Rubber Double Head Grinding Machine

1Rubber Double Head Grinding MachineProduct Overview

Grinding machine is a laboratory equipment specifically used for physical property testing and sample preparation of power cable materials such as cross-linked polyethylene and polyethylene plastics. Its main function is to uniformly polish the sample with a grinding wheel, making the surface of the sample smooth and flat, and meeting the requirements of various physical performance tests (such as tensile, wear resistance, dielectric strength testing, etc.). The device is designed reasonably and operates stably, using a dual grinding wheel structure with high polishing efficiency, which can meet the preparation needs of samples with different particle sizes and thicknesses.

The equipment is equipped with an efficient three-phase motor, which has strong power and stable speed, ensuring the continuity and consistency of the grinding process. Easy to operate, safe and reliable, widely used in cable production enterprises, scientific research and testing institutions, quality inspection centers, and university laboratories.

Compared with traditional manual polishing methods, this machine not only improves the efficiency of sample preparation, but also avoids human errors, ensures the uniformity of sample thickness and surface quality, and is one of the important equipment to ensure accurate and reliable experimental results.

4Plastic Double Head Grinding MachineInstructions for Use

1.Installation and preparation

•Place the grinding machine on a flat and sturdy workbench or ground to ensure its stability.

•Connect the three-phase 380V power supply and check if the motor direction is correct (consistent with the wheel markings).

•Install grinding wheels of appropriate specifications (choose 36 or 60 according to sample hardness and preparation requirements).

•Confirm that safety protection devices (such as grinding wheel covers) are in the correct position to prevent flying debris from injuring people during operation.

2.operation steps

•Fix or hold the sample in the work area and slowly touch the surface of the grinding wheel.

•Control the force to ensure even distribution of force on the sample and avoid excessive local polishing.

•Adjust the polishing time and position according to the sample preparation requirements until the sample reaches the required size and surface finish.

•If the grinding wheel needs to be replaced during the polishing process, the power should be cut off first, and the operation can only be carried out after the grinding wheel is completely stopped.

3.Shutdown and organization

•After the operation is completed, turn off the motor power first, and then unplug the main power plug.

•Clean the surface and residual dust of the equipment with a brush or compressed air.

•Regularly check the wear of the grinding wheel, replace it in a timely manner, and ensure the quality of sample preparation.

5Double head grinding machinePrecautions

•It is strictly prohibited to wear gloves when operating the grinding machine to avoid being caught in the grinding wheel.

•Operators should wear goggles and dust masks to avoid flying debris and dust from causing harm to the human body.

•Do not use grinding wheels with cracks or exceeding the wear limit to prevent accidents caused by wheel breakage.

•Before starting up, check if the power wiring is secure and ensure good grounding.

•When the equipment is running, avoid prolonged overload use to prevent the motor from overheating.

•Routine maintenance and cleaning should be carried out after each use to ensure long-term stable operation of the equipment.
