Longevity of lathes prompts repeat purchases

It is often said that a subcontractor does not know what type of work will be coming through the door tomorrow, so needs versatile machine tools to produce a wide variety of components. With this thought in mind, the mainstay for production of a large proportion of turned parts at contract machinist Repro Engineering are CNC turning centres from Citizen Machinery, both Miyano fixed-head lathes and Cincom sliding-head models.

The first Miyano to arrive (in 1997) was a BND42S twin-spindle lathe with live tooling. It departed just three years ago after 23 years of service, having produced more than 2 million components, most in one hit and a large proportion in lights-out operation. The second Miyano, a BND51S, arrived in 1998 and was sold in mid-2022 after an even longer period on the shop floor.

Repro Engineering’s owner and managing director Richard Palmer says: “We have a policy of regularly reviewing our capacity and keeping plant up to date. In the case of the Miyanos, however, earlier exchange simply wasn’t necessary, as the machines continued to hold tolerance.”

The replacement for the BND51S was a more capable BNJ-51SY, which arrived in May 2022. Featuring two turrets and Y-axis movement of the main turret, the lathe facilitates complex machining operations at the main and sub spindles simultaneously. Nine Miyano machines have been purchased over the years.

Regarding Repro Engineering’s sliding-head capacity, the subcontractor operates three Cincom lathes capable of machining parts up to 32 mm diameter bar. Impressed with the quality and longevity of the Miyano machines, Palmer decided to approach Citizen for larger Swiss-type lathes capable of producing bigger diameter, often shaft-type components. He purchased a Cincom A32-VII in 2009, followed by a more highly specified M32-VIII with a B-axis in 2013, and another A32-VII two years later.

Turning up productivity with lathes from Dugard

Companies with the heritage of AW Engineering are very rare. Founded in 1908 by Alfred Wood, the subcontractor switched its workload to munitions and aircraft parts during World War II and, ever since, the company has remained under the stewardship of the same family.

In 2020, AW Engineering moved to a new 15,000sqft factory in West Molesey, since when the companyhas doubled its turnover under the leadership of Mark Felstead, the great, great grandson of company founder Alfred. Contributing to this growth is the investment in three machine tools and a robot from Dugard: two SMEC SL2000BSY twin-spindle, single-turret turning centres; a Hanwha HCR5 collaborative robot (cobot); and a Hanwha XD38 IIRNHY sliding-head turning centre.

“During the pandemic, suitable machine tool supply was sparse,” says Felstead.“We spoke with Dugard and, within two weeks of placing an order for a SMEC SL2000BSY, the machine was on our shop floor and running. With furlough and other restrictions during the pandemic, Dugard was the only company that could serve our needs. Set-ups and programming are at least 20% faster with the Siemens control and we can prepare jobs and programs with confidence using the conversational programming and simulation within the system.”

Less than six months after the installation of the first machine, AW Engineering placed an order for a second SMEC SL2000BSY. A single operator mans the two SMEC machines. However, some components in the family of parts are above the 65mm diameter bar feed threshold and require manual loading. Here, AW Engineering has purchased a Hanwha HCR5 cobot from Dugard.

“Our cobot cell is now up and running, which means that both SMEC machines can run unmanned 24/7,” concludes Felstead.

30 YEARS OF CONTINUOUS IMPROVEMENT, STRATEGIC INVESTMNET AND HARD WORK LEADS TO UNRIVALLED SUCCESS

Precision subcontract specialist, G-Mach Engineering, a company committed to continuous improvement and providing customers with best-in-class, high-quality machining services, continues its long-standing relationship with Mills CNC by investing in another high-performance machine.

Mills CNC, which is the exclusive distributor of DN Solutions (formerly Doosan) and Zayer machine tools in the UK and Ireland, has recently supplied G-Mach Engineering, which celebrates its 30-year anniversary in June this year, with a new Doosan, FANUC-controlled, multi-tasking turning centre. The compact, 8” chuck/65mm bar capacity long-bed Lynx 2100LMB lathe with integrated driven tooling, arrived at the company’s 10,000sq ft production facility in Melton Mowbray in late 2022.

As a point of note, the new Lynx lathe is the latest addition to G-Mach’s impressive in-house machining resource which currently comprises 22 CNC machines in total (eight machining centres and 14 lathes), 17 of which are Doosan machines supplied by Mills CNC.

