Introduction
The TS27R probe is used for tool setting on CNC machining centres.
For tool length measurements and broken tool detection, the tool is driven against the probe’s stylus in the Z axis. Rotating tools can be set in the X and Y axes for tool radius offsets.
Screw adjusters allow the stylus to be aligned with the machine’s axes.
An interface unit processes signals between the probe and the CNC control.
Operation 1-7
Achievable set-up tolerances
The tolerances to which tools can be set depend upon the flatness and parallelism of the stylus tip setting. A value of 5 µm (0.0002 in) front to back and side to side is easily achievable over the flat portion of the stylus tip, and 5 µm (0.0002 in) parallelism is easily achievable with the axes of a square tip stylus. This setting accuracy is sufficient for the majority of tool setting applications.
The surface cutting speed is not maintained if cutters smaller than Ø24 mm (Ø0.95) or larger than Ø127 mm (Ø5.0 in) are used.
First touch – machine feedrate
The feedrate (f) is calculated as follows: f = 0.16 × rev/min f units mm/min (diameter set) f = 0.12 × rev/min f units mm/min (length set)
Recommended rotating tool feedrates Second touch – machine feedrate
Cutters should be rotated in reverse to the cutting direction.
800 rev/min, 4 mm/min (0.16 in/min) feedrate.
Software routines
First touch – machine spindle rev/min
Rev/min for the first move against the probe stylus is calculated from a surface cutting speed of
60 m/min (197 ft/min).
Spindle speed should be maintained within the range 150 rev/min to 800 rev/min and relates to cutters of Ø24 mm to Ø127 mm (Ø0.95 in to
Ø5.0 in).
Software routines for tool setting are available from Renishaw for various machine controllers and are described in data sheet H-2000-2289.

Note 1
Note 2
Note 3
Performance specification is tested at a standard test velocity of 480 mm/min (18.9 in/min) with a 35 mm stylus. Significantly higher velocity is possible depending on application requirements.
Trigger force, which is critical in some applications, is the force exerted on the component by the stylus when the probe triggers. The maximum force applied will occur after the trigger point i.e. overtravel. The force value depends on related variables including measuring speed and machine deceleration. Trigger force is measured with a 50 mm (1.97 in) stylus.
These are the factory settings, manual adjustment is not possible.
NOTE: For stylus recommendations, please refer to the Styli and accessories technical specification
(H-1000-3200).

Spirol® pins, drill two holes in the machine table
Conduit
1-12 Installation (continued)
Conduit for cable protection
Renishaw recommends that Thomas and Betts
Type EF conduit, or a suitable alternative, is fitted to all installations. The TS27R conduit adaptor accepts Ø11 mm (0.43 in) flexible conduit.
NOTE: The cable screen is connected to the machine via a 100 nF capacitor inside the TS27R to prevent possible earth loops. Ensure the cable screen is connected to the appropriate input on the interface. The MI 8-4 interface is fully described in user’s guide H-2000-5008. The alternative
HSI interface is fully described in user’s guide
H-5500-8554.
The interface also includes an ‘inhibit’ function, as well as a facility for simple selection between the tool setting probe and an inspection probe.
The HSI interface is used with the standard G31
SKIP type control probe input. Probe status output is a voltage-free SSR (solid state relay) which can be connected as normally open (N/O) or normally closed (N/C).
Maximum current 50 mA peak
Maximum voltage ±50 V peak
An inhibit function is included, and a facility to drive an external probe status LED.
Interfaces
The MI 8-4 interface is used with the standard
G31 SKIP type control probe input. The probe’s status output operates between 4.75 Vdc and
30 Vdc.
All inputs are fully configurable for ACTIVE HIGH and ACTIVE LOW operation.

The top surface of the stylus must be set level, front to back and side to side.
The front to back stylus level is obtained by alternately adjusting screws L1 and L2, which causes the probe cable end to rise or lower, changing the stylus level setting. When a level stylus surface is obtained, tighten screws L1 and L2.
Side to side level is obtained by alternately adjusting grubscrews L3 and L4, which causes the probe module to rotate and change the stylus level setting. When a level stylus surface is obtained, tighten screws L3 and L4.

Stylus level setting is the same for disc and square styli. In addition, square styli side faces can be aligned with the machine’s X/Y axes.
Coarse rotational adjustment is obtained by slackening the stylus holder grubscrew A (see page 1-16), rotating the stylus in its holder, then retightening grubscrew A. (Always use the support bar – see page 1-17.)
Fine rotational adjustment is obtained by loosening the four grubscrews R1 and alternately adjusting the two probe rotational adjuster screws R2 and R3 until the required tip parallelism to the axes is achieved. Retighten grubscrews
R1, R2 and R3.

1-20 Service and Maintenance
Service
You may undertake the maintenance routines described in this handbook.
Further dismantling and repair of Renishaw equipment is a highly specialised operation, which must be carried out at authorised Renishaw service centres.
Equipment requiring repair, overhaul or attention under warranty should be returned to your supplier.
Probe serial No
O ring
Spring
Front cover
Metal eyelid seal
Inner diaphragm seal
Maintenance
The probe is a precision tool and must be handled with care.
Ensure the probe is firmly secured to its mounting.
The probe requires minimal maintenance as it is designed to operate as a permanent fixture on
CNC machining centres, where it is subject to a hot chip and coolant environment.
1. Do not allow excessive waste material to build up around the probe.
2. Keep all electrical connections clean.
3. The probe mechanism is protected by an outer metal eyelid seal and an inner flexible diaphragm seal.
Approximately once a month, inspect the probe inner diaphragm seal. If it is pierced or damaged, return the probe to your supplier for repair.
The service interval may be extended or reduced depending on environment and operating conditions.

1. Remove the stylus and holder (see page 1-17).
2. Remove the break stem using the 5 mm AF spanner.
3. Use a C spanner to remove the probe’s front cover. This will expose the metal eyelid seal and the inner diaphragm seal. Remove the metal eyelid and spring. CAUTION – these may fall out.
4. Wash inside the probe, using clean coolant.
(DO NOT use sharp metal objects to clean out debris.)
5. Inspect the diaphragm seal for signs of piercing or damage. In the event of damage, return the probe to your supplier for repair, as coolant entering the probe mechanism could cause the probe to fail.
6. Refit the spring and metal eyelid (the spring’s widest diameter is against the metal eyelid).
7. Refit the remaining components (see pages
1-16 and 1-17).
