A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. A VFD is widely used, but we will focus on milling machines.

There are many benefits of using a VFD. We will mention only the most important benefits of using a VFD:

- It eliminates the need for expensive sliding variable speed pulleys.
- VFD reduces power line disturbances and alsoreduces energy consumption and energy costs
- Variable frequency drive minimizes the risk of motor damage during start and stop. Hence, it increases motor life

- User can control spindle speed electronically instead of a mechanical cranking method.

Power Drawbar
A power drawbar facilitates fast and efficient manual tool changes with the help of a push button. It eliminates the need for tightening the drawbar by hand. A pneumatic cylinder is actuated to depress the drawbar to do the job effortlessly.

It helps in releasing the clamping pressure to open the collet without applying any harmful load on spindle bearings. Apart from that, elimination of manual adjustments helps to speed up the process and increase efficiency. Our power drawbar increases productivity by reducing downtime when changing tools. They are easy to install, can be mounted on most milling machines with R8, 30, and 40 taper, and run on standard shop air supply.

We have the best quality VFDs and Power Drawbars on the market. All of our VFD’s and power drawbars are developed and manufactured in the USA after extensive R&D to ensure the highest standards of quality and reliability.
