McGowdy Megalinear RPP8 HP timing belt is your ideal choice for high precision CNC machine tools

Tight tolerance requirements and efficient production capacity are essential for the manufacturing industry. In the machine tool industry, computer numerical control (CNC) machine tools are widely used. Through CAD and other process design documents, a series of continuous control instructions can be formed, and the CNC servo drive device can automatically complete drilling, boring, turning and other processing processes, and accurately process various materials such as metal, plastic, wood, and composite materials. Compared with the traditional manual control machine tool, this is undoubtedly a huge progress.

The CNC servo drive system not only needs to have high temperature resistance, impact resistance, corrosion resistance, but also can drive the machine tool smoothly and accurately to ensure the machining accuracy. Therefore, the drive system needs to have a high-speed, strong driving force, in order to play a sustained and stable performance.

Linear actuator is an electric drive device that converts the rotary motion of a motor into the linear reciprocating motion of a push rod. The housing is usually made of aluminum and has been widely used in CNC machine tools. The belt-type linear actuator is a special linear actuator mainly used in push-pull and lifting applications. It can be regarded as a rack and pinion device with a flexible rack, which can flexibly adjust the center distance of the pulley and drive different loads by pushing and pulling force.

Industry pain points:

A machine tool manufacturer found that the belt-type linear actuators used in their CNC products always had problems, making the processing quality unstable and the processed products unqualified. After research, it is found that the reason is that the synchronous belt used is always stretched and deformed. Not only can not meet the requirements of high-precision positioning, but also because of belt deformation, have to frequently adjust the tension, resulting in the belt is easy to break due to impact load.

The application of CNC machine tools for long-term large acceleration and thrust work obviously has extremely high requirements for the reliability and durability of the timing belt. Customers want to develop a cost-effective servo drive system with low maintenance, low noise, light weight, high efficiency and other characteristics. Obviously, the synchronous belt they are using now cannot meet the performance requirements.

mcgaudi solution:

After analyzing the drive unit, McGaudi's application engineer team recommend the Megalinear RPP8 HP high-strength PU (polyurethane) timing belt to the customer. Its high-strength galvanized steel wire core ensures that the actuator can achieve maximum tensile load and minimum elongation at break. Its S-twist Z-twist high-strength core arrangement can ensure that the timing belt always moves in a straight line; at the same time, the thermoplastic polyurethane belt with a hardness of 92 Shore A has the characteristics of light weight, wear resistance, fatigue resistance, and strong flexibility.

Program effect:

After the customer used McGaudi Megalinear RPP8 HP high-strength PU timing belt, the phenomenon that the belt was always stretched before was eliminated, thus solving the problem of inaccurate servo drive positioning. Moreover, because there is no need to frequently adjust the belt tension, the service life of the belt is greatly increased, and its driving performance is further improved.

The Megalinear RPP8 HP high-strength PU timing belt is ideal for CNC special belt linear actuators. Its durability and efficiency provide the best balance between performance, longevity and cost.
