Technical Requirements and Specifications for CNC Lathes

During the installation and commissioning phase of CNC lathes, specific technical prerequisites and specifications must be met to ensure proper functioning and accuracy. These requirements are crucial for the successful setup and operation of the equipment.

Ambient Temperature and Humidity Control:

Maintaining a constant temperature of approximately 20 degrees Celsius is imperative to uphold the precision of the CNC lathe.
High temperatures, especially in summer, can elevate the risk of system failures and potential collisions. Therefore, a controlled environment is essential.
Adequate dehumidification measures should be implemented to prevent circuit short-circuits, ensuring the reliability of CNC lathe operations.
Vibration and Interference Avoidance:

CNC lathes should be positioned away from sources of vibration, such as forging equipment, to prevent disturbances during operation.
They should also be situated clear of electromagnetic field interference, electric welding machines, wire-cutting machine tools, and electric discharge machine tools.
Standardized Debugging Actions:

G00 Speed Selector Switch at F0:

When debugging the program, use the G00 speed selector switch at F0 to allow the tool to approach the workpiece at a controlled, slow speed.
This precautionary measure helps prevent potential strong collisions in case of tool offset errors.
Single-Stepping and Continuous Verification:

During program debugging, the CNC lathe must be operated in single-step mode.
After executing each block, operators must verify the correctness and rationality of the next block before proceeding.
Continuous Tool Coordinate Monitoring:

Operators must consistently monitor the changes in tool coordinates displayed on the screen, ensuring alignment with the programmed coordinates for movement.
Emergency Stop Preparedness:

While debugging, operators should position one finger on the cycle start button and the other on the cycle hold button, enabling rapid program cessation in emergencies.
Familiarity with the emergency button's location is essential for prompt response.
Machine Reference Point Setting:

During machine startup, it is imperative to set the machine reference point to align the coordinate system of the machine tool with the programmed system.
Proper tool length compensation must also be established to prevent collisions.
Utilization of Simulation Capabilities:

Take advantage of computer simulation capabilities to observe tool movements and identify potential collision risks during program debugging.
Graphical Simulation of Processing:

Many advanced CNC lathes feature graphic analog processing functions. Prior to automatic machining, perform a graphical simulation to verify the correctness of the tool path.
Strict Adherence to Operating Procedures:

Qualified Operation and Equipment Fixing:

Only qualified personnel should operate CNC equipment, and the equipment must be securely fixed in place.
Negotiation and Handover Protocols:

In cases where multiple individuals operate the equipment, effective communication and handover procedures must be followed. Equipment should not be replaced without the operator's consent.
Continuous Training and Responsibility Enhancement:

Operators should engage in ongoing training to enhance their technical proficiency and sense of responsibility.
Thorough Program Verification:

Before the initial processing, meticulously review the program and conduct a single-stage processing test to ensure accuracy.
Program and Data Checks:

After modifying programs and data, conduct rigorous checks and execute the first processing step in accordance with the modifications.
Safety-First Programming:

When programming, prioritize safety by selecting coordinate origins and tool change points that are foolproof and secure.
Optimized Cutting Parameters:

Select cutting parameters, including speed, cutting amount, and feed rate, to prevent overloading the equipment.
Workpiece Inspection and Clamping:

Inspect workpiece blanks for size and shape, and clamp them securely in a suitable position with properly adjusted clamping force.
Secure Tool Holder Fastening:

Ensure the tool holder is firmly and securely fastened in place.
Caution in Manual Movement:

Exercise care when manually moving the machine to avoid collisions.
Immediate Reporting of Abnormalities:

Notify maintenance personnel promptly in case of equipment abnormalities or collisions.
Professional Parameter Adjustment:

Adjust and modify machine parameters only with professional training and authorization.
Routine Equipment Maintenance:

Adhere to operating instructions, perform daily equipment maintenance, and complete equipment checklists as required.
By strictly adhering to these technical requirements and procedures, operational accidents with CNC lathes can be significantly reduced, ensuring safe and efficient production processes.
