As our living standards have improved, there are more and more new materials appearing in our lives. PP honeycomb tool case liner is one of the emerging materials that are widely used nowadays. In the packaging industry, PP honeycomb tool case liner plays a very important role. Not only that, the color and appearance of the honeycomb board have also been continuously improved. Now, there are many different colors of PP honeycomb tool case liner on the market, meeting the needs of people for use in different occasions. Let's take a look at the process design of PP honeycomb tool case liner.
There are several types of honeycomb board boxes, such as paper honeycomb board boxes, fiberglass reinforced plastic honeycomb board boxes, and metal honeycomb board boxes. The panel is similar to the flange of a bent I-beam, and the honeycomb core is equivalent to the web of an I-beam, bearing shear loads. By increasing the panel spacing to enhance the structural stiffness, the design requires that the honeycomb core should have sufficient strength to withstand transverse shear stress, and it should also be thick enough and have a sufficiently large shear modulus to prevent the overall instability of the loaded sandwich structure. It has also been found that the center frequency of the band gap is consistent with the equivalent physical model of a spring oscillator around the center of mass, and the natural frequency of the deflection vibration is basically the same as that of the spring oscillator vibrating up and down at the edge frequency.

Process optimization plan for the warping and wave deformation of the OEM heater aluminum heatsink fin strips
The fin strips of the plate-fin type OEM heater aluminum heatsink are extremely thin and made of soft material. The warping and deformation after cutting are mostly caused by cutting stress, uneven pressing, tension disorder, and equipment accuracy deviation. It is necessary to optimize and rectify from multiple dimensions such as equipment, process, and parameters. Firstly, eliminate the cutting stress deformation. The ultra-thin fin strips will generate instantaneous shear stress during high-speed cutting, and uneven stress distribution will cause wave warping. It is necessary to reasonably reduce the cutting speed and adopt a uniform and low-speed cutting process to avoid sudden stops and starts, variable-speed cutting, and at the same time optimize the tool gap parameters to prevent material compression by the knife edge and reduce mechanical stress residues, thereby reducing the probability of deformation from the root cause. Secondly, adjust the pressure system to ensure balanced pressure. Local wear of the pressure roller, uneven pressure, and deviation of the pressure position will cause asymmetric force on the fin strips during cutting, resulting in excessive permanent warping on one side. It is necessary to thoroughly inspect the wear condition of the pressure rubber rollers, replace the aged and deformed rollers, precisely adjust the left and right pressure, and ensure that the fin strips are evenly and uniformly pressed without local suspension or local overpressure. Thirdly, optimize the tension control logic. Excessive tension during winding and unwinding is prone to stretching the fin strips and causing extension deformation, while too little tension will lead to loose and shaking of the roll material and the appearance of wave patterns. For different material characteristics of aluminum fins and stainless steel fins, dedicated constant tension parameters are set. For thin aluminum fins, micro-tension control is adopted, and for stainless steel fins, the tension is moderately increased to ensure smooth and non-stretched transportation without relaxation. Finally, correct the accuracy of the equipment frame and the knife shaft. Equipment frame tilt, excessive deviation of the knife shaft, and uneven height deviation of the conveying rollers will cause the fin strips to be subjected to biased force during cutting, resulting in regular wave deformation. It is necessary to level the equipment frame, calibrate the coaxiality and radial deviation of the knife shaft, and ensure that the cutting plane is flat and uniform. After process optimization, the finished fin strips are flat without deformation, which can directly meet the requirements of automated stacking and pressing production for the plate-fin type OEM heater aluminum heatsink.

The custom grid knurling cutter is a core component in fields such as grain processing and feed production, and its condition directly affects production efficiency and material quality. To determine if it needs to be replaced, one must avoid the dual pitfalls of "replacing too early, wasting costs" and "replacing too late, causing faults". A comprehensive assessment should be conducted from four dimensions: surface wear, functional performance, equipment operation data, and compliance. The following are specific judgment methods and standards.
