The VELOX MASTER 4M/22 is an automatic straight-line edger designed for glass working, manufactured by Zafferani Glas S.R.L. in Italy. This machine is equipped with an inverter system that allows for precise adjustment of the track speed, making it suitable for processing various glass thicknesses.
Function Description:
The primary function of the VELOX MASTER 4M/22 is to automatically edge glass sheets in a straight line. It uses a series of diamond and polishing wheels to achieve different types of edges, including round, flat with arrises, and 45° bevels. The machine's track system, driven by a motor-reducer, transports the glass through the grinding and polishing stages. The inverter system allows the operator to adjust the speed of the track based on the glass thickness, ensuring optimal processing results.

Usage Features:
Before operation, proper installation and electrical connections are crucial. The machine should be positioned on a level surface, allowing sufficient space for maintenance. Electrical connections must match the factory's voltage, and the machine must be properly earthed.
Adjustment of the Machine:
- Pre-operation Check: Ensure all parts, including the transport bench, are in place. Verify that the spy light is on and that the motors of the wheels (not the track) rotate correctly. If rotation is wrong, invert the general electric cables (R-S-T). Ensure the water in the external sink is at the correct level and that water is pumped to the wheels. If using direct water, ensure sufficient supply.
- Thickness Adjustment: Use the handle-wheel (10) to adjust the track according to the desired glass thickness. Adjust all pointers (3) and (4) of the diamond and polishing wheels to match the thickness.
- Wheel Engagement: Lower all wheels using handle-wheel (5). Start the machine with a glass inside and slowly raise the wheels with handle (5) until they touch the glass.
- Centering and Tilting: The handle-wheels (3) for centering and (4) for tilting the wheels provide an approximate direction. Fine-tune these adjustments after processing the first glass to ensure proper alignment and absorption, as indicated by the ammeters.
Adjustment of Track-Speed:
The VELOX MASTER 4M/22 features an inverter system to adjust track speed via a potentiometer on the electric board. The recommended speed settings vary with glass thickness:
- 3-4 mm: 2.3 m/min (POTEZ. SETTING 4-5)
- 5-6 mm: 1.5 m/min (POTEZ. SETTING 3)
- 8 mm: 1.2 m/min (POTEZ. SETTING 2-3)
- 10-12 mm: 1.0 m/min (POTEZ. SETTING 2)
- 16 mm: 0.6 m/min (POTEZ. SETTING 1)
- 22 mm: 0.5 m/min (POTEZ. SETTING 0)
These values are indicative and may need adjustment based on various influencing factors.
Glass Section Types:
The machine can work with different glass sections using various wheels available on the market:
- ROUND (3-12 mm): D.WHEEL 175, ROUND 14, POLISH 200X20X90
- ROUND (13-22 mm): D.WHEEL 175, ROUND 24, POLISH 200X30X90
- FLAT+ARRISES (3-12 mm): D.WHEEL 175, FLAT 10, POLISH 200X20X90
- FLAT+ARRISES (13-22 mm): D.WHEEL 175, FLAT 20, POLISH 200X40X90
- 45° (6-12 mm): D.WHEEL 195 (Polishing not suggested for this type)
Maintenance Features:
Regular maintenance is essential for optimal performance and longevity of the machine.
- Water Tank Cleaning: The water tank (43), where the pump (13) is located, should be changed daily to ensure clean water. Weekly, run the machine for ten minutes without glass and with clean water to clear silicon residues from the circuits.
- Polishing Wheel Refrigeration: For good polishing, refrigerate the polishing wheels with running water by connecting valve (97) directly to the hydric network.
- Track Lubrication: Periodically lubricate the track using the grease pump (92). Actuating the pump lever 5-6 times while the track is working will reduce fretting of the track guides.
- Rubber Plate Adjustment: If the rubber plate for chaintrack traction does not press the glass correctly due to mechanical issues, adjust the hand-wheel (1) for proper pressure and move the red index to indicate the exact glass thickness.
- Track Alignment: If plate glass longer than 1.5 meters is not worked correctly after several months, open the track carters, slacken the grub screw on the collet of the pinions, slacken the jam nuts, and lightly screw screw (16) by 1/4 turn from both sides of the track. Then lock everything. This adjustment helps restore equilibrium to the chain conveyor.
- Track Gear Lubrication: Periodically check and lubricate the track gears (30), (31), (32) with grease.
- Wheel Installation: When installing wheels, ensure the motor shaft and wheels are clean to ensure proper centering.
- Wheel Consumption: To ensure even wear, invert the wheels after prolonged use. Check if the wheels have round or flat edges and adjust their position using handle-wheel (3) if necessary.
All ZAFFERANI machines are factory tested and checked, making their adjustment relatively simple. For quick dispatch of spare parts, it is necessary to provide the type of machine and voltage, serial number of the machine, number of the spare part, and the quantity needed.
