HMT-20
OVERVIEW
HMT-20 Marking Tool
HMT20 Hydraulic marking Tool is a pressured coolant activated marking tool.
It can be used on machining centers or automatic lathes.
Minimum 15 Bar coolant pressure is required.
With pressure adjustment mechanism, suitable for 15-80 Bar machines.
Suitable for marking hard workpieces up to 60-62HRc.
Can be used on rough surface marking with the help of distance compensation mechanism. (4mm distance comp.)
Almost wear-free carbide marking needle.
Can be used at low rpm if machine doesn’t support non rotating axis movement.
Simple usage and no installation.
20mm standart Weldon shank.
HMT type tools are activated with pressured coolant. For the first trials the marking needle should be positioned 6mm away from the workpiece surface which will be marked. When the interior cooling is activated, let the marking program run in basic setting the first time. No marking should be visible yet!
If the marking is already visible the coolant pressure should be reduced.
After adjusting the cooling pressure advance the marking needle 0.5mm closer towards the workpiece (5,5mm total dist). And run the program second time.
If no marking is detected advance again 0.5mm towards the workpiece and run the marking cycle.
Repeat these steps with 0.5mm increments until marking is visible.
Advance extra 0.5mm to ensure marking is complete and well formed.
Minumum marking position is 1mm to the workpiece surface. If no marking is seen at 1mm, stop the application and increase the coolant pressure of the machine or readjust pressure on the tool.
While approaching to the workpiece, marking needle hits the first dot multiple times and makes the entrance of the first character deeper. After determining the correct marking position aprroaching towards the marking position should be as fast as possible to minimize this.
