Jena Tec launches new woodworking spindle range to UK market











Jena Tec launch into the UK market a complete range of compact, collet mounted electric spindles and accessories by Jena Rotary Technology Ltd (Jena Tec), a worldwide leader in the design and manufacture of machining spindles and ballscrews.





The machining of wood, plastics, glass, marble and light alloys become more readily available with the use of the GCR range of modular, square bodied spindles from Jena Tec.


The fan air cooled RV & RS series are manual tool change collet units with maximum speeds of 24,000RPM and up to 16 HP at a 60% duty cycle. Robust and lightweight in a rigid extruded alunimum body the lightest unit weighs in at 1.6Kg (3.6lbs). Collet size ranges from ER11 up to ER40 with a maximum tool shaft diameter up to 25mm. This spindle range is ideal for use in machinery for processing aluminium window frame extrusions, machines for routing of plastics and wood and robotic systems for deburring where weight and ruggedness are key considerations.


Moving up to the RC series, RPM’s of 60,000 can be achieved with compressed air cooling at 90% 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 (6.7lbs).
The specification and application of ceramic bearings within the GCR series allows much higher operating RPM up to 100,000.


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 re-building industry.


In addition to Jena Tec’s design capability in spindle technology, they also support the product range within its manufacturing plant for service and repair of the GCR range and that of other spindle manufacturers. The launch of this exciting new product range into the UK market signals a key strengh of Jena Tec to sell, design, develop and support its product range unrivalled by competition within its field.


The GCR product line for softer materials compliments the already extensive range of units produced and supplied by Jena Tec for milling, turning and grinding of traditionally harder metals. Jena Tec supply units for a wide range of machine tool, machinery and special purpose automation.

Jena Tec Assures OEM Spindle Test Quality





Jena Rotary Technology Ltd (Jena Tec), part of the Avingtrans plc Technology Group, saw the final installation and commissioning of a state of the art PC based Bosch test facility for motorised spindles in its Nottingham facility in May 2006.
Jena Tec is a leading UK supplier of ballscrews and machine tool spindle repair and replacement services to the aftermarket, OEM and factory automation industries and through the investment will be able to provide customers with a quality assured documented test programme.


Conventionally, machine tool spindles are tested using individual manually operated test equipment which requires operator intervention and is laborious to document, limited in scope and can be subjective in terms of interpretation and operator recording.
The new Jena Tec Bosch test rig allows for each spindle to have a unique record and test programme which is automatically programmed through a range of test cycles unmanned. Specific data can be captured and functionality of the spindle tested including;

•Motor Current logging
•Automated run in procedure
•Bearing Temperature & Lubrication
•Vibration Monitoring
•Encoder Performance
•Tool Clamp/Unclamp either hydraulic or pneumatic
•Drawbar switch setting
•Hydraulic actuation
•Cooling efficiency
•Air purge operation


What this means to machine tool customers, be they in the Aerospace, Automotive, Woodworking, Oil/Gas or precision engineering industries is that they can be assured of an OEM standard quality test programme for their repaired spindle. This can be subsequently audited and tracked to their specific test programme providing a higher level of assurance in the work conducted by the spindle repairer.


Jena Tec supply spindle and ballscrew repair services for a wide range of machine tool, machinery and special purpose automation. For more information contact Jena Tec at sales@jena-tec.co.uk or on +44 (0)1623 726010 or go to http://www.jena-tec.co.uk/
