Product Description
This machine is specifically designed for grinding long knives used in various industrial applications such as peeling machines, granulators, paper cutting tools, shearing blades, slicing knives, and more. It can handle knives with a maximum working length of 1500-7000mm, making it ideal for large-scale operations.
The machine features a sturdy gantry-style body constructed from high-quality steel, which has been stress-relieved to eliminate internal stresses. This ensures the structure maintains its strength and rigidity without deformation. The steel thickness is 10 or 12mm, providing excellent durability.
The grinding head is equipped with a dedicated motor that allows for precise axial gap adjustment, ensuring smooth operation and long service life. The vertical movement of the grinding head is controlled by a ball screw mechanism, guaranteeing high precision during the grinding process.
The worktable uses an electromagnetic chuck for secure clamping of knives, and the angle can be easily adjusted using a worm gear system. The linear guides are made by TAIWAN HIWIN, ensuring smooth and stable horizontal movement of the grinding head.
An inverter is used to control the speed of the grinding head, allowing for easy adjustment of both horizontal and vertical speeds. This makes the machine suitable for both fine and rough grinding tasks. The machine offers a high level of accuracy, up to 0.01mm.


Key Features
1. The worktable features an electromagnetic chuck with strong magnetic power and low energy consumption.
2. A double tilting fillet design ensures the chuck is tightly locked, enhancing the stability of the machine.
3. The rack drive system ensures smooth and steady movement of the grinding head.
4. Buttons are sourced from Siemens, known for their reliability and ease of use.
5. Switches and contactors are made by French Schneider, renowned for their quality and durability.
6. The grinding head movement is controlled by an inverter, with a speed range of 0-20m/s, adaptable for both precise and rough grinding.

PU resin is one of the most suitable base materials for ink.
It can provide the ink with good pigment dispersity, adhesive force, and some other performance like heat resistance, adhesion with OPP or PE film and so on.
PU resin of ink can be divided into 3 types because of the ink types, including inside composite ink, surface composite ink and water-based composite ink. But all of the them are suitable for gravure printing rather than other printing methods.
We have different resin which can be suitable for NC or ester. They can show various abilities like boiling water resistance, good adhesion with OPP, low odor and so on.
We can also provide suggestions about product formula.
PU resin, also known as polyurethane resin, is a type of synthetic resin that is widely used in the production of inks. It is a versatile material that offers various benefits for ink formulations.
One of the main advantages of using PU resin in ink is its excellent adhesion properties. It forms a strong bond with different substrates, including paper, cardboard, plastic, and metal, ensuring that the ink adheres well to the surface and resists smudging or rubbing off.
PU resin also provides good gloss and transparency, resulting in vibrant and visually appealing prints. It enhances the color intensity and clarity of the ink, making it suitable for high-quality printing applications.
In addition, PU resin offers excellent resistance to water, chemicals, and abrasion. This makes the ink more durable and long-lasting, ensuring that it remains intact even under harsh conditions.
Furthermore, PU resin can be formulated to have fast drying properties, allowing for faster production speeds in printing processes. It also has good flexibility and elasticity, which helps prevent cracking or flaking of the ink film.
Overall, PU resin is a popular choice for ink formulations due to its excellent adhesion, gloss, transparency, resistance, and drying properties. It is commonly used in various printing applications, including packaging, labels, decals, and graphic arts.
