Embedded-guide-rail linear sliding table with four-column arc type grooves

The invention discloses an embedded-guide-rail linear sliding table with four-column arc type grooves. The sliding table comprises an aluminum profile base and a sliding base, the sliding base is slidably installed in the aluminum profile base, the sliding base is made of a high-strength aluminum alloy material, two square groove openings are formed in the inner walls of the two sides of the aluminum profile base, two square groove openings are formed in the two sides of the sliding base, the square groove openings at the two sides of the aluminum profile base and the square groove openings atthe two sides of the sliding base are equal in spacing, structures of the two sides of the aluminum profile base and the sliding base are symmetrical, and embedded guide rails are fixedly installed in the square groove openings. According to the sliding table, the circular arc type grooves greatly reduce the differential sliding movement amount of steel balls, when prepressing of the steel ballsis enlarged, a four-column
