CNC Vertical Turning & Boring Machines CNC Vertical Turning Lathe

Premier Limited is a pioneer in the manufacturing of state-of-the-art CNC Vertical Turning Lathes (VTL), with sizes ranging from small VTLs to large VTLs. Based on the sizes the products are classified into PTA,PTB,PTC and PTD series.

PTA Series

Premier’s PTA series of machines are small range of CNC Vertical Turning Lathes designed to cater to the needs of small components like valves, pumps and auto components. This series is very compact and cost effective.

3 jaw hydraulic self centering chucks and 8 station turret with standard tool disc are offered as standard features in this series. However live spindle with C-Axis, 12 station turret and magnetic chuck can be offered as an option in this series.

PTB Series

Premier’s PTB series of machines are medium sized robust CNC Vertical Turning Lathes ideally designed to turn components upto 1800mm diameter. The machines in this series have a table diameter of 1000mm -1800mm and a swing diameter of 1600mm-2000mm. This series of machines are available either with ram or turret and can be customized for various other features. Standard features in this series include fixed cross slide, manually operated 4 jaw chuck and 2 speed table drives. However moving cross rail, higher admit under the cross rail, high table speed, high motor power and ram in place of turret can be offered as an option. The X axis and Z-axis traverse in this series of machines are provided with linear scales for high positional accuracy and repeatability.

PTB 125

Helps to maximise positional accuracy. The table has been reconstructed to rotate on the C axis mode and drill on pcd and bore at a centre. This helps in slot milling and contour milling

PTB 150

Premier’s CNC Machines division is a market leader in the machine tool industry, engaged in producing machines widely used in all industrial segments promoting automobile, aerospace, power generation, railways, defence, etc.

  • The journey initiated from manufacturing conventional machines to now high-speed CNC gear cutting machines, vertical turning machines and special purpose machines which cater to the increasing global demand.
  • Premiere’s PTB series of machines comes with a standard ram of 240 mm which holds the turning and milling tools either steady or live.
  • The PTB machine provides components for the power sector, like turbine rotor and stator, as well as those for locomotive and rail coaches, defence components and the machining of large size valves.

PTB Machines produced by Premier till date.

PTB 80

Our CNC machines are constantly improved and updated to enhance performance by reducing production speed and cost.

Introducing the PTB-80. Features and advantages of this Single Column Vertical Turning and Boring machine include:

  • Maximum turning diameter of 1000 mm and swing diameter of 1100 mm. Standard turning diameter of 620 mm for a turning height of 800 mm. The table is designed to carry the load of 2000 kg. Maximum speed of table: 600 revolutions per minute.
  • Machine mainly used for valve and pump components, turning of big diameter gears and pulleys in the Heavy Engineering industry.
  • The turning diameter and swing diameter help to machine larger and heavier components giving an added advantage over the PTA-80.
  • Roller type linear motions guide are provided for x and z axis motion versus the solid rectangular guide way that was used in the PTA-80, resulting in smoother functioning. This speeds up the entire process and reduces production cycle time.
PTC Series

The PTC series of machines are modern CNC Vertical Turning Lathes meant for boring and milling operations with live spindles. This series of machines come with table upto 2500mm diameter and the maximum load carrying capacity on the table is 25 tonnes. These machines come with hydrostatic guideways,12 station floor mounted ATC , moving cross rail, swiveling pendant,4 jaw box type chuck and fully enclosed splash guard and are available as standard features. Grinding attachment and angular milling attachments can be mounted on the ram. However additional ram, automatic pallet changer, tool probing system can be offered as an option.

PTD Series

The PTD series of machines are heavy duty CNC Vertical Turning Lathes with table diameters upto 5000mm and swing diameters upto 6000mm.These are double column machines with single ram or 2 rams one on the left side and the other on the right side. These machines are with a thermo symmetric base.

These machines come with C-Axis with backlash free arrangement, tables with hydrostatic bearings, X and Z axes with hydrostatic guideways, live spindles, as standard features. The maximum load carrying capacity on a 5000mm diameter table is 50 tonnes. The X and Z axes in these machines are driven by precision ball screws and servomotor arrangement. These large sized machines are ideally used in heavy industries manufacturing windmills, power product and turbines, etc.

Either Fanuc or Siemens make CNC systems may be offered with these machines.
