Global giant West Pharmaceutical Services is a pharmaceutical technology company with headquarters in Lionville, Pennsylvania. It has had a presence in Cornwall since 1968 and now has facilities at St. Austell and Bodmin, where it manufactures and supplies medical devices and pharmaceutical systems for the medical industry worldwide. As part of a worldwide group, West Pharma’s client list is also global. Their success can be measured by the fact that each day, around the world, more than 74 million West Pharma products are consumed.
The company is part way through a £2.5 million investment strategy. In the last 18 months their Bodmin machining site has doubled in size and they’ve taken on another 16 personnel. West Pharma’s impressive stable of Haas machines has been joined by yet another VF-8 vertical machining centre. The new machine will be cutting moulds from stainless steel.
“Our machines work 24 hours a day, so they must be reliable,” explains plant manager Paul Dunn. “The mould plates have anything from 500 to 10,000 cavities in them so the machine has to be quick and accurate. The Haas VF-8s have been perfect for us; they’re half the price of anything else out there and do the job without any issues. We look after our machines, we do our own daily and weekly checks and we have a Haas service contract.”
The Haas VF-8 vertical machining centre has 1626 x 1016 x 762 mm xyz travels and is built using all American-made cast-iron components. Customer feedback coupled with the relentless pursuit of perfection sees advancements and design-enhancing changes incorporated directly into the production line every day. The Haas VF-8 is a rugged VMC that yields full reliability and accuracy in a large-framed machine.
The VF-8 has a 40-taper cartridge spindle powered by a 20 hp vector Dual-Drive. The VF-8 produces either 75 ft-lb of torque at a low 1400 rpm, or 250 ft-lb at 450 rpm with the optional 2-speed gearbox and will also run up to 7500 rpm in 1.2 seconds for finishing aluminium.
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.
