Honor Seiki PL-200CM

In the middle of Honor Seiki's Y-axis range, the PL-200CM turns 2,500 mm (98.4 in) in diameter and 1,600 mm (62.9 in) in height with a 12,000 kg (26,455 lb) workpiece limit. It is the only PL model that is taller in the cut than its VL counterpart: the VL-200CM, with the same diameter and load, is listed at 1,480 mm (58.2 in).

The smallest PL goes the other way. The PL-160CM has 1,000 mm (39.3 in) of turning height, well under the VL machine of its size. So within the PL series the 200 is the model for work that is both wide and tall, such as large valve bodies, compressor casings and gearbox housings that need turned bores on the axis and milled pads, ports and bolt faces off it.

The machining concept is stated by the maker in a line: a high rigidity vertical lathe combined with a gantry-type Y-axis mechanism, capable of operations similar to a bridge type machining center. A head that moves in Y over the table can mill a straight keyway or a rectangular flange face without interpolating the rotary table, and can drill a rectangular hole pattern directly.

Be careful with two rows of the published table. Tool positions read R16+L60 with no explanation. And the row labelled live spindle speed holds values that fall with table size across the three PL models, which is how a table speed behaves, so it is left out here. The milling spindle's speed, power and taper should be requested.

A lubricant chiller for the spindle bearing and gear, a cabinet air conditioner and a coolant bed shower system are standard. A tool presetter inside the machine, linear encoders and a Siemens controller are options.
