Vertical machining centre gives high performance

XYZ Machine Tools offers a high performance vertical machining centre fitted with an oil-cooled main spindle and linear roller bearing ways for vibration-free machining.

XYZ Machine Tools' XYZ 1060 HS vertical machining centre (VMC) is a high-performance machine tool fitted with NSK linear roller bearings.

The company said it gives vibration-free 43m/min rapid traverses in X-, Y- and Z-axis.

Strategically placed ribs in the Meehanite cast iron base ensure maximum rigidity and give excellent load bearing performance and damping capability.

The 15kW VMC accepts workpieces weighing up to 800kg on a 1200mm by 800mm table.

Having a main spindle rated at 15kW (20HP), the XYZ 1060 HS has a standard spindle apeed of 12,000 rev/min.

Optional maximum spindle speeds can be optionally specified at 15,000, 18,000 and 24,000 rev/min.

The oil cooled main spindle spindle delivers coolant at 20.4 kg/cm2 to flush chips and dissipate heat when machining blind holes and deep cavities.

The spindle oil cooler fprovides temperature control within +/-1 deg C, said XYZ and the spindle is supported in ceramic bearings, which have been dynamically balanced to give smooth and accurate cutting performance.

* CNC system - the XYZ 1060 HS is equipped with the easy-to-use Siemens 840D ShopMill conversational CNC.

XYZ said that although the Siemens 840D CNC contains powerful conversational programming routines, there are occasions when CAD/CAM may be used to generate a program.

The CNC's four millisecond block processing time allows the handling of large amounts of data and, in combination with the Siemens Compcad spline interpolator function.

This arrangement, said XYZ, ensures that however complex the component's surface profile, optimum feed rates will be maintained and a high quality surface finish achieved.

* Tool magazine - a 24-tool capacity tool magazine holds tools weighing up to 8kg, with 'pre-selection' of tools contributing to a 2.5s tool-to-tool change time.

The XYZ 1060 HS, which weighs 7500kg.
