6 Common Cutting Tools in the Machine Industry & Their Applications

A cutting tool in metalworking is used for ‘machining’ - a type of manufacturing process where excess material is gradually sheared off in the form of a chip from a preformed blank. Cutting may be accomplished by single-point or multipoint tools. Single-point tools are used in turning, shaping, and similar operations, and remove material by means of one cutting edge while multipoint tools are used for milling and drilling or grinding.

Requirements for a Cutting Material

In order to perform an effective cutting operation, the cutting tool must be made of a material harder than the work material itself. The tool must also be able to endure the heat generated during machining. Often times, a cutter is wedge-shaped having a sharp edge, for smoothly and efficiently removing material applying minimum strength.

The tool must be designed according to a specific geometry, with clearance angles designed so that the cutting edge can contact the workpiece without the rest of the tool dragging on the workpiece surface, for effective cutting and smooth surface finish. According to the tool geometry, the cutting tools can be classified into solid cutting tools and carbide tipped tools. MK Industrial Suppliers, a leader in the industrial tool supply business for over 3 decades, presents you a list of cutting tools that are most commonly employed in the metal industry.

Types of Cutting Tools According to Their Applications

  1. Reamer

A reamer is a type of rotary cutting tool used in metalworking. ‘Reaming’ means to enlarge a hole. It is used to add finishing to the hole opened by a drill according to the required accuracy. Precision reamers are designed to enlarge the size of a previously formed hole by a small amount but with a high degree of accuracy to leave smooth sides. Non-precision reamers are used for basic enlargement of holes or for removing burrs. A burr is a raised edge or small piece of material which has remained attached to the workpiece after modification.

  1. Drill

A drilling machine is primarily used for cutting round holes into wall, metal, wood, etc or even for driving fasteners. This task is accomplished using a ‘drill bit’ which comes in various diameters and material composition to drill holes accordingly. MK industrial suppliers provide a range of Guhring drills which are best in class.

  1. Milling cutters

Milling is a cutting process where a cutter is used to remove the material from the surface of a metal or workpiece. It has multiple cutting edges on the outer surface or the end face of a disk or cylindrical body to cut the workpiece while rotating. Milling cutters are typically used in milling machines or machining centers to perform milling operations. Kyocera cutting tools is a notable manufacturer of a wide range of milling tools for a number of varied industries like construction, aerospace, machinery and automotive.

  1. Broach

A broach is a toothed tool used for machining the surface of a workpiece. This process is called broaching. Commonly machined surfaces include circular and non-circular holes, splines, keyways, and flat surfaces. Broaching is used when precision machining is required, especially for odd shapes. Broaches can be categorized based on their usage, purpose, direction of motion, construction & function.

  1. Tap & Dies

Taps and dies are tools used to carve a threading path on the screws. A tap is used to form the nut while a die is used to form a bolt. When a tap is used to cut or form threads, the process is called tapping, and when a die is used for the same, it is called threading. The cleaning up of thread is called chasing, for which both can be used.

  1. Chip Breaker

The purpose of a chip breaker is to improve chip control and reduce cutting resistance. The chips formed during the metal cutting are sharp and hot. This spells danger for the machine operator. The chip breaker deflects the continuous chip to a sharp angle so that they break into small manageable pieces. These small chips can then be removed by fluid or can be allowed to fall into the chip pan of the machine.

Fenner Drives B-LOC Compression Hubs

Fenner Drives B-LOC Compression Hubs – Specifications & Working

The compressions Hubs from Fenner Drives, known as B-LOC, are external locking devices that provide a unique method for mounting components without the need for a hub. This is accomplished by utilizing axial compression to hold the mounted component in place, while simultaneously using radial pressure to generate an interference fit with the shaft. This is ideal for mounting narrow components to a shaft like flat chain sprockets or mounting components that cannot be subjected to tensile (hoop) stresses. Here’s a detailed technical analysis of the B-LOC compression hubs by MK Industrial suppliers. MK industrial suppliers is a leading Industrial tool supply company and a MASTER DISTRIBUTOR For ‘Fenner Drives’ products such as Fenner Drives Link V-Belts (Power Twist, Nut Link, Super T Link, Power Twist Wedge Link V-Belt), Eagle PU Belts, B-Loc and Trantorque Keyless Locking Device among other industrial brands in India.

