[Case Study] Improved Effectiveness by Straightening the Pull Rod + Centerless Processing
Aluminum centerless grinding material
Is the aluminum material you are currently using really ◎? It is ideal for moving spindle CNC lathes, and its effectiveness is tremendous for parts with strict requirements for roundness and cylindricity.
Centerless grinding is a machining method used to process cylindrical materials. It is called "centerless" because grinding is performed without fixing the workpiece at the center, by passing it between two rotating grinding wheels. It is characterized by superior dimensional accuracy, surface roughness, and roundness compared to drawn materials. 【Adoption Example】 A6061B-T6: φ19×2500mm (Extruded rod) ⇒ φ18.9×2500mm (after centerless processing) Outer diameter tolerance: (±0.06) ⇒ (+0 -0.02) = By performing centerless grinding, a dramatic reduction in defect rates was observed in cutting processes. ⇒ (By performing correction processing, it becomes possible to improve surface accuracy with minimal cutting allowance.)

basic information
**Features of Aluminum Centerless Grinding Materials** - High precision across the entire length of long materials: Compatible with JISB0401 h5 class. - High bending accuracy: Exceptional correction technology reduces material bending to 4μm/100mm. - Ideal for spindle-moving CNC lathes, contributing to improved part accuracy, yield, and process reduction. **Benefits of Adoption** - Reduction of outer diameter dimension variation: Eliminates the need for pre-processing material by layer (sorting into tolerance plus and minus), allowing for direct processing. - Improved yield: With good material precision, the yield improves for parts that require higher accuracy. - Reduction of inspection processes: By consistently achieving precision, process capability dramatically improves, allowing for sampling inspections instead of full inspections. **Compatible Materials** A2017, A5052, A5056, A6061, A7075, etc. **Compatible Dimensions** Round bars and round pipes (consultation required for wall thickness), with outer diameter dimensions from φ1 to φ30 (correction processing is possible for φ1 to φ23).
