Multi-spindle wood grinding machines are a valuable part of many woodworker’s projects. They can be used for a wide variety of applications such as floor finishing, surface sanding, planer dusting, and detailed drilling into hardwoods, softwoods, or other woods. The multi-spindle wood grinding machine is also called the multi-spindle wood grinder or the multi-spindle router. The name multi-spindle wood grinding machine is based on the fact that each unit in the machine is capable of running at two speeds which gives the machine the ability to grind in two directions at once.
The spindles in multi-spindle wood grinding machines are similar to those in table saws but much shorter. They are also about one-third the length of the spindle itself. There are usually two, three, or four spindles in a multi-spindle wood grinding machine panel. Each spindle functions independently and is usually connected to the rest of the panel via a gear in the chuck. There is a spindle arm attached to the end of the panel and this spindle acts as the table in the machine.
There are many kinds of machine spindles in a multi-spindle wood grinding machine panel. Some are made of solid metal alloys or machined aluminum and some are made of soft metals such as aluminum or brass. The sizes of the spindles will determine the size of the grinding tools that can be included in the project. The different types of spindles are also designed for different types of turning operations such as crosscutting, which is the same as face cutting but it happens on a flat surface and profile is not changed, and lapping which is the opposite of crosscutting operation where the material being ground is passed through the spindle quickly and repeatedly to obtain a flat surface finish. The main advantage of using these types of spindles is that they are more suited for most applications, and they are very economical.
