   1. In-depth Custom Demand Communication & Plan Finalization
   The premise of custom processing is to accurately meet customers' personalized working requirements, avoiding after-sales troubles such as dimensional errors, mismatched structures and inadequate precision. Drawing on years of experience manufacturing ultra-precision components, our team fully verifies key information provided by clients, including equipment drawings, installation space, load parameters, precision grades and service environments.
   We confirm critical specifications: length, width and thickness of the base, quantity, pitch and depth of T-slots, mounting hole positions, flatness tolerance, shockproof and moisture-proof requirements. Meanwhile, we match appropriate machining and calibration standards according to application scenarios, such as semiconductor workshops, precision inspection labs and automated production lines.
   For special custom orders including ultra-heavy, extra-long and special-shaped slots, our technical team optimizes machining schemes, equipment selection and hoisting schedules separately. We deliver exclusive process plans and production drawings, complete technical disclosure and parameter confirmation. Deviations are eliminated from the very beginning to guarantee full compatibility with clients' on-site conditions.
   2. Selection of Exclusive High-Grade Substrates & Aging Preprocessing
   Long-term stability of granite bases hinges on substrate quality, which is the fundamental guarantee of lasting precision for custom products. We reject inferior materials including ordinary marble and low-density variegated granite. All custom metal T-slot granite bases adopt UNPARALLELED® self-developed high-density black granite with a density of 3100kg/m³. Its physical properties surpass black granite imported from Europe and America, featuring compact impurity-free texture, ultra-low water absorption, low thermal expansion coefficient, high rigidity and excellent wear resistance. It resists deformation caused by temperature & humidity fluctuations and continuous heavy loads over decades.
   All raw stones are stored in a dedicated 20,000 ㎡ stone yard for long-term natural aging to fully release inherent internal stress, preventing warpage, deformation and precision attenuation in later use. Technicians select qualified blanks according to product weight and dimensions, eliminating raw stones with cracks, pores and impurities. Layered precision cutting reserves reasonable machining allowance to balance precision and material utilization, laying a solid foundation for subsequent integral forming and precise T-slot machining.                                                                                                     Custom Grooving Process For Granite Air Bearings To Ensure Uniform Airflow And Stable Long-Term Air Pressure Output
   3. Integral Rough Machining & Multi-Stage Stress Relief for Shaping
   Equipped with full sets of heavy-duty processing equipment in two standardized factories covering a total area of 200,000 ㎡, we conduct integral rough machining for custom bases up to 100 tons and 20 meters long. We abandon the outdated segmented splicing process widely adopted in the industry, fundamentally eliminating hidden risks such as uneven stress at joints and dislocation deformation in service. Large CNC machines and heavy-duty silent overhead cranes work together to complete rough milling of base outlines, basic holes and reserved slots in one clamping.
   Symmetrical reciprocating cutting paths evenly release mechanical cutting stress to prevent plate bending and edge breakage caused by unbalanced unilateral force. After rough machining, multiple static stress relief cycles eliminate secondary processing stress, solving the common industry defect where granite products pass inspection after machining yet rebound and deform later, and locking the basic structural stability of each base.
   4. Precision T-Slot Forming & Metal Fitting Process under Constant-Temperature Conditions
   Metal T-slots are the core functional structure of custom granite bases, directly determining fixture positioning accuracy and assembly stability, and standing as the biggest difficulty in custom machining. All finish milling, slotting and metal strip embedding procedures are completed in our 10,000 ㎡ constant-temperature, humidity-controlled, shockproof and dust-free workshop. The workshop floor is poured with 1000mm-thick ultra-hard concrete and surrounded by double shock isolation trenches, isolating all external interference from vibration, temperature difference and dust to guarantee micron-level precision during slot machining.
   We deploy Taiwan Nante ultra-large precision grinders and high-precision CNC slot milling machines. Low-speed layered finish milling is performed based on custom slot parameters, with strict control over perpendicularity, parallelism, notch flatness and pitch tolerance of T-slots to avoid vibration offset and edge chipping during long-distance slotting. After slot forming, precise edge trimming and polishing are carried out, followed by seamless embedding, fastening and calibration of metal fittings. The finished metal T-slots feature uniform stress distribution, accurate positioning and zero loose gaps, suitable for frequent fixture disassembly and long-term heavy-load operation.
   5. Nano-Level Manual Polishing by Senior Craftsmen & Full-Range Precision Calibration
   After mechanical precision machining, veteran grinders with over 30 years of industry experience conduct refined manual treatment. The team is proficient in global precision metrology standards including German DIN, American ASME, Japanese JIS and Chinese GB. Relying on micron-level sensitive polishing touch, they perform nano-scale hand finishing on base tabletops, inner T-slot walls, edges and mounting reference surfaces, correcting tiny mechanical machining errors and optimizing table flatness and surface finish.
   We fine-tune reference precision according to personalized tolerance requirements of each custom order. The flatness, slot precision and parallelism of every granite base fully match client-specified standards, achieving delicate customized effects unattainable by mass-production equipment.
   6. Full-Dimensional Precision Inspection & Compliant Traceable Delivery
   We adhere to the core philosophy: only measurable work can be manufactured with high precision. Our full-process, all-round inspection system ensures every custom granite base meets precision standards with authentic, traceable test data. Equipped with world-class testing instruments including German Mahr dial gauges, full series of Mitutoyo measuring tools, Swiss WYLER electronic levels and UK Renishaw laser interferometers, we conduct multi-point micron and nano-level precision tests on core indicators: overall dimensions, flatness, parallelism, surface roughness, T-slot accuracy, hole position tolerance and geometric form errors.
   All testing instruments hold valid calibration certificates issued by municipal and provincial metrology institutes, and all precision data can be traced back to the National Institute of Metrology of China. Through long-term in-depth cooperation with the National University of Singapore and metrology institutes across the globe, we continuously upgrade customized precision inspection solutions and strictly benchmark against top-tier global precision standards. Products failing precision tests are prohibited from delivery, and complete inspection reports and qualification documents are provided for clients to satisfy acceptance standards of high-end laboratories, multinational corporations and export projects.
   7. Damage-Free Protection, Standardized Hoisting & Customized Delivery
   Custom granite bases feature oversized dimensions, ultra-high precision and fragile edges. We build a dedicated finished-product protection and delivery system. After manufacturing, products are cleaned dust-free and coated with surface protective layers. Special wrapping protection is applied to T-slots, precision reference surfaces and all edges to prevent abrasion, collision damage and dust adhesion during transportation.
   Exclusive hoisting and loading plans are formulated according to product size and weight. Multi-point balanced hoisting with flexible slings avoids deformation and invisible cracks caused by concentrated single-point stress. Professional heavy-duty equipment ensures stable loading and fixing to prevent precision damage from bumpy transit. We follow standardized delivery procedures and provide value-added services including installation guidance, precision re-testing and after-sales calibration to fully guarantee on-site application performance for customers.
