RTP20 indexing head

RTP20 indexing head with integral TP20 touch-trigger probe

  • RTP202-axis head with 168 repeatable positions in 15 degree increments
  • Indexing can be manual or automatic using the CMM motion
  • TP20 module compatibility provides a wide range of force and length options to optimise machine performance and access capability
  • Repeatable TP20 stylus module changing in each pre-qualified position without the need for re-qualification significantly enhances productivity
  • Compatible with full range of TP20 stylus modules
  • Modules can be changed manually or automatically with the MCR20 module change rack
  • A built-in extension, together with existing extension bars, allow reach up to 168 mm (including maximum stylus length)

RTP20 kit part number construction

The following example explains how to construct an RTP20 kit part number.

If a customer required an RTP20 kit containing the following: 1 × low force module, 1 × standard force module, MS1 (S) shank and a M10 pole base. The part number would be constructed as follows in the form A-5400-XYOZ.

To select X...


ModuleType

X = 1

A-1371-0392

Low force mod

X = 2

A-1371-0270

Std force mod

X = 3

A-1371-0271

Med force mod

X = 4

A-1371-0272

Ext force mod

X = 5

A-1371-0419

6-way mod

X = 6

A-1371-0430

EM1

X = 7

A-1371-0431

EM2

X = 8

No rack


For a low force module X = 1 therefore A-5400-1YOZ.

To select Y...


ModuleType
Y = 1

A-1371-0392

Low force mod

Y = 2

A-1371-0270

Std force mod

Y = 3

A-1371-0271

Med force mod

Y = 4

A-1371-0272

Ext force mod

Y = 5

A-1371-0419

6-way mod

Y = 6

A-1371-0430

EM1

Y = 7

A-1371-0431

EM2


For a standard force module Y = 2 therefore A-5400-12OZ.

To select OZ...


ShankDescription

OZ = 1

M-1041-2146

MS1 shank

OZ = 2

M-1041-1650

MS2 shank

OZ = 3

M-1041-1656

MS3 shank

OZ = 4

M-1041-1658

MS4 shank

OZ = 5

M-1041-1652

MS5 shank

OZ = 6

M-1041-1653

MS6 shank

OZ = 7

M-1041-1654

MS7 shank

OZ = 8

M-1041-1657

MS8 shank

OZ = 9

M-1041-4843

MS9 shank

OZ = 10

M-1041-7507

MS10 shank

OZ = 11

M-1041-1088

MS11 shank

OZ = 12

M-1041-7068

MS12 shank

OZ = 13

M-1041-5348

MS13 shank

OZ = 14

M-1041-5981

MS14 shank

OZ = 15

M-1041-2153

MS15 shank

OZ = 16

M-1041-7132

MS7(S) shank

OZ = 17

M-1041-7113

MS17 shank

OZ = 18

M-1041-7114

MS1(S) shank

OZ = 19

No shank


For an MS1(S) shank OZ = 18 therefore A-5400-1218.


Pole studDescription

OZ + 0

A-5400-0121

M8 pole base

OZ + 20

A-5400-0122

M6 pole base

OZ + 40

A-5400-0123

5-15 pole base

OZ + 60

A-5400-0124

3/8 pole base

OZ + 80

A-5400-0125

M10 pole base


Finally, the M10 pole base requires an addition of 80 to be made to OZ, the final part number is...

A-5400-1298
