Frequently Asked Questions

If you want to know more about POM (Delrin/Acetal) CNC Machining

Q: Why is POM considered an ideal material for CNC machining?

A: When it comes to CNC machining, POM or delrin or acetal is a favorite choice because it has good mechanical properties, high rigidity and low friction. Such features make this material applicable for precision components that need dimensional stability and wear resistance.

Q: Can POM be used in making both metal and plastic machine parts within CNC machining?

A: Absolutely! POM is a versatile engineering thermoplastic used for precision parts in both metal and plastic machine elements. Excellent dimensional stability together with mechanical properties of this kind allow it to work well in applications traditionally served by metals but at lighter weight and with corrosion resistance as bonus benefits.

Q: What are the main properties of POM that make it better for CNC machined parts than any other material?

A: The key features exhibited by POM include excellent dimensional stability, high strength (mechanical), low friction as well as superior wear resistance. These qualities which also resist creep while maintaining accuracy over time makes them highly desirable when selecting materials for use in CNC machined parts.

Q: How does designing with POM differ from designing with other materials on a CNC machine?

A: In most cases designers have to take into account some unique characteristics of the material being worked namely; high stiffnesses coupled with low frictions may require considering tool geometry or cutting angles so that too much heat isn’t generated during processing thereby leading to deformation. Additionally pathing or coolants should be applied cautiously so as not cause overheating which can distort dimensions due thermal expansion/contraction effects caused by these substances when used improperly.

Q: What are the benefits of using POM instead of metal in CNC machining?

A: Compared to metals lower costs per unit mass combined with less abrasive hardness gives machines longer life spans but still produce same quality finishes; moreover lighter weights will reduce production times especially where there’s need for transportation during assembly stages besides inherent corrosion resistance properties mean no rusting occurs over time. Additionally for certain applications there is better wear resistance exhibited by this polymer due its low moisture absorption rate and good surface finish in contact with other moving parts.

Q: What kinds of projects or components are suitable for machining POM by CNC?

A: The most appropriate projects or components for POM CNC machining include those needing high precision, very good wear resistance and dimensional stability. This involves gears, bearings, electrical engineering parts as well as those in the automotive and consumer electronics industries.

Q: When CNC Machining POM what challenges can be faced and how can they be solved?

A: Heat control which may cause material melting or deformation should be looked into among other challenges associated with CNC machining POM; correct chip removal must also be ensured so that clogging does not occur leading to tool wear. To address these problems one needs to optimize cutting parameters, employ proper coolant flow rates and choose suitable tools for working on POM.

Q: How do the accuracy of parts made through CNC machining using POM compare against those produced through traditional injection moulding?

A: Accuracy levels of CNC machined POM parts are often higher than those made via traditional injection molding because the former allows for tighter tolerances to be achieved while at same time giving room for more complex geometries without compromising mechanical properties of materials used. However, from an economic perspective it might turn out that only large scale production would justify use of injection moulding process.

Q: Are there any special maintenance considerations for a CNC machine when using it to cut pom pieces?

A: There is need for regular cleaning so as remove chips and other debris left behind during cutting process since accumulation of such materials can affect performance of machines used in pom processing. Furthermore one should ensure that cooling systems are functioning properly since failure may result into over heating of workpiece material thus causing damage.

Q: In relation to other plastics what is the environmental impact associated with cnc milling pom like?

A: Compared to many plastics cnc milling pom has relatively low environmental impacts mainly because it is durable, resistant towards chemical degradation besides being recyclable. Its extended lifespan reduces replacement rates thereby making it an eco-friendly option for various engineering applications.
