Special-polishing process for tools with hyper smooth surfaces 1
Special-polishing process MMP Technology By selective machining of the micro-roughness cutting edges and surfaces of HAM tools can be manufactured in reproducible superior precision. Significantly better surface finish than conventional polished tools! 2
The MMP Surface Study – Basics 3
The MMP Technology Treatment Eliminate 4 th order defect Application of particles which are aggregated to simulate High Frequency Range 4
The MMP Technology Treatment Eliminate 3 rd order defect Application of particles which are aggregated to simulate Medium Frequency Range 5
The MMP Technology Treatment Eliminate 2 nd order defect Application of particles which are aggregated to simulate Low Frequency Range 6
The MMP Technology Treatment Eliminate 2 nd order defect Result = Form 7
The MMP Technology Treatment Before MMP HAM tools are treated with a defined and fix batch process. The surface specific characteristics are significantly improved. After MMP Basically it is possible to set the roughness as per request. 8
The MMP Technology Applications 9
The MMP Technology Removal of micro-burrs and stabilisation of the cutting edge with MMP Technology Before MMP After MMP 10
The MMP Technology The MMP technology treatment is suitable for: o Solid carbide tools o Solid carbide tools with CVD or PVD coating o PCS-equipped tools with the basic body made of carbide o Standard and special tools from nominal-ø 0,5 mm and shank-ø 3,0 mm Major and minor cutting edges, flutes and guide chamfers are processed in this way. 11
The MMP Technology - Advantages Advantages: o Optimal chip removal o Reduction of built up edges o Defined cutting edge rounding o Homogeneous and reproducible surfaces can be reached 12
The MMP Technology - Advantages Additional advantages: o Higher cutting speeds and feed rates are possible o Reduced cutting forces o Less heat generation on the tool and workpiece 13
The MMP Technology – Re-sharpening HAM re-sharpening: - Original point grinding - Original geometry - Original coating - With/without MMP Technology 14
