Mahr Federal'sMarCheck measuring and evaluation unit is for its high precision Linear100 universal length measuring instrument. MarCheck allows both measurementsand calibrations to be performed quickly and reliably at the touch of a button.Results are shown in large digits on the display screen and can be output viaUSB or RS 232 ports. With a direct measuring range of up to 50 mm (2 in.) andan application range of up to 100 mm (4 in.), the Mahr Federal Linear 100provides internal and external measurements directly on the shop floor.
Easy-to-usemenus guide operators, and measurements are performed systematically usingfunction keys. The Linear 100 withMarCheck offers analternative to rings and gage blocks for shop-floor mastering of inner andouter comparative measuring equipment, 2-point measuring instruments, insidecalipers and dial comparator snap gages. MarCheck upgrade packages are alsoavailable for older length measuring machines.
The Linear 100 has an adjustable 76x 76 mm (3 x 3 in.) measuring table for precise adjustment of part position whenmeasuring ODs and a 4 to 40 oz (1to 11 N) adjustable measuring force that remains virtually constant over theentire measuring range. For ID measurement, the 100 mm (4 in.) x 185 mm (7.3in.) worktable allows for precision part positioning for measurement. Theintegrated measuring system is based on the Abbe principle (i.e., the measuringarm and reference are in line) which eliminates cosine errors.
Internal/External measurements, as well as Combined Internal/External measurements, are possible without remasteringand easily interchangeable measuring anvils provideincreased part measuring versatility. The solid cast body reduces stresses and twisting error and a large digital display provides clear readouts withselectable ID/OD results and preset values. An RS-232 interface makes it easyto transfer output data to PCs, and optional software allows measured values tobe transferred to Windows programs such as Microsoft Excel.
Most machine design engineers will survey existing component manufacturers for standard linear guide products, limiting what they can do with their designs. Using extruded aluminum profile guides can customize machine designs while shrinking the bill of materials.
Practically all electronic devices today contain metals that may
be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
