Delrin AF Machining Capabilities<\/h3>\n\n\n\n\n\n\n\n\n
Capability<\/th>\nTechnical Description<\/th>\nJucheng Advantage<\/th>\n<\/tr>\n<\/thead>\n
Ultra-Smooth Bore Turning<\/strong><\/td>\nMachining internal bearing diameters to Ra 0.4\u03bcm to maximize the self-lubricating effect of the PTFE fibers.<\/td>\nWe utilize specialized diamond-polished inserts to ensure the Teflon fibers are sheared cleanly, creating a slippery, low-friction interface.<\/td>\n<\/tr>\n
Precision Thrust Washer Milling<\/strong><\/td>\nMilling thin, flat washers with strict parallelism (+\/- 0.02mm) to prevent uneven wear in rotating assemblies.<\/td>\nOur vacuum workholding systems ensure that thin Delrin AF plates remain perfectly flat during high-speed milling operations.<\/td>\n<\/tr>\n
Complex Low-Friction Cams<\/strong><\/td>\nUsing 4-axis CNC milling to create intricate cam profiles that operate without external grease.<\/td>\nJucheng’s precision ensures smooth profile transitions, reducing mechanical noise and stick-slip vibration in automated machinery.<\/td>\n<\/tr>\n
High-Volume Bushing Production<\/strong><\/td>\nRapid production of self-lubricating bushings using automated bar-fed Swiss lathes.<\/td>\nOffers high-speed output with extremely consistent dimensions, making Delrin AF a cost-effective alternative to lubricated bronze.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Fabrication Guidelines for Delrin AF<\/h3>\n

Distinctive Appearance:<\/strong>
\nDelrin AF is typically dark brown or chocolate in color due to the PTFE fibers. Tip:<\/strong> This makes it easily distinguishable from standard white or black POM during assembly and inspection.<\/p>\n

Cutting Temperature:<\/strong>
\nWhile the PTFE fibers provide lubrication, heat buildup can still cause material softening. Tip:<\/strong> We use sharp tools and high-volume air blast or water-soluble coolant to keep the material rigid for accurate cutting.<\/p>\n

Avoid Bonding:<\/strong>
\nDue to the high Teflon content, Delrin AF is almost impossible to glue or bond. Tip:<\/strong> Design your assembly using mechanical fasteners or interference (press) fits.<\/p>\n

Environmental Stability:<\/strong>
\nLike all acetals, Delrin AF has very low moisture absorption. Tip:<\/strong> It maintains its precise dimensions even in submerged or high-humidity environments, unlike Nylon.<\/p>\n<\/div>\n

Primary Applications<\/h3>\n

High-Speed Sliding Bearings<\/strong>
\nBushings and sleeves in office equipment and conveyors that must operate silently without liquid lubricants.<\/p>\n

Medical & Laboratory Equipment<\/strong>
\nMoving parts in diagnostic machines where grease contamination would ruin sensitive samples or sensors.<\/p>\n

Consumer Electronics<\/strong>
\nInternal sliding mechanisms for cameras, lens actuators, and high-end audio-visual equipment.<\/p>\n

Industrial Automation<\/strong>
\nGuide rails, wear strips, and cam followers that require long-term durability and a low “breakaway” force.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
