We do not have a price for the Jainnher JHP-2003CNC 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 JHP-2003CNC is the smallest of Jainnher's CNC plunge cylindrical grinders: 200 mm (7.9 in) of swing, 300 mm (11.8 in) between centers and a workpiece limit of 80 kg (176 lb). It is a machine for small shafts, pins and spools ground in volume.

A plunge grinder feeds a straight wheel square into the work, and the table gives the feed angle as 90°. The wheel is Ø355 or Ø405 and runs at 1,780 rpm from a 5 HP (3.7 kW) motor, with 7.5 HP (5.6 kW) optional. Wheel head travel is 220 mm (8.7 in) and the minimum setting unit is 0.0001 mm, backed by an X-axis linear scale that is standard equipment.

Small machines earn their keep on cycle time. The table rapids at 8 m/min (315 ipm) over 640 mm (25.2 in) of travel, and the wheel head at 6 m/min (236 ipm). A touch probe gauge on the standard list finds the shoulder position before grinding, and the hydraulic tailstock is worked by a foot pedal, so loading is quick.

The 2003 size is built more simply than the larger JHP models. Jainnher's table leaves the hydrostatic wheel head rows blank for it, and the oil cooler and the tailstock dressing device are standard only on the bigger machines. Centers are No. 3, with a 48 mm (1.9 in) tailstock sleeve. Fully enclosed, the machine weighs 3,800 kg (8,377 lb); semi enclosed, 3,600 kg (7,937 lb).

Frequently Asked Questions

01 How big a part fits the JHP-2003CNC?

Maximum work swing and maximum grinding diameter are both 200 mm (7.9 in). The distance between centers and the maximum grinding length are 300 mm (11.8 in), and the maximum job weight is 80 kg (176 lb). The work head turns at 10 to 500 rpm.

02 What is left off the JHP-2003CNC compared with the larger plunge grinders?

Jainnher's accessory list marks the oil cooler, the tailstock dressing device and the wheel lifting tool as not applying to the 2003 series. The table also leaves the hydrostatic pressure, wheel head pump and wheel head lubrication rows blank for this size, and the centers are No. 3 instead of No. 4.

03 What wheel does it run?

The table gives the wheel as Ø355 or Ø405, at 1,780 rpm, with a maximum peripheral speed of 33 m/sec. The spindle motor is 5 HP (3.7 kW), 4P, with 7.5 HP (5.6 kW) available as an option.

04 Is the JHP-2003CNC fully enclosed?

It is offered both ways. Fully enclosed it weighs 3,800 kg (8,377 lb) net and 4,100 kg (9,039 lb) gross. Semi enclosed it weighs 3,600 kg (7,937 lb) net and 3,900 kg (8,598 lb) gross. A fully enclosed splash guard with oil mist device is on the standard accessory list.
