Introduction

Vibratory Finishing Machines are mass finishing machines, used for deburring, polishing, descaling, and surface improvement on metal and plastic components.

Working Principle

The machine has a steel bowl lined with rubber or polyurethane which is filled up with required media (either ceramic, plastic, maize etc. depending upon the finish required) and components. Eccentric weights are mounted on an extended shaft attached to a heavy duty motor to cause vibrations and create a spiral of the media and the components. Variations in vibration, achieved by varying weights and angles, and suitable combination of media enable machine to be used for different components.

Introduction

Centrifugal Finishing Machines are high ‘G’ force machines specifically developed for smaller components, and for those that require long process times in Vibratory Finishing machines. Smaller machines have removable barrels, while larger ones have fixed barrels with provision for barrel and turret inching. There are several options available -- straight barrels, inclined barrels, removable barrels (for small machines), variable speeds, media parts separators, inching arrangements, rubber/polyurethane linings, conveyors, etc.

Dalal In Association with Vibrochimica

Dalal Engineering has entered into an agreement with Italian specialists Vibrochimica, for manufacture of Centrifugal Disc Finishing and Rapid Ball Burnishing machines. Vibrochimica, founded in 1972, is one of the foremost European manufacturers of Vibratory Finishing Machines and Systems for the surface treatment and mass metal finishing markets. The company is located in Liscate, Italy near the Milan-Linate Airport. Their product range includes Round Bowl Machines, Tub Machines, Ball Burnishing Machines, Centrifugal Disc Finishing Machines, Vibratory Dryer, Through Feed Continuous Machines, Waste Water Treatment System and fully automated High Tech Installations.

Introduction

Rapid Ball Burnishing machines are the best solution for polishing of components where there is need of a high production / short process time. These machines can work in batches for polishing of small and medium sized parts.

These machines have a high frequency technology where the total process times are between 10-20 minutes.

These machines work in batch for burnishing of ferrous & non ferrous components. They have a unique tilt separator inbuilt for 100% separation of parts within 2-4 minutes and further for the auto return of media back to the burnishing tub.

Introduction

Vibratory Tub Finishing Machines have rectangular working bowl with either straight or curved side walls based on the application. The system cascades mixture of media and components in the Tub, producing relative movement between the two. This results in efficient processing of components. Vibration can be adjusted with eccentric weights and systems can be batch type,customized as per needs.

Features:

• Suitable for large and long parts
• Machine can be customized to suit parts
• Continuous Machine can be offered
• Divider plates for large heavy parts and moving parts to prevent contact

Advantages:

• Faster processing than hexagonal barrel
• Can handle small to very large and very long parts
• In-Process Inspection
• Batch or continuous operation

Introduction

Dalal Magnetic finishing machine makes use of innovative magnetic field power to move the steel media rapidly. For deburring, polishing, descaling and cleaning of nonferrous parts.

Principle

The steel media, work pieces and the polishing chemical are put together in a container which is placed on the machine. A powerful magnetic field is generated which results in moving the magnetic steel pin media over the parts to achieve the designed results.

Special Features:

• Excellent deburring and edge chamfering.
• Good for irregular shaped parts, internal holes, etc.
• No deformation, No surface damage.
• No effect on accuracy of parts.
• Long life steel media.
• Easy to use.
• Short process time 5 mins to 15 mins.
• Able to work in difficult to access areas such as recess, slots and blind holes.

Application:

• Deburring.
• Polishing
• Descaling
• Derusting.

Introduction

Dalal Vibro Dryers are designed for stain free drying and polishing of components, immediately after vibratory/centrifugal finishing.

Heated Maizorb/Corncob is used as the drying media. The rubbing action of the mass eliminates the calcareous residuals of the evaporated water deposited on the surface of the parts. The equipment is offered in, both, batch and continuous operations.

Special Features:

• Continuous and re-circulatory operation can be automated and added to total system
• Mobile, robust, fast and easy to install
• Occupies lesser space
• Adjustable vibration to suit production requirement

Advantages:

• Can handle small to medium size parts.
• In-Process Inspection possible.
• Energy Efficient.
• Excellent cascade to eliminate calcarious residuals of water.
• Stain free drying
• Occupies less space than other units of similar capacity and output

Introduction

Mass finishing is becoming increasingly sophisticated in order to provide a high level of productivity, reliability and consistency of quality as demanded by industry.

Dalal Engineering with several decades of experience in mass finishing offers customdesigned Automated systems with integration of operations like loading, washing, chemical dosing, sound dampening, finishing, separation, drying and waste water treatment. The system can be controlled by PLC with detail process monitoring and controlling all aspects of the process.

Advantages of Automation in Finishing Systems

• Increased Productivity
• Consistent Output
• Reduced Operational Cost
• Reduced Manpower
• Better Safety

Dalal Engineering offers automation with the use of latest technology to reduce the need of human work. Higher Productivity and higher output have been the major factors for the increasing demand of automation in the finishing process. Though many may claim that a human can achieve consistent finish using machines, there is definitely an increase in the consistency of finish after every batch with efficient automation.

Waste Water Filtration and Recycling System

To increase the attention towards ecology and environment, Dalal has introduced a waste water filtration and recycling system. It is an automatic and economical water treatment system with easy application and without need for specialised manpower. The system consists of one sedimentation and one clean water tank. The dirty water is passed through a high speed filtration system for removal of suspended solids and then cleaned water is collected in clean water tank.

• Less consumption of water and finishing compound
• No choke up in drainage

Sound Reduction Accessories

For workers safety and to meet factory sound norms, mass finishing equipment usually requires noise protection measures.

Sound Cover – Noise protection cover of single machine with a manually or pneumatically operated hinge type cover, covering only the top of the machine.

Sound Protection Cabin - A sound protection cabin with a complete enclosure and manually openable top and sides

Auto Loader

Bin type loader required for transfer of parts from customer bins into the machine. The loader can be customised for component bins used by customers. Efficient, Easy loading & unloading of parts without damage, Heavy Duty and Economical.

PLC Control Panel

A full automation of the system can be done with PLC Control panel where manual intervention is not required. The panel works with touch screen or line display and has HMI with feather touch buttons.

Magnetic Separator

Generally used for Separation from media of ferrous components having similar size. These can be separated magnetically. Magnetic separator can have a inbuilt demagnetiser and in some cases can be used to convey components to the next machine /dryer.

Media & Chemicals

Correct choice of media and chemicals is critical to proper surface finishing. Dalal Engineering has a partnership with Sharmic Engineering of UK for processes. This helps Dalal to develop specialized formulations to meet specific industries and metallurgies. A highly advanced R & D lab decides on the selection of media and chemicals based on the type of material and its geometry. Different types and grades of media ranging from ceramic, plastic, steel, glass to corncobs etc, each with varying abrasive strengths are available. These may be used in combination with highly developed chemical formulations which contribute to the deburring and polishing process, keep parts and media clean, prevent media impingement and assist in achieving the desired finish.

To provide a complete process solution, finishing process needs to be developed.

This all starts at our R & D Lab at Thane
