The application and advantages of double disc grinding machine in gear blade grinding
As an important part of the gear transmission system, the processing accuracy of gear discs directly affects the transmission efficiency, smoothness of operation and service life. In the production process of gear blade, flatness and thickness consistency are the key indexes, which need to be guaranteed by high-precision grinding equipment. Double disc grinding machine with its high efficiency and high precision processing ability, become one of the important equipment for gear piece grinding.
Working principle of double disc grinding machine
Double disc grinding machine is a kind of equipment that can grind the upper and lower two planes of the workpiece at the same time. Its core working method is to grind both sides of the workpiece clamped in the middle by the synchronised movement of the upper and lower rotating grinding wheels. The height and pressure of the grinding wheels can be flexibly adjusted according to the processing requirements to ensure that the workpiece achieves the ideal flatness and thickness during the grinding process.
Requirements for equipment for gear blade grinding
Gear discs, as precision mechanical parts, have strict requirements for flatness, thickness consistency and surface finish. The fulfilment of these requirements requires processing equipment with the following properties:
1. High flatness: Ensure smooth operation when gear discs are mated with other parts.
2. Thickness consistency: Ensure the meshing performance of the gear discs and avoid the reduction of transmission efficiency.
3. Surface finish: reduces friction loss during operation and improves service life.
Double disc grinding machine can perfectly meet the above requirements by virtue of its synchronous double disc machining feature, which makes it an ideal choice for gear blade machining.
Advantages of the double face grinding machine
1. High-precision machining
The double disc grinding machine adopts simultaneous grinding of upper and lower double grinding wheels, which effectively avoids warping and unevenness problems that may be caused by single face grinding. By precisely controlling the grinding pressure and grinding wheel speed, the flatness error of the gear piece can be controlled at the micron level, and the thickness consistency reaches the industry leading level.
2. High-efficiency production
The machine is able to process both the upper and lower surfaces simultaneously, which significantly reduces the processing time and improves the production efficiency. This has significant time and cost advantages for gear sheet processing companies that require mass production.
3. Superior surface quality
Gear discs ground on grinding machines have a higher surface finish, reducing the complexity of subsequent processing steps and laying the foundation for overall quality improvement of gear discs.
4. High degree of automation
Modern double disc grinding machines are usually equipped with automatic feeding, cooling and inspection systems, which are able to ensure processing accuracy while reducing manual operations and improving production stability and reliability.
Typical application cases
After a machinery manufacturer introduced a double disc grinder into its gear sheet production line, it improved the machining accuracy to a flatness error of less than 3 microns, a thickness consistency error of less than 2 microns, and an increase in the qualified rate of finished products by 25%. At the same time, the processing efficiency increased by nearly 40%, significantly reducing the unit cost of production. This equipment upgrade not only optimises the production process, but also enhances the competitiveness of the enterprise's products in the market.
