High Precision Granite Gauges and Measuring Tools from China Suppliers and Factory for Quality Assurance
V-blocks
- The necessary inspection tool for detecting concentricity and straightness with round bar.
- Suitable for materials used in clamps.
- One set contains two V-blocks.
- A necessary jig for processing 45˚ angle.
Granite master square
The granite square master is used to check the verticality between the Y axis and Z axis, the X axis and Z axis of the working machine, and the parallelism between the Y axis and the machine bed.
- For checking and calibrating the relative accuracy of the X, Y, Z axial on precision machine.
- Detect or calibrate the parallelism, straightness of working pieces.
- Axial correction and inspection of machine bed.
Calibration cub
- Vacuum pumps.
- Compressors in air-conditioning units.
- Refrigerating units and compressors.
- Biotech workstations.
- Drones.
- Automotive applications.
Parallel gauge
- The parallel gauge can be used to replace the pad block. With its own high precision, the user can raise the workpiece on the detection platform to detect the flatness and parallelism of the workpiece or machine tool table, guide rail and so on.
- Especially suitable for irregularly symmetric shaped workpieces.
We can make customized products.
Granite straight edge
Straight edges are used for checking of straightness, parallels, and flatness of machine tools, measuring machines and work pieces. Straight edges are very useful for layout and positioning of work pieces on precision surface plates.
- For measuring straightness and flatness.
- 2 surfaces or 4 surfaces with accuracy.
Granite Tri-square Master
- For measuring various angles of parts, working machine, etc.
- The size above 250*160mm are with holes to reduce the weight and it’s easier for users to take it.
Granite Surface plates
Many laboratories and shops rely specifically on granite surface plates for precise measurement and inspection. They are extremely accurate and stable due to the black granite material, providing a reliable reference point for measurements. Every measurement depends on an accurate surface reference from which dimensions are taken, and granite plates offer the perfect base for gaging surfaces and making accurate height measurements.
Granite Check Indicator Stand / Granite base with screw thread insert
Granite Check Indicator Stand/Granite base in various size and accuracy. Screw thread insert size can be indicated.
- Measuring dimension along with gauge blocks, dial indicators, or electronic probes.
- We can manufacture general gauge blocks or L-shaped blocks according to customers’ requirement for measuring.
Customized measuring tools
- For measuring objects in different shapes.
- For measuring non-ordinary verticality, parallelism or flatness.
- Customers can provide us the measurement points, and we design and produce special measuring tools for customers.
Reed type Mechanical Comparator
- The working principle of Reed type Comparator is similar to dial indicator and dial indicator.
- Reed type Comparator is a type of indicator without mechanical friction amplification mechanism.
- The diameter of reed type comparator is larger than that of a normal dial indicator (the diameter of the dial is about 70mm), and it is easy to read the value.
- The minimum division value is 0.5μm.
Frequently Asked Questions
What are the key applications of Granite Surface Plates?
Granite surface plates are widely used in laboratories and shops for precise measurement and inspection. Made from black granite, they provide an extremely accurate and stable reference plane, serving as a reliable base for height measurements and gaging surfaces.
How is a Granite Master Square used for machine calibration?
A granite square master is utilized to inspect and calibrate the verticality between the X, Y, and Z axes on precision machines. It also helps check the parallelism between the Y-axis and the machine bed, ensuring the machine's overall axial accuracy.
What are the benefits of using a Parallel Gauge?
Parallel gauges can replace standard pad blocks. Thanks to their high precision, they allow users to raise workpieces on a detection platform to accurately check the flatness and parallelism of both the workpiece and the machine tool guide rails. They are especially suitable for irregularly symmetric workpieces.
Why do larger Granite Tri-square Masters feature built-in holes?
For Granite Tri-square Masters with dimensions exceeding 250*160mm, holes are incorporated into the design to reduce weight. This makes the tools significantly lighter and much easier for operators to handle safely.
What makes the Reed type Mechanical Comparator unique?
The Reed type Comparator is an indicator designed without a mechanical friction amplification mechanism. It features a larger dial diameter (approximately 70mm) for easy reading and delivers a high-precision minimum division value of 0.5μm.
