Talking about the difference between the hard machine and the track machine of blow molding machine

The hard rails refer to the castings where the rails and the bed are integrated, and then the rails are machined on that basis, ie the shape of the rails cast on the bed, the rails processed by quenching, grinding, and the bed and rails. Not necessarily one, such as inlaid steel rails, which are nailed to the bed after processing. Inlay rails (with some plastic rails) are used in heavy load cases. In particular, lubrication is a very important issue for it.

The characteristics of the hard rail machining center: The hard rail machining center is a sliding friction during machining, which is a surface contact, a large contact surface, a large friction force, a fast moving speed, and a large amount of cutting when machining cast iron cast steel. The force is relatively large, and the vibration is severe. At this time, the benefits of the hard rail are revealed. Because the hard rail surface is in contact with the surface, the contact surface is large, and the shock absorption is relatively good. It can ensure the processing efficiency and ensure the processing accuracy. The rigid rail machining center is rigid and suitable for heavy cutting. However, the disadvantage is that high-speed cutting cannot be performed.

The track usually refers to the rolling guide rail, which is currently used in the linear module used in the machine tool industry. The linear guide rail itself is divided into two parts: the slide rail and the slider. Inside the slider there are internal circulating balls or rollers. The length of the slide can be customized. It is a kind of modular component and it is a standardized serialized individual product produced by a specialized manufacturer. It can be installed on a machine tool and can be removed and replaced after being worn out. The track processing center is a machining center equipped with a rolling guide (or a linear guide).

The characteristics of the track processing center: The track processing center has a high speed of movement, low rolling resistance, no crawling phenomenon, and easy lubrication. After a long time use, the loss of precision is small. The line rail machining center processes rolling friction, point or line contact, small contact surface, and small friction. It is mainly used in high-speed machining and mold industry. For the small amount of cutting, the machining of the cutting tool is fast.

Ball line rail and roller line rail, the most important difference is the carrying capacity. Roller linear guides use cylindrical rollers in the slides, and the large contact area can withstand large loads. The ball linear guides use spherical rollers in the slides, which can withstand relatively small loads. The appearance of roller track can meet both high rigidity and high speed machining requirements.
