How much does the You Ji YH28 cost?
Price estimate
We do not have a price for the You Ji YH28 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
The You Ji YH28 is a 10 in (254 mm) chuck CNC horizontal turning lathe offered in two bed lengths. The catalogue gives the maximum turning length as 550/1,050 mm (21.7/41.3 in), so the same headstock and turret serve either a chucker or a short-shaft machine.
The spindle is the strong point. An A2-8 nose passes Ø74 mm (2.9 in) bar, and the motor is 18.5/22 kW (24.8/29.5 hp) across a 1-3,000 rpm range. Next to the YH21, with its 9/11 kW (12.1/14.8 hp) motor, the YH28 is clearly the roughing machine of the two even though the turning diameters are close: Ø430 mm (16.9 in) here, inside a Ø680 mm (26.8 in) swing.
That gap between swing and turning diameter is larger than usual and worth understanding. Swing is what clears the bed and covers; turning diameter is what the turret can reach. A part can therefore be loaded that is too large to be turned on its full outside diameter.
Bed length changes the footprint. Machine length is listed as 3,793-4,180 mm (149.3-164.6 in) and width as 1,750-1,940 mm (68.9-76.4 in), with a height of 2,010 mm (79.1 in). The turret is a 10-st. unit and the YH key lists a C-axis function for this size. Hydraulic cylinder rods, flanged shafts, couplings and pipe fittings from Ø74 mm (2.9 in) bar are typical work.

Frequently Asked Questions
01
The catalogue lists 550/1,050 mm (21.7/41.3 in). Machine length is correspondingly 3,793-4,180 mm (149.3-164.6 in) and width 1,750-1,940 mm (68.9-76.4 in).
02
A2-8 spindle nose, 10 in (254 mm) chuck, Ø74 mm (2.9 in) bar capacity, 18.5/22 kW (24.8/29.5 hp) motor and a speed range of 1-3,000 rpm.
03
The table lists a Ø680 mm (26.8 in) swing and a Ø430 mm (16.9 in) maximum turning diameter. Swing is the largest part that clears the machine; turning diameter is the largest the tools can cut. Check both against the part drawing.
04
The YH36 has a 15 in (381 mm) chuck, an A2-11 nose, Ø89 mm (3.5 in) bar capacity and a 37/45 kW (49.6/60.3 hp) motor, and it turns Ø600 mm (23.6 in).
