    Citizen turns a miller into a turner at Stratos

    Operating out of an 8,000sq/ft CNC machine shop in Gloucester, Stratos Precision Engineering, is a manufacturer of machined plastic components. With a machine shop that largely consists of HAAS machines, the subcontract manufacturer was encountering issues with plastic swarf when machining batch runs. To counteract this, the company invested in a sliding head turning centre from Citizen.

    Commenting upon the Citizen L32 LFV purchase, Stratos’ Mr Jon Caple says: “We have a range of conventional machinery, and we felt the Citizen machine could help make more parts. We have milling, turning and routing parts that we felt would be better on this type of machine.”

    Referring to why the company selected a Citizen machine, Mr Caple said: “We went to Brierly Hill where Citizen put a ‘day’ on for us and this made our mind up. We placed the order there and then because the machine would do everything we wanted.”

    Discussing this, Mr Caple continues: “We needed a machine for cutting plastics, that on a fixed-head would create bird nesting of swarf and material would burn onto the tools creating surface finish issues. With the LFV on the Citizen L32 LFV machine, the swarf is chipped away. This allows us to run 24/7.”

    Commenting on where this machine will take Stratos in the future, Mr Caple continues: “We can now run parts that we lost out on before. This is bringing business back in-house and opening doors for new opportunities; we are now also looking to attract new markets. Being a 7-axis machine, it can achieve things that we couldn’t do on our conventional kit.”

    Demonstrating the capabilities of the Citizen machine to improve business, Mr Caple recalls: “One particular part we manufacture is an acetal spacer. We were making quantities in the thousands, but we lost out on this part to a moulding company that could produce the part a lot cheaper and faster. The new machine has opened this back up for us and we have come in under the price of the moulding company, which we did not expect to do.”

    Turning to a Miller

    The ease of use of the new machine is perfectly epitomised by Simon Wells at Stratos. He spent 15 years as a machinist, primarily operating 3-axis HAAS CNC machining centres and commenting upon the step-up to a multi-axis machine, Mr Wells says: “Moving from a 3-axis CNC machining centre to a 7-axis sliding head-turning centre has certainly been a challenge. However, the process had been simple with Citizen. They supplied all the training and helped me loads. The machine has a Mitsubishi CNC control system, which is very easy-to-use with the help of the Citizen training programme.”

    This ease of use is demonstrated throughout the machine, as Mr Wells says: “The machine accommodates parts from 3mm up to 36mm and it only takes half an hour to change the bars out and set the machine up for different size bars.” Referring to the LFV system, Mr Wells continues: “The Wizard does all the hard work for you with the LFV system – it really is very easy.”

    With regard to the setup and tooling configuration, Mr Wells beams: “We have 30 tools in the working envelope and with the manual B-axis, we can reconfigure this quickly and easily.”

    Looking at some of the parts on the Citizen machine, Mr Wells says: “We frequently turn Nylon, and this used to leave big bundles of swarf around the tool and workpiece during machining. We had to stop production on every single part just to clear the stringy swarf, additionally some parts would melt. With the LFV we can turn thousands of parts without even opening the door of the machine.”

    Referring to a small PEEK nut, Mr Wells says: “These used to undergo two operations, the first-op would be turning and the second operation would be on a machining centre – we have now eliminated the secondary setup and cycle, which saves us a lot of time. Another part we machine is a 6mm diameter washer, the Citizen machine can run thousands of these whereas our previous machine created burrs.”