1. Surface wear degree: The most intuitive and core basis for judgment
The function of the custom grid knurling cutter relies on the abrasive texture on its surface. If the wear exceeds the critical value, it will directly fail. First, the texture depth can be detected: use a depth gauge with an accuracy of 0.01mm or a dedicated texture ruler to evenly select 3-5 detection points around the roller body's circumference (avoiding bearing positions), and measure the height difference between the texture protrusions and depressions. Different processes have different requirements for texture depth. For grain deshelling, it should be ≥ 0.3mm, for fine grinding, it should be ≥ 0.2mm. If the average depth is lower than 50% of the initial depth, or if the texture on a certain area is completely worn flat (depth < 0.1mm), then it needs to be replaced. For example, if the initial texture depth of the new roller is 0.5mm, and the average depth after use drops to 0.2mm, and the depth of the 3 detection points is < 0.15mm, it is no longer able to meet the requirements for material grasping and shearing, and it needs to be replaced immediately.
Second, pay attention to surface damage: if irreversible damage occurs, it should be directly judged as needing replacement. For example, if local pits or scratches have a depth > 0.5mm and an area > 5cm², the surface flatness will be affected, causing uneven force on the material; if the coating or chrome layer peels off with an area > 10%, the exposed base material has low hardness and the wear speed will accelerate, and it may also contaminate the material; if a crack with a length > 5mm is detected using a penetrating penetrant testing agent, even if the surface is not obvious, the internal crack will expand during operation, causing a risk of roller body fracture.
2. Functional performance: Judging the condition of the roller body from the production results
If the surface wear has not reached the critical value but there are continuous deteriorating material handling problems in production, and other factors such as gap adjustment and moisture content of the material have been ruled out, it is necessary to determine replacement. In the deshelling or deshelling scenarios, if the residual skin rate of the material exceeds the process standard (such as wheat residual skin rate > 3% and corn residual skin rate > 5%), adjusting the gap between rollers and the speed ratio still does not improve; in the grinding scenario, the particle size deviation is large, the proportion of over-coarse or over-fine materials exceeds 10% and 8% respectively, and the yield of qualified materials after screening decreases > 15%; for non-moisture-related issues (with moisture controlled at 13%-14%), frequent roller surface material adhesion occurs, requiring every 30 minutes to stop the machine for cleaning, which seriously affects continuity. These situations all indicate that the custom grid knurling cutter is no longer able to meet production needs.
At the same time, abnormal energy consumption and efficiency also need to be vigilant. Under the same material and production capacity, if the equipment current continuously increases > 10%, it indicates that the roller surface wear has led to a decrease in friction force, requiring a greater pressure or speed to maintain the effect, and in the long term, it will lead to generator overload; if the processing time per unit product increases > 20% and there are no other faults such as belt slipping or bearing jamming, it also means that the function of the custom grid knurling cutter has declined.
3. Equipment operation data: Warning signals for hidden faults
Some wear or damage is difficult to be directly observed, and it needs to be judged in combination with the equipment operation parameters. Measure the horizontal and vertical vibration velocities at the bearing seat of the roller body using a vibration detector. Normal values should be ≤ 0.1mm/s. If the vibration speed exceeds 0.2mm/s continuously, and bearing lubrication is adequate and factors such as material impurities are excluded, it is likely that uneven wear on the roller surface has caused imbalance in dynamic balance. Continuing to use it will exacerbate bearing wear and even cause bending of the roller shaft.
It is also crucial to establish an account ledger for the use of custom grid knurling cutters. Record the replacement time, total processing material volume, and maintenance status. For alloy cast iron rollers in grain processing, the normal service life is approximately 800-1200 hours (processing volume 800-1200 tons), while for oil-resistant coated rollers in feed production, it is about 500-800 hours (processing volume 500-800 tons). If it exceeds the corresponding lifespan by 10%, even if there is no obvious surface wear, there may be fatigue damage internally, and the risk of sudden failure is high.
