About CNC Granite Surface Plate

CNC Granite Surface Plate is a high-precision inspection and mounting platform specially designed for CNC machines and high-accuracy applications. It is manufactured from premium quality natural black granite and processed using advanced CNC technology to achieve superior flatness, parallelism, and dimensional accuracy.

The surface is finely lapped and calibrated to meet international standards, ensuring precise measurement and stable support for sensitive equipment. Granite material is non-magnetic, rust-free, and highly resistant to wear and deformation.

Due to its excellent thermal stability and vibration damping properties, CNC Granite Surface Plates are ideal for mounting CNC machines, inspection systems, and precision instruments.

Applications:

CNC Machine base and support
Precision inspection and measurement
Tool setting and calibration
Quality control labs

Key Features:

High precision CNC machined surface
Excellent flatness and parallelism
Rust-free and non-corrosive
High wear resistance
Vibration damping
Low maintenance and long life

Unmatched Precision and Stability

Engineered from high-quality black granite, these plates maintain flatness up to 2 microns per meter, essential for high-accuracy measurement and inspection. The three-point support system further reinforces stability, while the dense granite composition guarantees no fluid absorption or corrosion, outlasting traditional cast iron options and ensuring years of reliable service.

Customizable Options for Every Requirement

Available in a comprehensive range of sizes from 300x300 mm to 3000x2000 mm, the surface plates can be tailored to suit distinct inspection tasks. Optional threaded inserts, T-slots, lifting holes, and adjustable stands allow users to configure the plate for maximum efficiency and practicality, supporting various workpieces and instruments in demanding industrial settings.

FAQ's of CNC Granite Surface Plate:

Q: How does the high-quality black granite benefit CNC granite surface plates?

A: High-quality black granite provides an ultra-stable, non-magnetic, and corrosion-resistant surface. Its density reduces vibration, while its non-porous nature ensures no fluid absorption. This composition maintains flatness and precision over time, demanding less maintenance compared to metals.

Q: What processes are CNC granite surface plates typically used for?

A: CNC granite surface plates are fundamental in precision measurement, calibration, marking, and coordinate measuring machine (CMM) usage. They provide a stable, accurate base for inspecting machined components or setting up CNC equipment, as well as for certified dimensional standards.

Q: When should I consider using a granite surface plate over other materials?

A: A granite surface plate is ideal when your inspection or measurement tasks demand high accuracy, dimensional stability, and non-magnetic or corrosion-resistant attributes. Applications in temperature-controlled environments (18C-22C) that require minimal expansion and long-term precision are best served by granite plates.

Q: Where can these granite surface plates be installed or used?

A: These plates are suitable for use in inspection rooms, CNC machine shops, laboratories, or calibration centers-any environment where precision, humidity control, and stability are critical. Their usage spans across quality assurance departments and metrology labs.

Q: How is the flatness tolerance of the plate ensured and measured?

A: Flatness tolerance is maintained through meticulous lapping and inspection processes, meeting DIN 876/00 or equivalent standards (up to 2 microns per meter for higher grades). Final verification uses precision instruments, ensuring ultra-smooth surfaces aligned with client specifications.

Q: What optional accessories are available, and how do they enhance usability?

A: Accessories such as threaded inserts, T-slots, lifting holes, and steel or granite stands can be supplied. These additions facilitate mounting of fixtures, ease in transportation, and ergonomic positioning, enhancing workflow efficiency during inspection or measuring operations.

Q: What are the maintenance requirements and long-term usage benefits?

A: The granite plates are largely maintenance-free, requiring only periodic wiping and inspection. Their hardness (6-7 Mohs), non-magnetic character, and corrosion resistance deliver extended operational life, ensuring consistent accuracy and reducing long-term ownership costs.
