Heavy-duty turning centres lighten the load

Now available in the UK and Ireland from official importer, sales distributor and sales agent, TDT Technology, is the Feeler range of FTC turning centres and slant-bed CNC turning centres. Aimed at machine shops tasked with heavy-duty machining operations, the machines are designed to offer a competitive cost-to-performance ratio.

The Feeler FTC range comprises three models, the FTC-10, FTC-20 and FTC-30. Between them, the machines cover a swing-over-bed of 520 to 600 mm diameter, a standard turning diameter of 180 to 310 mm, a maximum turning diameter of 240 to 450 mm, and a maximum turning length of 255 to 621 mm. All three feature a spindle equipped with precision, dual-direction, angular-contact thrust ball bearings, while a special heat-dissipation headstock design eliminates elevated temperatures from the spindle bearings, prolonging life and promoting reliability.
TDT says that machines in the Feeler FTC series of slant-bed CNC turning centres are designed for rigidity, efficiency and versatility. Kicking off the range is the FTC-300, which features a 6000 rpm spindle, 6” chuck and 52 mm diameter bar capacity. Moving up, the FTC-350, 350L, 350XL, 350LY (Y axis) and 350SLY (twin spindle) offer a 4500 rpm spindle, 8” chuck and 52 mm diameter bar capacity (66 mm option). All feature a 30° slant bed.
For an even more robust structure, the FTC-450 and 450MC (C axis and driven tools) provide a 45° slant bed, a maximum turning diameter of 450 mm and a maximum turning length of 650 mm. Finally, for the range’s highest power and rigidity, the FTC-640 and 640L again feature a 45° slant bed, which is matched with a 15” hydraulic chuck, 117.5 mm bar capacity, 22/26 kW spindle motor and A2-11 heavy-duty spindle.

Latest Y-axis, sub-spindle turning centre

The next-generation Y-axis, sub-spindle Doosan Puma 2600SY Mk II turning centre series is now available from Mills CNC. Although the new machines are equipped with a 10” chuck, unlike Puma 2600SY Mk I models, they have a larger 81 mm bar diameter capacity. The machines are also supplied with built-in type spindles (as opposed to belt-driven spindles), which generate less vibration during cutting operations.

Further innovations include six strategically positioned heat sensors that automatically monitor and compensate for any thermal displacement during machining operations. In addition, the spindles feature a reconfigured bearing structure comprising two angular-contact bearings and two taper roller bearings to improve C-axis positional accuracy and spindle runout (less than 6 µm).
The Puma 2600SY Mk II uses high-performance NTN material (as opposed to Turcite) on its box-guideway axes, a move that is said to result in improved and more responsive movement, and reduced wear. Other performance improvements include a revised design of milling turret that incorporates a Curvic coupling piston structure delivering up to 12% additional clamping force; improved durability of the Y-axis carriageway; and a spindle air-purge function that helps prevent chip and coolant ingress.
The machine was exhibited for the first time in the UK at the recent Mills CNC open house, which took place in October.

Attendance climbs

The organisers of Advanced Engineering 2017, which was held at the Birmingham NEC last month say that the exhibition’s final attendance figure was 15% higher than in 2016.

Furthermore, success at the show has sparked a booking frenzy for the 2018 edition, with stand reservations 35% higher than at the same point the year before. The show consisted of five co-locating zones: Aero Engineering; Composites Engineering; Automotive Engineering; Performance Metals Engineering; and Connected Manufacturing. These will be joined by Nuclear Engineering at the 2018 exhibition (31 Oct to 1 Nov).

AM collaboration

Schaeffler Technologies, which manufactures roller bearings and owns the INA and FAG brands, has entered into a co-operation agreement on additive manufacturing with machine tool manufacturer DMG Mori.

Schaeffler is now using a DMG Mori Lasertec 65 3D hybrid machine to produce one-offs and small batches of bearing components, as well as spare parts in metallic functionally graded materials (FGM) to finished-part quality. The one-hit process combines the flexibility of additive manufacturing by laser deposition with five-axis subtractive milling.
