Comprehensive High-Precision Product Portfolio and Practical Metrology Applications

SINCERE PRECISION supplies a wide variety of granite foundations and measuring instruments that suit various metrological and machinery applications. The precision granite products manufactured by SINCERE PRECISION directly tackle some of the physical problems in quality control.

Precision Structural Bases and Plates for Advanced Equipment Foundations

Precise machinery requires stable physical foundations to ensure dynamic repeatability and avoid spatial measurement errors.

• Granite Surface PlateSolutions: As a granite surface plate supplier, SINCERE PRECISION offers Grade 00 and Grade 0 inspection plates that serve as the main datum for quality control rooms and coordinate measuring machine setup. Each granite surface plate for metrology offers a stable reference plane for accurate dimensional inspection.
• Custom Precision Machine Foundations: As a CMM granite basesupplier, SINCERE PRECISION produces custom precision granite machine base constructions and granite bases for CMM applications specifically designed to dissipate dynamic motion vibration.
• Complex Structural Machine Parts: The granite metrology components offered by SINCERE PRECISION include custom gantry beams, crossrails, pillars, and air bearing guide rails for laser cutters, optical benches, and semiconductor stages. Such custom precision granite components can be produced according to the specific machine design.
• Addressing Manufacturing Challenges: The use of a granite surface plate for metrology instead of a welded steel bed eliminates thermal drift, reduces tool chatter, and prolongs equipment recalibration periods.

High-Accuracy Granite Measuring Tools for Shop Floor and Laboratory Calibration

For accurate dimension verification and axis alignment, shop floor granite gauges have better wear resistance compared to their steel gauge equivalents. As a specialized manufacturer of granite measuring instruments, SINCERE PRECISION manufactures calibration and alignment reference gauges.

• Granite Straight Edge: Made by a granite straight edge manufacturer, these gauges create super flat line references for checking the straightness of machine tool guide ways.
• Granite Master Square & Triangular Square: Designed by a granite master square manufacturer, these gauges are 90° right-angle gauges for checking perpendicularity on X, Y, and Z axes of CNC milling machines and CMM systems.
• Granite Square Box / Reference Cube: Made by a professional granite square box manufacturer, these 3D reference gauges offer perpendicular faces for complex workpiece calibration.
• Applications: In humid or magnetic conditions where steel gauges warp and rust, non-magnetic and rust-free stone gauges ensure verticality and parallelism verification without any anti-rust oiling.

Advanced Manufacturing Technologies, OEM Services, and Global Delivery

SINCERE PRECISION combines leading-edge stone processing machinery with strict climate-controlled quality management procedures. Full OEM manufacturing facilities provide for the complete delivery of OEM precision granite parts from design through international installation.

Sub-Micron Processing Capabilities and Climate-Controlled Production

Nanometer-order geometry demands special environmental conditions and multi-axis processing capabilities.

• Constant Temperature Processing Environment: Final lapping and micro-grinding are performed in specially prepared clean workshops, where the temperature control is kept at a constant 20°C ±2°C.
• Application of Heavy-Duty Cutting Machine Tools: The initial shaping of raw Jinan Black stone blocks is done by means of heavy-duty granite CNC cutting machines – special primary saws used only for stone block extraction.
• Hardware Capabilities: The precision diamond drilling, T-slot milling, and epoxy bonding allow mounting stainless steel threaded inserts, linear scale mounts, and air flotation passages in precision granite machine base structures.

FAQ

Q: Why does natural Jinan Black granite offer more advantages over cast iron or steel in making CMM bases and metrology inspection tools?

A: Natural Jinan Black granite has an extremely low coefficient of thermal expansion, 15-20 times the damping properties of steel, and total resistance to rusting, magnetization, and burr formation, providing long-term stability at the micron level for granite metrology parts and CMM structures.

Q: How do changes in temperature and humidity impact the accuracy of precision granite surface plates used for shop-floor inspection?

A: Although granite exhibits much better thermal stability compared to metals, in cases of extreme temperature differences, there may be slight expansion. Using Grade 00 surface plates in controlled 20°C environments and performing 3-point leveling will help avoid any flatness changes.

Q: What special care must be taken to maintain the Grade 00 accuracy of granite measuring tools?

A: No antirust oil is needed for granite tools. Every day, clean the working surface of the tool with a special residue-free surface plate cleaner; do not use any harsh alkaline soaps, and cover the top surface with vinyl covers.

Q: Can customized pre-installed threaded inserts and air flotation guide rails be integrated directly into granite structural bases?

A: Yes. Precision CNC diamond drilling and slotting can enable the integration of stainless steel threaded inserts, T-slots, and frictionless air-bearing guide surfaces using high-strength epoxy resin into custom precision granite components.
