The brake drum is a key component in the automobile brake system, and its machining accuracy directly affects the braking effect and driving safety.Generally speaking, the shape and position tolerances of the brake drum such as cylinder degree and roundness are required to be high. Usually, the cylinder degree tolerance should be controlled within 0.03mm-0.05mm, and the roundness error should also be in the range of 0.02mm-0.04mm.At the same time, the inner hole and outer circular surface roughness of the brake drum are required to reach Ra1.6-Ra3.2µm to ensure good contact and friction properties with brake shoes and other components.
CNC vertical lathe plays an important role in the process of processing brake drums, from pre-preparation to processing process control to quality inspection. The following is a specific introduction:
| Advantages of CNC vertical lathe processing | High-precision machining | The high-precision positioning system and servo drive system of the CNC vertical lathe can accurately control the trajectory of the tool to ensure that the cylinder, roundness and other shape and position tolerances of the brake drum meet the requirements.For example, a CNC vertical lathe with high-precision ball screw and linear guide rail has a positioning accuracy of ±0.01mm and a repeat positioning accuracy of ±0.005mm, which can effectively reduce the machining error of the brake drum. |
| High efficiency processing | CNC vertical turning can realize automated continuous machining, and by optimizing the tool path and cutting parameters, the machining time can be greatly shortened.For example, during roughing, a large-feed tool can be used to quickly remove most of the margin, and then during finishing, high-precision tools can be used for fine machining to improve processing efficiency. | |
| Complex shape processing ability | Brake drums sometimes have some complex structures, such as cooling ribs, mounting holes, etc.CNC vertical lathe can realize the precise machining of these complex shapes by writing complex machining programs to ensure the structural integrity and functional reliability of the brake drum. | |
| CNC vertical lathe processing technology | Clamping and positioning | Use a specially designed fixture to accurately clamp the brake drum blank on the workbench of the CNC vertical lathe to ensure that its axis coincides with the axis of the machine tool spindle, and at the same time ensure that the clamping is firm to prevent displacement during processing. |
| Roughing | According to the material and size of the brake drum, select the appropriate tool and cutting parameters for roughing, quickly remove most of the margin, and leave 0.5mm-1mm processing margin for finishing. | |
| Finishing | After the roughing is completed, replace the high-precision finishing tools, finish the inner holes, outer circles and end faces of the brake drum, and strictly control the dimensional accuracy and surface roughness. | |
| Hole machining | For the mounting holes on the brake drum, etc., the drilling, boring and other functions of the CNC vertical lathe can be used for processing to ensure the positional accuracy and dimensional accuracy of the holes. | |
| Quality inspection and control | Online detection | Some advanced CNC vertical lathes are equipped with online inspection systems, which can measure the size and shape tolerance of the brake drum in real time during the processing process. Once the deviation is found to exceed the allowable range, the system will automatically compensate or adjust to ensure the processing quality. |
| Offline detection | After the processing is completed, precision measuring equipment such as three-coordinate measuring instruments are used to conduct a comprehensive inspection of the brake drum, including dimensional accuracy, shape and position tolerance, surface roughness, etc., to ensure that the product quality meets the requirements of the standard. | |
| Quality control measures | Establish a perfect quality control system, strictly monitor every aspect of the processing process, and regularly maintain and test the accuracy of the CNC vertical lathe to ensure that the equipment is in good operating condition. |
