How much does the YCM DCV4021B cost?
Price estimate
We do not have a price for the YCM DCV4021B that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
Twenty tonnes is the table rating of the YCM DCV4021B, a double-column machining center with 4,065 mm of X travel and 2,100 mm of Y. The table is 4,100 x 2,000 mm and the machine itself weighs 46,000 kg.
The figure deserves a moment. A fully loaded table and its workpiece can weigh as much as a smaller bridge mill, and all of it has to start, stop and reverse on the X axis. YCM moves it with a direct drive gearbox instead of a ball screw alone, on roller type guideways with a large number of slider blocks. X rapid is 12 m/min, the cost of that mass; Y and Z rapid at 15 m/min.
Four metres by two suits the large tools of the car and appliance industries: stamping dies for body panels, injection molds for bumpers and dashboards, die-casting dies for structural parts. These arrive as rough castings or flame-cut blocks, and the standard spindle is geared for them, 4,500 rpm on a BBT50 taper through a 2-step transmission. The power row reads 25/25/45 kW against speeds of 4,500, 6,000 and 10,000 rpm.
The columns are 2,320 mm apart on bases widened with boots, and the Z slide has a Turcite-B lining for damping. T-slots are 28 mm on a 200 mm pitch. Z travel is 762 mm, optionally 1,016 mm. Forty tools are standard, with 60 or 120 optional, each up to 20 kg.

Frequently Asked Questions
01
20,000 kg, on a table of 4,100 x 2,000 mm with T-slots listed as 9 x 28 x 200 mm. The machine weighs 46,000 kg, so the foundation has to be designed for both.
02
X travel is 4,065 mm and Y travel 2,100 mm. Z travel is 762 mm, or 1,016 mm as an option. The distance between columns is 2,320 mm.
03
Rapid traverse is listed as 12/15/15 m/min for X, Y and Z, and cutting feed as 1~10,000 mm/min. The X axis, which carries the table and workpiece, is driven through a direct drive gearbox.
04
The DCV3021B has 3,060 mm of X travel, a 3,100 x 2,000 mm table for 15,000 kg, a 15 m/min X rapid and weighs 41,000 kg. The DCV4021B has 4,065 mm of X, a 20,000 kg rating and weighs 46,000 kg.
