SPINDLE GRINDING
[flagallery gid=2 skin=minima_jn align=center]
WHAT ARE THE SYMPTOMS OF ERRORS IN THE SPINDLE ?
- Surface quality deterioration,
- Loss of sensitivities,
- Breaking and early blunting of cutting tools,
- Different sizes of the same work, especially in serial production,
- Increase of fluctuations and traces in hand by face milling,
- Reading of different error values in each change in the same toolholder,
- The formation of marks in a short time especially in the new holders’ cones,
- Formation of copper colored rust on tool cones,
NEGATIVE EFFECTS OF WORKING WITH BLASTED SPINDLE:
- 30 µm distortion on Spindle reduces cutter life by up to 50%
- Vibration caused by distortion, causes bearings to break down.
- Loss of processing time.
- Causes tool breakage and work accidents at high speeds and heavy swarf.
- Problems that can be prevented at small costs can turn into big economic losses.
BURMAKSAN WITH YOU !
Processes, 100% grinding techniques and methods, total precision not exceeds 3 µm !.1
- Since the spindle will not be removed; loss of time, supply of new bearings, additional cost of dismantling and, most importantly, the possibility of capturing the sensitivity of the original assembled state.
- Loss of business is minimal, as the process can be done outside working hours or on holidays.
- No axis of the machine is moved during the process, then there is no problem about sensitivity.
- Maximum surface quality is obtained as Rzmax : 2.5 µm.
- Since the grinding device is completely CNC controlled, very precise results are obtained.
- At the end of the service, spindle state, tool pulling force, conical form error rate, spindle vibration characteristic and bearing error reports are given.
CONES CAN BE GRINDED :
> DIN 2079 Norm ISO 30 – ISO 40 – ISO 50 Cones.
> DIN 69893 Norm HSK 32 – HSK 100 Cones.
