Traditional grinding method of linear guide rails

Publish Time：

2023-11-21

Reciprocating motion is achieved through guides, and the motion accuracy of rolling linear guides depends on the manufacturing accuracy of the linear guides. Grinding, as an important process in the processing of rolling linear guides, is of great significance in ensuring the manufacturing accuracy of rolling linear guides. There are mainly four methods for grinding rolling linear guides, and the last three are commonly used:

Method 1: Requires three processes to achieve grinding of the working surfaces of both sides of the raceway and the mounting base, and two side surfaces.

(1) Grinding the upper and lower surfaces and two side surfaces on a surface grinder;

(2) A surface grinder is equipped with a set of dressing devices. The workpiece is fixed with the mounting base and the side is corrected. One grinding head grinds the working surface of one side of the raceway;

(3) The workpiece is turned over, and the mounting base is fixed and the side is corrected in the same way. One grinding head grinds the working surface of the raceway on the other side. Due to accuracy and efficiency reasons, this method is rarely used.

Method 2: Two processes are used to achieve grinding of the working surfaces of both sides of the raceway and the mounting base, and two side surfaces.

(1) Grinding the upper and lower surfaces and two side surfaces on a surface grinder;

(2) The forming grinder is equipped with two sets of correction devices. The workpiece is fixed with the mounting base and the side is corrected. Two grinding heads grind the working surfaces of both sides of the raceway respectively.

Method 3: Two processes are used to achieve grinding of the working surfaces of both sides of the raceway and the mounting base, and two side surfaces.

(1) Grinding the mounting base and top surface on a surface grinder;

(2) The forming grinder is equipped with two sets of correction devices. The workpiece is fixed with the mounting base, and two grinding heads complete the grinding of the two side surfaces and the working surfaces of the two sides of the raceway at one time.

Method 4: Two processes are used to achieve grinding of the working surfaces of both sides of the raceway and the mounting base, and two side surfaces.

(1) Grinding the mounting base on a surface grinder;

(2) The forming grinder is equipped with three sets of correction devices. The workpiece is fixed with the mounting base, and two grinding heads complete the grinding of the two side surfaces and the working surfaces of the two sides of the raceway at one time, and the third grinding head completes the grinding of the top surface of the guide.

Linear guide rail - stainless steel guide rail

Due to different working environments, there are different requirements for linear guides. Let's talk about stainless steel linear guides. Although not widely used, common brands such as THK, HTPM, and HIWIN all offer stainless steel linear guides, but only a few models are made of stainless steel. There are many short videos online introducing linear guides. These videos are short and fast-paced, requiring multiple viewings to fully understand. While they may seem informative at first glance, upon closer examination, they lack significant in-depth knowledge (personal opinion). Let's discuss the advantages and disadvantages of stainless steel guides. The advantages of stainless steel guides mainly include: 1. Strong corrosion resistance: They maintain stable performance in humid and corrosive environments, resisting oxidation, reduction, and acid-base erosion. 2. Good wear resistance: The surface is specially treated, providing high wear resistance, suitable for high-load, high-speed operation, and extending the service life. 3. High precision and stability: They enable precise sliding and positioning, improving production efficiency and product quality. 4. Strong load-carrying capacity: They can withstand significant loads and impact forces, meeting the needs of various applications. 5. Wide range of applications: They are widely used in chemical, marine engineering, food processing, CNC machine tools, automated equipment, and industrial robots. However, there are also some drawbacks: 1. Higher cost and price: The high cost of stainless steel leads to relatively expensive guides. 2. Heavier weight: The high density and weight of stainless steel increase overall equipment weight and cost. 3. Difficult to process: The high hardness and toughness of stainless steel require special processing techniques and equipment, increasing processing difficulty and cost. In summary, stainless steel guides excel in corrosion resistance, wear resistance, precision, and stability, but are relatively costly and difficult to process. Selection should be based on specific application scenarios and requirements.

Linear guide rail replacement and repair case

Linear guide rail replacement and repair case

The following is a case study of replacing and repairing a linear guide rail: Customer feedback: "The equipment suddenly stopped moving left and right, so it needs repair." Therefore, we went to the site to replace the linear guide rail installed on the equipment. On-site confirmation: A device for processing profiles is installed above the linear guide rail. This device moves left and right using the linear guide rail to process the profiles. However, the guide rail on site could no longer move left and right, preventing it from working. It was visually apparent that the linear guide rail was damaged. When the equipment on the guide rail was lifted with a crowbar and the slider was removed, it was found to be damaged. Due to severe rusting at the mounting points of the slider and rail, it was difficult to remove the slider when disassembling it, which may have caused the damage to the linear guide rail. When we tried moving it again after replacing it with a new slider, the movement was still very poor. It is estimated that simply replacing the slider would not only cause it to be damaged again, but may also damage the rail and rack. Therefore, we informed the customer of the current condition of the equipment, the repair method and the quotation, and persuaded the customer to carry out further repairs. Repair process The equipment was lifted with a crowbar, and wooden blocks were placed under the workbench to prevent the equipment above from falling, and then the slider was removed. When trying to remove the slider, it was quite difficult to move it due to severe rust on the rail. Since the slider could not be removed smoothly, we first removed the rust using sandpaper and rust remover. (The rust on the rail made it difficult to move the slider; if the slider was forcibly moved, it could be damaged.) After the repair and test run, the workbench of the profile processing equipment ran smoothly. Suggestions on how to prevent recurrence of faults Regular inspection of transmission parts is very important to prevent unexpected damage. As a preventive measure, it is recommended to lubricate the guide rail regularly. If not dealt with in time, this kind of rust will occur, which may lead to equipment failure. (Construction site: Gunma Prefecture, Japan) The above is the main content of the repair report. This is a very common after-sales service scenario. Therefore, the questions are: 1. The report believes that the main cause of the failure is rust on the guide rail. Do you agree with this reason? 2. The corresponding measures in the report are: replacing the slider and removing rust from the rail. Is this OK? If you have better suggestions, please leave your comments and suggestions.
