In the face of different materials and hardness of the parts, the turn-milling machine needs to adopt a series of adjustment and optimization strategies to ensure processing quality and efficiency. Below, I will tell you in detail!
First, tool selection and optimization
1. Tool material :
For softer materials, you can choose ordinary cemented carbide tools;
For materials with higher hardness, ceramic tools or CBN (cubic boron nitride) tools should be selected, which have higher hardness and wear resistance, and can effectively resist wear in the cutting area.
2. Tool shape and Angle :
According to the shape of the parts and processing requirements, design the appropriate tool shape, such as the number of tool blades, blade shapes and front angles;
Optimize the cutting Angle of the tool to improve cutting efficiency and machining quality.
two, cutting parameters adjustment
1. Cutting speed :
Select the appropriate cutting speed according to the material and hardness of the part;
In general, materials with higher hardness need to choose a lower cutting speed to reduce cutting heat and cutting force, to avoid excessive tool wear and material thermal deformation.
2. Feed speed :
The choice of feed speed also needs to consider the material and hardness of the parts;
Reasonable feed speed can ensure the stability of the cutting process and improve the processing efficiency.
As mentioned above, in the face of parts with different materials and hardness, the turn-milling complex needs to be adjusted and optimized by tool selection and optimization, cutting parameter adjustment, cooling and lubrication, spindle and clamping system adjustment, programming and process optimization and other strategies. The implementation of these strategies can ensure that the turn-milling machine can maintain efficient, stable and accurate machining performance when machining parts of different materials and hardness.
3. Depth of cutting :
The choice of cutting depth needs to be determined according to the size and processing requirements of the part;
Under the premise of ensuring the processing quality, increasing the cutting depth appropriately can improve the processing efficiency.
Cooling and lubrication
1. Cutting fluid selection :
According to the material and processing requirements of the parts, select the appropriate cutting fluid;
Cutting fluid plays a cooling, lubricating and cleaning role in the machining process, which is essential to improve the quality and efficiency of the processing.
2. Cutting fluid concentration and spraying method :
Adjust the concentration of cutting fluid and spraying method to optimize the cooling effect of the cutting area;
The suitable cutting fluid concentration and spraying method can effectively reduce the influence of cutting heat on the hardening of materials and improve the processing quality.
four, spindle and clamping system adjustment
1.one Spindle accuracy :
Ensure the accuracy and stiffness of the spindle to reduce vibration and errors during machining;
Regular maintenance and maintenance of the spindle to ensure that it is in working condition.
2. Clamping system :
According to the shape and size of the parts, choose the appropriate clamping method and fixture;
Ensure that the clamping system is stable and reliable to avoid loosening or displacement during processing.
Programming and process optimization
1. Optimize the cutting path :
According to the structure and material characteristics of the parts, the cutting path and cutting sequence are arranged reasonably;
Optimizing the cutting path can shorten the processing time and improve the processing efficiency.
2. Macro application :
Skilled use of macro programs for automatic processing and error compensation;
By writing general macro program, we can realize the automatic processing of parts of different models and specifications, and improve the processing efficiency.
