Aluminum alloy die-casting process knowledge
1) Aluminum alloys can be divided into four types according to their performance characteristics and uses:
Rust-proof aluminum (LF), hard aluminum (LY), super hard aluminum (LC) and forged aluminum (LD)
2) Cast aluminum alloys can be divided into four types according to the addition of main alloying elements:
Aluminum silicon system (AL-Si), aluminum copper system (Al-Cu), aluminum magnesium system (Al-Mg) and aluminum zinc system (Al-Zn)
Common grades are ADC12 (A383), ADC10 (A380)
3) Advantages of aluminum alloy die-casting
Good product quality: high dimensional accuracy of castings, good surface finish, high strength and hardness, the strength is generally 25~30% higher than sand casting, but the elongation is reduced by about 70%, the size is stable, and the interchangeability is good. Thin-walled and complex aluminum castings can be die-cast, for example: the current minimum wall thickness of zinc alloy die-casting can reach 0.3mm, and aluminum alloy die-casting can reach 0.5mm. High production efficiency: The machine has high productivity. For example, the domestic JⅢ3 horizontal cold air die-casting aluminum machine can die-cast aluminum 600 to 700 times in eight hours on average, and the small hot chamber die-casting aluminum machine can die-cast aluminum 3,000 to 7,000 times every eight hours on average. Excellent economic effect: Due to the advantages of die-casting aluminum parts such as precise size and smooth surface. Generally, they are used directly without mechanical processing, or the processing volume is very small, so it not only improves the metal utilization rate, but also reduces a large number of processing equipment and working hours. The casting price is cheap, and combined die-casting aluminum can be used with other metals or non-metallic materials, which saves assembly time and metal.
4) Disadvantages of aluminum alloy die-casting
During die-casting, due to the high speed of liquid metal filling the cavity and the unstable flow state, the general die-casting aluminum method is used, and the casting is prone to pores and cannot be heat treated. For castings with complex concave, die-casting is more difficult. The life of aluminum alloy die-casting molds is low, and the life is about 80,000 times. It is not suitable for small batch production. The main reason is that the manufacturing cost of die-cast aluminum molds is high and small batch production is not economical. Aluminum alloy die-casting is not easy to achieve anodization. Since many bubbles or sand holes are easily left after die-casting, the appearance cannot be well repaired, and the appearance cannot be covered after oxidation.
Note: Here we focus on the number and life of aluminum die-casting molds, the grade of die-cast aluminum, and the reasons why the appearance cannot be oxidized.
Die-casting molds must be made of hot mold steel. Commonly used steels are: H13, 8407, 2344, 8418, SKD61, DAC, FDAC, etc. After the product is formed, subsequent water inlet punching, removal of burrs, tapping, thermal shaping, etc. are required to obtain the primary product that meets the design requirements.
Tips:
1) When designing the structure of aluminum alloy die-castings, try to design as few inclined top structures as possible to prevent the subsequent removal of burrs from being difficult.
2) When designing the structure of aluminum alloy die castings, it is also necessary to pay attention to the uniform thickness of the glue and the smooth flow of the glue, which can reduce many problems such as poor appearance caused by molding and increase subsequent polishing and re-inspection.
3) When designing the load-bearing structure, it is still necessary to consider the structural strength, otherwise it is easy to break.

Effective Strategies to Quickly Increase Green Speed
Green speed is an important indicator of green quality, and many golf courses face the challenge of not meeting the required speeds for different tournaments. Here are some short-term effective methods to enhance green speed:
Adjust Mower Bed Knife Angle: Increasing the front angle of the bed knife can improve post-mowing green speed and enhance the smoothness of the cut. A high-quality bed knife for mowers can make a significant difference in achieving better cutting results.
Temporary Cleansing: By raising the height of the grooming brush, you can avoid disturbing the soil while also increasing the gap between the reel and the bed knife to reduce equipment load and improve cut uniformity.
Change Cutting Direction: Utilizing a cross-cutting pattern and reverse mowing can enhance upright grass growth and ensure a level hitting surface, thus increasing speed.
Moisture Control: Reduce automatic irrigation and opt for manual watering to prevent localized wetness, helping to keep the greens dry and speedier.
Adjust Mowing Height: Properly lowering the mowing height according to the 1/3 cutting rule can avoid damaging the turf while enhancing speed.
Adjust Mowing Frequency: Increasing the frequency of mowing, especially by mowing twice a day during high-speed demands, improves grass density and smoothness.
