With the recent addition of an own product involved with fire suppression to its highly successful sub-contract machining operation, HPC Services of Ilkeston, Derby, has ordered the latest Citizen Cincom L20-VIIILFV turn-mill centre. By including Low Frequency Vibration (LFV) machining technology in the specification, Managing Director of HPC Paul Cobb maintains this will give his business a lead in the market by revolutionising his production of materials such as 321 corrosion resistant and 416 chromium steel alloy stainless steels and plastics type materials.
Said Mr Cobb: “This machine will enable us to competitively quote on new work which we would normally decline and will give us additional capacity as we build up production on our in-house developed water-based fire suppression system.”
HPC has currently 10 Citizen Cincom machines installed, with the last Cincom L12-VII currently very competitively producing components as part of a 40,000 a year contract. The plastics tube, 110 mm in length is turned and a hole produced through its length to a concentricity tolerance of 0.05 mm TIR. Said Mr Cobb: “So productive is the machine that we have reduced our cycle time from over a minute to just 12 secs.”
The ability for the operator to control the size of chip produced eliminates problems such as ‘bird-nesting’, improves depth-of-cut and surface finish, delays the onset of built-up edge on tooling and dramatically aids the management of swarf. It can be applied to turning, profiling, facing, taper and interrupted cutting sequences plus drilling and even thread cutting over a wide range of materials from plastics, aluminium and copper to high tensile stainless and other high grade steels.
Mr Cobb said: “Swarf control is a bugbear on certain materials and needs constant attention to prevent birds-nesting and swarf being picked-up with the part as it is transferred to the sub-spindle of the machine. On some highly critical workpieces we even have to allow for a grinding operation to remove marks caused by swarf. This is where LFV will transform our operations.”
Our machines cover 1mm to 64mm and above. Fast to set, quick to changeover and easy to use our technology represents a sound investment. We invite you to take a look at our range.
