Experience has shown, that the most optimal belt-grinding is only achieveable on a high quality, specifically chosen contact wheel.<\/p>\n

The wrong choice or incorrect use of the contact wheel leads to poor belt performance and subsequent low quality grinding results.<\/strong><\/p>\n

Hardness<\/h4>\n

The hardness of rubber or polyurethane contact wheels is measured in
\ndegrees shore A.
\n30\u00b0 Shore A = very soft
\n40\u00b0 Shore A = soft
\n60\u00b0 Shore A = medium
\n80\u00b0 Shore A = hard
\n90\u00b0 Shore A = very hard
\nPlastiflex- and Permaflex contact wheels.
\nHardness quality: \u201cmedium\u201d, \u201csoft\u201d and \u201cextra soft\u201d.<\/p>\n

Rubber, PU, Plastiflex and Permaflex coatings<\/h4>\n

These materials are ideal for dry, wet or oil grinding with various grit sizes and belt types, X or J belts.<\/p>\n

Polyurethane Coatings<\/h4>\n

This material is resistant to mechanical wear,oils and fats.
\n50\u00b0 \u2013 95\u00b0 Shore A
\nTypes A8, A11<\/p>\n

Rubber Coatings<\/h4>\n

This material is oil and acid resistant
\n30\u00b0 \u2013 90\u00b0 Shore A
\nTypes A66, A77, A970<\/p>\n

Foam Coatings<\/h4>\n

Mild grinding, oil and water resistance.
\nThese soft Plastiflex and Permaflex contact wheels show minimum wear on extended use. Excess pressure leads to heating of the coating with consequent melting, this should be avoided at all costs.
\nTypes A9, A90, A10, A100, A14, A15, A16<\/p>\n

Textile Coatings<\/h4>\n

Textile coatings are ideal for dry use and particulary fine processing. The advantage of textile coatings is minimum vibration and hardly any noise in running (very low decibel).
\nType A1<\/p>\n

Recycling<\/h4>\n

Rubber rollers and contact wheels with aluminium cores can be economically recovered with a new coating. Contact-wheels with plastic centers cannot be re-used and re-covered. For this reason we prefer to manufacture contact wheels with aluminium cores, where re-cycling is possible.<\/p>\n

Grooving<\/h4>\n

The deeper and wider the grooving the more aggressive the effect of the abrasive grit and the higher the stock removal. Flat coated contact wheels are more ideal for finer grit sizes.<\/p>\n

grooving No. 2: fine, uniform grooving for fine grinding
\ngrooving No. 3: standard grooving for universal grinding (most commonly used grooving)
\ngrooving No. 6: \u201csaw-tooth\u201d grooving for coarse grinding<\/p>\n

\"Rillungen\"<\/p>\n

Hardness<\/h4>\n

The harder the contact wheel the greater the stock removal. The contact wheel should be as hard as work part contours allow. Highly contoured work parts require softer contact wheels.<\/p>\n

Coated Abrasive Belts<\/h4>\n

Harder contact wheels, 60\u00b0\u201390\u00b0, are used with less flexible X-backed cloth abrasive belts. Softer contact wheels are used with flexed or softer J-backed cloth abrasive belts.<\/p>\n
