• 0 to 25 mm total measuring range covers the full travel distance needed for most machining runout, flatness, and comparative measurement tasks
• Overall accuracy of ±0.025 mm across the full range and ±0.01 mm accuracy for the first 2.5 revolutions meet professional quality control requirements
• Large 57 mm diameter dial face with clear 0–100 numbered scale and distinct red and black graduations allows fast, error-free reading from a comfortable working distance
• Rotating bezel with locking clamp lets users zero the indicator at any reference position without moving the instrument or workpiece
• Revolution counter on the dial face tracks total spindle travel so users always know how many full millimeters the plunger has moved
• 8 mm precision-ground stem fits all standard magnetic bases, dial indicator holders, lathe compound rests, and surface plate stands without adapters
• Lug back with mounting ears provides a second mounting method for comparator stands, gauge fixtures, and surface plate inspection setups
• Hardened and ground steel plunger spindle runs on precision jewel or ball bearings for smooth, consistent, and repeatable travel throughout the measuring range
• 5 threaded contact point accepts standard and specialty tips — flat, ball, knife-edge — for different workpiece surface geometries
• Shockproof internal mechanism protects the gear train and bearings against vibration from machine tools and occasional accidental contact during setup
• Compact and lightweight instrument design allows users to mount it in tight spaces inside machine tool fixtures and custom inspection gauges

Applications Dial gauge indicator 0.01-0.25mm

• Lathe and milling machine runout checking – Mounting the dial gauge on a magnetic base to measure radial and axial runout on chucks, collets, spindles, and arbors before starting precision turning or milling operations
• CNC machining centre setup – Checking machine table parallelism, spindle squareness, and fixture alignment so programmed dimensions translate directly into accurate finished parts
• Flatness and surface inspection – Sweeping the plunger across a surface plate, machine bed, or workpiece face to detect high spots, low areas, and twist that affect assembly and function
• Comparative dimensional inspection – Placing a reference gauge block under the plunger, zeroing the bezel, and comparing production parts against the reference to verify dimensional consistency within tolerance
• Jig and fixture alignment – Positioning clamps, locating pins, and support pads in welding fixtures, machining fixtures, and assembly jigs to the correct height and position before production begins
• Bearing and shaft runout measurement – Checking that shafts, bearing journals, and gear bores fall within specified roundness and concentricity tolerances to ensure smooth rotation and long service life
• Press and stamping die setup – Verifying die opening parallelism, punch height uniformity, and shut height consistency in stamping and forming presses to maintain part quality across production runs
• Incoming and outgoing quality control – Inspecting purchased raw material dimensions and finished component dimensions against engineering drawings before parts move to the next production stage or ship to customers

 

Who Uses This Dial gauge indicator 0.01-0.25mm

• Machinists and lathe operators in Bangladesh’s metalworking and engineering workshops who check chuck runout, tool overhang, and workpiece setup accuracy before every precision cutting operation
• CNC machine operators and programmers who verify machine table alignment, fixture location, and spindle runout to ensure programmed dimensions produce accurate finished parts

Frequently Asked Questions (FAQ)

Q: What does 0.01mm resolution mean on a dial gauge indicator?

A: Resolution of 0.01 mm means each graduation mark on the dial face represents a linear movement of exactly 0.01 mm at the plunger tip. When the pointer moves one division, the plunger has moved 0.01 mm. A full revolution of the pointer across the 100-division scale equals 1 mm of plunger travel. The Dial Gauge Indicator 0.01mm resolves measurements down to this 0.01 mm scale division, making it suitable for precision inspection work in machining, toolmaking, and quality control.

Q: What is the difference between 0.01mm and 0.001mm dial gauges?

A: The 0.01 mm dial gauge has one graduation per 0.01 mm of travel, which suits most machining runout checks, surface comparisons, and fixture alignments in general engineering workshops. The 0.001 mm (one-micron) dial gauge has ten times finer graduations and suits ultra-precision work in tool rooms, gauge calibration laboratories, and high-tolerance aerospace and medical device manufacturing. For most machining and quality control applications in Bangladesh, the 0.01 mm dial gauge indicator delivers adequate sensitivity at a more affordable price.

Q: How do I zero the dial gauge indicator?

A: Users mount the dial gauge in a holder or magnetic base, lower the plunger until it contacts the reference surface with the correct measuring force, then release the bezel locking clamp and rotate the bezel until the pointer aligns with the zero mark. Tightening the clamp locks the bezel in that position. The gauge now reads zero at the reference, and all subsequent readings show deviation from that reference — positive readings indicate the surface is higher than zero, negative readings indicate it is lower.

Q: What stem diameter does this dial gauge use and what stands does it fit?

A: The dial gauge indicator uses an 8 mm diameter precision-ground stem, which fits the vast majority of magnetic dial indicator bases, lathe compound rest holders, surface plate stands, and comparison gauge fixtures available in Bangladesh and internationally. The stem length of approximately 38 mm suits standard holder clamps. Users who need to reach into deep bores or recessed surfaces can purchase stem extension rods separately.

Q: Can I use this dial gauge on a lathe to check runout?

A: Yes. Checking lathe chuck and spindle runout is one of the most common uses of the Dial Gauge Indicator 0.01mm in Bangladesh’s machining workshops. The user mounts the gauge on a magnetic base or lathe tool post holder, touches the plunger to the outer diameter of the chuck or a test bar in the spindle, zeros the bezel, then rotates the chuck by hand through one full revolution. The maximum pointer deflection shows the total indicator reading (TIR), which equals the runout value.

Q: Does the dial gauge come with a magnetic base?

A: The standard package includes the dial gauge indicator, a contact point, lug back ears, and a protective storage case. The magnetic base and fine-adjustment holder are sold separately. ASTZ Bangladesh stocks compatible magnetic bases and dial gauge stands and offers bundle pricing for customers who need the complete measurement setup. Contact ASTZ for current bundle prices.

Q: What is the measuring force of this dial gauge?

A: The dial gauge applies approximately 2.0 N to 2.5 N (roughly 200 to 250 gf) of measuring force through the plunger onto the workpiece surface. This moderate measuring force suits rigid metal workpieces, machine surfaces, and gauge blocks. Users who measure soft materials such as rubber, foam, or thin sheet metal should choose a low-force gauge to avoid surface deformation under the plunger tip.
