Microns Precision Engineering provides a first-class sub-contract engineering solution to customers across the UK and Europe. Founders James Campbell and Garry Mills met while working as machinists at another firm, but in 2008, with a recession looming, they began to visualise starting a company of their own. “We wanted more control.” says James, “We didn’t start with much but because of the economic downturn things were cheaper. We bought a second hand Haas mill and started to build up a customer base.”
Within a year the Cambridgeshire based company had invested in their first new Haas, a Mini Mill vertical machining centre, and were steadily building a reputation for accuracy, with a fast delivery. They soon outgrew their original premises, and after expanding into two larger units they began looking to see how they could fill their newly acquired space.
Today, nearly a decade later, Microns has installed ten Haas machines, the latest of which is a VF-2SS Super Speed mill. With customers in industries ranging from agricultural to motorsport, scientific to gas and oil, the VF-2SS needs to be adaptive. “If something can be machined; we have a customer who wants one,” explains James.
“We can use the Haas machine for everything. Right now we’re making DTS nano-positioning equipment, which is mounted to lasers and microscopes, so our parts have to be dead flat. The accuracy on the VF-2SS is incredible, and it’s undoubtedly the fastest machine we have. The tool changer is so speedy our jobs are noticeably quicker, which makes the whole process more efficient.”
The Haas VF-2SS features a 12,000 rpm, 30 hp spindle, has travels of 762 x 406 x 508 mm and rapids of 35.6 m/min. The machine’s 24+1 side-mount tool changer swaps tools in just 1.6 seconds.
“This is our second Haas with 4-axis capability and we’ve found that gives us a flexibility we hadn’t previously seen. Because the controls are the same on all of the machines we can switch from one to another in no time.”
“Our original Haas was easy to use and we were impressed with the way it dealt with everything we threw at it. We’ve come back time and again because we know we’ll always get quality. And our salesman and local engineer are both amazing; they can’t do enough for you.”
“The accuracy on the VF-2SS is incredible, and it’s undoubtedly the fastest machine we have. The tool changer is so speedy our jobs are noticeably quicker, which makes the whole process more efficient.”

For Example: When a rotary fits with alternative fixturing, it may fit in that particular Haas mill, but will require a sub-plate or alternate T-slot for proper positioning. We have labeled this particular rotary and mill combination with a yellow caution
You can design and build your own sub-plate using the dimensions of your Haas mill and the dimensions of the rotary you'd like to use on that mill. Product dimensions are available for every machine and rotary on this website.
Single-Head Rotary Tables and Indexers are usually mounted to the right side of the table, with the rotary facing the centre of the machine. This is the basic setup we used to determine the fit of your rotary product.
Image shown for mounting example purposes only. Your actual rotary and mill appearance may differ.
Trunnion Tables, T5Cs, and TRTs are usually mounted in the centre (or slightly off-centre) of the mill table. If you are using probing on the mill, be aware of the interference with larger tools, especially during tool changes.
NOTE: Trunnion units present interference issues with the swing of the unit relative to the machine column and spindle head.

Multi-Head Rotary Tables and Indexers are usually mounted toward the back of the table, with the indexer heads or platter facing forward. To mount a multi-head rotary in a different orientation, you must use alternative fixturing.

Important Information:
4-axis machines cannot use dual-axis rotaries.
Some options may affect mounting (EC-1600 4th-Axis Table, Low-Profile Tables, Table Spacers, Column Risers, etc.
Tool Changers: SMTCs and umbrella tool changers both present interference issues, plan appropriately.
