Adjustable limit snap gages are an economical choice for the go/no go measurement of outside diameters or thicknesses. They are also known as AGD snap gages. Frames are machines from stabilized cast iron and are manufactured to ANSI B47-1-1988.
ADJUSTABLE INSIDE / OUTSIDE DIAMETER FIXTURES
This comparator offers 2 or 3 point measurements for both ID and OD on one benchtop plate. Features include two or three point measurement, linear ball bushing movement and a wide range of adjustment. The fixture can be positioned at any angle from horizontal to vertical to duplicate the machining process angle eliminating deflection and deformation variation as potential sources of error. Hardened steel work surfaces insures years of accurate trouble free use.
Bore gages are comparator type instruments used to compare parts being manufactured (unknown sizes) to known dimensions. “Setting” the bore gage to a known dimension requires the use of a reference master. The master ring is the most common type reference master used in industry and each ring is limited to one specific hole size. This means that a master ring inventory can reflect a large investment. Dorsey’s adjustable bore gage setmasters maintain all the advantages of master rings, but provide the added feature of adjustability. Within the specified capacity of each Dorsey “Setmaster”, any dimension can be set by easily adjusting the master to a preset combination of gage blocks.
Dorsey's Dynamike Model DYN groove gage combines a patented ball bushing slide with a series of gaging arms to suit almost any application. Gaging contact retraction is accomplished by using a conveniently mounted thumb lever while gaging range adjustment is accomplished by sliding the static gaging arm along its precision ground rail.
