UNPARALLELED LTD is one of the leading manufacturers and suppliers of integrated granite base in China. With abundant experience, we warmly welcome you to buy advanced integrated granite base made in China here from our factory. We also accept custom orders.
Product Overview
The integrated granite base is machined from a single‑piece high‑density black granite to provide an integrated mounting reference for complete equipment. T‑slots, mounting holes, wiring grooves and weight‑reducing cut‑outs can be directly machined on the monolithic body without multi‑part assembly. With a density of 3100kg/m³, it features low thermal expansion and high damping performance to mitigate micro‑vibration caused by temperature fluctuation and equipment movement. All precision working surfaces are ultra‑precision ground in a Class‑10,000 constant‑temperature, constant‑humidity and dust‑free workshop, with tightly‑controlled flatness, perpendicularity and positional accuracy. Embedded stainless steel thread inserts allow direct mounting of linear motors, optical modules and guide rails. Customized per customer drawings, certified by ISO management systems and CNAS traceable inspection, it is widely used in semiconductor equipment, high‑precision automatic production lines, laser machines and precision measuring instruments to secure long‑term system accuracy.

Quality Control
Main Application Fields of Integrated Granite Base
Semiconductor Inspection Equipment: Acts as the core base for wafer and chip inspection equipment, supporting linear motors and optical modules to resist temperature variation and vibration and ensure stable imaging and inspection.
High‑precision Automatic Production Lines: Used for high‑precision assembly and inspection stations, supporting 24‑hour continuous operation and providing highly‑stable mounting references.
Ultrafast Laser Processing Equipment: Carries lasers and motion components. The high‑damping property of granite restrains beam drift.
Ultra‑precision Measuring Instruments: Suitable for interferometers, industrial CT and CMM machines. Low thermal expansion reduces accuracy drift caused by ambient temperature change.
Scientific Research Experimental Devices: Serves universities and institutions including the Chinese Academy of Sciences for optical experimental platforms and precision test fixtures.
High‑end Intelligent Equipment: For various custom precision equipment. Integrated slots and holes eliminate cumulative errors from multi‑component assembly.
Product Advantages
Monolithically machined from single‑piece granite. T‑slots, wiring grooves and mounting holes are milled directly without multi‑part assembly to eliminate cumulative assembly errors. With density of 3100 kg/m³ and thermal expansion coefficient ≤3e‑6/℃, it features high damping to absorb vibration and minimizes deformation under temperature fluctuation.
Raw blanks undergo multi‑stage stress aging treatment to avoid micro‑deformation during service and deliver excellent long‑term precision retention.
Embedded stainless steel thread inserts instead of direct stone tapping. Resists thread wear during repeated disassembly and ensures stable mounting of optical components.
Precision working surfaces are ground in Class‑10,000 constant‑temperature, constant‑humidity dust‑free workshop with micron‑level flatness and perpendicularity. Rounded blended edges reduce chipping risks during handling and assembly.

Frequently Asked Questions
Q1: Are there standard stock products? A: No standard stock. All products are non‑standard customized per customer drawings, and accuracy grades can be adjusted as required.
Q2: Will integrated cut‑outs reduce base rigidity? A: Structure will be evaluated at design phase. Reasonable cut‑out layout with reinforcing features prevents insufficient rigidity.
Q3: Why adopt embedded stainless steel inserts instead of direct tapping on granite? A: Granite is brittle. Direct tapping may cause cracking and thread slipping. Embedded stainless steel inserts offer higher assembling strength for repeated mounting and dismounting.
Q4: What accuracy can be achieved? A: Flatness and perpendicularity of reference surfaces can reach up to 1 μm/m, with CNAS‑traceable test data.
Q5: What is the lead time? A: Lead time depends on dimension, cut‑out complexity and accuracy requirements. It covers multi‑stage stress aging, machining, grinding and inspection. Delivery time will be confirmed upon drawing review.
Q6: How to protect precision surfaces during shipment? A: Custom shock‑resistant solid‑wood packaging is applied. Large‑size bases are fitted with lifting inserts. Rounded edges reduce chipping risks. Inspection reports are supplied together with goods.
Q7: What should be noted in application? A: Avoid long‑term contact with strong acids and alkalis. Control screw tightening torque to prevent stress‑induced stone deformation. Knocking against ground working surfaces is prohibited.
