Basic knowledge of 2-axis CNC machine

Unlocking manufacturing efficiency: fundamentals of 2-axis CNC machining

In the dynamic world of modern manufacturing, CNC (Computer Numerical Control) machining is a cornerstone technology that converts blocks of raw materials into precise components with incredible speed and accuracy. Although multi-axis machines such as 5-axis become most of the focus of complex geometries, basic technology – 2-axis CNC machine – Still an important main force in countless workshops and factories. Understanding its operation, functionality and limitations is essential for anyone involved in part design or manufacturing. At Greatlight, we recognize the lasting value and specific advantages of a reliable 2-axis system when we exhibit highly complex metal parts in advanced 5-axis machining.

What exactly is a 2-axis CNC machine?

At its core, a 2-axis CNC machine precisely controls the movement of the cutting tool along two linear paths. These are almost always:

1. X-axis: Usually horizontal movement left and right.
2. Y-axis: Usually, it is forward and backward horizontal movement (perpendicular to the X-axis).

At the same time, the workpiece is usually fixed to a machine tool or a table. The cutting tool rotates at high speed (driven by the spindle), and the coordinated XY motion guidance tool determined by programming instructions (G code) removes the material and forms the parts. No program Movement of the workpiece itself or tool (vertical movement) (z-axis) relative to the workpiece during the cutting process; Z-axis movement is usually manual, or used to position simple tools to different depths before the XY plane begins cutting. Some common examples include:

• CNC Mills: Mainly used in milling operations, where a rotating cylindrical cutter removes material.
• CNC router: Usually larger, used to cut wood, plastic, foam and soft metal, common in symbol making, woodworking and prototyping.
• CNC plasma cutter: Follow the 2D path and use plasma torches to cut out conductive materials such as steel.
• CNC laser cutting machine: Cut or engrave the material in 2D using a focused laser beam.

How does it work? This process simplifies

1. Design and Programming: Created a 2D CAD (Computer Aided Design) diagram of the required parts. The design is then converted into machine-readable G-code using CAM (Computer Aided Manufacturing) software. The G code specifies the exact tool path, spindle speed, feed rate and cutting depth.
2. set up: Clip the raw materials (paper, board or block) firmly on the machine’s workbench. Suitable cutting tools (e.g., end mills, drills, plasma torches, laser heads) are loaded into the spindle or bracket of the machine. The tool length and diameter offset are calibrated.
3. implement: The operator starts the program. The machine’s controller interprets the G code and accurately drives the motor that controls the X and Y axes. The rotating tool moves along the programmed path on or through the fixed workpiece, removing material only in the horizontal plane at the preset depth. The spindle speed and tool feed rate are maintained according to the program settings.
4. Finish: Once the program cycle is completed, the machine will stop. The finished parts are not clamped and any necessary post-machining is performed (e.g., Deburring).

Core components of 2-axis CNC machine

• Frame/Bed: The rigid base and structure supporting all components provide stability and vibration damping.
• Worksheet: The surface of the workpiece securely secured (clipping or holding with a sub/clutch).
• Linear Guide/Rail: Precision tracks slide along the moving axis.
• Ball screws/lead screws: The rotary screw driven by the motor converts the rotational motion into a highly accurate linear motion of the shaft.
• Stepper/Servo Motor: Power is provided to drive ball/lead screws to move the shaft to the precise position directed by the controller.
• Spindle: The motor-driven assembly rotates the cutting tool at high speed. Spindle power (HP/kW) and maximum rpm are the key specifications.
• Tool holder/collet: Secure the cutting tool (e.g., Collet, drill bit) inside the spindle.
• CNC controller: this "brain" machine. It reads the G code, processes the instructions and sends the signal to the motor and spindle drivers. Includes a user interface.
• Coolant system (optional but common): Flushing debris (SWARF) and cooling the tool/workpiece to prevent overheating and tool wear is especially important for metalworking.
• Axis/Servo Driver: Amplify the signal from the controller to power the motor.

