Quick Guide to Precision Measuring Instruments Micrometer Heads Key Factors in Selection Key factors in selecting a micrometer head are the measuring range, spindle face material and shape, accuracy, stem type, graduation style and thimble diameter. Stem Constant-Force Device Plain stem Stem locknut type B The stem used to mount a micrometer head is classified as a plain or locknut type as illustrated above. The stem diameter is manufactured to a nominal Metric or Imperial size with an h6 tolerance. The clamp nut stem allows fast and secure clamping of the micrometer head. The plain stem has the advantage of wider application and slight positional adjustment in the axial direction on final installation, although it does requires a split-fixture clamping arrangement or adhesive fixing. General-purpose mounting fixtures are available as optional accessories. Measuring Face Flat face Spherical face Micrometer head with constant-force device Micrometer head without constantforce device (no ratchet) Spindle Lock If a micrometer head is used as a stop it is desirable to use a head fitted with a spindle lock so that the setting will not change even under repeated shock loading. Anti-rotation device A flat measuring face is often specified where a micrometer head is used in measurement applications. When a micrometer head is used as a feed device, a spherical face can minimize errors due to misalignment (Figure A). Alternatively, a flat face on the spindle can bear against a sphere, such as a carbide ball (Figure B). A non-rotating spindle type micrometer head or one fitted with an antirotation device on the spindle (Figure C) can be used if a twisting action on the workpiece must be avoided. If a micrometer head is used as a stop then a flat face both on the spindle and the object it contacts provides durability. Figure A A micrometer head fitted with a constant-force device (ratchet or friction thimble) is recommended for measurement applications. If using a micrometer head as a stop, or where saving space is a priority, a head without a ratchet is probably the best choice. Figure C Measuring Range (Stroke) When choosing a measuring range for a micrometer head, allow an adequate margin in consideration of the expected measurement stroke. Six stroke ranges, 5 to 50 mm, are available for standard micrometer heads. Even if an expected stroke is small, such as 2 mm to 3 mm, it will be cost effective to choose a 25 mm-stroke model as long as there is enough space for installation. If a long stroke of over 50 mm is required, the concurrent use of a gauge block can extend the effective measuring range. (Figure D) Figure D Figure B Gauge block Head’s stroke Obtained stroke Non-Rotating Spindle A non-rotating spindle type head does not exert a twisting action on a workpiece, which may be an important factor in some applications. In this guide, the range (or stroke end) of the thimble is indicated by a dashed line. For stroke ends, consider the thimble as moving to the position indicated by the line when designing the jig. Spindle Thread Pitch Ultra-Fine Feed Applications The standard type head has 0.5 mm pitch. 1 mm-pitch type: quicker to set than standard type and avoids the possibility of a 0.5 mm reading error. Excellent load-bearing characteristics due to larger screw thread. 0.25 mm or 0.1 mm-pitch type This type is the best for fine-feed or fine-positioning applications. Dedicated micrometer heads are available for manipulator applications, etc., which require ultra-fine feed or adjustment of spindle. B-99

Thimble Diameter Graduation Styles The diameter of a thimble greatly affects its usability and the fineness of positioning. A small-diameter thimble allows quick positioning whereas a large-diameter thimble allows fine positioning and easy reading of the graduations. Some models combine the advantages of both features by mounting a coarse-feed thimble (speeder) on the large-diameter thimble. Care is needed when taking a reading from a mechanical micrometer head, especially if the user is unfamiliar with the model. The normal graduation style, identical to that of an outside micrometer, is the standard. For this style the reading increases as the spindle retracts into the body. On the contrary, in the reverse graduation style the reading increases as the spindle advances out of the body. The bidirectional graduation style is intended to facilitate measurement in either direction by using black numerals for normal, and red numerals for reverse, operation. Micrometer heads with a mechanical or electronic digital display, which allow direct reading of a measurement value, are also available. These types are free from misrea
