Linear Vibratory Continuous Finishing System (German Design) Polishing Machine Buffing Machine

Continuous Flow-Through Longitudinal Vibratory Finishing Machines

If you operate on an industrial scale and in search of finishing machines that can process maximum number of parts in a minimum time, you need a continuous flow-through longitudinal vibratory finishing machine. These machines can cycle products in as less as 10 minutes thanks to their high-speed converter and tilt angle.


Product Description

The continuous flow-through longitudinal vibratory finishing machines allow in-line production along with continuous parts flow. If you want the most out of these machines, you can connect multiple casting machines with them in the early stages of production.

The unique selling point of this machine is that it only needs one operator. You can save a lot of money on labor costs. The operator alone can load all the parts into the conveyor belt and assemble them once they are done.

Linear Vibratory Finishing System Introduction

With the recent increase of cost in the manual polishing process and high requirement of automation, the continuous linear vibratory finishing machine is gaining preference for industries for large production volume especially medium to large-sized work parts.

The machine and process developed by Inovatec offer a good choice for finishing the solution of high-quality standards. The result is repeatable and the process is customized according to customer requirements. So far, the continuous linear vibratory finishing system is one of the most popular types of mass finishing machinery around the world.



Linear Vibratory Finishing Machine Structure Details

The superior equipment concept of the Inovatec linear continuous vibratory finishing systems is based on the fact that all processing is made in control. The complete processing is designed based on specific requirements. The vibratory motor, a separate unit with customized design as well as PLC control station make sure the long-lasting life of the machine and repeatability of the process.


Processing chamber

  • The enhanced welding structure is designed to sustain a heavy load
  • Post-heat treatment and shot blasting after welding to release stress
  • Heavy-duty USA DuPont PU material
  • Optional water dosing over the complete length of the processing chamber
  • Recycling water/continuous dosing available

Special discharge section

  • The design of the discharge section at the exit of the processing bowl is based on fluid mechanics and can be adapted to different finishing tasks as well as workpiece shapes, sizes, and weights.
  • The discharge section is equipped with a patented media to unload the gate.

Change of media

  • In case of a required media change, the discharged media is returned to a media bin with a special belt conveyor (optional).

Vibratory drive system

  • Powerful Inovatec vibratory drive
  • Adjustable imbalance weight units equally distributed over the entire length of the processing bowl electronically controlled supply of the imbalance units with grease (automatic greasing)

The inclination of the processing bowl

  • The processing bowl is placed on four air cushions made from rubber, thus insulating the surrounding area from induced vibrations
  • Process time can be adjusted between 4 and 30 minutes by inclining the processing bowl using air cushions
  • Reduced noise emissions

Base frame

  • Torsion-resistant, stress relieved and sturdy welding construction
  • Base fame placed on vibration absorbing special supports

Working Principle of Linear Vibratory Finishing Machine

The parts are continuously fed into a linear processing chamber with a certain cycle time, together with ceramic media or plastic surface finishing media. The sidewalls of the processing chamber can either be U-shaped or straight according to customer requirements. The vibratory force generated by a high-frequency motor rotates the mass along the chamber wall. Meanwhile, work parts are moving forward together with mass media.

The processing parameter includes processing chamber angle setting, balance weight for motor, motor frequency as well as time control.

After the work parts went through the whole processing chamber, media and parts can be separated in a nylon sieve unit. In the meantime, parts can be cleaned and with spray water and possible post-treatment, for instance, vibratory drying machine or chain belt drying machine.

After all, the media after being separated from parts are returned to the processing chamber for recycling.

Linear Vibratory Finishing Machine Applications

The linear continuous finishing machine is suitable for casting components from medium to large size, especially for components with continuous production and delicate high-valued products. For example, alumina alloy die casting parts, magnesium alloy die casting parts, steel engine housing as well as other structural components. The processing includes deburring, surface grinding, edge rounding, polishing as well as ball burnishing.

Productivity is high compared with manual processes and easy to achieve automation.
