STANDARD EXPANDING MANDRELS

Mandrins expansibles standards Tobler TEP

TEP

EXPANDING MANDRELS BETWEEN CENTERS MOUNTING

Accuracy: Runout ≤ 10µ
Quick change of the sleeve – Easy assembly. The most commonly used sizes of TEP mandrel have been brought together in a set of two types, which are provided in a robust toolbox to protect them.

The two types of TEP arbor and expanding sleeve set can accommodate workpiece diameters from 12 to 55 mm

APPLICATION

  • Turning, grinding, and inspection

TECHNICAL FEATURES

  • TEP-A – Workpieces range: 12 – 25 mm
  • TEP-B – Workpieces range: 25 – 55 mm
  • Actuation: Manual
  • To cover the whole diameter range, sleeves TEP280-8 and TEP380-9 will be required or for occasional use only, use the TEP250-8 and TEP350-9 sleeves fully expanded.

ADVANTAGES
It is take for granted that every workstation where inspection and grinding takes place has a set of angle gauges and other measuring equipments but it should be equally obvious also to equip each such station with sets of TEP mandrels.
Their versatility, reliability and precision make them an indispensible tool for inspection and grinding operations between centers.
