Used/completely overhauled surface grinding machine, make ELB, type HK Orion 835 NPC-K
Overhaul Scope:
Machine completely disassembled, all components thoroughly cleaned and checked for complete functionality.
All guideways re-scraped to new machine geometry.
Wearing parts replaced, defective components repaired or replaced.
Reassembly of the dismantled components, compl. Functional test and internal acceptance.
Machine repainted in reseda green RAL 6011.
Machine in perfect, production-ready condition.
Geometric Accuracy:
Measured after the overhaul
X-axis 800 mm magnetic plate length with dial gauge, max. deviation 0.005 mm
Z-axis 350 mm magnetic plate width with dial gauge, max. deviation 0.004 mm
Spindle concentricity: max. dimensional deviation 0.003 mm
Machine design and accessories:
- Machine bed made of MICRO granite (optimal rigidity, excellent vibration behavior, high thermal stability, high accuracy, improved long-term accuracy).
The guideways of the X and Z axes are designed in a V-flat shape and are plastic-coated (Turcit-B)
- Preselectable vertical and transverse feed with digital display for both axes. Description attached as "NPC-K grinding program".
- Speed control of the grinding spindle
Grinding spindle drive: 3.5 - 10.5 kW
Grinding spindle speed: 1000 - 3000 rpm
- Fully automatic grinding program with digital preselection of the workpiece nominal size.
- Electric straight dressing device for automatic dressing of the grinding wheel, mounted above the grinding wheel.
- Automatic grinding wheel dressing compensation (an incremental measuring system for the vertical axis and a measuring system for the infeed of the dressing device record every movement of the grinding unit and the wear of the grinding wheel. These values are compensated by the control. The main advantage of this control is the flexible changeover to other thicknesses and the high switch-off accuracy when the target dimension is reached).
- Electro-permanent magnet clamping plate 800 x 350 mm, with fine transverse pole pitch.
- Magnetic disk supply system with adhesive force control.
- Complete coolant system with paper band filter.
- Hydraulic system in modern monoblock design, easy to maintain and connected to the coolant system (separate tank in the coolant tank).
- 1 piece grinding wheel flange
- 1 piece of used grinding wheel
- Complete technical documentation in German
- Operating voltage 400/24 volts, 50 Hz
- Installed power: 9 kW
