What is a Sunnen gage?

What is a Sunnen gage?

The Sunnen PG Bore Gaging System is a unique mechanical gaging system that makes bore I.D. The dial bore gages feature all-carbide gaging points, wear-proof ball crank, and adjustable centralizers. Available in a wide variety of models and ranges for use with virtually all Sunnen or other honing machines.

How accurate is a bore gauge?

When a dial bore gauge is set using a ring gauge, overall accuracy can be within 0.0001 inches or 0.00254 millimeter.

How do you set up a Sunnen gauge?

EASY TO SET – You only need one Sunnen Setting Fixture to set to any size in the CF-1126 range. It’s so easy! Just place the gage in the fixture, dial the size and rotate the gage dial to zero. You’re ready to go.

How do you calibrate a bore gauge?

The proper way to calibrate a bore gauge is to have a calibrated setting ring or a gauge block depending on your available equipment and device under test. The most common standard used is a master setting ring.

How does a bore gauge work?

A bore gauge is a tool used to measure the inside of a bore, or hole. Once a bore gauge is inserted into the hole that needs measuring, small parts called anvils expand outward to determine the diameter. Bore gauges with three anvils are called internal micrometers or tri mics, and are calibrated with setting rings.

What is the best tool to measure cylinder bore?

Dial bore gauges are the most used tool for measuring inside diameters and for a good reason. A dial bore gauge is easier to position than any other tool mentioned above and is very accurate.

What is the range of dial bore gauge?

18 – 50mm
Dial Bore Gauge: Range 18 – 50mm.

How do you validate a dial bore gauge?

Here are the steps to follow to read a dial bore gauge.

  1. Step1. Place the bore gauge in a micrometer locked to the same diameter of the hole being measured.
  2. Step2. After that, rotate the indicator’s dial until the pointer aligns with the “0” marking on the dial face.
  3. Step3.
  4. Step4.
  5. Step5.

When would you use a bore gauge?

Dial bore gauges are mostly used by machinists to measure the inner diameter of bores in motor engines. The speed and accuracy of a dial bore gauge can save a lot of time when used to measure cuts or hole sizes in home remodeling projects.

How do you zero a bore gauge?

Zero the gauge. This is accomplished by measuring across the gauge with an outside micrometer set to the precise bore size. When the zero aligns with the needle you’re ready. Insert the gauge into the bore to the depth you need.

What is least count of bore dial gauge?

Bore Gauge

Size in mm Least Count in mm
10-18 0.01/ 0.001
18-35 0.01/0.001
35-60 0.01/0.001
50-160 0.01/0.001

What kind of bore gaging system does Sunnen use?

Sunnen offers two distinctly different types of bore gaging systems–Sunnen PG Series Precision Bore Gages and Sunnen Dial Bore Gages, which cover nearly every bore size and configuration.

Can a Sunnen dial bore Gage be used with a Jo block?

Each gage comes packed in its own sturdy box with all tools and wrenches required for setup and adjustment. Sunnen Dial Bore Gages can be used in tandem with Sunnen Setting Fixtures for a complete system which eliminates the need for ring gages, micrometers or jo blocks.

What are the different types of bore Gages?

Unlike most other gages, Sunnen’s PG and Dial Bore models are rugged, accurate and designed for shop floor use with Sunnen or other bore sizing machines, and in QC or metrology settings. The Sunnen PG Bore Gaging System is a unique mechanical gaging system that makes bore I.D. gaging simple, reliable, and economical.

When do you need a dial bore Gage?

Dial bore gages are particularly handy when measuring bores in large workpieces when it is easier to measure the workpiece in place than to take the workpiece to a gaging station.
