Flat Face
1. Due to good chip control, peck drilling is not necessary for soft steel like 1015.
2. When machining 304, for hole depths of more than 2.5D, utilize the step machining process.
3. In order to have smooth chip removal, we recommend internal coolant.
Technical 1. Fix stacked plates securely to ensure they do not slip while machining.
Information
Stacked Plates
1. If the overlap amount is less than 1/3 x D, machining is possible.
Drilling Hole Expansion
1. When machining concave holes set the feed rates at half or less than continuous hole machining.
Concave Surface
Pipe Material 1. Hole machining above the centerline of the pipe is possible.
2. Do not machine on curved surface areas.
P recautions for Use 2) If drill is rotating
Core Deviation
1) If drill is stationary
