Resin wheel appear

2015-04-13 by bridge

Resin wheel appear in the production process waste is a common thing, but we as producers need to take place to minimize the probability of stainless steel cutting wheel defective products standards. Therefore, we conclude that the causes of waste resin wheel, for different reasons and then make a solution.
1, raw size discrepancies, inconsistent hardness. Measures: severely by batching single accounting ingredients is the key program review;
2, molding body cracks. Pressing temperature is too high, thermal shock commodity, off-core temperature is too low, it should promptly de-core, raw damp transformation, or mixing with a fault;
a. the end surface cracks. Molding material plasticity poor, unloading Modulo blanks wrong way. Mold floor is uneven or not parallel plate too.
b. around the cracks. Severe wear die sets, mold unloading sets, too skewed.
c. aperture crack. Blanks low intensity, unloading mode oscillation is too big, too big or taper mandrel wear too small, the order does not match the technical rules unloading mode.
d. diagonal cracks. Selected stretched spring horn, elastic deflection of pressure die without leaving a common occurrence diagonal pattern. Liaoduo fine abrasive limit too fast, time is short stick pressure, mold cooperation gap is too large.
. e crack above the precautionary approach: metal cutting discs a good mix of speed plasticity, forming tooling wear shall not exceed the standard rules, templates and horn insist outstanding flatness, thickness chosen to co-horn, horn stretch to be stretched spring common, according to technical rules of the order of release from the mold;
