Why Machining Quotes Vary Between Suppliers: A Case Study

Leave a Comment / 3D carving part, Benefits of CNC Milling, CNC machining parameters, CNC milling machines /

When sourcing custom machined parts, it’s common to encounter dramatically different quotations from various suppliers — sometimes varying by more than 300%. To the untrained eye, this may seem arbitrary or even suspicious. But in reality, these price gaps often reflect fundamental differences in how each supplier interprets the drawing, plans the process, and accounts […]

In the fast-paced world of product development, delays can be costly. One common—but often overlooked—cause of delay is the lack of early communication between the customer and the supplier about how a custom part functions and interacts with its mating components. As an experienced metal parts supplier, we’ve seen it time and again: a part

Technical Guide to Aluminum Surface Treatments

Leave a Comment / 3D carving part, Manufacturing Machine Parts, OEM Metal Part Services, OEM metal parts /

Understanding corrosion protection, appearance, and cost-performance trade-offs Aluminum is widely favored in engineering due to its excellent strength-to-weight ratio and natural oxidation resistance. However, most industrial applications demand additional surface treatments to enhance corrosion resistance, improve appearance, enable conductivity, or support downstream processing like painting or bonding. Below is a summary of the most common

CNC Machining Effects on Stress and Dimensional Stability

Leave a Comment / CNC machining parameters, CNC Machining Processes /

Understanding how CNC machining processes affect internal stress and dimensional stability is essential for producing reliable and accurate parts. Each stage of machining — from rough cutting to finishing — can influence not only the tensile stress within the material but also cause stress release that results in part deformation and unstable dimensions. This section

When Should Threaded Holes Be Milled Instead of Tapped?

Leave a Comment / CNC machining parameters, CNC Machining Processes /

In CNC machining, both tapping and thread milling are common methods to create internal threads. However, under certain high-precision conditions, tapping may no longer be suitable. One key situation is when a threaded hole must meet both tight diameter tolerance (below ±0.005 mm) and geometric tolerances such as true position or coaxiality.  Why Is Tapping

Dimensional Changes from Stress Release in CNC Machining

Leave a Comment / CNC machining parameters, CNC Machining Processes, CNC milling machines, CNC Precision Machines /

In CNC machining, we often encounter dimensional changes caused by stress release in materials. When a material undergoes milling, drilling, or cutting, internal stress redistributes, potentially leading to shrinkage or expansion of the workpiece, resulting in dimensional instability. This not only affects machining precision but also impacts assembly compatibility. To ensure product quality, we implement

CNC Machining Impact on Workholding & Stability

Leave a Comment / CNC machining parameters /

In CNC machining, the stability of workholding fixtures plays a crucial role in ensuring machining accuracy. However, environmental factors such as temperature fluctuations, spindle load variations, cutting forces, and vibrations can cause subtle shifts in fixture positioning, leading to inconsistencies in workpiece alignment and dimensional instability. Recognizing the critical importance of precision in high-quality components,