Since being installed, the new Lynx lathe has been put through its paces machining high-precision, complex components for the company’s growing range of customers operating in the motorsport, medical and aerospace sectors, to name but a few.These components, often with short cycle times (typically around 3 minutes), are made from a range of materials that include 316 stainless steel, titanium 4 and 5, Hastelloy, Inconel, aluminium and steel. The machining of parts takes place in relatively small batches (up to 2000-off), to tightgeometric tolerances of around 0.01 mmand stringent surface finishes down to Ra 0.8µm.

The 6000rpm driven tooling capability on the Lynx 2100LMB enables G-Mach to turn, mill, drill and tap small parts to completion in one set-up, improving the company’s productivity and process efficiencies, and enabling it to improve throughput and reduce production bottlenecks and pinch points.

G-Mach is a keen advocate and proponent of multi-tasking machine tools and, way back in 2000 when the company first started its relationship with Mills CNC, invested in its first multi-tasking machine: a Puma 230MSB sub-spindle lathe with driven tooling.

Says Graham Miller, G-Mach’s owner and director: “We’re an innovative and progressive company and, to differentiate ourselves in the market and maintain our competitive edge, we’ve always invested in advanced machine tools.A majority of these have been Doosan machines supplied by Mills CNC.”

He continues: “In the past four years alone, we’ve invested in five new Doosan machines.
Doosan machines are accurate, reliable and deliver excellent cutting performance. They are backed by Mills CNC’s aftersales service and support which, we believe, is the best in the business.”

A cursory view of G-Mach’s history reveals that the company invests in at least one new machine tool every year. This commitment to continuous improvement and growth extends far beyond new machine tool acquisitions.The company is constantly expanding, re-developing and improving its facility and, in 2022 prior to the arrival of the new Lynx 2100LMB and with the help of Mills CNC, G-Mach re-organised its machining operations to create separate and discrete turning and milling ‘sections’ within its facility.The re-organisation necessitated the quick, seamless and simultaneous movement of 17 machines.

“The re-organisation, achieved with help from Mills CNC, has helped us improve workflow and achieve significant machining efficiencies,” states Miller.

Other improvements implemented by the company to help cope with growing demand for its services, include the recruitment of four additional members of staff over the past three years.The company’s current head count stands at 20.

Even during the pandemic, when many companies were postponing or scaling back their investment plans, G-Mach was on the front foot and, in March 2020, successfully acquired a small plastic-part subcontract machining specialist as a going concern.

Says Miller:“The acquisition has helped us to diversify our operations further and, during the height of the pandemic, provided an additional revenue stream that offset a temporary decline in business from existing customers.Today, our plastics business accounts for 10% of our total turnover and, since 2020, as a direct result of our acquisition and investment strategies, turnover is up by 50%.”

Such impressive results, achieved through organic growth and by successfully entering new markets and sectors, is testament to G-Mach’s vision and values, and can be traced right back to 1993 when the company was first established.Then, operating as a one-man band from small, rented premises, and armed with a used NC lathe, a couple of manual machines and assorted tooling, G-Mach, led by Miller, began trading.

“Even in the early days, the focus was on delivering high-quality, added value and competitively-priced machining services, and on providing transparency and unrivalled customer service,” he says. “These same values and principles, which have stood us in good stead, remain cornerstones of the business today and will be for the foreseeable future.”

As far as the future is concerned, G-Mach, as one might expect, is not resting on its laurels.
To improve its machining capacity and capabilities the company will continue to upgrade its existing machine tool resources, trading in older models for advanced multi-tasking machines where appropriate.

G-Mach is also currently exploring the use and application of collaborative robot (cobot) technology to improve its productivity and part processing efficiencies.These potential investments, plus further redevelopment of its Melton Mowbray facility, will provide the company with a solid platform to achieve significant growth in the future.

With such an illustrious past and impressive track record, no one would bet against it happening sooner rather than later.

