface will be deformed, and if the
placement is too high or too low, the operator will be easily fatigued.
8. Attention should be paid to the change
of room temperature at any time. Generally, the plane becomes concave when the
temperature rises, and the plane becomes convex when the temperature is
lowered. If it is not noticed, it will make a wrong judgment on the plane
condition, causing confusion in the work.
9. The scraper handle must have an iron
hoop to prevent the operator from being scratched by the sharp end of the
handle due to cracking of the handle.
10. The flatbed and flat ruler used for
mowing are very heavy. In the process of turning, dropping and dragging, the
operator should pay special attention to his own safety. Also, be careful not
to let the sharp corner hurt the flat when falling. In the process of dragging
and dropping, the spirit should be concentrated, remember to chat, if there is an
abnormal sound, if it is scratched, you should stop dragging the left
immediately to avoid the scratches from expanding.
