How much does the Jainnher JHU-2715CNC cost?
Price estimate
We do not have a price for the Jainnher JHU-2715CNC 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 Jainnher JHU-2715CNC gives Jainnher's 270 mm (10.6 in) swing universal grinder a 1,500 mm (59.1 in) grinding length. It is a machine for long, fairly light shafts: grinding diameter is 250 mm (9.8 in) and the weight limit between centers is 130 kg (287 lb).
One row of the table shows where the longer bed starts to ask more of the drives. Jainnher lists two servo motors, labelled X and Y. The X servo is 1.2 kW (1.6 hp) on every model. The second is 1.8 kW (2.4 hp) on the JHU-2710CNC and 2.5 kW (3.4 hp) here, which fits a longer and heavier table being moved. The maker's label for that axis is Y, where most grinder builders would say Z, so check the axis naming when reading programs or manuals.
Length costs taper range. The table swivels 7° counter-clockwise and 4° clockwise on this bed. It also costs floor: the machine is about 6,400 mm (252.0 in) long, and gross weight is about 7,400 kg (16,314 lb).
A shaft a metre and a half long will deflect under the wheel unless it is supported. A 2-point center rest is standard at this length and two sizes of 3-point rest are optional. For holding size along the length, the X-axis linear scale and touch probe gauge are standard on the CNC models, and a Z-axis linear scale and an auto in-process gauge are offered as measuring options.

Strengths & Limitations
Strengths
- 1,500 mm (59.1 in) grinding length for long shafts on a 270 mm (10.6 in) swing
- Second servo motor uprated to 2.5 kW (3.4 hp) for the longer table
- 2-point center rest standard; 3-point rests in two sizes optional
- X-axis linear scale and touch probe gauge standard on the CNC models
Limitations
- Table swivel narrows to 7° counter-clockwise and 4° clockwise
- Machine length is about 6,400 mm (252.0 in)
- Weight between centers stays at 130 kg (287 lb), so long parts must be slender
- Jainnher labels the second servo axis Y, which differs from common grinder convention
