Compact electric spindles spin at up to 100,000rpm
Jena Tec is launching a complete range of compact, collet-mounted electric spindles and accessories. The machining of wood, plastics, glass, marble and light alloys is said to be become more readily achievable using this new GCR range of modular, square-bodied spindles.
The fan-cooled RV and RS series are manual tool change collet units with maximum speeds of 24,000rpm and up to 16HP power output at a 60 per cent duty cycle. Robust and lightweight in a rigid extruded aluminium body, the lightest unit weighs just 1.6kg. Collet sizes range from ER11 to ER40, with a maximum tool shaft diameter of 25mm.
This spindle range is suitable for use in machinery for processing aluminium window frame extrusions, machines for routing plastics and wood, and robotic systems for deburring where weight and ruggedness are key considerations.
Moving up to the RC series, speeds of 60,000rpm can be achieved with compressed air cooling at 90 per cent duty cycles with similar tool diameters at much higher speeds for more intensive machining operations. Again, weight considerations are paramount, with a base unit starting at 3kg. The specification and application of ceramic bearings within the GCR series allows much higher operating speeds of up to 100,000rpm.
The vast majority of the GCR spindle range is also available with auto tool changer options for ISO and HSK tool interfaces. Due to the modular nature of the spindle units, it is normally easy for existing users of machines to change an existing spindle from another manufacturer for a GCR spindle with little or no modification - which is of key benefit for the end user and machine tool rebuilding industry.
Support services
In addition to Jena Tec's design capability in spindle technology, the company also supports the product range within its manufacturing plant for service and repair of the GCR range and those of other spindle manufacturers. Jena Tec says the launch of this exciting new product range into the UK market highlights its ability to sell, design, develop and support its product range, which the company says is unrivalled by competitors.
The GCR product line for softer materials complements the already extensive range of units produced and supplied by Jena Tec for milling, turning and grinding harder metals. Jena Tec supplies spindles for a wide range of machine tool, machinery and special-purpose automation. For more information contact Jena Tec.
