Grinding Spindles Repaired

We offer quality grinding spindles, accessories, and Walter Dittel GmbH control systems optimized to reduce grinding time and wear. Our grinding spindles provide unsurpassed versatility, speed, thermal stability, power range, and reliability at an outstanding value. We are a leading sales and service provider of superior quality precision horizontal spindle, vertical spindle, surface grinding spindle, hydrostatic spindle and hydrodynamic spindles for center-less, deep hole, high frequency, internal, external, and surface grinding applications.We specialize in the remanufacture of low speed spindles, high load capacity turning spindles to high-speed precision grinding spindles and hydro-static spindles, hydro-matic spindles , ball bearing and air bearing equipment. Our thorough procedures for machine tool spindle failure analysis, spindle calibration, and spindle testing make us the ideal resource for the repair, reconditioning, or remanufacture of your machine tool grinding spindles.

GTI’s Spindle Service Process

  • High performance acoustic control sensors monitor acoustic emissions from your grinding spindles resulting in higher grinding accuracy, efficiency and reduced machine wear.
  • Dittel GAP-R GA: Reduces contact control unit measures structure-borne noise directly on the shaft of the grinding wheel (internal and external grinders) or dressing roller.
  • GAP 3000 and GAP 5000: Both are directly applicable to OD, ID and surface grinders and are used to control “GAP” eliminate, change feed rate as required, initiate dress feed or continue dress, and act as crash prevention. The GAP 5000 also incorporates an automatic wheel balancer.

We are a trusted sales and service representative for Walter Dittel GmbH, U.S. manufacturer of advanced integrated Acoustic Control Systems, Balance Control Systems and Process Control Systems precision grinding spindles and equipment.

We provide spindle service for the following Dittel Systems:

Dittel HBA 4000: a fully automatic balancing system, especially suitable for high speed, precision grinding.
Dittel HBA2000: is an electro-mechanical system with non-contact control, appropriate for larger grinding wheels.

  • Automatic vibration control and imbalance compensation after grinding and dressing processes
  • Balancing of grinding wheel, flange and drive system under production conditions
  • Increased safety
  • Longer machine service life
  • Quieter machine operation
  • Reduced need for adjustment of grinding wheel to work piece
  • Elimination of accidental contact between grinding wheel and work piece

Dittel 5000

  • Automatic balancing of grinding wheels during rotation
  • Automatic touch control dressing
  • Automatic signaling of Crash Control Logic
  • Reduced cost over two separate systems
  • Shorter cycle time due to “first touch” acoustic signal emission censoring
  • Universal system for all types of grinding spindles and machines
