Project Description

Heel Top Piece Sample Grinding Machine

AT-F3048 Heel End Sample Grinder China Supplier

This machine is used for sample grinding of the leather shoe’s top piece when determining the abrasion resistance of the top piece using the rotating cylindrical drum method.

It is mainly used to grind the sample when the test piece is not suitable for cutting with a rotary cutter or grinding the non-standard leather heel test piece into a sample with a diameter of 16 mm required.

It is a perfect sample preparation equipment when we use DIN Abrasion Tester to do heel wear tests.

Test Principle

The motor drives a grinding wheel with a 100 ~ 120 mm diameter at the speed of 2800 r / min. The grinding wheel is white corundum with a graininess of 60. The linear velocity of the grinding wheel is 15 m / s ~ 20 m / s. The sample is fixed in the clamping device, rotated at a speed of 50 r / min ~ 60 r / min when grinding the cylindrical surface. The distance between the grinding wheel and the clamping device is adjustable. When the sample rotates approaching the grinding wheel, the sample will be ground by the wheel until the cylindrical specimen with a diameter of 16 mm is achieved.
