Manhart How to ensure the machining accuracy and stability of the torsion axis CNC bending machine?

In order to ensure the machining accuracy and stability of the torsion axis CNC bending machine, the following measures can be referred to, which will be elaborated in combination with relevant numbers and information in the reference article:
1、 Technical design and equipment selection
1. * * Rigid Design * *: Choose a body and workbench made of high-strength steel, and ensure the rigidity of the entire machine through reasonable layout and stable connection methods. Rigid design can effectively avoid vibration and deformation of the body and worktable during the processing, ensuring the stability and accuracy of the bending machine during use.
2. * * Precision guide rail and transmission system * *: Adopting high-precision linear guide rail and precise mechanical transmission methods such as gears and transmission belts. For example, using high-precision linear guides can reduce the frictional resistance of sliders and improve the accuracy of mechanical transmission.
3. * * CNC system * *: Priority should be given to bending machines equipped with advanced CNC systems, and precision machining can be achieved through precise control of machining parameters. The use of CNC systems can greatly improve the machining accuracy and repeatability of bending machines.
2、 Operational process optimization
1. * * Material preparation * *: Prior to bending, sufficient preparation work should be carried out on the metal sheet, including cutting, trimming, etc. Reasonable material preparation can reduce machining errors and improve machining accuracy.
2. * * Clamping fixation * *: Clamp and fix the metal sheet to be processed on the workbench to ensure its position and angle stability. The rationality of clamping and fixing will have a significant impact on the bending accuracy.
3. * * Parameter adjustment * *: Reasonably adjust the processing parameters of the bending machine, such as pressure, angle, speed, etc., according to the different processing requirements and workpiece materials. Accurate parameter adjustment can improve machining accuracy.
4. * * Processing monitoring * *: During the processing, operators should closely monitor the operating status and processing quality of the equipment, and make timely adjustments as needed.
3、 Process parameter adjustment
1. * * Bending radius * *: When performing free bending, pay attention to the relationship between the bending radius and the size of the V-groove opening, as well as the ratio between the bending radius and the material thickness. For example, the bending radius is generally 0.156 times the size of the V-groove opening, while in the free bending process, the size of the V-groove opening should be 8 times the thickness of the metal material.
2. * * Holding time * *: Holding time is one of the key factors in controlling the quality stability of processed parts. The length of holding time needs to be determined based on the hardness and thickness of the material, and reasonable settings can improve processing quality.
4、 Equipment maintenance and upkeep
1. Regular inspection and maintenance: Regularly lubricate, clean, tighten and maintain the equipment to ensure its normal operation and machining accuracy.
2. * * Tool replacement * *: Regularly check the wear of the tools, replace worn tools in a timely manner, and avoid affecting machining accuracy and stability.
5、 Personnel training and operating standards
1. * * Personnel Training * *: Regular skill training and safety education should be provided to operators to improve their proficiency and safety awareness in equipment operation.
2. * * Operation Specification * *: Develop detailed operation specifications, requiring operators to strictly follow the specifications to avoid equipment damage or decreased machining accuracy caused by misoperation.
By integrating the above measures, the machining accuracy and stability of the torsion axis CNC bending machine can be effectively ensured, and the machining efficiency and product quality can be improved.
