Jainnher is a grinding technology leader in
the automobile and motorcycle parts in-
dustry. The company's sales territory co-
vers 40 countries, with over 55 distributi-
on locations around the world. In order to
meet various grinding demands, more
than 22 kinds of grinding machines have
been designed and developed, including
Centerless, Cylindrical, Internal, Double
Spindle (ID/OD), Center Hole, Angular
& Plunge Cylindrical, Thread and Vertical
product series. Annual capacity is around
400 machines, and manufacturing flexibi-
lity enables Jainnher to quickly respond to
customer orders.To ensure production
stability, 90% of machine critical parts are
made and processed in-house, and ISO
9001 certification ensures quality. Quality,
compliance with regulations, and custo-
mer satisfaction main priorities. Long-term
cooperation with distributors in Europe,
America and Asia allows for complete
service regardless of time
difference. Since Jainnher designed the
first traditional cylindrical machine in
1997, the company's technical team has
developed many kinds of NC and CNC
machine series to fulfill more and more
precision grinding requests in different in-
dustries. Not just in automobile and mo-
torcycle parts industries, good results ha-
ve been obtained in aerospace,
electronics, medical, precision hardware,
and commercial parts industries.The JHU
cylindrical machine series offers traditio-
nal, NC, and CNC version. The machine
base is one-piece manufactured from Me-
ehanite cast iron and tempered for maxi-
mum stability of material. Cooling and
drainage are quickly accomplished. The
maximum working swing is 350 mm, and
grinding wheel size is 405 mm. Grinding
length range is 600–2 000 mm and maxi-
mum grinding diameter is 330mm. Maxi-
mum weight of workpiece is 130 kg.
Worktable swivel angle is 90 CCW/
30 CW. The grinding wheel motor is
5HP. Machine can be equipped with in-
ternal attachments for internal taper
grinding.NC models can be equipped
with Human Machine Interface (HMI). For
technicians, the conversational operation
interface is easy to learn and makes ad-
justment convenient and easy. A CNC
model with hydraulic tailstock makes
workpiece loading / unloading simple.
There is a variety grinding cycle suitable
for angle, traverse or taper grinding. The
CNC program uses form type design to
input settings and is able to expand the fi-
eld of grinding for different workpieces.
For both mass production and small-volu-
me large-variety production, JHU machi-
nes can meet all demands.Grinding ma-
chines are a key factor for production
quality. Jainnher provides not just precisi-
on machine tools, but also automation so-
lutions. The company will continue to
advance grinding technology to deliver
a whole new experience. p
