Blanchard grinding, also known as rotary surface grinding, is one of the most accurate, efficient and cost effective methods for finishing flat surfaces on various heavy metal materials.
Variable Speed Drive
Variable speed drive (VSD) technology uses the motor current to control its speed, reducing the energy required to operate. This can be especially useful for power systems that are prone to running at part load, such as fans and pumps.
However, these technologies aren't suitable for constant torque loads like machine tools. They are able to offer energy savings only when the operating speed of the motor is reduced, but this is not always possible.
Fortunately, there are other ways to control the speed of an electric motor that doesn't require the use of a VSD. A static drive, for example, can be used to achieve this, but these are often prohibitively expensive. Another option is a variable speed fluid coupling, which can also save energy and provide very accurate and precise speed control. The choice between these two methods is up to the application engineer, who should judge which one is most appropriate for a given system.
Spindle Speed
A spindle speed calculator can be helpful for determining the correct spindle speeds for various lathe and milling operations. This can help you select the appropriate rpm for each application, while minimizing cycle time.
The machinable material, the type of the cutting sequences being used and the machine tool’s spindle drive system are all factors that can impact a program’s selection of rpm. This may be especially true if a machine tool has several rpm ranges that overlap.
This can result in unnecessary changes to the machining programs when changing tools. It can also put unnecessary strain on the machining equipment’s drive system.
A surface grinder can remove stock from a workpiece in an extremely short amount of time with extreme accuracy. Using a Single Surface Grinding Machine can help you meet dimensional specifications and eliminate the need for machining centers or other high-end machines.
Feed Rate
When machining High Precision Surface Grinder or Precison Double sided grinder machine parts , one of the most important factors is feed. It is critical for producing the right size and finish with a low Ra value.
There are many methods of achieving the correct finish, but there are only a few that are most effective. Some of these include in-feed, form, plunge, and profile grinding.
Depending on the type of part being ground, each method may have its own advantages. For example, in-feed grinding can make cubic parts of metal square and parallel, which is useful for a variety of applications, including fixtures, molds, and dies.
In-feed grinding can also be used to produce taper in workpieces, similar to plunge and form grinding. It requires no holding of the workpiece and reduces the wear of the machine.
Coolant
Coolant is a critical part of the grinding process. It helps keep the wheel cool, cleans the grinding zone and lubricates the wheel to reduce wheel wear.
A high-quality coolant system delivers the correct concentration of a diluted mixture of synthetic or soluble oil. Coolant systems also contain additives to help maintain a safe and productive grinding environment.
Synthetic and semi-synthetic fluids have more lubricity than soluble oils but are often prone to fire hazards due to anaerobic sulfate-reducing bacteria that produce toxic gases.
Soluble oil based coolants have higher lubricity than synthetics but have poor cooling and cleaning properties. Straight oil dispersed in air is more flammable than soluble oil and has less lubricity than synthetics.
Vacuum attachment of interchangeable flexible abrasive island discs protects the precision flat platen surface from abrading action. Non-flat areas on the surface of the island discs are easily removed to reestablish precision flatness during an abrading operation.
