Main characteristics
※ This machine tool applies to continuous grinding of various cylinders and cut grinding of cone and forming rotary parts,for the needs of bulk and mass production.
※ The main shaft bearing of the grinding wheel is 5 dynamic sliding type,with large bearing capacity and high hardness.
※ The main shaft bearing of guide wheel is 1:30 integral sliding type,with large bearing capacity and high precision.
※ The wheel frame can rotate horizontaly,so when grinding small parts,there is no need to adjust the grinding wheel into cone,so as to increase its utilization ratio and decrease trimming time.
※ The guide wheel gearshift is AC controlled,thus realizing non step adjustment.
※ Grinding and guide wheel trimmer reciprocating adopts hydraulic transmission and non step adjustment.
※ Equipped with automatic cut and grinding equipment,it can work semi-automatically periodically.

main features
The centerless grinder is composed of three mechanisms: grinding wheel, adjusting wheel, and workpiece support. The grinding wheel actually performs the grinding work and helps the workpiece obtain sufficient feed speed. When using this device, operators can arrange and combine these three mechanisms to create several coordinated working methods, which can be used to handle various different products.
With the development of the grinder industry, a type of centerless grinder with shortened horizontal dimensions has emerged. This equipment is particularly suitable for use in a small installation space and can handle products of various shapes, helping users save space. This grinder equipment greatly reduces the lateral size of the centerless grinder and meets the user's space saving requirements, as there is no need to maintain a space for the grinding wheel dressing unit on the side of the grinding wheel. The use of centerless grinding machines can help users improve the speed of operation and reduce the space requirements of the equipment. General grinding equipment has a large volume and occupies a large area, which is inconvenient for operators to use. The emergence of this type of grinder solves the problems of large footprint and difficult operation, and improves the efficiency of equipment use. Although the difficulty of using this equipment has decreased compared to other grinding machines, operators still need to strictly follow the instructions for use. Operators often overlook the startup operation of the device, causing significant impact on the equipment,
The operator of the Heartless Grinding Machine must do a good job of turning on the equipment before use, so as to improve the efficiency and prolong the service life of the equipment. Before starting up, check the surrounding condition of the machine. No items should be placed on the machine, and the workpieces should be arranged neatly. The neat arrangement of workpieces is beneficial for operators to pick up and use them. If the equipment is placed everywhere, it will affect the efficiency of employees' work. The operator also needs to check whether the container berth is normal, the water level of the cooling water tank, and the use of the grinding wheel are normal before starting up. Before starting up, it is also necessary to check whether there are any working objects or other debris in the machine tool. If other debris is found, it should be dealt with in a timely manner. Before starting up, it is necessary to check whether the switch of the equipment is reliable and confirm that the safety protection of the protective cover is still effective. Operators must understand the operation process of the equipment before turning it on, so that they can smoothly carry out their work.