Optimize Mowing Speed: Choosing the right mower and blade type, and ensuring the mowing speed matches the grass height, can enhance cutting quality. A precision bed knife for golf course greens is crucial in ensuring a clean and even cut for better results.
Maintain Sharp Blades: Keeping the bed knife and reel sharp, along with proper blade spacing, ensures a clean cut and improves green speed. Regular sharpening is essential for maintaining the effectiveness of a durable bed knife for golf course mowers.
Rolling: Rolling the greens is an effective and safe method for quickly improving speed; studies show significant differences in speed before and after rolling.
Implementing these strategies can effectively increase green speed to meet tournament requirements.

Bedknife Sharpening Of Reel Mower
If replacing the bedknife it is important to use the following procedure:
1. Remove the bedbar from cutting unit.
2. Remove the screws from the bedbar using a socket wrench and a bedknife screw tool. Discard the screws.
3. Use a scraper to remove all rust, scale and corrosion from bedbar surface.
4. Lightly oil the bedbar surface before installing the bedknife.
5. Make sure that screw threads in the bedbar are clean.
IMPORTANT: Do not use an impact wrench to tighten the screws into the bedbar.
6. Use new screws to secure bedknife to bedbar. Apply antiseize lubricant to the threads of new screws. Do not apply antiseize lubricant to the taper of the screwheads.
7. Install all screws but do not tighten.
8. Using a torque wrench and bedknife screw tool, tighten the 2 outer screws to 10 in- lb (1 N-m).
9. Working fromthe center of the bedknife toward each end, tighten screws from 200 to 250 in- lb (23 to 28 N- m).
10. Grind the bedknife after installing it to the bedbar.
Since there can be variations in the mounting surface of the bedbar, it is necessary to grind the bedknife after installing it to the bedbar.
When grinding the bedknife, remove only enough material to make sure the top surface of the bedknife is true. Be careful not to overheat the bedknife. Remove small amounts of material with each pass of the grinder. Also, clean and dress grinding stone often during the grinding process.
Because the top grind angle on bedknives is critical for edge retention, and therefore after- cut appear ance,Using special service tools for accurately measuring the top grind angle on all bedknives.
IMPORTANT: Do Not grind the bedknife below it’s service limit. Operating the cutting unit with the bedknife below the service limit may result in poor after- cut appearance and reduce the structural integrity of the bedknife for impacts.
A lead-in chamfer provides a softened entry for the leading side of the reel blade helix as it approaches the bedknife. This helps eliminate rifling caused by heavy contact and vibration. A lead- in chamfer is ground into all new Reelmaster bedknives. The original chamfer should last for the first 40%of the bedknife service life. Check and re-grind the lead- in chamfer as necessary.
The idea is to get a grind in place without spending a lot of time making sure it is exact. Using a file to make the lead-in is a perfectly acceptable method. It is important not to make the lead-in too long or you will notice that there is a streak left behind at the edge of the cutting unit as the reel will not cut well in the area
of the grind or may adversely affect the overlap area.
The Edge Max bedknife includes a leading edge of harder steel.
The Edge Max bedknife Holds an edge twice as long as a standard bedknife, and reduces the need for adjustments, backlapping and grinding.
Set the bedknife to reel adjustment on an Edge Max bedknife as usual. Light contact while running on the ground.
There are no other special requirements.
A dull knife must be sharpened.
If backlapping is part of your maintenance practice, be prepared to backlap for two to three times the amount of time as compared to a standard bedknife. Front face grinding is acceptable in moderation.
Any facing or grinding must be done with exacting tolerances. Do not use a hand held grinder
Using a diamond grinding wheel is recommended to prevent overheating or damaging the bedknife edge while grinding.
Dress the stone more frequently. Before starting, and at least once during grinding. One pass to dress. Multiple passes will cause the stone to load up.
When grinding, remove smaller amounts of material
(a shallower cut).
Expect a different spark pattern.
Bedknife design must allow for maximum material to dissipate heat and yet allow the remaining uncut grass under the bedknife.
Unfortunately, there is no set rule for space left under the knife, nor can there be. This is due primarily to surface density and turf conditions. There is no measurable plane that works, other than, your mower, in your turf.
The only thing that is absolute is that while on the bench, the bedknife can not touch the height of cut adjusting tool. There must be a reasonable space between the bedknife and height of cut adjusting tool.
