How much does the Jainnher L100 CNC Cylindrical Roll Grinder cost?
Price estimate
We do not have a price for the Jainnher L100 CNC Cylindrical Roll Grinder 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 L100 is the larger of the two L-class CNC cylindrical roll grinding machines, with a swing over the table and a maximum ground diameter of 1,000 mm (39.4 in). Weight capacity is 6,000 kg (13,228 lb), which it shares with the L85.
That pairing tells you what the L100 is for. A roll of full diameter and length would pass the weight limit long before it filled the swing, so this is a machine for large but light bodies: hollow rolls, drums, cylinders and sleeves, or short rolls of big diameter. If the rolls are solid and heavy, the H130 is the next step, at 15,000 kg (33,069 lb).
The tailstock end deserves a look on any roll grinder, since it does more than hold a center. On Jainnher's machines the wheel dressing device is mounted on the tailstock and dresses the edge and face of the wheel by program. The tailstock base is adjusted directly to align the workpiece, and an air device underneath makes it easy to slide. The quill has 80 mm (3.1 in) of stroke with an MT#6 center. A revolving tailstock with a 4-jaw chuck is an option.
At the wheel, a 30 HP (22.4 kW) motor turns a Ø910 x Ø304.8 x 75 mm wheel at 300 to 1,200 rpm. Cross feed is 0.001 mm per pulse up to 2,000 mm/min. As with the L85, the table's centre-distance row cannot be read reliably for this type, so confirm bed lengths with the maker.

Frequently Asked Questions
01
Diameters from 20 to 1,000 mm (0.8 to 39.4 in), with a 1,000 mm (39.4 in) swing over the table, and a workpiece weight of up to 6,000 kg (13,228 lb). The centers are MT#6 and the work head turns at 6 to 60 rpm.
02
Jainnher prints one weight, 6,000 kg (13,228 lb), across both L columns, along with the same wheel, motors and coolant system. Only the swing and grinding diameter differ, so the L100 adds room for larger diameters and no extra load capacity.
03
Jainnher mounts the wheel dressing device on the tailstock, where it dresses the edge and the face of the wheel by program. A dresser is among the standard accessories. Balancing is by a static balance device and arbor as standard, with a portable balancer or auto balancing system optional.
04
When the rolls are heavy. The H130 carries 15,000 kg (33,069 lb), swings 1,300 mm (51.2 in), has a powered tailstock and supports the roll on its necks. The H130 coolant system is 2,000 L and its wheel motor is printed as 50 HP (40HPx6P).
