Mills CNC claims big market share for big machines

Mills CNC claims over 50 per cent of the UK's large lathe market (chuck size 12" and over), 50 per cent of the large VTL (Vertical Turning Lathe) market and significant market share in the large horizontal machining centre and horizontal borer markets.

Mills CNC claims big market share for big machinesThe company is the exclusive UK and Ireland distributor for Doosan machine tools, and highlights that the portfolio has recently been broadened with the launch of a new range of 5-face, double-column machining centres, DCM, within which there are eight different sized.

The new DCM machines, with up to 10, 250 by 4,200 by 700, by 1,100 mm in X, Y, Z and W, can parts up to 68,000 kg in weight.

Depending on the type of application, DCM machines can be specified with various ram spindle configurations (heavy-duty cutting through to high-speed/high-torque options); different head attachments and table types.

"The Doosan big machine tool range is impressive – and the new DCM machines are no exception," underlines Nick Frampton, Mills CNC's managing director.

"In terms of breadth, depth, technical specification, and all-round performance and price – big Doosan machines are the number one choice for precision manufacturers in the oil and gas, power generation and other sectors where the machining of large components is at a premium."

How to Choose a Lathe Machine


Lathe machines are machines built to serve a specific purpose and even though there's a lot of variety to choose from, you really must choose the one that suits your needs the best. The average hobbyist will likely be best off with a mini lathe, which has a limited scope of operations but can be very useful for small and personal projects. These are mainly used by beginners who are testing the waters for turning out shapes and designs.

Whilst these mini lathes are not at all suited for professional lathe projects, those who want to make a slower transition to bigger lathe machines do have options to upgrade their mini lathe machines. These upgrades add functionality like variable speeds, arms etc. This also makes sense for those who want more out of their machine without spending a lot of money for a new and bigger machine.

However, there is a limit to how much a basic lathe machine can be upgraded, so it is advisable that professionals who have discovered the power of a lathe machine upgrade to as big a lathe as they possibly can. This is meant for those craftsmen who can see a long future of them using the lathe machine. For those who are unsure of how long they will use one or those who are on a tight budget, there are mid segment lathe machines that usually have a size between 12x34 and 16x36. They cost in between $400-600 and offer enough features and sturdiness for the professional craftsman without burning a hole through his pocket.

There are a few things to consider before jumping in and buying the cheapest or the biggest machine out there for your budget. You need consider the spindle you are getting. The spindle is the core to the operations of lathe machines and they come in standard and non-standard sizes. The is usually a good idea to go for standard sizes like the 1"x8tpi spindles. The bed capacity is also important, as this will determine the size of material with which you can work. Variable speed is another aspect because most professionals prefer to work at different speeds while doing different things to the material. Like for sanding you would prefer a higher speed but for carving, you might want a medium to low speed depending on the detail you want to work in.

Be careful of cheap lathe machines because their parts are often non-standard and are hence very easy to replace. As with other power tools and hardware, buying from a reputed company is always advisable. If you are buying used machines, do not purchase without getting to check it out first. For used lathe machines, try to purchase locally from a shop you know. If you are buying over the Internet even, try to buy from somewhere nearby and pick it up yourself after checking it out properly. Again, keep in mind the purpose of your machine while making a purchase.
