A micrometer dial on a lathe is a precision measuring tool used to provide accurate and fine adjustments to the position of the cutting tool or workpiece. It typically features a rotating dial with a graduated scale, allowing the operator to read measurements in small increments, often in thousandths of an inch or millimeters. This enhances the lathe's capability for precision machining, enabling detailed work and ensuring high-quality finishes on turned parts. The micrometer dial is essential for tasks requiring accuracy, such as threading or creating intricate designs.
no you need a dial indicator
A machinist such as a lathe operator would use a micrometer caliper for precise measurements of the product he is machining, Also used by designers of precision parts and programmers of precision machines.
The chasing dial on a lathe is used to assist in producing threads without the need for a thread-cutting tool. It allows the operator to engage and disengage the lead screw at precise intervals to create threads on the workpiece.
That would be .65, as in "The micrometer reads 0.65 on the dial."
You would need a brake lathe and a micrometer. Use the micrometer to measure the thickness and then if there up to spec, use a brake lathe. Or simply just take them to your local parts dealer or mechanic (costs around $15.00) + I always get a second opinion on the "micrometer" interpretation by the shop- most want to sell a rotor and err on the side of loss of thickness. NAPA turns them for $5.00. Depending on your locale I am guessing you use different terminology... yet "turning" rotors is generally the term in the south. 2Dynamic
It is possible and often done. The best way to do it though would be to grip the rotor in a way that both sides can be machined without removing it from the lathe before its done. It will have to be set-up and aligned with a dial indicator from the inside faces of the hub.
The caliper and micrometer use a dial or digital readout to measure the distance between the tips. The tolerances of these tools can be under .001 inch, making them extremely accurate.
I think you mean a drum micrometer, but I could be wrong. A drum micrometer is really a dial or digital caliper that checks the wear on a break drum on a car. The wear on a drum is on the inside of the drum and is checked by the ID (inside diameter) with the tool, a micrometer for the most part checks the OD (outside diameter) of something. The most accurate way of testing ID is with a spring loaded pin rod, then check the pin distance with a micrometer.
A micrometer is equal to exactly 1 micrometer.
The best tools for measuring oil clearance on crankshaft bearings are typically a micrometer and a dial indicator. A micrometer is used to measure the thickness of the bearing shell and the journal, while a dial indicator can help check for any runout or irregularities. Additionally, plastigage can be used as a quick and effective method to measure oil clearance by providing a visual indicator of the gap between the bearing and journal.
