FA B R I C ATION GU IDELINESThe following guidelines are presentedfor those machinists not familiar with themachining characteristics of plastics. Theyare intended as guidelines only and maynot represent the most optimum conditionsfor all parts. The troubleshooting quickreference guides in this booklet should beused to correct undesirable surface finishesor material responses during machiningoperations.4All Mitsubishi Chemical Advanced Materialsare stress relieved to ensure highest degreeof machinability and dimensional stability.However, the relative softness of plastics(compared to metals) generally results ingreater difficulty maintaining tight tolerancesduring and after machining. A good rule ofthumb for tolerances of plastic parts is /.001 per inch of dimension although tightertolerances are possible with very stable,reinforced materials.When Machining MitsubishiChemical Advanced MaterialsStock Shapes Remember.Getting Started T hermal expansion is up to 10x greaterwith plastics than metals Carbide tooling with ground top surfacesis suggested for optimum tool life andsurfaces finish. Polycrystalline diamondtooling provides optimum surface finishwhen machining Duratron PBI. P lastics lose heat more slowly thanmetals, so avoid localized overheating S oftening (and melting) temperaturesof plastics are much lower than metals P lastics are much more elastic thanmetalsBecause of these differences, you maywish to experiment with fixtures, toolmaterials, angles, speeds and feed ratesto obtain optimum results. P ositive tool geometries with groundperipheries are recommended U se adequate chip clearance to preventclogging A dequately support the material torestrict deflection away from thecutting tool
CoolantsMachining TipsCoolants are generally not required formost machining operations (not includingdrilling and parting off). However, foroptimum surface finishes and closetolerances, non-aromatic, water solublecoolants are suggested. Spray mists andpressurized air are very effective means ofcooling the cutting interface. Generalpurpose petroleum based cutting fluids,although suitable for many metals andplastics, may contribute to stress crackingof amorphous plastics such as Altron PC1000, Sultron PSU, Duratron U1000 PEI,and Sultron PPSU.Coolants are strongly suggested duringdrilling operations, especially with notchsensitive materials such as Ertalyte PET-P,Duratron PAI, Duratron PBI and glass orcarbon reinforced products.In addition to minimizing localized partheat-up, coolants prolong tool life. Two(flood) coolants suitable for most plasticsare Trim E190 and Trim Sol LC SF (MasterChemical Corporation – Perrysburg, OH).5
FA B R I C ATION GU IDELINESThreading & TappingMillingThreading should be done by single pointusing a carbide insert and taking four tofive 0.001 passes at the end. Coolantusage is suggested.Sufficient fixuring allows fast table traveland high spindle speeds when end millingplastics. When face milling, use positivegeometry cutter bodies.For tapping, use the specified drill with atwo flute tap. Remember to keep the tapclean of chip build-up. Use of a coolantduring tapping is also suggested.SawingUse of a coated tap can improve thetoughness of threads in a notch sensitivematerial.6Band sawing is versatile for straight,continuous curves or irregular cuts. Tablesaws are convenient for straight cuts andcan be used to cut multiple thicknessesand thicker cross sections up to 4 withadequate horsepower. Saw blades shouldbe selected based upon material thicknessand surface finish desired.
Sawing Tips R ip and combination blades with a 0ºtooth rake and 3º to 10º tooth set arebest for general sawing in order toreduce frictional heat. H ollow ground circular saw bladeswithout set will yield smooth cuts upto 3/4 thickness. T ungsten carbide blades wear welland provide optimum surface finishes.7
DR I LL I NGThe insulating characteristics of plasticsrequire consideration during drillingoperations, especially when hole depthsare greater than twice the diameter.Small diameter holes (1/32 to1 diameter)High speed steel twist drills are generallysufficient for small holes. To improve swarfremoval, frequent pulling out (peck drilling)is suggested. A slow spiral (low helix) drillwill allow for better swarf removal.Large diameter holes (1 diameter & larger)8A slow spiral (low helix) drill or generalpurpose drill bit ground to 118º pointangle with 9º to 15º lip clearance isrecommended. The lip rake should beground (dubbed off) and the web thinned.It is generally best to drill a pilot hole(maximum 1/2 diameter) using 600 to1,000 rpm and a positive feed of 0.005 to0.015 per revolution. Avoid hand feeingbecause of the drill grabbing which canresult in microcracks forming. Secondarydrilling at 400 to 500 rpm at 0.008 to 0.020 per revolution is required to expand thehole to larger diameters.A two step process using both drillingand boring can be use on notch sensitivematerials such as Ertalyte PET-P and glassreinforced materials. This minimizes heatbuild-up and reduces the risk of cracking.Tech Tip: 1. D rill a 1 diameter hole using aninsert drill at 500 to 800 rpm witha feed rate of 0.005 to 0.015 perrevolution.2. Bore the hole to final dimensionsusing a boring bar with carbideinsert with 0.015 to 0.030 radii at500 to 1,000 rpm and a feed rate of0.005 to 0.101 per revolution.
TurningTurning operations require insertswith positive geometries and groundperipheries. Ground peripheries andpolished top surfaces generally reducematerial build-up on the insert, improvingthe attainable surface finish. A fine grainedC-2 carbide is generally best for turningoperations.9

ANN E A LIN GWhen should parts beannealed after machiningto ensure optimum partperformance?Experience has shown us that very fewmachined plastic parts require annealingafter machining to meet dimensional orperformance requirements.All Mitsubishi Chemical AdvancedMaterials’ stock shapes are annealedusing a proprietary stress relieving cycleto minimize any internal stresses that mayresult from the manufacturing process.26This assures you that the material willremain dimensionally stable during andafter machining.Machined-in stress can reduce partperformance and lead to premature partfailure. To prevent machined-in stress, it isimportant to identify the causes.Machined-in stress iscreated by: U sing dull or improperly designedtooling E xcessive heat – generated frominappropriate speeds and feed rates M achining away large volumes ofmaterial – usually from one side of thestock shapeTo reduce the potential formachined-in stress, review thefabrication guidelines for the specificmaterial. Recognize that guidelineschange as the material type changes.
P O ST M ACHI NI NGBenefits of Post-Machining AnnealingImproved ChemicalResistanceBetter Flatness and TighterTolerance CapabilityPolycarbonate, polysulfone, and Duratron PEI, like many amorphous (transparent)plastics may be annealed to minimizestress crazing. Duratron PAI also benefitsfrom post machining annealing. Annealingfinished parts becomes more important asmachining volume increases. Annealingafter machining reduces machined-in stresses that can contribute to prematurefailure.Extremely close–tolerance parts requiringprecision flatness and non-symmetricalcontour sometimes require intermediateannealing between machining operations.Improved flatness can be attained by roughmachining, annealing and finish machiningwith a very light cut. Balanced machiningon both sides of the shape centerline canalso help prevent warpage.Improved Wear ResistanceExtruded or injection molded Duratron PAI parts that require high PV’s or thelowest possible wear factor benefit from anadditional cure after machining. This curingprocess optimizes the wear properties.Only Duratron PAI benefits from such acycle.27

Thermoplastics & ThermosetsPlastics are commonly described as beingeither a thermoplastic (meltable) or athermoset (non meltable). Thermosetmaterials such as phenolic and epoxy weredeveloped as early as 1900 and were someof the earliest high volume plastics. Boththermoplastic and thermoset stock shapesare available for machined parts, althoughthermoplastic stock shapes are much morecommonly used today. Their ease offabrication, self-lubricating characteristics,and broad size and shape availability makethermoplastics ideal for bearing and wearparts as well as structural components.39
