The Underlying Logic of CNC Lathes: From Code to Motion
Release time：2026-03-18
1. Digitization of Processing Information (Code Generation)
- G-code defines the tool path;
- M-code controls auxiliary functions such as the spindle and cooling.
- The S/F/T code sets the spindle speed, feed rate, and tool parameters.
- The code is ultimately固化 into digital instructions that define the machining intent.
2. Program Input and Preprocessing
- Complete the coordinate system transformation;
- Optimize toolpaths and eliminate redundancy;
- Match device hardware capabilities to ensure secure operation.
3. Instruction Parsing and Motion Calculation
- Calculate the tool path based on G-code;
- Parse the M/S/F/T code and convert it into control signals;
- Determine the timing logic for each action.
4. Signal Conversion and Servo Drive
- The feed-axis servo drives the tool for precise movement;
- The spindle servo controls the workpiece rotational speed and is tightly coordinated with tool feed.
- This is the critical step in converting “digital instructions” into “mechanical actions.”
5. Closed-Loop Feedback and Error Compensation
- Immediately make fine adjustments for compensation upon detecting deviations;
- Correct for the effects of thermal deformation, tool wear, and other factors;
- Ensure that motion accuracy remains consistently stable.
6. Coordination of Action Execution and Timing
- Rough machining emphasizes efficiency;
- Fine machining emphasizes precision;
- Coolant supply, start-stop functions, and other auxiliary operations are precisely synchronized with the cutting operation.
- Ultimately achieving continuous, automated, high-precision machining.

Working Principle of Electric Welding Machines
The core function of an electric welding machine is to achieve a strong, durable bond between metals, with its operating principle fundamentally based on the conversion of electrical energy into thermal energy. By leveraging the coordinated operation of its internal core components, the machine converts mains electricity into the energy required for welding and ultimately fuses the metal through the heat generated by the electric arc, thereby completing the joint. The key components include step-down transformers in conventional models, inverters in high-frequency models, welding electrodes, and control circuits for stable process regulation. These components work in a division of labor to ensure that the welding process proceeds in an orderly and controlled manner.

What is nondestructive testing? What are the various NDT methods?
Nondestructive testing (NDT) refers to a quality-control technique that, without compromising the structural integrity, service performance, or internal microstructure of the test object, employs physical or chemical methods to perform qualitative, locational, and quantitative inspections for surface and subsurface defects—such as cracks, porosity, slag inclusions, lack of penetration, and looseness—in materials, components, and welded structures.

Core Principles and Procedures of Fire-Resistance Testing
This is a standardized, controlled test procedure conducted in a laboratory furnace, following nationally or internationally harmonized time–temperature exposure curves (such as GB/T 9978 and ISO 834), to subject building components, fire-protection materials, structural elements, fire-stopping assemblies, equipment enclosures, and similar items to simulated real-fire exposure conditions. Under specified loading, the test continuously monitors three critical performance indicators—load-carrying capacity, structural integrity, and thermal insulation—and defines the fire-resistance rating as the duration from the onset of fire exposure until the first failure of any one of these indicators, thereby providing a standardized, repeatable, and quantifiable method for scientifically assessing the fire-safety performance of materials and components.
