Enclosed grating feet: Can effective dustproof, prevent cut bits and prevent splattering cutting fluid, it is the ideal option that is used at the machine tool. Open wide type grating feet: Mix with reading head contact without machinery between grating feet or metal strip. The representative application of these grating feet includes: Measure machine, comparator and other length gauge to measure nicety equipment and production and measure equipment, use in semiconductor industry for example. Feet of increment type grating: The way that decides current position is the computation signal amount that begins number to measure step pitch or fractionize circuit by origin. Feet of increment type grating contains reference point, reference point must be carried out to wind 0 operations when switching on the mobile phone very simple, quick. Feet of very form grating: Need not carry out reference point to answer 0 operations to be able to offer current position value directly. The absolutely position value of grating feet passes EnDat interface or serial interface transmits other. Length gauge: Hai Dehan's length gauge takes measuring staff slideway oneself. Can use at industry is measured metricly to equipment is monitored and use as positional coder. CNC MillingCNC Machining
