  • After rough machining is completed, finish machining is performed. Reduce the cutting depth and feed speed, and increase the cutting speed to obtain higher machining accuracy and surface quality.
  • Pay attention to controlling the temperature during processing to avoid workpiece deformation or tool wear due to excessive temperature. A cooling system can be used to cool the tool and workpiece and reduce the processing temperature.

7.Quality check

  • After the processing is completed, the trapezoidal screw is inspected for quality. Mainly check whether the dimensional accuracy, surface roughness, tooth shape accuracy, etc. meet the design requirements. Measuring equipment such as measuring tools and profilometers can be used for measurement.
  • For parts that do not meet the requirements, appropriate trimming or reprocessing will be carried out until the quality requirements are met.

8.Surface treatment

According to the use requirements of the trapezoidal screw, surface treatment is carried out, such as quenching, carburizing, chromium plating, etc., to improve the hardness, wear resistance and corrosion resistance of the screw.

9.Cleaning and packaging

  • Clean the processed trapezoidal screw to remove surface oil, chips and other impurities. Cleaning agents and compressed air can be used.
  • Pack the screw and take appropriate protective measures to prevent damage during transportation and storage.

In short, using a Whirling machine to process trapezoidal screws requires sufficient preparation, reasonable setting of processing parameters, strict control of quality during processing, and appropriate follow-up processing to ensure that the processed trapezoidal screws meet design requirements and usage standards.

Strong adaptability

Whirling can be adapted to the processing of trapezoidal screws of different materials, different diameters, and different pitches. You only need to replace the corresponding cutting tools and adjust the processing parameters to process trapezoidal screws of different specifications.

High degree of automation

Modern Whirling equipment usually has a high degree of automation and can achieve automated processing. Through programming control, automatic control of the processing process can be realized, improving production efficiency and product quality.

How To Ensure The Processing Accuracy Of Trapezoidal Screw?

To ensure the processing accuracy of trapezoidal screws, you can start from the following aspects:

1.Selection and maintenance of processing equipment

Choose high-precision machine tools

  • Choose processing machine tools with high rigidity and high precision, such as CNC Whirling machines, Whirling machines, etc. These machine tools can provide a stable processing platform and ensure precision control during the processing process. For example, high-precision ball screws and linear guides are used to ensure the movement accuracy of the machine tool.
  • Pay attention to the spindle accuracy of the machine tool. The rotation accuracy of the spindle directly affects the machining accuracy of the screw. Choose a spindle with high speed and low vibration to improve processing quality.

Regular maintenance

  • Carry out regular maintenance on processing equipment to ensure that the performance of machine tools is in good condition. Including cleaning machine tools, checking lubrication systems, adjusting tool clamping devices, etc.
  • Regularly conduct accuracy testing and calibration of machine tools, such as using laser interferometers and other equipment to detect the positioning accuracy and repeatable positioning accuracy of machine tools, and make timely adjustments if problems are found.

2.Selection and use of tools

Suitable tool materials

  • Select the appropriate tool material according to the material of the trapezoidal screw. For materials with higher hardness, you can choose carbide cutting tools; for ordinary materials, you can choose high-speed steel cutting tools. The material of the tool should have good wear resistance and cutting performance to ensure processing accuracy.
  • For example, when processing stainless steel trapezoidal screws, cobalt-containing high-speed steel tools or carbide tools can be used to improve the durability and cutting efficiency of the tools.

Optimization of tool geometry parameters

  • Reasonably select the geometric parameters of the tool, such as the rake angle, relief angle, edge inclination angle, etc. of the tool. These parameters directly affect cutting force, cutting heat and tool wear, thereby affecting machining accuracy.
  • For the processing of trapezoidal screws, larger front and rear angles are generally used to reduce cutting force and cutting heat and improve processing accuracy. At the same time, select an appropriate edge inclination angle to ensure the stability of the cutting process.

Installation and adjustment of cutting tools

  • Make sure the cutting tool is securely mounted to avoid loosening or vibration during machining. When using the tool clamping device, ensure uniform clamping force to prevent tool deformation.
  • Precisely adjust the tool so that it is perpendicular to the axis of the workpiece and ensure that the contact point between the cutting edge of the tool and the workpiece is in the correct position. You can use tools such as tool setters to adjust and measure tools.

3.Control of processing technology

Reasonable processing sequence

  • Develop a reasonable machining sequence, perform rough machining first, remove most of the allowance, and then perform semi-finishing and finishing. This can avoid deformation of the workpiece due to stress concentration during the machining process and affect the machining accuracy.
  • During the processing process, attention should be paid to the reasonable arrangement of heat treatment and aging treatment between processes to eliminate the internal stress of the workpiece and improve the stability of the processing accuracy

Optimization of cutting parameters:

  • According to the material of the trapezoidal screw, the performance of the cutting tool and the machine tool, appropriate cutting parameters are selected, including cutting speed, feed speed and cutting depth. Optimizing cutting parameters can improve processing efficiency while ensuring processing accuracy.
  • For example, in the finishing stage, smaller cutting depth and feed speed should be used to reduce cutting force and cutting heat and improve processing accuracy. At the same time, the cutting speed should be increased appropriately to improve the surface quality.

Cooling and lubrication

  • During the machining process, effective cooling and lubrication measures can lower the cutting temperature, reduce tool wear, and improve machining accuracy. Coolant, cutting oil, etc. can be used for cooling and lubrication.
  • Ensure the normal operation of the cooling and lubrication system, and replace coolant and cutting oil in a timely manner to ensure the stability of the machining process.

4.Measurement and Inspection

Choose the right measuring tool

  • According to the accuracy requirements of the trapezoidal screw, select appropriate measuring tools, such as micrometers, calipers, thread gauges, etc. These tools should have sufficient precision and reliability to ensure the accuracy of measurement results.
  • For high-precision trapezoidal screws, precision measuring equipment such as three-dimensional coordinate measuring machines can be used to measure to ensure that the processing accuracy meets the requirements.

Strict inspection system

  • Establish a strict inspection system to inspect all aspects of the processing process, including blank inspection, inter-process inspection and finished product inspection. Discover problems promptly and make adjustments to avoid the production of substandard products.
  • During the inspection process, attention should be paid to the correctness and consistency of the measurement methods to ensure the reliability of the measurement results. At the same time, inspection data must be recorded and analyzed in order to improve and optimize the processing process.

In short, to ensure the processing accuracy of trapezoidal screws, comprehensive control is required from multiple aspects such as processing equipment, cutting tools, processing technology, and measurement and inspection. Through reasonable selection and use of equipment and tools, optimization of processing technology, and strict measurement and inspection, the processing accuracy of trapezoidal screws can be effectively improved to meet the needs of various applications.
