Roll tooling firm opts for VTL from Mills

Mills CNC has supplied Bowers & Jones, a specialist in high-precision roll tooling and equipment for steel and copper mill customers across the world, with a new DN Solutions VTR 1216F: a large-capacity, wide-column, ram-type vertical turning lathe (VTL). The new machine operates at the company’s 1394m² manufacturing facility in Bilston, near Wolverhampton. It sits alongside three other machines supplied by Mills CNC over the past four years, including a Doosan Puma 5100B lathe and a DN Solutions GT 3100L box-guideway lathe.

Says Jane Sommerville, managing director at Bowers & Jones: “We needed a new large-capacity vertical lathe specifically to machine large-diameter straightening rings for the customer. It would also take pressure off an older Berry & Binns horizontal lathe that we acquired some years earlier. We approached Mills and two other suppliers to discuss our requirements and, looking at the proposed investment package as a whole – including cost, availability, machine design and configuration, operator familiarity, and aftersales support – decided to place the order with Mills.”

The FANUC-controlled 50-inch chuck VTR 1216F offers a maximum turning diameter of 1600 mm and a maximum turning height of 950 mm. Equipped with a thermally-stable 45 kW/400 rpm/20,557 Nm spindle, a servo-driven 12-tool ATC and an quad tool holder with fast indexing that enables the use of four tools directly via the ram, Mills CNC says the VTR 1216F delivers fast processing speeds, improved machining flexibility and high accuracy.

Bowers & Jones machines straightening rings on its VTR 1216F from D2, a high-carbon, high-chromium molybdenum-vanadium alloy tool steel that is highly abrasive. Machining takes place from solid round bar (cut to size) in relatively small batches.

Robust lathe enables stainless steel broaching

Architectural ironmongery manufacturer Instinct Hardware has spent more than £500,000 in the past two years on a manufacturing execution system, a powder coating plant, a waterjet cutter and an Italian-built Biglia bar-fed, twin-spindle lathe with a ±45 mm Yaxis and 15 driven tools.It is the sixth CNC lathe and by far the most capable to arrive at the 68,000 sq ft factory in Stirchley, Birmingham.

The latest turning centre was sourced from Biglia’s sole UK agent Whitehouse Machine Tools. Whitehouse supplied the machine as a turnkey package with Hydrafeed short bar magazine for feeding 1.5-m long stock up to 80 mm in diameter, and a gantry-type system for unloading components onto a conveyor.

“We bought the turning centre specifically because it’s able to broach a square hole into our stainless steel handles, which Whitehouse demonstrated to us before we committed to the machine,” says director Nil Chohan.“We can now perform all operations in one hit, rather than in five or six operations using our previous production route.”

A case in point is the machining of a component assembled into a stainless steel, oval-profile, mitred lever handle. It previously required six machining operations, consuming a total of 15 minutes machining time plus 10 minutes or more handling and setup for each of the five additional operations – amounting to more than one hour overall. On the Biglia, the part comes off complete in 8.5 minutes, representing an eight-fold time saving, with the added benefit of eliminating work-in-progress and the potential for component damage.

Double acquisition for Helix Tool Company

Helix Tool Company, which was recently backed by NVM, has completed a double
acquisition as it seeks to consolidate the industrial cutting tool distribution market. In
undisclosed transactions, the Leeds-based business has acquired Floyd Automatic Tooling
and Nsert. These purchases are complementary and have been completed in line with
Helix’s organic and M&A led strategy. Following these transactions, Helix remains acquisitive
with adequate funding available to enable further consolidation across the market focussing
on technical-led tooling distributors in the UK.

Entry-level robot automates machine tending

Dutch firm Halter CNC Automation has introduced an entry-level machine tending cell for
loading and unloading. Availability in Great Britain is through sole agent 1st Machine Tool
Accessories.
Comprising a six-axis industrial robot, the Basic Pro offers a price-competitive automation
solution. With the manufacturer’s user-friendly touchscreen SmartControl, the changeover
time to start a new production process is only a few minutes. Furthermore, the operator
needs no prior experience of robot programming, which takes place while machining of the
previous parts is in progress.
The plug-and-play Halter Basic Pro can be supplied with new machines or retrofitted to
existing plant regardless of machine age and control type. Use of a floor-level, 270° laser
scanner provides a safety zone. The robot slows if the operator approaches and stops
immediately upon breaching the light curtain.
An adjustable air pressure supply is provided for the double gripper, which can have either
two or three fingers for holding raw material and finish-machined workpieces internally or
externally. It is possible to handle workpieces from 10 to 135 mm diameter or square up to
a maximum weight of 12 kg, including the gripper head. The grid plate holding the raw
material and finished parts is adjustable in height to suit the installation and can hold up to
188 workpieces if the locations are sized up to 20 mm, the number dropping to 14 parts as
the size reaches 135 mm.
Halter has more than 1000 installations worldwide feeding CNC lathes, machining centres,
deep-hole drilling machines, grinders and other machine tools, as well as CMMs. Nearly 95%
of customers across 25 countries, including two dozen or so in the UK, report a return on
investment within 5 to 18 months.

Green energy powers XYZ lathe purchase

Fletcher Moorland, a Stoke-based company that repairs and refurbishes motors, pumps,
gearboxes and fans, has purchased an XYZ RLX 780 flat-bed CNC lathe with ProtoTRAK RLX
control as part of efforts to expand services for its growing customer base.
Says third-generation managing director Matt Fletcher: “We traditionally worked on sub 1
MW motors but, with advances in wind turbines, we’re now seeing repairs required on
equipment up to 2.5 MW. These machines, which weigh around 10 tons, have bigger rotors
and end shields, and we didn’t have a machine to process these larger parts.”
The process of acquiring a large-capacity lathe involved researching the market, which
culminated in two visits to XYZ’s Midlands Technical Centre in Nuneaton.

Electrical-mechanical workshop Manager Matt Sparkes says: “Demonstrations from XYZ’s
area sales manager gave us the confidence that the RLX 780 was the right fit in terms of
machine size and capacity. After seeing the ProtoTRAK RLX control, used both manually and
in CNC modes, we knew it was the best solution for our workshop.”
With shafts and rotors increasing in size, Fletcher Moorland is already benefiting from the
purchase of the XYZ RLX 780.
“Its 160 mm diameter spindle bore is advantageous, especially when we recently machined
a batch of conveyor rollers,” explains Sparkes. “The additional fixed steady we purchased is
also proving its worth.”
In a closing remark, Sparkes says: “We really feel that the ProtoTRAK control is the way
forward. Its ease of use and flexibility aligns with our processes, and we see it enabling us to
produce one-offs quickly and efficiently using the conversational format that the control
provides.”
