Millimar Pneumatic Length Metrology M 7-63 Mahr Dimensionair Air Rings Options for Air Rings Carbide wear strips Air plugs are normally furnished chromed for long life. Other materials can be provided to improve the life of the ring when high volume or grinding grit may still remain on the part. Materials such as Ferrotic and addition of carbide strips can be provided. Bases for air rings Depending on the application there are many ways to hold an air ring. They may be hand held and placed over the part if the part is still on the machine. They may be front mounted horizontally or vertically on the Dimensionair or for larger parts the can be mounted to a base and held vertically or horizontally. Special bases are available the mount the ring horizontally and incorporate a part lifting mechanism to aid in part removal. Guide chutes Guide chutes and vees are available in a host of options to improve the inspection process. Vee type guide chutes can be furnished on one or both sides of an air ring from 6.3 mm .248 through 44.5 mm 1.75. Other options include tube type guide chutes for sizes 6.3 mm .248 through 63.5 mm 2.5. Standard length of the guide chutes are 63.5 mm 2.5 and affix to the side of the air ring. Normal length of the chute is 63.5 mm 2.5. Other options including heavy duty out riggers and universal vee stands can be provided. Options for Air Snaps Since side clearances can present gaging problems with crankshaft diameters or similar applications Mahr Federal designed a new line of air snaps that make the tough measurements easier and affordable. We based our new air snap design on our own proven air tooling techniques known for providing long life and high-resolution in tough shop environments. Now you can measure fixed sizes from 12.5 mm .49 through 184 mm 7.25 using D-2500 and D-5000 systems. Widths are typically 19 mm .75 but can be customized to reach diameters having tight clearances. Jet locations can be located central in the snap or positioned close to either side for exploring close to a shoulder. Multiple circuit air snaps are available for speeding the process while checking the journal for size variation taper barrel or hourglass shape. +
