VIBRATORY POLISHING MACHINE VB(A)

Vibratory Polishing Machine FAQ Guide

1. How Inovatec Machinery Controls the Quality Of Vibratory Polishing Machines?

The outer shell of the vibratory polishing machine is made up of a series of stainless steel pipes.

We make use of CAD software for designing the mechanical parts in the machine.

The laser cut machine us used for cutting machine parts with more precision and accuracy.

 

The multiple parts are joined together by welding.

The structures after welding are subjected to heat treatment and surface treatment to improve life and durability.

Thus, the machine will run for many years without developing any cracks.

It also helps to prepare the surface for painting.

We make use of a fully automatic PU casting machine for the vibratory machine.

 

The machine is kept at an optimal temperature in the curing room after casting for several hours.

It is to make sure that no pores are developing in the structure.

 

2. How Can You Select The Right Vibratory Polishing Machine?

We always recommend going with a simple vibratory polishing machine that will help you to do your polishing works,

The VBS (A) and VBS (B) models are useful to polish medium and small size parts.

VB (A) and VB (B) models are useful for significant size parts.

You can also invest in the continuous longitudinal vibratory polishing machines if you are dealing with parts that require less polishing time.

 

3. How To Select The Vibratory Polishing Machine On The Basis Of Its Capacity?

The factor that decides the vibratory polishing machine capacity is the number of parts you want to polish per day.

In order to get the actual number, you need to do some trials.

But, you need to do the calculations to find this number so that you can place the order.

The number of working hours and the part size will help you to select the required capacity for the machine.

You cannot load the machine with its full capacity.

We recommend operating the machine with a maximum load of 80 per cent capacity.

 

4. What Are The Different Spare Parts Needed For The Vibratory Polishing Machine?

We make use of branded, reliable parts for our vibratory polisher machines.

The list of parts is given below.

• The vibration motor from Wuxi Changshun or Shanghai vibration motor
