For minor flaws and scratches on the machine guide rails, as long as they are repaired with a scraper or grindstone, they can continue to operate. For gluing flaws, they need to be repaired by welding repair or filling and filling, and the welding of the machine guide rails. Repairing and sticking, the process is relatively complicated, especially for large-area repairs.
There are three major factors to consider when repairing machine tool guides
More comprehensive consideration should be considered before repair:
First, we must consider whether the repair process used has any influence on the accuracy and mechanical properties of the guide rail. If it is affected by temperature, will it cause deformation of the guide rail, whether it will change the mechanical strength of the guide rail and the surface hardness.
Second, we must consider the adaptability of the repair technology used for the guide rail material. For example, the guide rail of cast iron material generally does not use cast iron surfacing. Due to the poor weldability of cast iron, it is easy to produce defects such as cracks and pores, and it is not suitable for processing.
Third, we must consider the mechanical strength of the repair layer itself and the actual working environment of the guide rail. For machine tools with different specifications, different performances and different practical environments, suitable welding and bonding materials, advanced repair methods and new techniques should be used for repairing.
(Finish)Hot Cutting Extrusion Pelletizer
LINA Extrusion Pelletizer
Most of the polymer must be kneaded and then granulated before it is made into a final product. Sorted by pelletizing ways, LINA rubber & plastic granulator can be divided into four categories: 1. Hot-cutting and air-cooling pelletizing method. 2. Under-water granulating method. 3. Water-strand extrusion method. 4. Water-ring granulation method. LINA pelletizer can meet the granulation needs of high-viscosity and low viscosity rubber and plastic materials, as well as some new materials and chemical additives.
LINA Die Surface Hot Cutting Pelletizing Machine
LINA`s die surface hot cutting and air cooling granulating machine is suitable for polymers that are sensitive to heat and long residence time, such as PVC, TPR, PE, cross-linked PE and so on. The flow path of the polymer from the extruder to the pelletizing port should be kept as short as possible with minimal heat. When polymer is extruded through the die surface, the rotating blade cuts the extruded materials into particles. After the pellets are cut, they are removed from the rotary blade and caught by cooling air circulating in the pelletizing room. The air stream preliminary cools the surface of the pellets and takes them out of the pelletizing room and sends them to the cooling zone.

Advantage of LINA Pelletizing Line
1. The unit has the whole unit process chain, sound and light failure alarm and fast lock fault point and other control functions. All parts that are in contact with the material are made of stainless steel.
2. High accuracy of temperature control system to ensure the temperature sensitivity of the material.
3. It adopts the drop type separating method after cutting process, to avoid Particle agglomeration and ensure particle cooling.
4. Feeding system of the pressing machine adopts heater and reversing device to solve problem of power outage, material crash and cleaning.
5. Especially, the barrel and die head adopts advanced foreign techniques to ensure and control the dangerous occurred when the pressure is uncontrollable. The honeycomb filter plate is easy to clean and quickly change the mesh and the die head t easy to leak.
6. The hoist adopts automatic return technology to ensure the working efficiency.
7. The technological combination of dual-pull forced feeder and single screw not only meet the high requirement of secondary continuous mixing, but also solve the problem of time and power consuming of traditional working process.
