Tool Test Results

This test was conducted in a Makino A55-E with the same program being ran in the exact same fixturing for each tool tested.  The Hanita Verimill ¼ dia and ½ dia tools were used in all holders.  We tested 3 types of precision tool holders and used a standard side lock holders as the control.  Material used was 303 SS.

Test goal:

The goal of the test was to find a tool holder to work in the high precision milling and drill situations in which we often face.  

What was tested:

Ease of use for personnel (shrink fit does not apply in test)
Run out in machine on flutes and shank
Cutter flex with light ruff passes for tool rigidity ½ dia.depth slot
Cutter flex with ruff pass 1 dia. depth slot
Cutter deviation on skim pass .0025 radial
Surface finish side milling
Suface finish endmilling


The tool holders tested were as follows:
  1. End Mill Adapter- ¼ dia. & ½ dia.
  2. Rego-Fix Power Grip
  3. HPI-Pioneer MX Collet Chuck
  4. Haimer Shrink fit ¼ dia. & ½ dia.
Note:
  1. The ½ dia. Shrink fit holder was extended length and did affect the results of test.
  2. HPI Pioneer MX was tested as a roughing tool when it is designed for finishing only.
  3. Shrinker and Power Grip require special equipment for tool change


Test 1. ¼ Diameter

Ease of Use:
  1. End Mill Adapter
  2. Rego-Fix Power Grip
  3. HPI-Pioneer MX Collet Chuck
  4. Haimer Shrink fit ¼ dia.
