ACCESSORIES & FIXTURES
- LM Linear Fixture Overview
- RM Rotary Fixture Overview
- RM Rotary Fixture Applications
LM Linear Fixture for the RG9
The LM is a linear motion axis with a position accuracy of 1µm.
It mounts directly onto the CNC fixture X axis of the RG9 giving you full CNC X and Y control of tool placement
- multiple grinding positions
- movement of the tool axis by up to 75mm
RM Rotary Fixture for the RG9
The RM is a CNC controlled, rotary fixture which replaces the normal tool post on an RG9 CNC grinding machine. The RM provides for:
- Coning via continuous rotation – under CNC control to produce cones or chamfers on tools, such as:
- drill studs
- golf-tee PcBN inserts - Indexing to a position accuracy of 1/2000th of a degree for manufacture of multiple tooth tools, such as end mills, reamers and spade drills
- Peripheral Grinding when used in conjunction with the TSU2
- Helical tools
- Stepped end mills
- Stepped reamers
K-Lands or PCD Chamfers
PcBN-tipped tools for hard turning generally need K-lands to be applied and in some situations, such as oil bit slugs, PCD may also need to be chamfered to strengthen the hard, brittle edge.
Using a RM rotary module, these operations can be achieved quickly and accurately.
- The chamfer is ground accurately relative to the top surface of the PcBN or PCD
- One corner-tipped indexable insert with a centre hole can easily be ground and chamfered.