Four. **And Compliance Risks: The Unbreakable Bottom Line
The food and grain industries must strictly adhere to the compliance bottom line. If the surface of the roller body shows rust or coating detachment, it may cause heavy metals or coating particles to mix into the materials, violating the "Metal Materials and Products for Food Contact" (GB 4806.9) standard; if there are minor cracks on the roller body (length < 5mm) or the connection between the roller shaft and the roller body is loose (with obvious gaps during shaking), continuing to use it may cause the roller body to crack during high-speed operation, triggering an accident. Even if the function is still acceptable, it is necessary to force replacement.
Through multi-dimensional assessment, one can accurately determine the replacement timing of custom grid knurling cutters, ensuring stable production and material quality while maximizing the utilization of the roller body's lifespan and controlling production costs.

Stainless steel is a widely used difficult-to-machine material in mechanical processing. Austenitic, martensitic, and duplex stainless steels are extensively used in fields such as chemical engineering, aviation, and medicine due to their corrosion resistance and high strength. However, these materials have high plasticity and toughness, and their thermal conductivity is only about 1/3 of 45 steel. During cutting, they are prone to severe work hardening, chip formation, and tool bonding wear. Reasonable selection of TS-30 dual spindle CNC lathe is the core for ensuring processing quality and improving efficiency.
The selection of tool material is the foundation. For rough machining of stainless steel, the cutting load is high and the impact load is numerous. It is advisable to use WC-Co type hard alloy tools with balanced toughness and wear resistance, such as YG8 and YG6 grades with cobalt content of 8%-12%. These tools have strong impact resistance and are suitable for intermittent cutting during rough turning, capable of withstanding the heavy load of austenitic and martensitic stainless steel. If machining harder martensitic stainless steel (HRC40 or above), fine-grained or ultra-fine-grained hard alloys can be selected, such as YG6X. After grain refinement, the wear resistance is improved, effectively reducing tool wear. In the finishing stage, coated hard alloy tools should be used first, as the TiAlN coating has high temperature stability and low friction characteristics, which can form a heat-insulating lubricating layer during high-speed cutting, reducing chip formation and suitable for most stainless steel finishing. It should be noted that hard alloys containing titanium (such as YT types) are prone to chemical affinity with nickel and chromium elements in stainless steel, intensifying adhesion and wear. Generally, they are not used for austenitic stainless steel processing. For high hardness (HRC55 or above) stainless steel finishing, cubic boron nitride (CBN) tools can be selected. They have high hardness, good thermal stability, and weak affinity with iron elements, enabling high-speed hard turning and replacing the high-cost grinding process. However, the cutting allowance needs to be controlled to prevent chipping.
The optimization of tool geometric parameters is also crucial. The selection of the rake angle should take into account both cutting deformation and tool strength: for rough machining, a larger rake angle of 10°-15° is chosen to reduce chip deformation and lower cutting force; for finishing, the rake angle is further increased to 15°-20° to suppress sticking and improve surface quality. The clearance angle is generally set at 6°-10°. A too small clearance angle will intensify the friction between the tool and the workpiece, while a too large one will reduce the strength of the tool tip. The tool tip radius arc affects surface quality and life: for finishing, a small radius of 0.2-0.4mm is selected to reduce residual height and reduce roughness; for rough machining, a large radius of 0.8-1.2mm is selected to increase tool tip strength and adapt to heavy cutting. In terms of the main included angle, when machining thin-walled stainless steel parts, a large main included angle of 75°-90° is selected to reduce radial cutting force, avoid workpiece deformation, and improve the chip flow direction, reducing the impact on the tool.
The selection of tools also needs to be combined with the cutting process: during rough machining of stainless steel, low rotational speed (500-800r/min) and large feed rate (0.2-0.3mm/r) are used, combined with extreme pressure cutting fluid for cooling, to reduce the accumulation of cutting heat; during finishing, the rotational speed is increased to 1500-3000r/min, with a small feed rate (0.05-0.1mm/r), to ensure processing accuracy. During the machining process, chip breaking should be timely to avoid long chips entangling the tool, which can be optimized by adjusting the main included angle and edge inclination angle to further improve the chip-breaking effect and extend tool life.