PROGRAMME OF INVESTMENT IN XYZ MACHINES PAYS DIVIDENDS

Matthew Boyt, managing director of CR Engineering in Wotton Underwood near Aylesbury bought the company from his previous employer in 2020 and since then has had a programme of investment in XYZ Machine Tools to keep up with demand.Originally formed in 1947, CR Engineering started off with watchmaking but now makes precision components for a wide range of applications including X-ray machines, bottle filling machines, bath lifts and specialist laser machinery.

“Before I bought the company and worked as an employee, Colin Rapsey, the previous owner, had already invested in XYZ Machine Tools, installing the first machine in 1998,” explains Boyt.“All the employees liked and were familiar with the ProtoTRAK controls and, the machines themselves had proved their reliability and return on investment, so it was an easy decision to continue working with XYZ Machine Tools as the business has grown.”

For turning, the company currently has three XYZ machines: a CT65 HD lathe with 66 mm capacity Hydrafeed bar-feed system, Siemens 828D ShopTurn touchscreen control and tool setting probe; a ProTurn RLX425 gap-bed lathe with 480 mm swing and 2500 rpm spindle (both purchased in July 2022); and a ProTurn SLX 355 with 1000 mm between centres which came with the company purchase.

For milling, the company’s XYZ machines include: a KMX 2000 turret mill with 762 x 380mm travel; an RMX 3500 bed mill with ProtoTRAK RMX control, 787 x 508 x 508mm travel and 5000 rpm spindle; and an RMX 5000 with ProtoTRAK RMX control, 1524 x 596 x 584mm travel and 7.5 hp programmable variable speed head. The latest acquisition is an XYZ 1100 HD vertical machining centre.

“This is my dream machine, and it would not fit in our previous factory,” says Boyt.“We moved to our new premises in August 2022, expanding our operation to 3600 sq ft. Purchasing this machine was one of the first things I did. We can fit three vices on the bed, so typically we can machine multi sided parts in one set-up, simply moving and turning them from one vice to the next to produce a finished part straight off one machine. Not only does this save on handling, it also improves accuracy and quality.”

The XYZ 1100 HD comes with a 33 hp, 10,000 rpm spindle, a 1200 x 600 mmtable and a Siemens 828D ShopMill 15″ touchscreen control or a Heidenhain TNC 620 control.

CR Engineering’s move to its new factory was orchestrated by XYZ’s haulage, moving the all the machinery and installing the new RMX 5000 in the space of one and a half days.

Says Boyt: “To recommission all the machines and install the new RMX 5000 so quickly minimised our downtime and was an impressive feat. Even better, the RMX 5000 paid for itself with the first job we put on it.”

The company specialises in small batch quantities of between 2 and 200 parts in a wide range of materials that include stainless steel, mild steel, aluminium, brass, acetel and nylon. Programming takes placeat the machine control, taking advantage of the easy ProtoTRAK, ShopMill and ShopTurn interactive conversational programming.

“We find this works well for the small batch quantities we make,” reports Boyt.“However, a really useful feature is the TRAKing on all the XYZ machines, which gives us the ability to run forwards and backwards through a program by turning the hand-wheel, quickly proving it out before hitting the start button, avoiding scrap and expensive damage to the machine.”

The investment in new machinery has impressed CR Engineering’s customers and it is seeing a growth in orders thanks to the large-capacity machines it has where some parts are up to 2.5m long. No one locally has the capability to machine components of this size. Similarly, the company is reaping the benefits of reshoring where customers are re-evaluating security of supply. CR Engineering is BS EN 9001:2008 registered, so accuracy, repeatability, traceability and on-time delivery are important parts of its ethos.

CR Engineering has nearly 70 years of experience in producing quality precision components for a wide variety of industries. The knowledge and skill within the company offers a refreshing blend between traditional engineering and modern current practice, allowing the customer to have confidence that both quality and service are available to them, as indeed it continues to be with many long term current customers. However, with Boyt now at the helm, the company is enjoying a new dawn based on investment in both capital equipment and staff.

“We now have 10 employees, adding a further four since I took over in 2020,” concludes Boyt.“Our staff are highly motivated and prepared to go the extra mile for our customers. Working with XYZ Machine Tools gives us the confidence that we can achieve our aims. The machines are well built and reliable, and the service is excellent. We hardly ever have any trouble with the machines and, if we do, it’s fixed the next day. We’ve found the machines to be very good value for money and will continue investing with XYZ Machine Tools as our business grows.”
