Solutions For CNC Machine Tools Using High Speed Electric Spindles

​

Our engineering team has over 30 years of experience in high speed spindle applications. We work closely with machine tool and spindle manufacturers to ensure that our drives have the best possible features which contribute to the productivity, accuracy and profitability of the machines.

​

Our quality high frequency spindle drives make a difference because spindle motor temperature (particularly rotor) is lower, which:

​

  • Prolongs bearing life and reduces machine down time and periodic spindle rebuilding costs

  • Reduces spindle shaft thermal growth and provides for better part accuracy

  • Allows maximum use of spindle motor power/torque for machining

​​

Utilizing a fast and accurate load signal along with the fastest possible touch detect function​ is used to optimize the machining process and reduce production cycle time.

spindel electronics features for id grinding

Features for ID Grinding

​

High-speed, repeatable and precise analog load or power signal is well suited for adaptive grinding. When effectively used by grinder CNC control, it can help to shorten grinding cycles. In grinding wheel dressing applications, this signal can help reduce the removal rate of expensive abrasive material.

 

Integrated fast touch sensing function (first contact, gap eliminator) with very fast solid state output can be used instead of expensive acoustic sensing in many ID grinding applications. Productivity can be improved with no additional cost.

​

Our AV Series drives were designed to be an easy functional replacement for older PAM and PWM high-frequency spindle drives on internal cylindrical (ID) grinding machines and for other high rotational speed applications. They can mimic control interface and special features of older spindle drives, whether they were made in U.S., Europe or Japan.

Fast Touch Detect and Load Thresholds Improve Cycle Time

​

Base Load update/sampling for accurate & repeatable sensing: The no load level (load baseline) is sampled either automatically or by user (CNC) controlled input and is stored before each grinding cycle.

 

This updated load level is then used as the load baseline for programmable thresholds of the Touch Detect function. Accurate and repeatable sensing is maintained even though the no load level varies from motor to motor as well as with bearing condition and temperature. 

 

Solid State Outputs switch within microseconds of the detected threshold and can also be used for effective crash protection. Reduced spindle vibration leads to better surface finish and longer spindle bearing life and part accuracy due to reduced thermal growth of spindle shaft.

 

Flexible input/output programming and complete data storage for different configurations of multiple-spindle machines (turret-type grinders).
