3-Axis CNC Machining Service

Requirements for Machining Equipment

1.3-Axis Simultaneous Motion Control System

The machine must support simultaneous interpolation and movement along the X, Y, Z linear axes, enabling stable machining of flat surfaces, inclined planes, grooves, holes, steps, and simple curved surfaces. It should be equipped with a reliable numerical control system for precise path control.

2.High-Rigidity Mechanical Structure

The machine bed, column, and worktable require high structural rigidity to minimize vibration, deformation, and deflection during cutting. High-precision linear guides, ball screws, and servo drive systems ensure stable motion and long-term dimensional accuracy.

3.High-Performance Spindle

The spindle must provide a wide speed range, strong cutting torque, and good dynamic balance. It should maintain stability during high-speed and heavy-duty cutting to ensure surface finish and tool life.

4.High Positioning and Repeat Positioning Accuracy

The machine must meet strict industrial standards for positioning accuracy and repeatability to guarantee consistency in single-piece and mass production.

5.Tool and Cooling System

Equipped with a tool magazine or automatic tool changer (ATC) for multi-process machining. An efficient coolant system is required for heat dissipation, chip removal, lubrication, and extending tool service life.

6.Reliable Workholding System

Compatible with vises, fixtures, vacuum chucks, and hydraulic clamping devices to securely hold workpieces of various materials and sizes.

Requirements for Skilled Workers / Operators

1.CNC Programming & CAD/CAM Skills

Proficiency in reading 2D engineering drawings and 3D models. Ability to generate toolpaths using CAD/CAM software (such as Mastercam, UG/NX, Powermill, SolidCAM) and edit basic G-code and M-code programs.

2.Machine Setup & Operation

Capable of independently installing and clamping workpieces, setting work coordinates, tool setting, zero-point calibration, and parameter adjustment. Familiar with operation panels and daily machine debugging.

3.Technical Drawing Interpretation

Accurate understanding of dimensional tolerances, geometric tolerances (GD&T), surface roughness requirements, and machining benchmarks.

4.Machining Process Knowledge

Understanding of cutting characteristics of various materials (aluminum, steel, stainless steel, copper, plastics, composites). Ability to select appropriate cutting tools, feed rates, spindle speeds, and machining strategies to avoid tool breakage, workpiece deformation, or overheating.

5.Quality Inspection & Control

Skilled in using measuring tools such as calipers, micrometers, height gauges, dial indicators, and projectors to perform in-process inspection and final quality verification. Able to adjust parameters to correct dimensional deviations.

6.Safety & Maintenance Awareness

Strictly abide by safety operation procedures. Capable of basic machine maintenance, chip cleaning, daily inspection, and simple troubleshooting.
