ALPHA HAND POLISHING SYSTEM The Alpha Wet Polishing System offers high quality, hand held, water-fed power tools to cover most common hand polishing applications in the stone and tile industries. High gloss polishes are easily achieved while reducing harmful dust and increasing safety.
ALPHA RIGID BACKER PADS Alpha Professional Tools first introduced rubber backer pads with the AEP-458 electric polisher to promote the concept of wet polishing, which became the accepted method of polishing. Alpha recognized the need to add a rigid version of this backer pad to its product line for the straight edge or flat surface polishing applications. We realized that Ceramica, with a flexible backer pad, was too flexible for these applications and produced wavy finishes.
ALPHA TWISTOUCH SYSTEM The New Alpha Twistouch System is a safe and long lasting polishing system that is quick and easy to use. The Twistouch System will increase performance and improve productivity, saving you time and money. The Twistouch Adapter is specially designed to accept Twistouch Turbo and Twistouch Backer Pads, which accept velcroTM backed accessories. The Alpha Twistouch System has everything necessary for all of your hand held polishing needs.
ALPHA CERAMICA THREE PART SYSTEM Alpha Ceramica is a three part system for polishing granite, hard marble and porcelain ceramics. Utilizing the best grade industrial diamonds and the best bond materials, Alpha Ceramica is sure to provide the best possible finish on your polished stone. Part 1: Ceramica Vitrified and Ceramica Metal • Long lasting and aggressive design. • Rigid or flexible depending upon application requirements.
ALPHA TWISTOUCH TURBO New Alpha Twistouch Turbo works as part of the Alpha Twistouch System that replaces Alpha Turbo. The Alpha “Original” Turbo discs were a result of many years of research for a series of diamond grits specifically designed to polish flat granite areas. Before Turbo discs existed, hand polishing of flat granite was done with Ceramica – a flexible diamond disc. Although performance was acceptable, most often a wavy finish was obtained due to the flexibility of the Ceramica discs.
ALPHA FELT WHEELS The Alpha Felt Wheel is a very popular material for the final buff process in stone fabrication. Alpha Felt Wheels are Velcro™ backed buffing wheels designed for use with polishing powders, polishing pastes, and polishing bars to bring out a deep glossy finish on marble and delicate granite edges such as ogees & bullnoses. Marble fabricators love the luster they obtain. Monumentalists like the durability of the Alpha Felt Wheel.
Preparation before starting a job Before using the machine, be sure to complete the following preparations. 1. Installing a ground fault circuit interrupter. (GFCI) To prevent electrical shocks, be sure to install a ground fault circuit interrupt or between the main power supply and the cord of the machine. 2. Complete grounding The machine should be thoroughly grounded by attaching the grounding clip on the power cord to a known ground.
4. Make sure that the switch is off. If you plug in the power cord without realizing that the switch is on, the machine will start, and may cause an accident. When the switch lever (see “Part names”) is tilted toward the ON label, the machine is turned on. When it is tilted toward the OFF label, the machine is turned off. Make sure the switch lever is tilted toward the OFF label before plugging in the cord. 5.
1. When using the machine 1. WATER SUPPLY HOSE This hose may be connected to any faucet or garden hose. It is composed of a special kinkproof material. Replacements are available should the hose become damaged however. Water Supply Hose Garden Hose Screw on/off 2. WATER CONTROL VALVE This valve lets you adjust the flow of water through the spindle. It may be used to shup off the water entirely when changing discs.
3. POWER SWITCH On/Off Switch 2. How to grind Make sure the water is flowing. Move the chamfer machine along the stone workpiece to grind it. Adjust the water flow, traveling speed and pressure while grinding. Switch operation When the switch lever (see “Part names”) is tilted toward the ON label, the machine is turned on. When it is tilted toward the OFF label, the machine is turned off. How to handle wheels After switching the machine ON, and the motor has reached its constant rpm’s, begin grinding.
Maintenance and inspection WARNING Be sure to unplug the cord from the outlet. Otherwise, the machine may start abruptly and it may cause an accident. Unplug the power cord from the outlet. Rubber gloves and waterproof safety boots Always be sure to wear rubber gloves and waterproof safety boots. If they are worn, cracked or have any holes in them, replace them.
