The BCAMCNC BCSJBW-1800 UPVC Glazing Bead Cutting Saw is designed for accurate cutting of the PVC and UPVC glazing bead profiles used to secure glass inside window and door frames. It performs 45° cutting and glazing-bead foot milling while processing two profiles simultaneously.
Pneumatic clamping, adjustable pressure plates and a fine-adjustable positioning system help produce consistent profile lengths and tighter corner joints. The machine is suitable for UPVC window manufacturers that require efficient glazing bead preparation before final glass assembly.
A glazing bead is the narrow PVC or UPVC profile installed around the glass after the glass panel is placed inside a window frame or sash. It holds the glass in position, works with the sealing gasket and covers the installation gap around the glass.
The BCSJBW-1800 cuts glazing beads to the required length and forms accurate 45° ends so that four bead profiles can fit together around the glass. Its additional foot-milling function processes the locating or hook section of the glazing bead to support easier installation and cleaner corner assembly.
This machine cuts glazing bead profiles rather than glass. It is also different from a conventional double-head cutting saw, which is mainly used to cut the larger profiles used for window frames, sashes, mullions and door structures.
Pneumatic profile clamping system
Multiple pneumatic cylinders press the glazing bead profiles against the positioning fixture before cutting. The soft contact pads hold the narrow profiles securely while reducing the risk of scratches or pressure marks.
Stable pneumatic clamping prevents profile movement and vibration during sawing. This contributes to more consistent cutting lengths, cleaner edges and accurate 45° angles.
The clamping layout supports the simultaneous processing of two glazing bead profiles, helping manufacturers increase output without repeatedly loading and positioning individual pieces.
Adjustable glazing bead positioning fixture
The profile support table and positioning fixture keep each glazing bead at the correct height, direction and cutting position. The machined slots provide stable support for narrow PVC and UPVC profiles.
The adjustable pressure plate allows the machine to accommodate different glazing bead cross-sections. When changing between compatible profiles, operators can adjust the fixture instead of replacing the complete pressure plate, reducing setup time and tooling investment.
A horizontal fine-adjustment mechanism on the positioning plate helps operators correct the cutting position. Proper adjustment improves the fit of the glazing beads and reduces visible gaps at the assembled inner corners.
Multi-blade cutting and milling system
The saw blade unit performs the main 45° cut and the required milling of the glazing bead locating foot. Cutting and foot processing in one operating cycle reduces separate machining steps.
The dual-motor configuration provides a total power of 2.2kW. With a spindle speed of 2800 r/min, the cutting system is designed to produce smooth and consistent edges on PVC and UPVC glazing bead profiles.
Accurate blade positioning helps produce a cleaner corner fit and reduces the need for manual correction during glazing bead installation.
Air filter and pressure regulator
The pneumatic air filter and pressure regulator prepare the compressed air used by the clamping and feeding systems. The filter helps remove moisture and contaminants, while the regulator controls the working pressure.
A visible pressure gauge allows the operator to monitor the air supply in real time. Stable air pressure helps maintain consistent clamping force and reduces problems caused by insufficient or excessive pressure.
Filtering the compressed air also protects pneumatic cylinders, solenoid valves and air lines, contributing to longer component life and more reliable daily operation.
Compressed-air cleaning gun
The machine is equipped with a compressed-air cleaning gun for removing PVC chips and cutting residue from the blade area, positioning fixture and worktable.
Regular cleaning prevents chips from accumulating inside the positioning slots or around the blades. A clean working area supports accurate profile positioning and simplifies daily machine maintenance.
Accurate 45° cutting
The machine produces the 45° mitre cuts required for assembling glazing beads around the glass. Accurate cutting helps the four bead profiles form tighter and cleaner corner joints.
Simultaneous cutting of two profiles
Two glazing bead profiles can be positioned and processed in one cycle. This improves production efficiency and reduces repeated loading operations.
Integrated foot milling
In addition to the main 45° cut, the blade system processes the locating foot or hook section of the glazing bead. Combining the operations helps simplify the preparation process.
Adjustable pressure plates
The adjustable pressure-plate design supports different compatible glazing bead profiles without requiring the complete clamping plate to be replaced for every profile change.
Horizontal fine adjustment
The positioning plate includes a horizontal micro-adjustment mechanism. Operators can fine-tune the cutting position to improve dimensional accuracy and corner fit.
Pneumatic profile clamping
Pneumatic cylinders automatically hold the profiles during cutting. Stable clamping reduces profile movement, vibration and inconsistent cutting results.
Compact machine body
The self-contained machine body requires relatively little workshop space. The external measuring and positioning ruler can be arranged according to the production layout.
Protected cutting area
The enclosed machine housing limits direct access to the rotating blades and helps contain PVC chips generated during cutting.
1. Measure the required glazing bead length
Measure the internal glass opening or use the finished window dimensions to determine the required glazing bead length.
2. Adjust the positioning system
Set the positioning ruler and fine-adjustment plate according to the required finished length. Confirm the cutting allowance based on the glazing bead profile.
3. Place the glazing beads
Position one or two PVC/UPVC glazing bead profiles inside the dedicated support fixture. Make sure the profiles are correctly seated against the positioning surfaces.
4. Clamp the profiles
Activate the pneumatic clamping system. The cylinders press the glazing beads against the fixture and prevent movement during cutting.
5. Complete cutting and foot milling
The saw blade unit cuts the profiles at the required 45° angle and processes the locating-foot section according to the installed tooling.
6. Release and inspect
After the blades retract, release the pneumatic clamps and remove the finished glazing beads. Check the cut surfaces, length and corner angle before installation.
7. Install the glazing beads
Place the prepared beads around the glass and press them into the window frame or sash groove. Accurately cut 45° ends help form tighter corner joints.
