VI. The rules of cutters operation
6.1 Cutters operation :
6.11 All cutters of our series are designed in clockwise way .
6.12
Must choose the collets in appropriate size . The collets that are uneven , damaged , not smooth
enough or with taper inside , can not hold cutters tightly enough .To avoid the shank shaking ,
flying off or being twisted off , must change the bad collets immediately .
6.13
The shank must be inserted in the collet with good osculation and be tightened tightly . After
tighten the shank in collet , the surface of shank is uneven or there are dents in it , which
indicates the shank slipped inside or there is deformation inside of collet. In this case ,
change the collet immediately .
6.14
Stop working with blunt cutters . Keep working with blunt cutters will increase twisting
strength of the cutter , which will cause the cutter broken or even industrial accident when
the strength exceeds the endurance of the cutter .
6.15
The working material even or curve can affect the useful life of cutters . Especially when
the cutting depth is deeper than the edge cutting depth, the part upper the edge will be touching
the working ware. In this case , the temperature of the part upper the edge will increase
heavily , which will cause the cutter deformed and broken or even facilities accident .
6.16 Put on proper eye protecting device when operating .
6.17 Keep body , clothes , hair , or other sundries away from the working material .
6.2 Choose the proper cutting speed
6.21
It is very important for cutters useful life and quality of cutting works to choose proper
cutting speed according to different working materials . Work more quickly , better , and more
safely with proper cutting speed .
6.22 Big cutters move slowly and continuously , in uniform and steady speed . Note : No pause during
cutting .
6.23
Impel the cutters with large diameter for several times to finish cutting , which will prolong
the
useful life of cutters and make operation more safely .
6.3 Cutters maintenance
6.31 Maintain the cutters clean.
Use standard cleanser that is special for cutters to clean the filth
and
impurity .
6.32 Smear an amount of machine oil on cutters surface to avoid rusting and damage.
6.33 In order to meet the demand of operation , milling process needs the particular equipments
and skills . Forbid milling cutters or changing the shapes of cutters at random, or that will
