When taking linear guides directly with hands, it is necessary to thoroughly wash off sweat from hands and apply high-quality mineral oil before operation. Special attention should be paid to rust prevention during the rainy season and summer.​ Keep linear guides and their surrounding environment clean. Even tiny invisible dust entering the guides can increase wear, vibration, and noise of the guides.​ Linear guides must be installed carefully. Strong stamping is not allowed, direct hammering on the guides is prohibited, and it is forbidden to transmit pressure through rolling elements.​ For linear guides, use suitable and accurate installation tools. It is advisable to use special tools as much as possible, and strictly avoid using items such as cloth and short fibers.  Start by using assembly screws to loosely secure the linear guide’s bottom datum plane to the bed’s bottom mounting surface. Next, clamp the slide rail’s side datum plane against the bed’s side mounting surface with a vice to set the rail’s position. After that, use a torque wrench to tighten the fixing screws in order, applying a specified torque to ensure the rail’s bottom datum plane sits firmly against the bed’s bottom mounting surface.​ Set the linear gauge between the two linear guides. Use a dial indicator to align the gauge so it runs parallel to the reference side rail’s side datum plane. Then, use this gauge to align the driven side rail. Begin alignment from one end of the driven rail and tighten the assembly screws in sequence with the specified torque.​ Secure the two reference side sliders to a measuring platform, leaving just one slider on the driven side. At this point, neither the rail nor the slider should be fixed to the bed or platform. Attach a dial indicator to the top of the driven side slider and use it to measure the slider’s side datum plane. Start aligning from one end of the driven linear guide, tightening the assembly screws in order with the specified torque as you go.​ Fasten the two reference side rail sliders and one driven side rail slider to the platform. Then, loosely attach the driven side rail and its remaining slider to the bed and platform, respectively. Move the platform while using the reference side rail as a guide. Starting from one end of the rail, check the driven side rail’s rolling resistance as you tighten the assembly screws in sequence with the specified torque.​ Use specialized tools to position the driven side rail, then tighten the assembly screws in sequence with the specified torque.  Linear Guideways,Linear Guide Rail,Linear Guide Bearing,Bearing Linear Guide Suzhou Industrial Park Hojama Technology Co., Ltd , https://www.hojamax.comHojama High-accuracy Linear Guideways

Factors Affecting High Yield of Summer Maize
1. Poor Seed Selection
The current seed breeding system is still not fully developed, which leads to a significant proportion of substandard corn seeds in the market. Some farmers, seeking low prices, purchase what are claimed to be high-quality varieties from small traders or unofficial seed suppliers. This often results in poor germination rates and reduced yields, causing serious losses in production.
2. Inappropriate Planting Density
One of the major issues in summer corn farming is the excessive planting density. For instance, some farmers plant “Nongda 108†at more than 5,000 seedlings per 667 square meters (one acre), which is about one-third higher than the recommended density for this variety. Due to overcrowding, individual plants struggle to grow properly, leading to a higher rate of barren stalks and poorly filled ears. This also increases the risk of lodging, ultimately reducing overall yield.
3. Improper Fertilization Practices
Many farmers apply fertilizers in an unscientific way, with excessive use of nitrogen and insufficient attention to phosphorus, potassium, and micronutrients. According to the "law of the minimum," crop yield is limited by the nutrient that is in shortest supply. Overuse of nitrogen can actually reduce yields, as it weakens the plant’s resistance to lodging and makes it more susceptible to pests and diseases. Additionally, some fertilizers used are not suitable for corn, with inadequate levels of essential nutrients, further lowering productivity.
4. Inadequate Water Management
Some farmers rely on rainfall rather than the actual water needs of the corn plants. They may overwater during non-critical periods or fail to provide enough water during key growth stages. For example, they might water heavily when there's no real need, but neglect to provide sufficient water during droughts when it's most crucial. This inconsistent watering practice significantly affects the final yield and quality of the harvest.
