The present invention relates to a mobile horizontal cutting machine for processing the upper surface of the base plate of the press and forging machine, and more particularly, to maintain the horizontal by cutting the irregular upper surface of the base plate to a certain thickness, fine in the horizontal direction as well as the vertical direction It is possible to adjust the thickness to be cut according to the adjustable, and to provide a sliding horizontal cutting machine to improve the durability by installing a sliding bearing to reduce the coefficient of friction of the sliding moving parts.

In forging, a press machine or a forging machine is provided with a base plate for supporting a workpiece. The base plate described above should be maintained in precision, and as the production of the workpiece continues, the flatness of the top surface is not uniformly made due to wear, resulting in economical loss as the defective rate of the workpiece increases. Therefore, there is a problem in that the base plate must be replaced periodically if the workpiece is produced over a certain amount.

As the base plate is periodically replaced, the economic burden on the user is considerable. Recently, the top surface of the irregularly distorted and deformed base plate is cut using a cutting machine to cut the upper surface of the base plate to a certain thickness. come.

However, when working with a cutting machine as described above, it was difficult to keep the horizontal plane constant and cut when the area of the base plate was large. In other words, the base plate used in the large press machine or forging machine has a very large size, so it is very difficult to cut the top surface of the base plate while maintaining a constant horizontal plane. Of course, there are additional problems such as labor costs increase due to long working hours.

In addition, between the rail and the rail of the transfer device for moving the cutting machine in the horizontal direction is provided with a wedge-shaped gib to reduce the friction force, which must be replaced periodically because the surface of the gib wears for a long time, There is a disadvantage that must continuously supply lubricants.
