Satellite rotary table shot blasting machine

Operation

When processing workpieces in batch mode, the rotary table is stopped, the doors are opened, and several workpieces are placed on the rotary table. The door is closed and the workpieces rotate into the blasting area and are cleaned.

In continuously operating rotary table shot blasting units, the workpieces are continuously shot blasted in the rear area of the rotary table. Loading and unloading take place at the front of the machine. Special passages seal the loading and unloading areas of the rotary table and prevent the abrasive from escaping.

Other rotary table machines operate in so-called duplex mode. While one batch is being shot, another batch is being loaded or unloaded. In duplex machines, two batches are in the machine at the same time.

In satellite rotary table shot blasting machines, the workpieces are shot blasted on radially arranged rotating platforms. These types of machines usually operate in indexing mode.

In all of these types of machines, the abrasive is continuously cleaned, recirculated and reused. An abrasive dosing device feeds the cleaned abrasive from the abrasive storage tank to the high-performance turbines.

A fan creates the partial vacuum necessary to maintain dust-free operation of the blasting unit. The extracted air is cleaned in a special filter unit.

Capabilities and applications

Conventional rotary table shot blast machines are typically loaded manually. The machines are most often used for batch cleaning of castings or die castings and for roughing part surfaces prior to coating.

In automated lines, primarily in the automotive industry, satellite rotary table shot blasting machines often include integrated robotic handling devices. This configuration is used to harden the surfaces of transmission components, for example.
