SPINJET_GREENLINE

New Generation SPINJET GREEN LINE
High Speed Compact Spindle
Replaces Existing SPINJET Spindles


Highlights
Following the success of SPINJET products - coolant driven high speed compact spindles for small diameter tools - ISCAR is introducing the SPINJET-GREEN LINE (TJS GJET) family of high speed spindles. The new family is a step ahead in developing advanced small-sized spindles operated by the coolant supply system of a machine tool.


Features
  • A broad range of output rotational speed: 35000-55000 rpm
  • A new improved bearing system:
    • New bearing system design
    • Increased number of bearings: 3 bearings inside vs. 2 in SPINJET TJS 20K, 30K and 40K spindles
    • New bearing seal
    • New bearing lubricant featuring greater viscosity and additive agents
  • A new shaft lock mechanism

Due to the new design features, SPINJET-GREEN LINE spindles ensure the following advantages:
  • Rotational speed range meets most required values
  • Bearing system design minimizes risk of overload and fluid penetration to considerably increase spindle reliability, resulting in significantly improved tool life
  • New shaft lock mechanism enables a simple and secure way of mounting a cutting tool in the spindle

General Data
Operating Data Model: SPINJET-GREEN LINE
Operating range of coolant pressure [PSI] 290-580 [20-40 bar]
Operating range of coolant flow rate [gal/min] 2.64-5.28 [10-20 l/min]
Rotational spindle speed [rpm]* 35000- 55000
Optimum cutting tool diameter [inch] Drilling: .0196”-.157” [0.5-4 mm]
Milling : .0039”-.138” [1-3.5 mm]
Maximum tool shank diameter [inch] .275” [7 mm]

Notes
  • Rotational spindle speed is based on coolant pressure and flow rate
  • Coolant pressure is measured from the spindle inlet


Strategic Advantages:
Cutting Tools:

  • Small cutting tools (dia. .0196-.157 inch [0.5-4 mm])
  • Small cutting tools at high speeds enable precision while reducing tool wear

Applications
  • Milling, drilling, thread milling, engraving, chamfering, deburring, fine radial grinding
  • Operation: Finishing and semi-finishing operations

Flexibilities:
  • CNC machines: milling centers / turning / turn mills / tap mills
  • Suitable for most adaptor types + lathe turret mounting

Economical Advantages
  • Upgrades existing CNC machine to a high speed milling (HSM) performer at a fraction of the cost of dedicated high speed machines
  • Boosts productivity - shortens production time and cuts costs
  • Quick ROI
  • Simple and easy to integrate - no pre-installation or external feed lines
  • Compact – no size restriction due to added parts or power feeds, fits ATC or turret
  • Cuts utility costs such as compressed air and electricity
  • Uses the machine’s own coolant as a pressurized power source

Industrial Sectors
  • Serves important industries worldwide:
    • Die & Mold
    • Medical
    • Energy
    • Automotive
    • Aero space
    • 3D Printing
    • General Industry

Machine tool requirements for using SPINJET-GREEN LINE spindles
  1. Coolant flow through the machine spindle
  2. Min. coolant pressure at the spindle outlet: 290 psi (20 bar).
  3. Max. coolant pressure at the spindle outlet: 580 psi (40 bar).
  4. Min. flow rate: 3.17 gal/min. (12 l/min).
  5. Coolant filtration level: max. 3940 μinch.

Operating Tips
  1. When operating the SPINJET-GREEN LINE spindles, monitoring rotational speed is critical. A correctly set rotational speed ensures optimal machining conditions and avoids damaging the spindle.
  2. Cutting speed depends on workpiece material and its hardness, the shape of a machined surface, a machining strategy and cutting tool geometry. Refer to cutting tool manufacturer’s documentation.
  3. Dramatic fluctuations of the rotational speed (rpm) operation can indicate problems such as an inadequate coolant pressure or a broken cutting tool.

Using Precision ER11 Collets
When using ER11 spring collets, it is recommended to use only high quality precise collets that are engineered for maximum accuracy and tool life.

To maximize SPINJET-GREEN LINE spindle tool life, we recommend following the “10% rule”:

The working rotational speed (rpm) should drop by up to 10% of the rotational speed (rpm), which is registered at ‘idle speed’.

Keeping this rule ensures reducing axial and radial load on the internal mechanism.

To register idle rotational speed:
  1. Install the SPINJET-GREEN LINE spindle carrying a cutting tool into the machine.
  2. Start the spindle rotation by turning on the fluid supply at required pressure and find the idle RPM speed by reading the display monitor of the spindle.

General instructions for storage:
The SPINJET-GREEN LINE spindles do not require specific periodic maintenance; however the following instructions should be followed before storing a spindle:
  1. Clean the spindle by air blowing for 10-15 seconds.
  2. Max. air pressure for cleaning is 30 psi (2 bar). The rotational speed during cleaning must not exceed 50000 rpm.
  3. After cleaning, disconnect the spindle from the display device.
  4. Place the spindle in its original packaging box and store it in the appropriate place.
