Hurco Helps BAW Hit Niche Markets with its 5-axis CNC Machining Centre
When BAW Precision Engineering Ltd emerged from the global downturn under new ownership in July 2010, the primary aim for the new directors of the Swansea Valley company was to build the order book and re-establish the subcontractors’ prestigious reputation.
The re-emergence of one of Wales leading subcontractors commenced less than a year ago with the introduction of new management, employee training and a lean manufacturing philosophy. These building blocks have been supported with new sales and marketing structure that can now promote the new capabilities provided by the subcontractor’s latest asset, a new 5axis machining centre from Hurco.
Already boasting marquee customers such as Biomet, The Royal Mint, Honda, Continental Teves, Walkers Foods, Borg Warner and Bosch to name a few, the diverse customer base sees BAW work in the medical, aerospace, automotive, power generation and hydraulic sectors among others. This extensive subcontract expertise is supplemented by an internal department that boasts one of the UK’s few specialist concept to component automation machinery builders.
With both departments increasingly winning new business, a new machining centre was a necessity. As BAW Precision’s Operations Manager, Mr Andrew Hoseasons comments: “The new ownership and internal developments at BAW has delivered an influx of new business and despite already having 3+2 axis set-ups on our existing machines, we acknowledged that we needed full simultaneous 5-axis capability to drive the company forward. We have identified a need in the marketplace and the new Hurco will be our first step to filling this gap in the market.”
When Pontardawe based BAW entered the market for a new 5-axis CNC machining centre, the fact that the company already has nine Hurco machining centres purchased over a period of 20 years, influenced the decision. As Mr Hoseasons continues: “Despite having an excellent working relationship with Hurco, we still investigated the marketplace to review and consider alternative suppliers. However, we quickly found that the Hurco VMX30U was the most suitable machine for the type of parts we produce. Additionally, our experience informed us that Hurco machines offer exceptional reliability and user friendliness that is matched by excellent performance and productivity levels.”
Emphasising such points, Mr Richard Gunn, Group Engineering Development Manager of RG Tooling, BAW’s development arm, is keen to highlight the immediate impact of the Hurco VMX30U with its integrated Trunnion table. “At present we are machining toolholders for sister company Eurogrind, a manufacturer of standard and bespoke milling and turning toolholders. The simultaneous 5-axis machining has already slashed production times. Previously, our square shank toolholders underwent three individual set-ups that took 10 minutes each. Added to the set-up times were three machining cycles of 15 minutes each, resulting in a complete part time of 75minutes per toolholder. Now, the new VMX30U only requires one ten minute set-up and one 15 minute machining cycle.”
As one of the first jobs on the new Hurco, BAW are delighted with a time saving of 50 minutes. The company initially expected the VMX30U to deliver productivity gains of 25%; however this one job has delivered a saving that has surpassed 60%. This is credit to the reduced set-ups, efficient 5-axis tool paths and higher speed and feed rate capabilities. To put the saving in perspective, BAW machines the toolholders in batches from 10 to 30 with an annual production exceeding 500 units.
Whilst the production times are being cut, Mr Gunn is keen to emphasise the benefit of the new Ultimax control system on the new acquisition, stating: “We have always found the Hurco control system easy to use, but the latest version takes user friendliness a step further. Each function box offers a foot note prompt that tells the operator exactly what to do, making errors difficult to make. From a productivity standpoint, we specified the twin-screen control. This enables us to machine a part with the existing program running on one screen whilst the operator can simultaneously program the next part on the second screen. As the majority of jobs passing through the machine will be small batches of 1 to 10-offs, this will drastically reduce programming times and improve operator productivity, especially as 90% of jobs are programmed on the shop floor.”
“Other features on the Hurco Ultimax control that already benefit us, is the ‘surface finish feature’ that improves cycle times by automatically increasing or reducing speeds and feeds according to the cycle. Additionally, the new control has a transfer plane command that takes the trigonometry calculations out of any programming. It also enables us to merge NC code with intuitive 5-sided conversational programming, further simplifying and speeding up the programming process,” continues Mr Gunn.
One of the niche markets BAW is targeting is the oil & gas and hydraulic valve sector. The company set this strategy in motion when specifying the VMX30U that was installed in February 2011. The trunnion table with a 420mm face plate accommodates a diverse range of chucks and is ideal for producing complex valve components. As Mr Hoseason concludes: “We identified a gap in the marketplace and acquired the ideal machine for such complex components. This acquisition has enabled BAW to expand its target markets. When we promoted our extended capabilities and new machine at the recent Southern Manufacturing Exhibition, we had a major success winning over 15 new customers and significant orders in the process. Looking to the future, we will be implementing AS: 9100 to get a stronger foothold in the aerospace market. We will also be adding to our plant list – and with immediate impact of the Hurco VMX30U, there is little doubt we will be specifying Hurco machines in the future.”
