The Guangshu (GSK) and FANUC systems are both frequently used Computer Numerical Control (CNC) systems, but they have several differences in programming languages, code formats, coordinate systems, and operational aspects1. Key Differences: Programming Language and Code Format Both systems use G-code and M-code for programming, where G-code defines the tool's movement and cutting parameters, and M-code controls the machine's auxiliary functions1. However, FANUC's G-code and M-code formats are more concise compared to Guangshu1. Syntax Guangshu has a simpler syntax and is easier to learn. Its structure includes program segments, block segments, and sentence segments1. FANUC has a more complex syntax, including program segments, block segments, variable declarations, and control statements1.

A surface grinder is a precision manufacturing equipment that uses a rotating abrasive wheel to grind workpieces to achieve the required flatness. They are widely used in industrial fields such as automobile manufacturing, machinery and equipment manufacturing, and electronic equipment manufacturing for surface processing of various metal materials.Main Components: Bed: As the foundation of the grinder, it supports and positions other components. It is usually made of cast iron or steel plates to ensure rigidity and stability. Some beds use an integrated granite structure, which has the characteristics of high damping, low vibration, and good thermal stability, which can ensure the high rigidity and high stability of the grinder. Worktable: Used to place workpieces, it is usually made of cast iron or steel plate and the surface is finished to a high precision. It can be moved precisely to allow workpieces to be precisely machined on the grinder. According to the shape, the worktable can be divided into rectangular and circular types. Grinding Wheel: The main cutting tool of the grinder, it grinds the workpiece by rotating at high speed to achieve the required flatness. It can be replaced as needed to suit different processing requirements. The size of the grinding wheel and the abrasive particle size directly affect the surface quality, flatness, straightness, and dimensional accuracy of the processed workpiece. Hydraulic System: Used to drive various components of the grinder, the hydraulic pump converts electrical power into hydraulic power to drive the movement of the worktable, grinding wheel, etc. Compared with mechanical transmission, hydraulic transmission has the advantages of smooth transmission, overload protection, and stepless speed regulation within a large range. Cooling System: Used to cool the cutting area and prevent the workpiece and grinding wheel from overheating. The coolant can take away the heat from the cutting area and lubricate the grinding wheel, improving machining efficiency. Wet grinding allows adding water while grinding, so that the dust is washed away by the water and cannot fly around, solving the problem of excessive dust during processing and affecting the processing environment. Control System: Used to control the operation of the grinder. The operator can adjust the rotation speed, feed rate, and other parameters of the grinding wheel through the control system to meet different processing requirements. Sliding Seat: A platform capable of making the workpiece move horizontally back and forth. It is the power for grinding the workpiece, and the smoothness of its movement directly affects the quality of the processed surface, flatness, straightness, and dimensional control accuracy. The sliding seat has two movement modes: manual and motorized. Sliding Seat Baffle: Connected to the sliding seat, it is used to block the workpiece when the workpiece flies out due to excessive grinding force exceeding the magnetic attraction of the magnetic chuck, so as not to injure people or damage other surrounding equipment. Column: A support used to adjust the height of the grinding wheel up and down, and also the track for the grinding wheel holder to move.

When designing the control circuit system for a CNC lathe manufacturer’s press, it is essential to base the design on functional requirements while fully considering factors such as user safety, ease of maintenance, and good production performance. The key focus is to ensure the reliable and safe stopping of the press, and to develop a plan for the control circuit system. Below is an introduction to the control circuit flow by the CNC lathe manufacturer:The plan for selecting the control circuit system must ensure that once the press receives a stop command, it will quickly cut off all power, swiftly and correctly disengage the clutch and brake, and ensure that all components are unable to start a stroke in case of a fault. If any component of the control circuit fails during the downward stroke of the ram, the punch will stop working immediately, preventing the ram from continuing to descend. While meeting the punching function and ensuring safety, the control circuit system should be simplified as much as possible to minimize both the quantity and variety of components used. Below are some typical control circuits that illustrate the requirements for functionality and safety in CNC lathe control circuits.    The control circuit for the initial punching operation is relatively simple. This circuit only meets the four operational methods that a press should generally satisfy: single stroke, automatic stroke, continuous stroke, and jog stroke, without considering more thoughtful issues.Based on the operational characteristics of a single stroke and the requirements for various pressure processing, designers seek an ideal safety control system, which is not only an important goal but also a good opportunity to showcase their technical skills.To this end, many designers have put considerable effort into the design of the control system and have gradually improved the control circuit system based on continuous summarization of production and practical experience.