To look at that in a different manner, place the cutting unit on a table resting on the rollers so as you can look at the end of the cutting unit. The bedknife can not touch the table top. This is the absolute! Everything else depends on the agronomic conditions of the turf.
Listed here are popular Greens mower bedknives and their recommended operating range.
Due to the height of cut variations on a fairway and the requirements of cutting conditions there is another line of bedknives for the fairway or higher height of cut ranges.

Guide to Installing and Replacing Lawn Mower Blades
Lawn mowers are familiar to everyone, as they are widely used for gardening and trimming. However, the installation and replacement of lawn mower blades is also an important issue. Due to prolonged operation, lawn mower blades can easily experience wear and misalignment. Properly installing the blades ensures the machine operates smoothly and avoids problems such as vibrations and poor trimming quality during use.
How to Install Lawn Mower Blades
1. The lawn mower blade has a large nut used to secure it. When installing, place the blade onto the mower's deck and tighten the nut, using a torque of 30-40 N·m.
2. Once completed, place the lawn mower on a stable surface and pull the starter cord a few times to ensure there is no fuel in the cylinder before starting.
3. Clean the mower blade, blade holder, and the interior of the mower from dirt and debris, then install the blade holder, blade, and blade bolts.
4. Firmly hold the blade to ensure it makes contact with the blade's drive surface. Tighten the blade bolts with a torque of 50-60 N·m.
Note: The blade bolts are specially designed and should not be replaced with other types of bolts. When viewed from below, the blade rotates counterclockwise; ensure the cutting edge is facing this direction during installation.
How to Replace Lawn Mower Blades
1. When replacing the lawn mower blade, first take a positioning rod and align the small metal cover on the blade head with the positioning hole inside, then insert the positioning rod.
2. Below the blade, there is a large nut used to secure the blade. After securing the mower's blade head, use a wrench that matches the blade head nut to unscrew the fixed screw beneath the blade head.
3. Once the screw securing the blade head is removed, proceed to take off the metal cover underneath the screw.
4. After removing the metal cover, you will see a thicker metal washer underneath; remove this washer as well. Once all the above components are removed, you can successfully take off the lawn mower blade.
5. Next, place the new blade onto the spindle, then reinstall the components that were just removed in reverse order, and finally tighten the screws. This completes the blade replacement for the lawn mower.

How to deal with the problems arising in using a dressing machine
When using a combs, you may encounter various problems. To help you better deal with these problems, we will elaborate on the following aspects.
- Blade wear problem Blade wear is one of the most common problems in the use of grass bursers. Especially when dealing with hard forage, the blade is easily damaged. The worn blade may cause the forage to not be completely cut, thus reducing the operation efficiency of the machine. To solve this problem, we need to check the blades regularly and replace or sharpen the knives if necessary. In addition, a proper adjustment of the cutting height and feeding speed can also help to reduce the blade wear.
- Uneven speed of feeding in forage The speed of feeding the performance and efficiency of the combs. If the feeding speed is too fast or too slow, it will cause the machine performance to decline. To address this issue, we need to ensure that the feeding volume is moderate and remains stable. During the actual operation process, the feeding speed can be adjusted according to the type of forage, moisture content and the performance of the machine.
- Stlag and abnormal sound problems In the process of using the grass grinder, sometimes there will be stuck or sound abnormal phenomenon. This may be due to loose fastening screw, incorrect connection position or hard objects such as metal and stone entering the machine. To avoid this, we should regularly check the screws and connection position and keep the machine clean. In addition, timely cleaning of hard objects and fastening screws can also effectively prevent such problems.
- Operational safety issues When operating the dressing machine, ensure the hand away from the grass roller to prevent accidental injury. If any blockage or other fault is found, stop and correct. Do not continue to use the machine in case of failure to avoid greater damage or safety accidents.
- Maintenance and maintenance of the grass-dressing machine To ensure the proper operation and efficiency of the combs, we need to follow the following basic maintenance recommendations: 1. After the work, clean the machine and add lubricating oil to the lubrication parts. 2. When not used for a long time, store the machine indoors or in a shed to prevent rain and exposure. 3. Check and maintain the machine regularly to ensure the normal operation of all parts.
Through the above five aspects, we hope to help you better understand and solve the problems in the process of use. As long as we operate correctly and maintain carefully, the grass grinder can exert better performance and provide strong support for our lawn maintenance work.
