German horse Er (Mahr) large appearance measuring instrument can use the MFK6 that metric equipment company produces at assess form each parameter of the error. Instrument by aseismatic the optimal construction part of the granite base of changeless form and high accuracy is comprised; It has axes of 7 electric machinery drive that spend freely, among them C/Z/R/X/Y is to measure an axis, a and B are to adjust an axis. circularity measures a part by measure an axis (C axis) move what sensor sets workpiece radius position to measure an axis with one each (R axis) composition. When measuring, sensor circles workpiece round have enough to meet need to move, undertake metrical below the case that can surpass sensor to measure range in prejudicial error even. perpendicular linearity measures a part (Z axis) direct installation is in move on the granite base of solid. The high accuracy slideway that goes up of the cantilever edge pillar of sensor is mobile, can measure so that the cylinder of workpiece spends, linearity, parallelism, taper, homocentric degree, coaxial is spent, the error such as jumpy, verticality. perpendicular direction (Z axis) measure limits to amount to 1000mm, because this is measurable,grow an axis. Install sensor the purificatory light and strong lengthen staff in different length to go up to be able to be opposite long axis the form of each place the error undertakes metrical. Change the lengthen lever of other length, the form of the other place that can measure this axis error. The applied range of MFK6 is extremely wide, the accurate main shaft that is used at checking equipment of casting die of lid of motor component, casing, air cylinder, crankshaft, camshaft, piston, connecting rod, fluid, machine tool and other machinery for example, axle sleeve, bearing.