Dry Components in an Oven: Place the damp components and parts in a drying oven (preferably one with temperature control) to ensure they are thoroughly dried. Reassemble Components: Once dried, reassemble the disassembled components back into the machine. Test Each Component: After reassembly, power on each component individually to check for functionality and ensure they are working properly. Professional Reinstallation: Have qualified personnel reinstall the tested components back into the CNC lathe. Startup and Calibration

  Tool Position Point: This is the reference point for the tool, also known as the focus point during tool setting, which is typically a specific point on the tool itself. Starting Point: The starting point is where the tool begins its movement relative to the workpiece, marking the initial position of the tool at the start of the machining program. It often also serves as the endpoint of the program. Tool Setting Point and Tool Setting: The tool setting point is used to determine the relative position between the tool and the workpiece. It establishes the relationship between the workpiece coordinate system and the machine coordinate system. Tool setting involves placing the tool position point at the tool setting point to establish the workpiece coordinate system. Tool Setting Reference Point: This is a benchmark used to determine the position of the tool setting point. It can be a point, line, or surface located on the workpiece, fixture, or machine. Tool Setting Reference Point: This point represents the position of the tool holder, tool post, or tool turret within the machine coordinate system, also known as the tool holder center or tool reference point. Z-axis tool setter     Install the Tool: Mount the tool on the spindle and attach the Z-axis tool setter to the surface of the workpiece or fixture that has already been clamped.

Preparations needed for a CNC lathe before operation: Preheating: Before starting the CNC lathe, it is necessary to preheat the machine and carefully check if the lubrication system is working properly. If the CNC lathe has not been used for a long time, manual lubrication can be applied to each part first. Tooling Inspection: The tools used should be compatible with the specifications allowed by the CNC lathe. Severely damaged tools should be replaced promptly. When adjusting tools, make sure none are left inside the CNC lathe. Workpiece and Tool Preparation: Check if the holes of large-size shaft parts are suitable. If the holes are too small, it may cause danger during operation. After installing the cutting tools, perform a trial cut. Connection and Clamping Inspection: Check the connection between the chuck and the spindle, as well as the state of the workpiece clamping. Before starting the CNC lathe, ensure that the protective door is closed.

The guide rails of a CNC lathe intersect with the horizontal plane, forming inclined planes at various angles (such as 30°, 45°, 60°, and 75°). The bed of the lathe is designed in the shape of a right triangle. Clearly, with the same guide rail width, the X-axis slide of the inclined bed is longer than that of the flat bed. This design allows for more tool positions to be arranged, thereby increasing machining efficiency. Additionally, the cross-sectional area of the inclined bed is typically larger than that of a flat bed of the same specifications, enhancing the machine's resistance to bending and twisting, thus improving overall stability and precision. Control of Thermal Deformation in the Spindle Box   Heat Reduction: By separating the internal heat sources (such as motors and hydraulic systems) from the main machine, the temperature rise of the spindle is minimized. Additionally, using precision rolling bearings and oil mist lubrication helps to reduce friction heat generation. Temperature Control: Effective cooling measures, such as forced cooling and liquid cooling, are implemented to control the machine's temperature and mitigate the impact of heat sources on machining precision. Thermal Displacement Compensation: Mathematical models are established to compensate for the effects of thermal deformation in real time, enhancing machining precision. Preparations Before the Trial Operation of the Lathe   Cleaning the Machine: Use a cotton cloth or silk cloth soaked in a cleaning agent to remove rust-proof oil or paint from the guide rails and machining surfaces, as well as dust from the machine's exterior. Lubrication Check: Carefully check whether oil has been added to each part as required, ensure that there is enough coolant in the cooling tank, and verify the oil level in the hydraulic station and automatic lubrication device.
