So in amongst this extensive selection of specialist machine tool dealers how do we expect to find the right used lathe or used machining centre? Buying second hand machine tools is conceptually no different to buying a 2nd-hand car. You will be presented with an abundance of offers and promises [link widoczny dla zalogowanych] of quality and longevity but buyer beware - a second hand lathe or machining centre might look as good as new, but it could also have a few miles on its clock!

There are several key indicators worth taking into account when thinking of investing in a second hand machine tool; the number one metric being number of active hours. How long has the machine been in operation since new? Like a car has an odometer to tell how many miles it has travelled, machine tools have such an indicator too; this is called the hour clock and it logs every hour the machine has run. As an example, a second hand lathe or a second hand machining centre running in an automotive component manufacturer could well be subject to shift work, this would suggest that a machine is being worked 24/7. Alternatively another similar machine may have been sat in the corner of a factory and only used for 8 hours a week. Checking the hour clock will give you a great idea of exactly what type of life a machine has had. If the hours are low, that's a great start.

Secondly, always look at the materials that the machine has been cutting. Tough and hard materials such as stainless steel and tensile steels demand more power and in return can compromise machine performance in the long run. Materials such as aluminium make for light work and could be compared to a car being driven down straight roads at 40 mph for its entire life. The best way to investigate the material history is to ask the seller where the machine came from and also look under the bonnet! If you check under the slideway covers for material residue, you'll often find swarf - albeit small [link widoczny dla zalogowanych] amounts in enclosed areas.

Further aspects to consider include, has the machine had a crash at any point? This is a tough one to gauge and unless you’re prepared to contract in the services of a suitably qualified service engineer you'll find it nearly impossible to check this one out. A service engineer can quickly identify whether the machine has had an incident by running an alignment check on every axis. Again, referring to the car analogy, you wouldn't knowingly want to buy a car that had been in an accident, so use the same common-sense test of reasonableness when investing in used machinery.

Often beyond the fundamentals and the above [link widoczny dla zalogowanych] information, word of mouth is a strong source of encouragement. Discussing with fellow engineers as to the relative merits of a particular brand of lathe or machining centre will give you a good feel as to what's hot and what's not. You tend to find that there are machine tools in the market place that have gained a great reputation for resilience and reliability and equally as many machine tools that have deservedly gained a reputation for the opposite reason. It's not for us to judge but simply to advise. A popular brand/style of lathe or machining centre can often be found in multiples in machine shops and there's no better reference than finding an engineer who is running with, multiple installations of a specific machine type.

Nowadays it's not uncommon for engineers to search foreign markets for second hand lathes and second hand machining centres; this broadens the choice but can carry even greater risks. Whilst buying a machine tool from overseas may well increase the options available to you, possibly with a cost saving too, it may also leave you with little if any [link widoczny dla zalogowanych] support once the machine is delivered. There are also implications with import duties and power requirements that vary from country to country, so it's well worth recruiting the services of someone that knows this market in the event you choose to tackle it.

Throughout Europe there are thousands of machine tool dealers a lot of whom work in trading partnerships as the World becomes a smaller place with the [link widoczny dla zalogowanych] Internet providing a trading platform like no other. A lot of second hand lathes and machining centres are shipped from country to country and this rarely presents a problem. There are a lot [link widoczny dla zalogowanych] of positives to using this route [link widoczny dla zalogowanych] but it will potentially engage a lot more of [link widoczny dla zalogowanych] your time.

Compared to the 1970s and the 1980s buying [link widoczny dla zalogowanych] and selling in today's fluid global market is much easier; choice is greater, supply is greater and legislation should in most cases protect you against [link widoczny dla zalogowanych] the so called 'dodgy dealer'. However as with any high value purchase there is always a risk. Hopefully [link widoczny dla zalogowanych] by putting into practice some of the above mentioned safeguards you’ll help minimise the likelihood [link widoczny dla zalogowanych] of risk.
