• What Is Valgro-Fynex ?

  “Valgro-Fynex” Non-woven Surface Conditioning Products consist of a 3 dimensional synthetic nylon fiber web, impregnated throughout with abrasive particles, bond with resin for longer life cycle.

• Why Use “Valgro-Fynex” Non-Woven Surface conditioning Abrasives ?

  For batter and consistent improve surface finishing without changing of dimension, and are ideal for all cleaning, Deburring, finishing polishing, and blending operations where extremely controlled and minimal stock removal is required, that is without damaging the base material.

• Which tools are suitable for Valgro products ?

  Bench motors, Hand tools, Lathes, Grinders etc.

• When would a Cross Buff be used ?

  A Cross Buff is ideal to use when cleaning or polishing the ID of tubing and other small areas.

• When would a Flap Brush be recommended over ganged Buff & Blend Discs ?

  When working on a part with a consistent profile, a Flap Brush will hold its shape and last much longer than ganged discs.

• When profiling a Non-Woven wheel for deburring, what product will hold a dress better, Convolute or Unitized ?

  Because of its construction a Unitized Wheel will hold a dress much better than a Convolute.

• Why I used convolute wheels against HP / Unified wheels?

  Because of its life is 50 times batter, and less wear tear during use. Less pressure is require, faster finishing action.

• What is the difference between a Flap Brush and a Combi-Wheel ?

  A Flap Brush is a wheel made exclusively from non-woven heavy duty Valgro-Fynex material (flaps) and is used for finishing applications. As the name denotes, a Combi-Wheel is a combination of alternating flaps of Valgro-Fynex and Coated Abrasive material creating a "firmer" wheel that provides a higher rate of cut.

• What is the difference between a ZMB, MED and a CNP Convolute Wheel ?

  The ZMBis considered a Light Deburring and polishing Wheel for removal of small burrs and when a fine polish finish is required.

  The MED consider when medium and small burr removal with finishing of metal parts, Mainly use for gridline conditioning.

  and CNP Cut N polish wheels is micro stock removal is a harder wheel designed for more rude deburring applications.

• What is the difference between a Coarse Buff & Blend Disc and a Medium fine Buff & Blend Disc ?

  The Coarse Disc will be more durable and blend faster. faster cutting rate and provide deep grains finish, Medium and fine discs for general cleaning and finishing operation.

• What is the best product to use for removing surface contaminates and rust without effecting the base material ?

  Initially a coarse or medium combi Flap wheels. For heavier contaminates, like adhesives in paint, start with Strip-cut, as Strip-cut is non-loading with a fast cut rate. For light cleaning use plain coarser grade flap brush

• What are the two more common stainless steel finishes ?

  Standard mechanical sheet finishes are commonly un-finished or finished prior to fabrication. The un-finished 2B finish is a bright cold-rolled appearance with no grain. The 2B is usually a preliminary step to a grain finish. The finished No. 4 is the most common general purpose bright finish. This is achieved with many VAlgro Abrasives products, including, Metal Finishing Convolute Wheels, Flap Brushes, Combi-Wheels, and Flap Wheels.

• What are the 5 most recognized characteristics of the Metal Finishing Convolute Wheel ?

  Finish, Finishing Rate (how fast the desired finish is achieved), Flexibility, Durability, and Life.

• Using a Metal Finishing 8AM Convolute Wheel, how can the final finish be manipulated without changing specifications ?

  Change in wheel speed, feed speed, feed pressure, and dwell time will effect the final finish. Higher wheel speed with light pressure will produce a finer finish, while lower wheel speed and heavier pressure will produce a coarser finish.

• What are some methods that can be used for truing a non-woven wheel ?

  24 or 36 grit coated abrasive material or a custom metal tool.

  • Coated abrasive material : A piece of coarse (24 or 36 grit) coated abrasive material and a heavy solid piece of metal is used. By wrapping the coated abrasive around the metal and applying pressure to the wheel as it spins, the wheel can be trued.
  • Custom metal tool : The tools are usually thin, short, have a sharp edge and right angle to reduce the chances of snagging the tool with the wheel. This method is best utilized on softer density Convolute / Unitized Wheels, Flap Brushes and ganged Buff & Blend arbor hole discs.
• Which products, manufactured by Valgro Abrasives, produce a #4 finish (bright finish with visible grain which prevents mirror reflectivity) ?

  Flap Brushes (mandrel mounted and arbor hole), Combi-Wheels, Metal Finishing Wheels, and/or Rapid Cut Surface Conditioning Belts.

• Does Valgro Abrasives manufacture a non-woven product that can produce a mirror finish ?

  Valgro Abrasives produce a buffing paste that will achived a mirror finish.

• How does an increase in contact pressure effect the cut rate of a Convolute wheel ?

  An increase in the contact pressure allows the wheel to break down, continually exposing fresh layers of grain, resulting in a higher cut rate.

• How does the density of a Convolute / Unitized wheel effect the cut rate ?

  The harder the density of the wheel the smaller the contact area to the workpiece. This will result in higher stock removal. The softer density will result in a larger contact area, thus, reducing the cut rate to the workpiece.

• Why Flap wheels is broken during operation ?
  • Fitting is not proper on tool.
  • Coated Flap has been used in reverse direction.
  • Excess work pressure on job. It make Hammering effect on higher RPM.
• When should a Buff & Blend Disc be used in lieu of a Surface Conditioning Disc ?

  Buff & Blend discs are primarily used for blending and polishing. If sharp edges or heavy burrs are to be removed, Surface Conditioning is a better recommendation. Surface Conditioning requires heavier pressure to maintain a consistent rate of cut.

• What is the advantage of using a Resin Fiber Disc compared to a Flap Disc ?

  A Resin Fiber Disc will have a higher cut rate and a lower acquisition cost. A Flap Disc will provide longer life and reduced disc changes, which can result in overall cost savings.

• What coated products are best for I.D. work ?

  Flap Wheels, Kay Rolls, Cartridge Rolls, Tapered Cone Points, Slotted and Overlap Cloth Discs, and Cross Pads.

• How can I get the quickest stock removal while using a Quick Change Disc ?

  By increasing the angle of the tool, so that only the edge of the disc is attacking the workpiece.

• What is the difference between aluminum oxide and silicon carbide ?

  Silicon carbide creates a thinner scratch pattern due to being a sharper grain than aluminum oxide. Silicon carbide cuts faster but does not last as long as A/O.

• Where should I use a flexible flap wheel vs. a standard flap wheel ?

  The flexible flap wheel dusts less than the standard wheel in deburring applications. When a mandrel mounted wheel is used for I.D. work, the flexible wheel will collapse to better polish the walls of the I.D. without stalling the tool.
