What Are The Characteristics Of Milling Cutter?

The lining face of the friction disk should be free from the defects such as mechanical scratches, damages or peeling-offs etc.
The exposed local portion of the lining face of the friction disk should be 0.04cm2 max in area and but not more than 4 places.
The material for the lining face of the friction disk should be the compound material JS. After copper powder sinter into two layers. The tooth flank of the backing steel should be free from copper powder. The tooth flank outside the tooth root circle may have the sintering layer without copper powder.
Check the exchange ability using the matching part (.122.14.11)
The leveller for friction disk should be used for less than 3 times. The direction difference for twice levelling should be 90 checks the flatness after leveling.
Acceptance for the friction disk should be carried out according to acceptance and technical requirements for friction disk of compound material (tentative) Q Lb198-87 JST. The strength of bearing pressure may be tested in the method of sample of single face and test dimensions should be ensured by process.
Among which
(Z101) a            1.1.1    Friction Coefficient
(Z102) b            1.1.2   Adhesive Strength of compound material
(Z103) c            1.1.4   wearing performance
(Z104) d            1.1.5   Bearing pressure strength


It is allowed to clamp 20 pieces of outer toothed friction disks under the pressure 5000 N. Measure the assemble dimension on the condition that the closely contact with each other.
