1. Evaluation |
 |
Spindles for rework are received and logged into Jevco's repair
database. Each spindle is assigned an transport bin
and tracked throughout the repair. |
|
|
 |
Each spindle is disassembled into its major components and
all critical features and tolerances are inspected
for damage or wear. |
|
|
 |
An
estimate for the cost of the repair, including services
and parts, is generated and sent to the customer for
approval prior to any work being performed. |
|
|
|
4. Testing |
 |
• |
After
balancing and reassembly, vibration is measured and
recorded. |
• |
High-speed
dynamic run out is measured and recorded. |
• |
All
information, including amp draw, coolant flow, air
usage, static run out and dynamic run out is recorded. |
|
|
|
3. Balancing |
 |
• |
The
heart of a quality repair is a well balanced shaft. |
• |
All
armature shafts are balanced to less then .5mg/inch.
on our German built Schenk balancing machine. |
|

|
2. Repair |
 |
• |
New
replacement parts are installed per OEM specifications. |
• |
All
spindle components are thoroughly cleaned and reassembled. |
• |
Collet
taper is reground if total indicated runout exceeds
.00005". |
• |

|
5. Shipping |
|
|
• |
After
a spindle has been repaired to original equipment

|
|
 |
|
Balancing A |
 |
Our balancing
machine utilizes air bearings to properly balance a Westwind
armature shaft, and ABEC 7 High speed instrument bearings
to balance conventional ball bearing shafts to measurements
reading into micro grams allow correction to exceed new
O.E.M specifications. |
|

Balancing B |
 |
The polar
indication is presented to the operator on two vectrometers
as well as the exact digital indication.
-Imbalance measurement range:
-1:2,000,000.
-Imbalance tolerance:
Air Bearing Spindles – Less then .5 mg
Ball Bearing Spindles – Less then 1.0 mg -Balancing
speed range:
-120... 100,000 rpm |

Runout Testing |
 |
The Targa II system is used to measure and display the Total Indicated
Runout and RPM of high speed spindles during the testing phase
of your repair. By understanding the relationship between
runout and RPM you can be assured of the optimal performance
of your spindle at all operating speeds.
Total indicated Runout Testing
Air Bearing Spindles – 8 µ meters (with most being
less then 6 µ meters)
Ball Bearing Spindles – 12 µ meters |
