Tolerance Workpiece rotating system Guide bush tolerance should be G6 in order to keep

Tool - fixed Guide bush Workpiece - rotating consistent tool life and cutting accuracy. Diameters
for G6 tolerance are shown on the right.

Cost efficient

Only used when the workpiece and the Hardened steel Workpiece rotating

(inexpensive) tool axis are on the same line. Tool rotating Long life

  • Better hole straightness and wear resistance on guide Tungsten carbide

Workpiece rotating guide bush bush are provided compared to the tool rotating system.

  • Keep the alignment between guide bush Guide bushing and spindle within 0.02 mm. (use hardened steel or carbide)

Coolant

Up toTemperature
0.02 mmThe proper coolant temperature is 30 - 40°C (90 - 100°F).

If the temperature exceeds this range, the coolant will deteriorate easily and may shorten

  • Can be used when the workpiece and the tool life and generate poor surface finish. tool axis are not on the same line.
  • Keep the alignment between guide bush Filtration and spindle within 0.02 mm. The coolant must be filtered properly in order to

protect guide pads and workpiece surface.

DTS

Positioning of outer tube and guide bushWater-soluble type
Be sure to set the outer tube more than 5.0 mm intoAround 10% (dilution rate 1/10) is recommended
the guide bush to properly supply the coolant.for the concentration of water-soluble

coolant in order to protect guide pads. Positioning of workpiece material and guide bush Sealing is not required for DTS because of the vacuum effect, but keep the gap between workpiece

material and guide bush within 1.0 mm. Workpiece Guide bush Outer tube
