Second-hand Universal Milling
Machines & CNC
All-round metalworking with universal milling machinesThe universal milling machines are named this way as they are able to
change pieces of metal into any conceivable product. One more excellent feature
of universal milling machines is that they are very customizable in that they
are able to be extended with many different types of tools.
does a universal mill comprise of?
A universal mill comprises of:
●A work table
The milling table works in synchronized
movements with the spindles to manufacture a final workpiece, these are very
diverse by manufacturer and product. On most models, the table passes along the
X and Y axis, the spindles on the other hand run on the Z axis. It is also
possible to produce two additional movements with the correct tools and machine
attachments. Top of the range universal mills the tables are able to pivot and
rotate and allow the milling head to travel around the product.
Universal milling machines come in
various versions including CNC, manual and cycle controlled.
CNC machines has been the standard for a
long time now in industrial contexts, a few smaller manufacturers still build
manual universal mills.
between the different types of milling machines
name, the universal milling machine is not appropriate for all jobs: when
dealing with exceptionally bulky and parts that weigh a lot, having the work
table move is a disadvantage and causes more problems than it solves. Thus, the
gantry milling machine was created by industry to solve this problem.
milling machines performance levels are second to none, the spindle moves
around the component via a gantry guiding system. There are also a few other
classes of milling machines that specialize in doing different tasks, such as
the knee-type and bed-type milling machines.
What would you
use universal mills for?
milling machines are usually used manufacturing single pieces, however with the
advent of CNC machines with digital controls and computing technology means
that re-production of a single part or product is easily produced again and
again as the product is stored within the memory of the computer.
industries have produced a range of milling machines that are used for uniform
reproduction, however if you are trying to create smaller batches, to train
employees or produce prototypes then basic universal milling machines are what
you are after. These types of milling machines are will often be seen in repair
workshops all over the world.
Add-ons for the Universal Mill
machines should, without fail be equipped with cooling lubrication. This
lessens the damage and wear to milling tools and parts whilst simultaneously
keeping up high standards or quality.
housing and partition walls are an option to keeping your environment in and
around the workstation clear, both these options are extremely advantageous.
Lighting the milling machine and work area also needs to be taken into
a longer time period can also be maintained through compatibility from the
recording of workpieces that have been created.
Things prospective buyers would like to know before
they buy a Universal Milling Machine?
a universal milling machines, many factors have to be thought about before
purchase, the machines come in many different sizes, processing options and
As the name suggests, the universal milling machines
have the option of having a great scope in the varied tools that can be used
with them, however not all products can be made on every milling table with
precision and in a high quality manner.
some questions to answer when buying the correct machine:
●What is the size of the product that will be produced?
●Are regular re-productions needed or a series of the same product over and over?
●What are the tolerances levels that are needed within the product?
big workpieces that are either have a lot of weight to them, very hard
materials or precision products, the better the standard of machine design will
need to be purchased. More basic milling machines are still excellent at
producing items such as fittings or prototypes.
Should you want
to create pieces in series from solid steel that need to be very precise whilst
also being very resilient then you will need a milling machine that is fit for
purpose and of good quality.
If the intent is to produce quality products then the minimum requirements
●SK 30 or SK 40 tool holder
●A good quality brand should be selected that has a good reputation for building milling machines
●250 x 700 mm² of clamping surface
●A speed of 50 rpm in the slowest mode to allow threaded holes to be machined
●3000 rpm for contours
By following these attributes, an excellent product can be produced from
the softer metals: Copper, aluminum, bronze and possibly steel.
Milling accessories that are on the market should be looked at before
buying, items such as machine vices, box cubes, dividers and other tools
including other peripheral items.
These tools and accessories can run to more than the cost of the
machine, so be sure to do some research on what you will need to create your
product before purchasing the machine.
Purchasing a second-hand Universal Milling Machine
Be sure to look and possibly test a used milling machine when you are looking
at purchasing one or more. Remember to check the guide mechanisms on the
machine to check that they remain in place and solid.
If the machine is experiencing electrical problems then it is quite an
easy fix to get the machine working again.
Checking that the tracks are able to be spun manually, freely and will
little resistance from the hand wheel. Old, used or worn-out bearings could be
By the nature of how the machines work, dents, dings and scratches are
natural on a second-hand milling machine. A top tip would be that if a used
machine has a new coat of paint on it, you should be slightly suspicious about
what is hiding beneath the paint.
Of course the machine might have been faithfully restored to its former
glory but it maybe that the paint is hiding a multitude of problems beneath.
If you can run a test on the milling machine you are thinking of buying
then you should. Also remember to measure with a micrometer screw to make sure
that you are buying a machine that will be capable of reaching your workmanship
goals in relation to the quality
of your product.
In an ideal scenario, buyers should perform
a test run on a prospective second-hand machine with a sample
piece and then measure it using a micrometer screw to ensure the machine is
capable of attaining the quality desired.
How to operate a milling machine safely?
operators are still needed, even though most of the milling functions are now
automated. Making adjustments and setting the machine up are roles the operator
must take. Other requirements are fixing and releasing products, choosing the
right cutting tools and mounting said tools etc,
skills and experience working with computers are also needed by the operators
so that they can read designs and program the CNC machines to produce the
must also know safety and operating documentation of the machines whilst also
wearing the correct PPE and safety wear for the job. Operators must wear safety
glasses whilst operating the machines.
