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?
