1999 EXCEL PMC5T18 VERTICAL MACHINING CENTER

Technical Description

The 1999 EXCEL PMC5T18 is a 3-axis vertical machining center manufactured by Kiwa Machinery of Japan and sold in North America under the Excel brand. The PMC designation references the Fanuc PMC subsystem integrated into the Fanuc 21-M control, and the 5T18 suffix denotes the 510 mm (20.1-inch) X-travel class and 18-station automatic tool changer. The machine is built on a BT40 taper spindle with 7.5 HP of continuous power and a maximum speed of 8,000 RPM — a higher RPM ceiling than the earlier EXCEL 510 — suited to aluminum, non-ferrous metals, and light steels where higher cutting speeds benefit surface finish and cycle time. Axis travels are 20.1 inches in X, 16.1 inches in Y, and 18.1 inches in Z, with a work table measuring 27.6 by 17.1 inches and a table load capacity of 660 lbs (300 kg). Rapid traverse rates are 945 IPM on X and Y and 787 IPM on Z, significantly faster than the earlier 510-series. Maximum tool length is 9.65 inches and maximum tool weight is 13.2 lbs. A 4th-axis wiring provision (M75 output) is included. Machine control is via a Fanuc 21-M CNC. Overall machine dimensions are 77 by 90 by 110 inches, and machine weight is approximately 7,700 lbs (3,493 kg). The PMC5T18 is the updated successor to the EXCEL 510, delivering faster rapids, higher spindle speed, and an upgraded control for improved productivity.
