Phoenix Series, Indexable End Mill, 3-Flute, Corner Radius Shape, PXM PXDR

Product features and specifications

Basic specifications and features of the product

• For narrow pocket processing and groove machining
  By using coolant and air from the inside, it prevents cutting chips from getting caught. Improves cutting chip discharge.

Performance/test information

[PXDR-P]Achieves stable machining even with L/D = 7, which is easy to chatter

PXDR-P has less chatter than other manufacturers' products, and a good machined surface was obtained even in the corners.

Usage method and usage examples

Usage method

"Tightening procedure"

(1) Cleaning

Remove dust and dirt from the head and shank fastening

(2) Temporary tightening

Hand tightening

(3) Final tightening

Tighten with a dedicated wrench

(4) Confirmation

Confirm that there are no gaps

Recommended cutting conditions

Recommended cutting condition table

PXDR-P L/D≦5

PXDR-N L/D≦5

Precautions for cutting conditions

• (1) Use machines and holders that are rigid and highly accurate.
• (2) Adjust the rotational speed and feed speed according to the usage conditions such as cutting depth and mechanical rigidity.
• (3) If the amount of protrusion is long, chattering is likely to occur, so adjust the rotational speed, feed speed, and cutting depth.
• (4) The cutting conditions should be selected in consideration of the protrusion length of the shank holder (PXMZ) from the end face of the holder plus the overall length of the head (LF).

Cautions/prohibitions

• Please use the PXM dedicated spanner when attaching the head (commercially available spanners cannot be used).
• Tighten until the end faces of the head and shank holder are attached. Please make sure there are no gaps.
• If you degrease the fastening part, the tightening will become stiff and the end face may not be attached. Please do not degrease.
• Insert the spanner according to the notch in the head, and slowly rotate it in the direction of rotation.
