Gun Feeder: Small-diameter, Deep Hole Gun Drilling Machine

High-precision gun drilling machine specializing in small-diameter and deep holes!
The "Gun Feeder" is a high-precision, high-efficiency gun drilling machine developed exclusively for small-diameter and deep holes.
It is optimized for drilling small-diameter and deep holes used in applications like fuel injection nozzles, sleeve pins for molds, and parts for hydraulic machines.

Features

High-precision Drilling

　　 This short length gun drill can be used with Sugino's special whip guide system (slide type). 　　
　　 This allows it to control vibration and the drill with high precision.
　　 Also, it is possible to start drilling very slowly to control hole curvature.

Outstanding Performance

　　 A numeric keypad can be used to easily enter data required for gun drilling.
　　 Also, the values input for e.g. rotation speed and feed rate can be checked on a single screen.

Both a two-spindle model and a single-spindle model are available.

　　 The two-spindle model optimized for drilling holes of different sizes and increasing productivity, and the single-spindle model equipped with a workpiece rotation unit are offered.

Notes:
1. Specifications other than the above are optional. Please refer to the catalogs for further details or contact your
nearest office.
2. The drilling depth varies according to the gun drill length used. A whip guide is provided at one location with the standard gun drill. Depending on the gun drill used, whip guides at two or three locations (optional) may be required.
3. The maximum working pressure of the high pressure pump is 11 MPa (when the viscosity is 10 mm2/s(cSt)). However, the pressure and flow vary with the viscosity of the fluid, and the diameter and length of the gun drill used.
4. Standard coating color / mount: Dark gray (Munsell N3.0), splash guard: White. Front door: Metallic blue
