Guide Rail Precision: Swiss-type lathes typically employ high-precision linear guide rails to ensure the motion accuracy of the spindle and cutting tools. Linear guide rails provide stable linear motion, reducing vibration and error during the machining process.
Guide Rail Maintenance: Regularly inspect the wear condition of the guide rails, ensuring that the rail surfaces are clean and free of dust and debris. Replace worn guide rail components in a timely manner to maintain machining accuracy.
Linear Motor Drive
High Speed and Precision: Linear motor drives can achieve high-speed, high-precision linear motion, significantly enhancing machining efficiency and accuracy.
Dynamic Response: Linear motors have rapid dynamic response capabilities, enabling precise control of tool feed speed and position, and adapting to complex machining paths.
Coordination Between Spindle and Linear Motion
Spindle Movement: The spindle in a Swiss-type lathe not only rotates but also moves linearly along the Z-axis with high precision. This design reduces the number of workpiece setups, minimizing the loss of accuracy due to setup errors.
Tool Fixing: The cutting tool remains fixed during the machining process, with the Z-axis movement and C-axis rotation of the spindle completing the machining. This method is particularly suitable for high-precision, slender shaft parts.
Control System and Linear Positioning
CNC System: Advanced CNC systems can support multi-axis联动control, high-speed cutting, and high-precision positioning. Through precise interpolation and real-time feedback control, the CNC system ensures the accuracy of linear positioning.
Software Support: CNC programming software can convert machining drawings into digital control programs, including tool paths, feed rates, tool speeds, and machining depths.
Design of Positioning Devices
Precision Adjustment: Positioning devices can precisely adjust the lateral position of the workpiece for flexible machining. The combination of electric linear actuators and limit plates can hold the workpiece and make adjustments, increasing the range of adjustment.
Adaptability: Positioning devices can be disassembled and replaced according to the arc of the workpiece's outer surface, adapting to workpieces of different sizes and shapes.
Linear Positioning During Machining
Reducing Setup Errors: Swiss-type lathes reduce the number of workpiece setups by completing machining through spindle movement and rotation, thereby minimizing the loss of accuracy due to setup errors.
Continuous Machining: Swiss-type lathes can complete multiple machining processes in a single setup, reducing the number of workpiece setups and adjustment times, greatly improving machining efficiency.
By implementing the above key points, Swiss-type lathes can achieve high-precision, high-efficiency linear positioning, meeting the machining demands of high-precision fields such as medical devices.
