What is the difference between a 4-axis CNC milling machine and a router or engraving machine?
The 4-axis CNC milling machine’s fourth rotary axis allows it to work on complex 3D parts, enabling deeper cuts and multi-sided machining in one setup. In contrast, routers and engraving machines are mainly used for soft materials. They are mainly used for surface carving and shallow engraving rather than heavy-duty milling or cutting of metals.
Can a four-axis CNC machine perform both drilling and milling simultaneously?
Yes. Most four-axis CNC milling machines combine milling and drilling capabilities. The rotary axis allows the tool to access various angles, allowing drilling on different surfaces without repositioning the workpiece. This helps you machine complex parts more efficiently.
Can the 4-axis CNC milling machine engrave detailed patterns?
Yes, it can. Thanks to the additional rotary axis, this machine can precisely engrave complex 3D surfaces and wrap intricate designs around cylindrical parts. These tasks are difficult or even impossible to finish with standard 3-axis machines. Our 4-axis milling machines have possibilities for detailed and curved engraving.
What’s the price of 4 4-axis CNC milling machine?
The price of a four-axis CNC milling machine depends on its base size, core components, and optional functions. The factors include spindle specification, tool system, table dimensions, X/Y/Z travel, accuracy class, and any automation extras. Provide your main requirements and part drawings, and we will reply with a tailored quotation, detailed spec sheet, and available OEM options.
What’s the difference between a drilling and milling machine and a 4-axis CNC milling machine?
A drilling and milling machine typically refers to equipment that performs both drilling (creating holes) and milling (removing material to shape parts) functions, often on a simpler, manual, or basic CNC platform. It usually operates with three axes (X, Y, and Z) and requires repositioning the workpiece to access different angles.
In contrast, a 4-axis CNC milling machine adds a rotary axis (often called the A-axis), allowing the workpiece to rotate during machining. This enables multi-surface and complex contour machining in a single setup without manual repositioning. As a result, 4-axis CNC machines are capable of producing more complex parts than standard drilling and milling machines.
If you’re new to CNC machines, it’s natural to ask: what’s the difference between a 3-axis and a 4-axis milling machine, and when does that extra axis make a real difference? Let’s break it down.
A 3-axis CNC milling machine moves the tool along three directions—X (left/right), Y (forward/back), and Z (up/down). It’s great for machining flat surfaces and basic shapes. But when a part needs work on several sides, you have to stop the machine, reposition the part manually, and restart the process. This adds time, and each setup increases the chance of small errors.
A 4-axis machine adds a rotating axis (typically the A-axis), allowing the workpiece to turn during machining. This means the tool can reach multiple faces in one setup, with no need to stop and re-clamp.
For shops handling batch production, multi-face machining, or high-precision parts, a 4-axis CNC milling machine can make a big difference. It helps you handle more jobs with consistent quality, whether you’re in automotive, industrial, or mold-making.
