How to buy an original HHIP Granite Surface Plate in India?

All customs duties and Indian import taxes are pre-paid by crowcrowcrow and included in the listed INR price. This HHIP Granite Surface Plate is sourced directly from authorized US retailers and authorized brand partners, ensuring authenticity. It is factory-sealed and imported per-order, delivered via ExpressBox tracked shipping to your Indian pincode.

What is the difference between Grade B and Grade 00 granite surface plates?

Grade B (Grade 1) granite surface plates, like this HHIP model, offer reliable accuracy suitable for standard tool room and workshop inspection tasks. Grade 00 plates provide extremely high-precision laboratory flatness tolerances, designed for controlled metrology rooms and master gauge setting, making them significantly more expensive and delicate.

Is this HHIP surface plate suitable for heavy machining in India?

No, this 6"x8"x2" Grade B plate is best suited for inspection, layout, and light assembly. Its size and accuracy level are not designed for heavy machining setups or supporting large, heavy components. For such applications, consider larger, thicker granite or cast iron plates with higher precision grades.

How should a precision surface plate be cleaned and maintained?

Clean the plate regularly with a dedicated waterless surface plate cleaner and lint-free wipes to remove debris without abrading the stone. Always keep the working surface shielded with a heavy-duty vinyl or wooden cover when idle to protect it from dust and damage.

Does this granite surface plate come with a calibration certificate?

Yes, this HHIP granite surface plate includes a certificate of inspection confirming it meets Federal Specifications GGG-P-463C. Please note that these certificates are not NIST traceable.

About this item

The HHIP 6" x 8" x 2" Granite Surface Plate, Grade B, provides a highly accurate reference surface for critical metrology tasks. Its precision-ground top surface ensures exceptional flatness, meeting Federal Specifications GGG-P-463C with an accuracy of +/-.0001". This plate is non-magnetic and non-conductive, making it a versatile tool for inspection, calibration, and layout work in Indian workshops.

This granite plate is engineered for measuring flatness and squareness, calibrating instruments, and setting up tools. It serves as a stable, non-marring work surface for assembling, inspecting, and marking parts. Unlike metal plates, granite's thermal stability minimizes measurement errors due to temperature fluctuations, crucial for precision work in varying Indian workshop environments.

Imported directly from authorized US retailers, this HHIP surface plate ensures authentic quality for your metrology needs. All customs duties and GST are included in the listed price. Delivery is handled via ExpressBox, providing tracked transit to your Indian pincode.

Key Features

The top surface of this plate is precision ground to achieve a high degree of flatness and the accuracy is +/-.0001". It is a Grade B (Grade 1) plate.
Granite surface plates meet or exceed Federal Specifications GGG-P-463C and it includes a certificate of inspection. (Note that these are not NIST traceable.)
Granite plates are used for measuring the flatness and squareness of other objects, laying out parts, calibrating instruments, setting up tools, checking parallelism and perpendicularity, and measuring heights with the use of a height gage.
They are also used as a work surface for assembling, inspecting, and marking parts. Non-magnetic and non-conductive.
Surface plates are offered by HHIP in various sizes, with different levels of flatness and accuracy and are checked by an auto collimator for overall accuracy assurance.

Why choose this product

Engineered for Precision Metrology

This HHIP granite surface plate is built for demanding metrology applications. Its dense, non-porous granite construction offers superior stability and resistance to warping compared to metal alternatives. The precision-ground surface, accurate to +/-.0001", ensures reliable measurements for flatness, squareness, and parallelism. It meets Federal Specifications GGG-P-463C, providing a trusted reference standard for quality control and instrument calibration in your workshop.

Ideal for Indian Workshops, Not for Heavy Machining

This plate is perfect for inspection, layout, and light assembly in Indian workshops. However, its compact 6"x8" size and Grade B accuracy make it unsuitable for heavy machining setups or as a primary work surface for large, heavy components. For industrial-scale machining or applications requiring extreme load-bearing capacity, larger, thicker granite or cast iron plates with higher grades would be necessary.

How to use

Ensure the plate is placed on a stable, level surface. Clean the granite surface thoroughly with a dedicated surface plate cleaner and lint-free cloth to remove any dust or debris before use. — Prepare the Surface
Use the plate as a reference for measuring flatness and squareness of other objects. Place instruments like height gauges or dial indicators directly on the surface for accurate readings. — Perform Measurements
Utilize the plate for calibrating measuring instruments and setting up tools. Its stable, non-magnetic surface is ideal for inspecting parts and ensuring parallelism and perpendicularity. — Calibrate and Inspect
When not in use, cover the working surface with a heavy-duty vinyl or wooden cover to protect it from dust, accidental damage, and potential contamination. — Protect When Idle
