Personal Attire Safety

- Always wear safety glass in shop.  (ANSI approved)
- Avoid loose clothing
- Gloves
- Watches
- Rings
- Use legs, not back for lifting
- Wear work shoes (leather)

Shop Environment Safety

- Keep floor free from oil and grease
- Remove chips from the floor
- Keep materials and tooling off floor.

CNC Machine Tool Safety

- Secure all adjusting keys and wrenches before machining
- Check all oil levels
- Back or side of machine tool
- Use only recommended accessories
- If you are working on a machine tool make sure you use the lock out tag out practices
- Be mindful of obstructions and sharp edges around the work area.
Machining Practices Safety

- In case of emergency, hit EMERGENCY STOP button
- Prior to its operation, check for obstacles in the working area.
- Check length of tools to prevent collisions with work
- Use correct speeds and feeds
- Check program on graphs first
- Always deburr part before and after machining
- Climb milling is preferred
- Mill as close to the work holding device

HA5C Indexer Safety
- Always check your programs rapid moves
Watch for rapid moves into the indexer

- Always check on the wiring to the indexer
Make sure the cutter stays away from the wiring

- Watch for tool chager clearances
Tools may “Z” down when making a tool change
Always position the indexer to the far right position

- Tool-holder clearances next to the indexer.

Make sure that the collet holder tooling will not interfere with the indexer
- One of the one main safety concerns is having enough clearance between the CAT40 tool holders and the indexer as the picture shows below.
