Type of machine:	Round Grinding Machines
Description:	Round Grinding Machines KELLENBERGER Kel-Varia UR225-1500 1-2-6-7 used machine grinding diameter: 450 mm grinding length: 1500 mm centre height: 225 mm Control: total power requirement: kW weight of the machine ca.: t dimensions of the machine ca.: m EQUIPEMENT - T1: grinding wheel diameter 500 mm - T2: grinding wheel diameter 400 mm - T6: HF Fischer spindle MFV or MFZ 1224/1242/1260 - T7: HF Fischer spindle MFV or MFZ 1224/1242/1260 - Marposs tool measurement - active longitudinal positioning - Elaso GAP-control on T1 and T2 contactless integrated in the control surface - Elaso GAP internal grinding with fluid sensor for T6 and T7 - semi-automatic balancing by Elaso integrated in the control surface for T1/T2 - tailstock hydraulic with fine adjustment +/- 150 microns - dresser on workpiece spindle side table mounted - dresser on tailstock side table mounted - dresser on upper table - new service- and userfriendly housing SPECIAL EQUPEMENT: Workhead with direct drive - strongly recommended for non-circular grinding - workpiece weight flying max. 75kg - workpiece weight between centres 150kg - water-cooled B-axis with direct drive - center height 225 mm - extremely torsionally stiff - highly accurate positioning - resolution 0.000001341° - water-cooled Hydrostatic ball screw - x-axis - wear-free, as there is no contact during operation - no loss of precision, even during long-term use at full load and maximum speed - no friction at low speeds - no friction force backlash when the direction of rotation changes - translates even the smallest rotational movements - no stick-slip effect even at low speeds - no fluctuations in frictional torque due to ball circulation - higher axial stiffness compared to ball screws - significant improvement in damping, resulting in better workpiece surface finish and tool life - no oscillations due to ball circulation - also suitable for high speeds and accelerations - cost-effective alternative to the linear motor with greater precision and significantly lower heat generation - significantly less power dissipation and, as a result, no problems with swarf on permanent magnets New hydraulic unit - optimized temperature control (chiller) - Energy-saving Only one pump controlled by VFD - Pressure monitoring - monitoring of the hydrostatic oil for water content. (Damage to the bellows is recognised and detected prematurely) -fine adjustment +/- 150 microns Paper belt filter 375l – alternative 480l Grinding mist extraction system – emulsion MECHANICAL OVERHAUL -complete machine according to Kellenberger protocoll -new painting ELECTRICAL OVERHAUL - new modern Fagor CNC with BEMA HMI - new electric cabinet - new digital drive technology - replacement of all electrical cables, switches etc. - new absolute external scales in x- and z-axis - new absolute encoder (B-axis) Grinding software BEMA-Standard: - workpiece zeroing - grinding wheel B4113074 zeroing - dressing diamond measuring - corrections - external and internal surface grinding - external and internal angle grinding (turning of the b-axis, dressing with straight wheel) - external and internal radius grinding (radius dressed on wheel) - semi-automatic traverse grinding - workpiece zeroing - 2 dressing diamonds - 1 dressing blade - dressing roll - 3 flat dresser - corrections - Z-position measurement - GAP control Optional grinding cycles at no extra charge: Profile plunge grinding: - external and internal profile plunge grinding with profile wheel Profile grinding: - external and internal profile grinding with straight wheel Software thread grinding: - single- and multiple-start external and internal thread. Grinding with thread dressed on the wheel Dressing of single and multi-groove disc Flank angle freely selectable. Trapezoidal thread grinding: - Additional dressing of trapezoidal threads possible. Non-round grinding: - external and internal non-circular plunge-cut grinding - external and internal non-circular oscillating grinding The data for this ad was created with ModulMWS - the software solution of LogoTech oHG. seller offer No. resale 1056-M24Vari
