TSm v9

User Guide

info_outline
This User Guide applies to the currently released TSM v9 model. For earlier versions, the User Guide can be found at the corresponding links in the Archive.

Purpose

The TSm sensor is used to determine tool height and diameter. CNC milling machine generates coordinates when the tool touches the TSm measurement pad and uses them to calculate the height and diameter of the tool. The device can be used with various CNC systems: LinuxCNC, Mach3, embedded systems on industrial machines, etc.

TSm v9 main features

  1. Unidirectional repeatability 0.001 mm.
  2. Tungsten carbide pin-ball contacts.
  3. Over travel limit 7mm.
  4. Measuring tool length and diameter.
  5. The tool setter is equipped with both NPN-NC and PNP-NC output types.
  6. Protection against short circuits of the output to power or ground, from power reversal, splash protection.

Installation

info_outline
Placement TSm is recommended to be chosen so that the entire surface of the ceramic platform of the device is in the working area of the machine, with an indent from the boundaries = the maximum diameter of the tool being measured + 2mm.

The device is fixed to the machine body with three M3 screws. Three threaded holes are prefabricated in the machine body: tsm_v9_base

Adjustment

Before starting the measurement, it is necessary to adjust the device. As a result of the adjustment, the surface of the measuring platform should become parallel to the XY plane.

info_outline
The indicator should be sensitive to a weak effect of 0.3-0.5N (for example, most lever indicators have this property).

For adjustment, three points are selected at the measuring pad approximately at the edge of the site in the direction of the adjustment holes. The stylus of the indicator is located to measure the deviations in height. The results of the indicator must have to the same values ​​in these three selected points. For adjustment, a 2mm hex key is used from the kit, both screwing in and loosening of the adjustment screws located inside the holes, closed with elastic bands. The key is recommended to hold for a short lever, so as not to develop excessive force when screwing.
