How much does the Jainnher JHA-3505CNC cost?
Price estimate
We do not have a price for the Jainnher JHA-3505CNC 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 JHA-3505CNC is a CNC angular cylindrical grinder with 350 mm (13.8 in) of swing. Its distance between centers is 600 mm (23.6 in), but the maximum grinding length is 520 mm (20.5 in). The 05 in the name reflects that shorter figure.
The lost length is the price of the angled head. A wheel that comes in at 60° occupies room along the part's axis that a square-fed wheel does not, so on the same bed the plunge-type JHP-3506CNC grinds the full 600 mm (23.6 in). Table travel is 600 mm (23.6 in) here.
In return the angular machine gets a bigger, faster and stronger wheel. It is listed as Ø610 x 50 ~ 100 x Ø203.2, a step up from the Ø510 of the plunge machine, and the maximum peripheral speed is 40 m/sec. The standard motor is 10 HP (7.5 kW), and 15 HP (11.2 kW) is optional. Grinding a diameter and a face at once puts more wheel in contact with the work, and the extra power is there to keep the cut from stalling.
The spindle runs in hydrodynamic or hydrostatic bearings, lubricated from a 50 L tank and cooled by an oil cooler that is standard at this size. Workpieces up to 150 kg (331 lb) run between No. 4 centers. Fully enclosed, the machine weighs 7,460 kg (16,446 lb).

Strengths & Limitations
Strengths
- Ø610 wheel with a maximum peripheral speed of 40 m/sec
- 10 HP (7.5 kW) wheel motor as standard and 15 HP (11.2 kW) optional
- 60° feed angle for grinding diameter and shoulder together
- Hydrodynamic or hydrostatic wheel spindle with a standard oil cooler
- Takes 150 kg (331 lb) within a 350 mm (13.8 in) swing
Limitations
- Grinding length is 520 mm (20.5 in) on a 600 mm (23.6 in) center distance
- Table travel of 600 mm (23.6 in) is shorter than the 700 mm (27.6 in) of the JHP-3506CNC
- The wheel head angle is fixed at 60°
- Printed grinding diameter is Ø330, below the swing

Frequently Asked Questions
01
Jainnher gives 600 mm (23.6 in) between centers and a maximum grinding length of 520 mm (20.5 in) without explaining the gap. On an angular grinder the wheel approaches at 60°, so part of the length near the tailstock cannot be reached by the inclined wheel head.
02
The JHA-3505CNC wheel is listed as Ø610 x 50 ~ 100 x Ø203.2 with a peripheral speed of 40 m/sec and a 10 HP (7.5 kW) motor. The JHP-3506CNC has a Ø510 x 50 ~ 100 x Ø203.2 wheel, 33 m/sec and a 7.5 HP (5.6 kW) motor. Both run at 1,250 rpm.
03
Jainnher offers hydrodynamic or hydrostatic bearings. The table lists separate pump motors for each, and a 50 L wheel head lubrication tank. A pressure switch prevents the spindle from starting until lubrication oil pressure reaches its set value.
04
7,460 kg (16,446 lb) net when fully enclosed and 6,840 kg (15,079 lb) semi enclosed. Gross weights are 7,860 kg (17,328 lb) and 7,240 kg (15,961 lb).
