Overcoming the Challenges of MIM & CNC Machining for Precision Internal Corners
Introduction: The Precision Roadblock in Your MIM Project At Samshion, we often encounter a familiar challenge in metal component manufacturing: the gap between the theoretical capabilities of Metal Injection Molding (MIM) and the practical limits of post-process CNC machining, especially for tight internal radius. As shown in this project, even when MIM delivers a near-net-shape […]
An In-Depth Overview of Reamers: Classification, Applications, and Design Principles
Over years of supporting global customers in CNC machining and precision tooling, the Samshion team has accumulated extensive hands-on experience with reamers, hole-finishing processes, and tolerance control. In actual production—whether dealing with small-batch prototypes or high-volume precision components—we consistently observe that the correct choice of reamer type, reaming allowance, cutting parameters, and tool material directly […]

Wire EDM Troubleshooting Guide: Entry Marks, Corners and Deformation
Wire EDM defects rarely come from one machine setting. This guide explains how to diagnose entry marks, corner errors, residual-stress movement, thick-section variation, slug control, taper and surface problems without relying on universal offsets or unsupported accuracy promises.
CNC Machining vs. 3D Printing: The Ultimate Selection Guide for Engineers
At Samshion Rapid, our engineers are asked one question daily: “For this part, should I use CNC machining or 3D printing?” The answer is never black and white. It hinges on a complex equation balancing end-use, material properties, cost, and timeline. This guide cuts through the hype to give you the practical insights you need to make […]
End Milling Guide: Techniques, Tools & Tips
Samshion Rapid’s production team takes pride in using end milling not just as another machining step—but as a core capability tailored to handle complex geometries and demanding surface finishes using our Haas CNC centers. When machining materials like stainless steel, aerospace alloys, or engineering-grade plastics, we precisely control every cut—only removing material where needed. This […]
CNC Machining vs Additive Manufacturing: Which Process Should You Choose?
Compare CNC machining and additive manufacturing by geometry, materials, tolerance, surface finish, cost, lead time and production volume. Learn when to choose CNC, AM or a hybrid process.
