Universal Cylindrical Grinding Machine for External, Internal and
Taper Surface Grinding
Product Overview
The Universal Cylindrical Grinding Machine is a practical and reliable grinding solution designed for
external cylindrical grinding, internal hole grinding, taper
surface grinding, small shaft grinding, round sleeve grinding,
needle valve grinding, plunger grinding, and precision metal part
finishing. With flexible clamping methods, hydraulic and manual
worktable movement, rotatable grinding wheel frame, rotatable
headstock, and inner hole grinding capability, this machine
provides strong versatility for precision machining workshops.
This universal cylindrical grinder is mainly used for grinding the
cylindrical surfaces and conical surfaces of small shafts, round
sleeves, needle valves, plungers, and other precision cylindrical
components. It can also perform internal hole grinding, making it
suitable for workpieces requiring both external and internal
surface finishing.
The machine supports multiple tooling and clamping methods,
including center support, three-jaw chuck clamping, spring collet
clamping, and special fixture clamping. This flexible setup allows
operators to process different workpiece shapes, sizes, and
grinding requirements more conveniently.
The longitudinal movement of the worktable can be operated
hydraulically or manually. Hydraulic movement supports stable and
efficient grinding feed, while manual movement provides convenient
adjustment for setup, inspection, and small-batch production. Both
the grinding wheel frame and the headstock can be rotated, allowing
the machine to grind cylindrical surfaces, taper surfaces, and
special angled surfaces.

Frequently Asked Questions
What is a Universal Cylindrical Grinding Machine used for?
It is mainly used for external cylindrical grinding, internal hole
grinding, conical surface grinding, small shaft grinding, sleeve
grinding, needle valve grinding, plunger grinding, and precision
metal part finishing.
What is the difference between a universal cylindrical grinder and
a standard cylindrical grinder?
A universal cylindrical grinder offers more flexible grinding
capability. The grinding wheel frame and headstock can rotate, and
the machine can support external grinding, taper grinding, and
internal hole grinding.
What workpiece clamping methods does this machine support?
The machine supports center support, three-jaw chuck clamping,
spring collet clamping, and special fixture clamping according to
different workpiece shapes and processing requirements.
Can this machine grind tapered surfaces?
Yes. Both the grinding wheel frame and the headstock can be
rotated, making the machine suitable for conical and taper surface
grinding.
Does this machine support internal grinding?
Yes. The machine has the function of grinding inner holes, allowing
it to process workpieces that require internal surface finishing.
How does the worktable move?
The longitudinal movement of the worktable can be operated
hydraulically or manually. Hydraulic movement supports stable
grinding feed, while manual movement is convenient for setup and
adjustment.
What information is needed for quotation?
Please provide workpiece type, material, diameter, length, external
or internal grinding requirement, taper angle if needed, required
accuracy, surface finish requirement, production quantity, and
preferred machine configuration.
