When processing the first-precision hole on the workpiece of the box, according to the size of the machining allowance and the dimensional accuracy and surface roughness of the hole to be machined, one or two die cutters can be used. The size of the fine boring tool can be Adjust with a fine screw. The condition of the workpiece material is old or blade casting. Cutting must be through holes to use. Cool with kerosene or diesel during processing. The application of the ring is used to machine holes with larger diameters.
When processing castings, if you choose reasonable cutting, you can achieve the first-class dimensional accuracy and the surface roughness of the foot. If you choose a blade, you can also use it to machine steel.
The remaining children of the drill bit should be properly controlled, generally in diameter, and one aid is appropriate. If the margin is too large, the margin of the hole quality is too small, and the knife can not cut the blade marks left by the drill bit, and the surface is rough. The bit sharpening must be symmetrical, and the beating tolerance of the cutting edge of the drill bit is required to be no more than one for the intestine.
In order to make the center of the flat drill and the center of the mast on the same center line, a special mandrel must be used to sharpen the flat drill to ensure that the outer diameter of the flat drill outer diameter does not exceed the coaxiality of the center of the key rod. When the tool is manufactured, a small positioning hole should be pulled out on the striker to cooperate with the flat drill connecting rod part to ensure that the coaxiality deviation between the flat drill and the building pole is not too large.
Cinnamon has a very long, interesting background; in fact, many people consider it one of the longest-existing spices in human history. The cinnamon leaf oil is yellow in color and is available in woody and spicy aroma which is extracted through steam distillation process.
The cinnamon is used in a few different ways to produce medicinally beneficial products.
