Our Spindle Technology

PushCorp offers a wide range of powerful, rugged and efficient electric spindles. All PushCorp spindles utilize liquid cooled, permanent magnet, brushless, closed-loop servomotor technology. This technology gives our spindles the highest power-to-weight ratio and power efficiency in the industry. With proper cooling, our motors are designed to run with up to a 100% duty cycle - turn them on, leave them on. They can handle high-power, continous operation for years with zero maintenance - no problem!

Servo technology allows for continuously variable speed and constant, maximum torque over the entire speed range. Finally all PushCorp spindles are designed to be easily mounted to our Compliant Tools in a variety of orientations to provide a complete end-of-arm process solution.

Industry Standard BT Toolholder

Air pressure actuated, industry standard BT-style toolholders are our most popular tool changing option. Our spindles accept either the BT30 or the larger BT40 toolholder depending on the motor size. BT style toolholders are readily available from a variety of tooling suppliers in various lengths and configurations. They provide exceptional holding torque and tool retention and can accomodate a wide range of tool diameters. This exceptional performance and flexiblity make them the go-to choice for most any application.

Manual Collet

Our Manual Collet option uses a standard ER style collet and nut. This simple, low-cost solution is ideal for grinding, brush finishing or other applications where media changes are required but not frequent enough to justify full, robotic quick change technology. ER collets are readily available from many suppliers in a variety of size options to accomodate most any tool.
