Many prismatic machining contracts ideally take place on a five-axis machining centre, which enables components to be produced cost effectively. A problem arises, however, if the parts do not command a high selling price.

Subcontractor G&J (CNC) Services in Paddock Wood has apparently found a solution: the Leadwell V-30iT 3+2-axis BT40 machining centre from WH-Lead, which says the entry-level price of less than six figures belies the five-axis machine’s extensive capabilities. According to G&J (CNC) Services, the hourly rate that the subcontractor charges based on the investment allows the efficient production of less complex prismatic components at prices which compare favourably with those quoted by competitors in low-wage countries.

The company’s owner Charlie Naismith says: “Depending on the value of the parts being machined, which is normally down to their complexity and the material used, you have to make sure the figures add up. Much of our throughput is fairly simple 3+2-axis work in mild steel and aluminium that customers will not pay a premium for, so the Leadwell machine is perfect.

Continues Naismith: “We actually use it in three-axis mode for much of the time, but the five-axis functionality is there for when we need it, saving costs associated with workholding, handling and work-in-progress. At the same time, it helps with accuracy by being able to access parts with shorter tools and by cutting down on manual re-fixturing.”

He also appreciates the ergonomics of the V-30iT, pointing out that the rotary table when flat is at the same level as the fixed table, so there are no clearance issues. Control is provided by a Fanuc 0i-MF Plus, although Siemens, Fagor and Heidenhain are optional, as is the specification of 4+1 or full five-axis interpolation.
