At Yonglihao Machinery, we know how important precision is in CNC machining. POM, a common engineering plastic, has its own set of challenges. It’s known for its strong mechanical properties and tight tolerances, but it can spring back after machining.
This makes getting precise dimensions tricky. POM also tends to warp, so we often use fixtures to keep it in place. Keeping the temperature right is key to avoid melting or deforming the material during machining. Plus, we need to make sure chips are removed properly to prevent clogging and tool wear.
To get the best results, we adjust cutting parameters like speed, feed rate, and depth of cut. This helps us work faster without damaging the material. Let’s look at some specific challenges in machining POM.
Deformation from Cutting Heat
Deformation from cutting heat is a big problem when working with POM. This plastic doesn’t conduct heat well and can resist high temperatures. This can cause it to deform if the tool or cutting angles aren’t right.
We manage heat to keep dimensions accurate. The wrong spindle speed can make the material expand or contract, leading to warpage. At Yonglihao Machinery, we use coolants and adjust speeds to minimize deformation. This careful approach improves the quality and precision of our POM parts.
Managing Internal Stress
Internal stress is another challenge in machining POM. The material can develop internal tension that might cause cracking. To tackle this, we consider the material’s purity and use special POM materials.
We design parts to reduce internal stress through smart machining paths and feed speeds. This ensures we remove material efficiently while keeping the part strong. Before full machining, we often do trial runs to check for internal stress. Managing internal stress is crucial for parts that need to stay stable and functional. At Yonglihao Machinery, we aim to deliver parts that meet the highest standards.
Ensuring Dimensional Accuracy
Getting precise dimensions is key when machining POM for high-precision components. POM’s low thermal expansion helps keep dimensions stable over temperature changes. Its low moisture absorption also helps maintain size consistency, even in changing environments.
We can achieve tight tolerances, as precise as ±0.025mm, by managing temperature and refining our machining. POM’s stiffness also helps it hold up under load, making it great for precision machining. At Yonglihao Machinery, we focus on these factors to deliver components that perform well in various industrial settings.
