Precision Bearing Turning<\/strong><\/td>\nMachining internal and external diameters with precise running clearances (e.g., C3 fits) for high-speed shafts.<\/td>\nWe achieve roundness and concentricity within 0.01mm, ensuring smooth rotation and reduced heat generation in dry-running assemblies.<\/td>\n<\/tr>\n
Mirror-Finish Bore Grinding<\/strong><\/td>\nAchieving Ra 0.4\u03bcm surface finishes in internal bores to minimize friction and wear on mating metal shafts.<\/td>\nJucheng utilizes specialized diamond-honing tools to deliver the smooth surface required for high-RPM PEEK bearings.<\/td>\n<\/tr>\n
Micro-Grooving for Lubrication<\/strong><\/td>\nMilling spiral or longitudinal grease grooves for applications that utilize supplementary lubrication.<\/td>\nOur 4-axis milling capability allows for intricate internal groove patterns that enhance hydrodynamic lubrication and debris removal.<\/td>\n<\/tr>\n
Deep-Hole Boring<\/strong><\/td>\nDrilling and boring long-length bushings with high straightness and diameter consistency.<\/td>\nWe use specialized anti-vibration bars to prevent “tapering” in deep bores, ensuring the bushing supports the shaft evenly over its entire length.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Fabrication Guidelines for PEEK HPV<\/h3>\n

Abrasive Fillers:<\/strong>
\nThe carbon fiber and graphite content make PEEK HPV more abrasive than natural PEEK. Tipp:<\/strong> We use high-grade carbide or PCD (Diamond) tooling to prevent tool blunting, which can lead to friction-induced melting.<\/p>\n

Thermal Expansion Control:<\/strong>
\nWhile the fillers reduce overall expansion, the PTFE component reacts differently to heat. Tipp:<\/strong> We calculate “press-fit” tolerances carefully, accounting for the expansion difference between the HPV bushing and the surrounding metal housing.<\/p>\n

Cleanliness and Dust:<\/strong>
\nMachining HPV produces dark, fine dust. Tipp:<\/strong> We utilize high-vacuum extraction or wet-milling to protect the operator and prevent the conductive dust from settling on sensitive CNC electronic components.<\/p>\n

Workholding Stability:<\/strong>
\nHPV is quite rigid but can be brittle. Tipp:<\/strong> We avoid high-pressure chucking on thin-walled bushings to prevent micro-cracking, using collets or custom mandrels for final finishing passes.<\/p>\n<\/div>\n

Hauptanwendungen<\/h3>\n

Industrial Pump Components<\/strong>
\nWear rings, bushings, and thrust plates in chemical pumps where dry-run conditions or lack of lubrication may occur.<\/p>\n

Luft- und Raumfahrt & Verteidigung<\/strong>
\nActuator bearings and fuel system seals that must operate reliably without external grease in extreme temperatures.<\/p>\n

Lebensmittel- und Getr\u00e4nkeverarbeitung<\/strong>
\nChain guides and scraper blades in high-speed bottling or conveyor lines requiring FDA-compliant self-lubrication.<\/p>\n

Automobil-Antriebsstrang<\/strong>
\nTransmission thrust washers and shift fork pads that reduce friction and extend the service life of internal gearbox components.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
