VL-50-B/50S-B Litematic SERIES 318 — High-accuracy/resolution Measuring Machine
Optional Stand for VL-50S-B
• With a measuring force of only 0.01 N, the Litematic is ideal for measuring easily deformed workpieces or high-accuracy components. • For workpieces for which 0.01 N is insufficient, either the 0.15 N or 1 N model is recommended. • The motor-driven spindle moves up/down and stops when the contact point touches the workpiece. Then the maximum, minimum and runout values are measured under a constant force.
• High resolution of 0.01 µm, and wide measuring range of 50 mm.

• Measuring system VL-50-B , integrated display type, and VL-50S-B , a separate display type, are available. • The measuring table supplied with VL-50-B is ceramic, which is corrosion free, for easier maintenance and storage. • The spindle is made of low thermal expansion material.

Standard Accessories
*1 Normal measurement using standard contact point. *2 Under less temperature change, and hot or cold direct air flow should be avoided. *3 0.15 N, 1 N types are factory-installed option. Note: Motor life is approximately 100,000 operations, after which replacement is advisable. This maintenance factor is particularly important to bear in mind when the machine is used frequently, such as on a production line.
