TW Ward CNC provide 'Two in One' Solution to Bo-Mac Sheffield

The installation of a new Takisawa Taiwan LA-250 L7 two-axis slant bed lathe killed two birds with one stone at Bo-Mac Sheffield by replacing an ageing machine and creating extra machining capacity due to its faster operation.


Being used by the South Yorkshire-based precision engineering firm to predominantly machine tool steel rollers measuring 250 mm long by 150 mm diameter for rolling mill guide equipment, the LA-250 L7 is enabling the company to effectively and efficiently carry out a wide range of fairly straightforward turning operations, according to co-director Kevin Mitchell.


'Our production of rolling mill guide equipment involves mainly uncomplicated turning tasks so, when we needed to improve our process cycle times, we knew exactly what we required from a new machine.


'We briefly looked at a variety of machines but soon settled on the Takisawa Taiwan model being offered by T W Ward CNC Machinery (Ward CNC). The machine provided all the capabilities we require and it was available on a quick delivery and at the right price. In addition, with two Ward CNC-supplied Hartford machining centres already on site for some time, we have always enjoyed good back-up and support from the company.'


The 76 mm bar capacity LA-250 L7 has a number of features that reinforce its cost-effectiveness. These include a 580 mm swing over the bed, a maximum turning diameter and length of 450 mm and 756 mm, respectively, a 254 mm standard chuck and a spindle speed of 3,000 rev/min.


The machine was put to work on a range of components at the company’s Sheffield site, which was established more than 30 years ago and today is involved in industry sectors such as automotive, construction, offshore oil and gas, fire prevention, wind power, catering and valve manufacturing.


Adept at supplying anything from one-off machined components through to assemblies, Bo-Mac’s production of the tool steel rollers is, says Mr Mitchell, on average in batches of 12-off.


'However, all the different sizes of rollers between them feature a wide range of profiles on the outside diameters, including ‘diablo v-type’ and rollers having one, two or three ‘peaks’ for slitting, so the variations between batches can be dramatic – hence the need for a machine that can easily and quickly be set up and run. And that’s exactly what we have with our new LA-250 L7.'
