5-Axis Horizontal Maching Center
Like all Dah Lih machining centers, the MCQH-400 five-axis horizontal machining center is a superbly crafted machine tool that is solidly built. The machine bed employs a forge construction technique whereby the X, Y and Z axes slideways are alloy steel and cast iron unit-forged. This upgrades hardness and provides vibration absorption and rust resistance. Ways are hardened with Turcite-B and the 3-axes ball screws are pretensioned, which increases position accuracy by reducing thermal expansion. The unit features a Fanuc 18MC control.
Featuring a double pallet indexing table, the table load on the 15.75" x 15.75" pallet is 660 pounds. Travel is 20.5 in the X, 20.1" in the Y, and 16.1" in the Z. Cutting feed is 0.04" - 472"/min and the rapid traverse feed is 1890"/ min. The automatic tool changer has a 24 tool storage capacity and a double support cam-type tool arm for a swift and smooth tool exchange. The gear driven spindle is extremely rigid and features an "OIL-AIR" lubrication system on the front and rear bearings. Spindles speed 20,000 rpm.
Five Axis Specifications
Many machine shops are discovering the advantages of five-axis machining. With five-axis machining there is a reduction in setup time and often reduced fixture and tooling costs. Machine time is reduced and product quality is somewhat better than three-axis machining. Likewise, an experienced programmer can usually take less time to program a part with five-axis than with three-axis.
