3. 1. About Henfux
Henfux was founded in mid 1990s as a grinding accessories shop,
with 20 years rapid development, Henfux now becomes a group
company headquartered in Shenzhen city, with subsidiaries covering
mainland China, Taiwan, and Hongkong. The group has totally 9
subsidiaries, they belong to 8 Business Units(BU): Centerless Grinding
Machine BU, Cylindrical Grinding Machine BU,High Speed Tapping &
Drilling Center BU, CNC Machine Center BU, CNC Lathe BU, Machining
BU, Sheet Metal BU, Casting Production BU, each BU focuses on the
specific product’s R&D and Production.
Henfux introduces international leading manufacture technology,
continuously invests on self research & Development, together with
top class equipment and rich experience on machine manufacture,

4. now Henfux has various patented products in Machine Center,
Tapping & Drilling Center, Lathe, and Centerless Grinding Machine,
the high end machines of Henfux already reach international first
class level.
Keeping Focusing & Investment on R&D, Marketing, and Service, this
is the key factor to help Henfux achieve fast and stable development
in the past years. The School-Enterprise Cooperation program builds
up talent pool for Henfux, through this program, students can get
training in production line, Henfux technical experts also give lectures

2. Henfux Centerless Grinding Machine BU
Centerless Grinding Machine BU is one of Henfux Business Units, also
the oldest product lines of Henfux, in 2003, Henfux introduced
Technology from Taiwan to set up the centerless grinder product line
in mainland China, currently we produce 3 types centerless grinder:
Hydrodynamic centerless grinder, Hydrostatic centerless grinder, CNC
centerless grinder.
Hydrodynamic centerless grinder is the economy type machine
which is widely used in grinding works, currently, most of the
centerless grinder makers are producing this kind of machine.
Hydrostatic centerless grinder is the high end machine which is made
with Henfux patent technology—Hydrostatic spindle.
Hydrostatic spindle bearing arrangement can provide advanced

6. spindle technology with following benefits:
A. Technical advantage
-High rigidity even during heavier than normal loading and low
eccentricity.
-High pressure flow of spindle oil reduces spindle heating.
-A film of high pressure oil between the spindle and spindle bearing
ensures there is zero direct metal to metal contact.
B. The Stiffness of the spindle:
Henfux designed stiffness of our Hydrostatic spindle is 25kg/cm2,
hydrostatic is a complete formed and doesn`t mean just the SPIDNLE
but also the housing and oil loop. The spindle stiffness of Hydrostatic
spindle is 4 times higher than the Hydrodynamic spindle stiffness.
This will help in sustaining the high precision for a longer period of
time.
C. Frequency resonant:
This is an overall measure of machine rigidity measure. The higher
parameters enabled to removal higher rate material removal.
Generally in standard, the Frequency resonant of Hydrostatic spindle
type bearing & housing attributes nearly 500Hz v/s 80 Hz for the
conventional spindle design
D. The ultimate gain between Hydrostatic spindle and
Hydrodynamic spindle.
-At least 20 to 30 % higher productivity compared to Hydrodynamic
type arrangement and Hydrostatic type can given more advantage for
GW.
-At least 15 ~20 % Higher accuracy compared to Hydrodynamic type
spindle.
E. Henfux offers 3 years Warranty for Hydrostatic spindle bearing
arrangement.
CNC centerless grinder is the main flow of current manufacturing
requirement, more faster, more efficiency, more precision are the
common requirement of high-end manufacture. Henfux has one
experienced R&D team to design CNC machine according to
customer’s requirement.
Featured with auto loading/unloading, auto dressing, auto infeed,
auto compensation, Henfux CNC centerless grinder can match
customer’s complex and big batch production.