Advantages of 2-axis CNC machining:

• Cost-effective: Machine costs are significantly reduced, while 3, 4-axis or 5-axis equivalents. Simple programming and setup means that 2D jobs are less costly to operate.
• Simplicity and ease of use: Easier to program, set up and operate than taller machines. Training requirements are usually low.
• Speed ​​and efficiency: For dedicated 2D analysis and cutting applications such as plasma/laser cutting board metal or routing wood panels, 2-axis machines are usually faster and more efficient.
• Accuracy and repeatability: High-quality accuracy (±0.001 for 2D functions" or better). Perfect for mass production of the same 2D parts.
• Reliability and robustness: Simpler mechanics translate into components that are prone to failure, resulting in reliable and reliable machines.

limit:

• Geometric constraints: Intrinsically limited to 2.5D processing. There is no way to create complex 3D outlines, undercuts or the ability to simultaneously move tools/workpieces on multiple axes.
• Manual intervention: Tool changes that require manual repositioning of the workpiece or operator to operate at different sides or intricate angles. Slowed the production of multi-faceted work.
• Setting complexity of multi-faceted parts: The machining functions on multiple faces of a workpiece often require complex fixation and multiple settings, increasing the likelihood of time and error.

2-axis vs. Multi-axis: Select the right tool

• When selecting 2 axes:

  • Your parts are mainly 2D or simple 2.5D (pockets, holes, profile cut on one side).
  • The speed and cost efficiency of fixed parts are crucial.
  • Production is high, and all features are accessible from one side.
  • The material being processed is effectively processed by a 2D cutting method (eg, by laser/plasma plate metal).

• When considering multi-axis (3+axis, such as 5-axis):

  • Your parts have complex 3D profiles, sculpted surfaces, or features of multiple faces that require composite angles.
  • A complex setup is required to avoid multiple fixture/machine settings, thereby improving accuracy and reducing production time.
  • Precise machining is required at odd angles (including undercut).
  • You need to reduce the lead time for complex components by minimizing setup changes.
  • You need high-precision, space-complex parts commonly found in the aerospace, medical or advanced automotive fields.

Frequently Asked Questions about 2-axis CNC Machines (FAQs)

1. Q: What’s there "2.5D processing" Average related to 2 axes?
   one: "2.5d" Refers to the tool moving in both X and Y axes to create a path, while the Z axis (depth) moves only at a specific point or is set to a fixed depth between Main XY movement. It can create step profiles, pockets and engraving functions at different depths, but not real, ever-changing 3D surfaces. The true 2-axis cut only at one z-depth for each operation.

2. Q: Can a 2-axis CNC machine make holes?
   Answer: Absolute. Drilling is a common and effective operation of 2-axis machines. The spindle (with drill bit) position is rapidly positioned at the hole position (X and Y motion), lowered to the programmed depth on the Z axis, drilled and retracted. Multiple holes can be drilled sequentially according to programming.

3. Q: How to bring the design into a 2-axis machine?
   one: You start with a 2D CAD graph (in formats like DWG, DXF, or SVG). Then import this diagram into the CAM software. The CAM software allows you to define tool paths based on geometry, select tools, set speed/feed and depth. Finally, the CAM software generates a computer-specific G-code program that is loaded onto the machine’s controller (usually via USB, network, or direct transmission).

4. Q: Are 2-axis machines only suitable for soft materials such as wood?
   Year. Although CNC routers typically target wood, plastics, and composites, a dedicated 2-axis CNC mill is designed to handle metals including aluminum, brass, and steel. CNC plasma and laser cutters are powerful 2-axis systems specially made for efficient cutting of sheet metal. Material capability depends to a large extent on the construction of the machine, the power supply (spindle or torch/laser source) and the stiffness.

5. Q: When do I need more than 2 axes (e.g. 3 axes or even 5 axes of Greatlight)?
   one: You need the following multi-axis (3+axis):

   • Parts that need to be machined on multiple sides without manual repositioning.
   • Create complex 3D shapes (curves, profiles, organic surfaces, impellers, molds).
   • A composite angle or undercut function that is impossible from a single angle.
   • Significantly reduces the setup time of geometric complex parts.
