Beyond the 32 mm barrier

With the arrival of the Delta 38/5 machine, Tornos has slightly increased the range of parts that can be produced through traditional bar turning. With a capacity of 38 mm, this turning machine, which has 5 linear axes and two C axes, and can hold up to 31 tools, offers a number of concrete advantages to boost its market appeal. Customers are not mistaken.

John Mc Bride, sales manager in the UK, explains: “The Delta 38 machine has provoked a lot of interest among our customers; not only does it offer them a lot of extra dimensional capacity, it’s also a very robust and rigid machine which allows them to remove a great deal of material. The spindle/guide bush system with integrated motor also allows the drop length to be drastically reduced compared to conventional technology”. Tornos has just unveiled a new version of this machine: The Delta 38/5BL operating without a guide bush. The Delta 38/5 machine is a little closer to an “all-purpose” machine.

High torque and power
The turning machine is ahead of the main direct competitor machines in terms of both diameter and power. Weighing 4.6 tonnes, with a main spindle generating a maximum power of 11 kW and a torque of 70 Nm, combined with 20×20 cross section turning tools this is a high-performance machine which can remove large quantities of swarf.

With or without guide bush? It’s up to you
For producing short parts (length up to around 2.5 times the diameter, maximum 100 mm), Tornos recommends the Delta 38/5BL. Operating without a guide bush, this machine can be used to machine bars with a lower level of finish than is obtained on a version with a guide bush. This can result in savings on the cost of materials.

Substantial savings
Not only is the loaded material less expensive; the drop length is also reduced as much as possible. “For short parts, the BL machine is a must. The diametric tolerance of the raw bar becomes less critical and the drop length is reduced to its simplest form; this helps to bring down material costs”, explains marketing manager Brice Renggli. The machine is very competitively priced, meaning users benefit on all fronts.

The Delta 38 will be on show at AMB (hall 3, stand C14) and IMTS (S-8666)
