Second-hand Grinding Machines
What is a Grinding Machine, and how
does it work?
Grinding machines produce
flat, cylindrical, and other surfaces through high-speed rotating abrasive
wheels. Grinding gives a more accurate finish to a part already machined but is
also a machining process. These are machines for shaping,
sharpening or smoothing. Grinding machines have a long history, from machines
that had to be operated manually to the high-tech machines used today such as
conventional or CNC grinding machines.
These machines are used in a broad range
Generally, grinding wheels and grinding belts reach
higher levels of accuracy than machining with geometrically undefined cutting
edges. For this reason, tool grinding machines, circular grinders, surface
grinders, bench grinders, etc., are essential for many production stages for industry
What do I need to know to operate
a Grinding Machine safely?
essential follow the safety guidance when using grinding machines to avoid
Always wear goggles when the machine is in operation.
- Do not cut below the recommended depth of the machine or wheel.
- Always remove the workpiece from the grinding wheel before switching the machine off.
- Ensure that machine guards are in good working condition and in the right place.
- You should always inspect grinding wheels for cracks before mounting.
- Do not use grinding wheels beyond the recommended limit.
- Do not make adjustments to the workpiece or mounting device when in use.
- Ensure the correct wheel guard is used for each operation.
- Ensure the tool rest is held at the set limit from the wheel.
Types of Grinding Machines
Industrial Grinders and CNC grinders come in a wide
range of varieties. They are used for
various metalwork processes. Following are some examples of the most commonly
used grinding machines.
Centerless Grinding Machines
Centerless grinding uses abrasive cutting as
part of the machine process, this takes material off the workpiece. Centerless grinding is different from
centered grinding because it doesn’t use a fixture of spindle when finding the
The workpiece is held between
two rotary grinding wheels. Material is
taken off the workpiece at a pace related to how quickly they rotate.
With Cylindrical Grinders, the
surfaces are machined in a circular motion and rotate around a fixed axis. It
results in the surface being tapered, contoured or straight.
Bore Grinding Machines
Bore Grinding Machines are used to create holes
in various materials such as stone, wood and metal. These particular machines are generally
manufactured for individual users and are offered by lower end companies.
such as Farman and Schanbacher are examples for industrial use.
Surface Grinders (with a horizontal or
you need a precisely flat surface, then the Surface Grinder is what you need. The
grinding disc moves consistently to flatten the workpiece. The mould
construction and tool building industries are key users of these products due
to their ability to deliver precise pieces.
such as Blohm and Jung produce Surface Grinders.
Guideway Grinding Machines
Grinding Machines are used where extremely large cutting machines are
manufactured for grinding guideways. They need to be accurate and the modern
machines can produce extremely high tolerances and levels of accuracy.
The machines use stones for grinding, which result in
force that delivers consistency in the outcomes.
such as SHW and Kraft produce Guideway Grinding Machines.
Double-Disc Grinding Machines
machines are really effective grinders. With these grinders, the workpiece can be ground on both sides
such as Koyo and Disjus produce Double-Disc Grinding Machines.
Bench Grinders (one- and two-sided)
grinders like the Bench Grinder, is a standard piece of kit found in most
workplaces. It’s used include deburring, planning, sharpening and grinding, and
this is carried out by hand. Each has a motor, and one or two discs can be
such as Makita and Rema produce Bench Grinders.
Stylus Grinding Machines
When grinding marking tools, stylus machines are what
you need. Stylus grinding machines also have the main function of sharpening
Manufacturers such as Parpas and Deckel produce Stylus
Crock Grinding Machines
grinding pots (known as ‘crocks’ in the USA) you need a crock grinding
machine. The pivoting arm is used to
secure the drive and guiding mechanism and they are commonly used for grinding
and altering the measurements on workpieces that are small in size, and hand
operated. The pot name is based on the
tool making a ‘pot-shaped’ movement.
such as Delta and Edel produce Crock Grinding Machines.
Roll Grinding Machines
For precision grinding of press rollers then a roll
grinding machine can achive the exact measurements needed. The machines produce
the exact tolerance using freshly turned, new and used rollers. They are the
only machine that can produce precision rollers.
Manufacturers such as Herkules and Zimmerman produce
Roll Grinding Machines.
What do I need to know when buying a Used
There are so many variations of grinders that
understanding what uses you need it to perform is the key to narrowing down
your decision. Each offers a different range of grinding options and decisions
should be based initially around that.
