GP SYSTEM (SINGAPORE) PTE LTD - ROHM [Product 1: Precision Short Drill Chucks]

Precision Short Drill Chucks for clockwise and anti-clockwise rotation. (High accurate concentricity <= 0.02mm)
Clamping and releasing of the tool: To ensure correct function of the short drill chuck, the following instructions should be followed:

	Clamping of the tool can only be made if the machine is stopped or away from the machine. The short drill chuck (item 1) is clamped from the side through a bevel gear by means of an allen key (item 3). Turn the allen key clock- wise to clamp the short drill chuck, to release anti-clockwise.
1. The gripping jaws must be opened to insert cutting tool (item 2). 2. The tools (item 2) must be inserted fully in the short drill chuck (item 1, picture 1). 3. Turn the allen key (item 3) clockwise to clamp the tool 15 Nm maximum (picture 2). 4. Check tool is clamped. Do not use taper shanks. 5. The short drill chuck is ready for operation and could be clamped in the machine main spindle (picture 2). 6. In order to release the tool turn the allen key anti-clockwise.

High precision and accurate concentricity. Secure gripping of the
tool through mechanical amplification of the clamping force. No
automatic slackening of the clamping force while machining with
either clockwise or counterclockwise rotation or on spindle stop.
Clamping and releasing effected by means of an allen wrench.
