We were on the sets of AAJTAK TV Channel for a programme. We never knew that the guest present will be the famous cricketer Harbhajan Singh Bhajji. He came to the stage amidst claps from the audience. We asked so many questions from him and that too LIVE on the channel. After the programme we got the opportunity to get pics clicked with him. Really enjoyed the show. It was a great moment for all of us. 

The trend is back again : Sand blasting of Denim Jeans

A few years ago there was a great trend of Sand blasting of Denim jeans using a portable machine with compressor. The abrasive media being used was the steel shots. Than all of a sudden, the trend vanished for few years. Surprisingly, the market has again started doing sand blasting of Denim jeans. But caution must be taken while using a machine and while using the abrasive media.

Selfie with Kapil Sharma !

I am a big fan of Bittu Sharma Alias Kapil Sharma of the Comedy Nights show. It was a chance meeting with him at the Kempinski hotel in Delhi where he had come to promote his new film. While asking a question in the PC, i just asked him for a SELFIE for which he replied laughingly that i am very selfish. But after the show, he himself called me on the stage and clicked a selfie with me. It was indeed a great moment for me i.e. being on stage with Kapil Sharma.

Surface Finishing Machines !

Metal components must be Deburred, Cleaned & Finished, before affixing them into any of the bigger mechanism. These metal components may be the sand castings, forgings, aluminium die castings, zinc die castings, brass & gun metal parts, sheet metal or tempered components.

In the earlier days, people used the Tumbling barrels, loaded with leather particles ( even now being used at many places ) for cleaning & finishing of metal parts. Later the Vibratory finishing machines, Centrifugal finishing machines, Drag finishing machines as well the Roll Flow finishing machines came into operation. Various types of ceramic stones, plastic stones, stainless steel media, walnut shells, glass beads are used in this type of machines for deburring & polishing of metal components.

Similarly, Rotary barrel shot blasting machines came into existence in the earlier days for abrasive blasting on metal parts for cleaning & finishing. Later the horizontal model of Shot Blasting machines came into action such as Tumblast shot blasting, Table shot blasting, Hanger shot blasting & the continuous conveyor shot blasting machines. These machines have a centrifugal blasting rotor that rotates mechanically, whie throwing steel balls, normally called shots or grits, on the components for the finishing.

Sand blasting machines are also available in portable models as well the cabinet models. The cabinet model of sand blasting machines include various models such as pressure blasting, suction blasting as well the wet blasting machines. These machines can be used to clean & finish any specific area of a metal component also. Sand blasting nozzles of boron carbide & tungsten carbide are used in these machines & these are operated by the air pressure provided by a compressor. Sand blasting as well glass etching is also being done now a days on glass, by using these sand blasting machines. Various types of abrasive medias such as aluminium oxide, glass beads, river sand, shots, grits, plastic abrasive, garnet etc can be used in these machines.

The latest in surface finishing machines include the Thermal deburring machines, Electro chemical deburring machines, Dry ice blast cleaning machines, Micro sand blasting machines & a lot more. More details can be viewed in the Directory of Finishing machines which offers a wide range of machines as above.

Shot Blasting Machine - Tumblast Model

In Tumblast, a conveyor belt rotates inwards, inside the chamber of the shot blasting machine & the components are loaded on it as per the size & capacity of the machine. The door is than closed. Rotor is switched on for throwing Shots or Grits on the components. By this process, the loaded components get a universal finish. Abrasive medias such as Shots or Grits are continuously fed by the elevator of abrasive media. All the dust extracted in the process goes to the attached dust collector. On completion of desired time period, the door is opened & than the conveyor belt is driven outwards. As a result the components can be removed from the chamber. An automatic loading system can also be attached to the shot / grit blasting machine.

The Tumblast shot / grit blasting machines are available in many sizes, right from a 2 cu ft capacity machine to a 15 & 20 cu ft capacity machines. Some of the sizes are: 20" x 27", 20" x 42", 27" x 36", 30" x 43", 36" x 42", 42" x 42" as well 48" x 48". Tumblast 20"x27" machine has two options of Dust collector i.e. 16 Bags & 48 Bags. The work with heavier sand particles such as sand castings require a 48 Bags dust collector whereas Aluminium die castings or components with very little sand particles may use a 16 bags dust collector.

Similarly, Hanger model Shot blasting machines are available in Single / Double door type, Centralised hanger type as well a monorail type. In this model, the components are hanged instead of loading on the conveyor belt. Rest of the process is same. The hanger rotates for a universal finish using multiple rotors depending upon requirement. The benefit is that the components do not touch each other in the process of finishing and hence are scratch free.

Swing table model shot blasting machines are suitable for bigger or heavier components or if the smaller parts are to be shot blasted only one side. Many sizes are available from a minimum 36" of table to 120" of table in sngle as well double doors.

Continuous conveyor model shot blasting machines are suitable for smaller components which are to be shot blasted only one side with a single rotor. Multiple sides can be finished by using multiple rotors. Components are fed from one side & removed from the other side duly finished.

The spare parts mostly wearable are made from ni hard or alloy steel to get the maximum life.The main spare parts include the Rotor, Blades, Spring locks, Cage & Impeller, Cage adapter, centre plate, Top segment, Side liners, Round plates as well the conveyor belt. Few precautions are necessary while running the machine.

The Tumblast model of Shot blasting machine if to be used for finishing of smaller components is best suitable and very cost effective. we can be contacted with details of your components for a suitable size & model of shot blasting machine.

#TalvarThisFriday by Meghna Gulzar

If you want to know and understand that how the law enforcing agencies operate in our country & how we are at the mercy of those who have the responsibility to deliver the justice to the society, you must watch the new release, i.e. TALVAR by Meghna Gulzar on 2nd October itself.

I am sure all of you must have heard or read the entire news story of Aarushi Talwar, who was murdered at the age of just 14 years. Someone had slit her throat. The family servant was also found dead, again with the same modus operandi, i.e. throat slit. 

The news had shocked everyone with a big question that how the parents could kill their 14 years old daughter. But the investigation agencies had termed the murder as the Honor Killing stating that the parents of Aarushi Talwar i.e. Dr Rajesh Talwar and Nupur Talwar had seen her in the compromising position with the servant.

Directed by Meghna Gulzar - daughter of Rakhee & Gulzar, the movie has given three perspectives to the murder with an absolutely unbiased approach to the case and lets the audience decide which version of truth they want to believe. The question remains that why we can’t have a system that can deliver justice without any favour, without any pressure, without any discrimination and without any delay as the justice delayed is justice denied.

Vishal Bhardwaj has rightly pointed the name TALVAR towards Aarushi as well as for Goddess of Justice who is blindfolded, carries a weighing scale and a sword to give the justice by way of treating everyone equal in front of the law.

While viewing the special screening of the movie we were just speechless. It clearly showed the role of investigating agencies that can turn the investigation in any direction they prefer.

Irrfan Khan plays the role of an investigating officer, while Neeraj Kabi and Konkona portray the roles of Aarushi's parents with Tabu in a special appearance. As usual Irrfan has given a great performance and his dialogues are very catchy. Konkona looks beautiful and has done complete justice to her "unusual" character of a mother convicted of murdering her own child. A must watch movie, being released on the 2nd October. Don’t miss it if you really want to know that what happened to Aarushi.
