Flange Facing SX2872

Introducing the Silk SX2872, a lightweight, portable flange facing, grooving, and weld preparation machine. Designed for full-faced, raised face, and grooved flanges, the SX2872 operates within a diameter range of 711mm to 1829mm (28’’ to 72’’), making it versatile for various industrial applications.

Key Features:

• Wide Application Range: Ideal for tube sheet machining, recessed gasket grooves, and hub profiles.
• Extra Reach Tool Post (Optional): Enhances the machine’s versatility for different tasks.
• High-Quality Construction: Built from premium materials for durability and precision, ensuring machine shop accuracy with portability.
• Efficient Power Transmission: Spur gears directly engage the drive ring, minimising power losses and maximising torque at the cutting tool.
• Flexible Operation: Can be used horizontally, vertically, or overhead.

Mounting Base:

• Design: The mounting base assembly allows installation in the centre of any flange within the machine’s diameter range.
• Components: Includes a cruciform body with four adjustable clamping jaw assemblies.
• Function: Ensures secure installation and alignment before turntable setup.

Turntable Assembly:

• Support: Rigid support for air motors, gearbox, and surfacing arm assembly.
• Rotation: Upper part provides rotational movement for surfacing, while the lower part remains stationary, held by the mounting base.

Drive Arrangement:

• Motors: Driven by two pneumatic motor units mounted directly into the ring gear, balancing torque and acting as a backlash eliminator and cushion drive.

Feed Gearbox:

• Mounting: Positioned on the turntable assembly.
• Functions: Offers various cutting feeds selectable by a push/pull selector and enables manual positioning of the toolpost.

Cutting Arm Assembly:

• Mounting: Positioned on the turntable assembly.
• Feed: In/out feed provided by a lead screw driven by the gearbox.
• Cutting Depth: Achieves cuts up to 2mm (0.079’’) without flange holes and 0.5mm (0.02’’) with flange holes.
