How to select spindle repair services?
It requires a complete understanding of spindle technologies to select any kind of spindle repair services. For example, bearings are used to provide clearance and permit rotary motion without eliminating wear and friction and physical contact, thereby facilitating high speeds. Bearings are of various types. Again there are spindles mount in a block or cartridge-style housing or bolted in place with the use of flanges or feet. Spindles with angled head configuration allow adjustable tool or right angle rotation. Spindles that perform the tasks of milling, turning , drilling fit the heads of different machines include gearing to multiply the spindle speed and so on.
Certifications and quality requirements
There are various certifications and quality requirements for spindle repair services. The various certifications are
- ISO 9001: This provide requirements for organizations whose
business involves design and development, production, installation,
servicing.
- ISO 9002: This provide requirements for organizations whose
business involves production, installation, servicing, but not design
and development.
- QS 9000: Based on the 1994 edition of ISO 9001 with additional
requirements particular to the automotive industry, this is the must
have quality standard for suppliers of Ford Motor Company and General
Motors Corporation etc.
- OEM specifications: Another quality certification available on spindles is by original equipment manufacturers (OEM) to repair spindles according to specified tolerance and conditions.
Classifications of spindles repair services
For any manufacturer or supplier of spindles, it becomes very necessary to provide the following services as spindles repair services for its customers:
- Inspection of disassembled spindle: This service includes
determining possible spindle crash, overheating, improper bearing fits,
improper tooling, use of spindle after initial failure, lack of lube or
overloading.
- Condition of bearings: This service is performed under
laboratory conditions to determine over speeding, spindle crash, lack of
lubrication, overloading, loss of pre load, contamination or
overheating.
- Engineering recommendations of spindle repair: This service
includes various suggestions of spindle design changes or improvements
to spindle longevity and performance.
- On-site training and preventative maintenance: This service
is a must for all spindle suppliers to give proper guidance on spindle
care and installation, appropriate alarm levels and predicting imminent
failures.
- Repair, rebuilding of spindles: Repair or rebuilding of
spindles become very necessary in spindles used in lathes, milling
machines, grinding machines and various other machine tools.
- Component evaluation and replacement.
- Clean room assembly.
- Inspection and quality control.
- Failure analysis.
- Dynamic testing.
- Vibration analysis.
- Spindle speed range upgrades etc.
Additional services
Spindle repair services also provide some other services, in addition to above. Of course, this depends a lot on customer's recommendations. For example:
- Some manufacturers use computer aided design or drafting (CAD) to
design products quickly and accurately and computer aided manufacturing
(CAM) is used to fabricate spindles from these CAD outputs. Such
companies that provide design assistance can also help the customers in
providing
- Concepts
- Manufacturing costs
- Manufacturing techniques
- Material considerations for various types of spindles
- There are certain repair services that can rebuild machine tools or provide refurbished spindles or provide on-site support or warranty repaired products.