Operating fundamentals of B-LOC devices
B-LOC Compression Hubs differ from other keyless locking devices in how they engage the mounted component. The outer tapered rings are drawn together to generate an axial clamping force, instead of creating a radial force on the mounted component. In this way, the mounted component is not subjected to tensile stresses. This operating principle also allows narrow components to be mounted with a much better run out.

Recommended surface finish
Ideally, the shafts which are to be used with B-LOC compression hubs are recommended to have a surface finish anywhere between 32 & 125 micro inches. On the other hand, what’s not recommended is a smoother surface finish such as that found on components which are turned, ground and polished, as the union could result in a failure of connection. Note that using the combination of longitudinal abrasion and a filing sheet such as a bastard file or emery paper, the surface can be roughened for finishes below 32 micro inches / 0.8 micrometers. The recommended surface finish on the contact faces of the mounted component is between 32 and 250 micro inches (0.8 – 6.4 micrometer).

Concentricity
Concentricity is a complex tolerance used to establish a tolerance zone for the median points of a cylindrical or spherical part feature.The keyless locking devices by Fenner Drives are precision machined in order to increase concentricity and decrease runout. Several variables, including the components themselves, affect the final installed concentricity of mounted components. In the case of B-LOC Compression hubs, machining the bore and contacting faces of the mounted component to tight tolerances can help minimize the total runout.

Taking care of the B-LOC devices using adhesives & lubricants
B-LOC Keyless Locking devices are supplied with anaster oil specific to the product line. Oil is required to provide the necessary coefficient of friction to the sliding surfaces. Anaerobic adhesives such as Loctite, Permatex or similar compounds are not to be used with Fenner Drives Keyless Locking Devices as it could result in unknown contact pressures and capacities. CRC3-36 is the approved lubricant to use with B-LOC Compression Hubs.

What is B-LOC made of?
B-LOC Keyless locking devices are manufactured using carbon steels and heat treated alloy steels. In case the operational environment is corrosive, the corrosion resistance can be improved by sealing with grease or silicone, or by the use of protective cover plates and application of industry standard plating materials such as nickel, thin dense chrome, etc.

PowerTwist Drive – A Design to Outperform the Existing Link Belts

PowerTwist Drive – A Design to Outperform the Existing Link Belts

PowerTwist Drive, a new power transmission Link V-Belt from Fenner Drives, does not require re-tensioning after installation. This means there is no need to go back and take links out after installation. The V-Belt which comes in bright red & blue color, is the recommended link V-Belt for all power transmissions. The new product saves time, labor and money. Because tension is optimized with PowerTwist Drive, the equipment it serves runs better and more efficiently.

What’s new with the PowerTwist Drive

The Fenner Power Twist Link V-Belt is a significant development over both, rubber V-belts and the traditional link belting products which faced tension decay. They are now made of high-performance polyurethane/polyester composite material which is resistant to heat, cold, oil, grease, water and many common industrial and agricultural chemicals. The new polyurethane belts maintain optimal tension throughout the life of the belt. Polyurethane has higher abrasion, cut, and tear resistance. It can be manufactured with a higher hardness rating having better load bearing capacity. As an additional commercial upper hand, polyurethane can be easily colored and is resistant to many of the chemicals. It is also easier to mold into shapes and sizes in a cost effective manner. It reduces vibration in the drive system by 50 percent, limiting system noise and extending bearing life.

Reduced Cost, Longer Duration

Various tests conducted to track the tension decay of PowerTwist Drive against an earlier version of the product revealed that PowerTwist Drive maintained the required tension throughout the test in comparison to the previous product which required removal of links after a certain ‘run-in’ period. This helps heavily with the cost savings. POWERTWIST power ratings are comparable to standard RVBs.

Setup of PowerTwist Drive

The installation process of PowerTwist drive is similar to the PowerTwist link belting with the exception of the length of belt which may somewhat vary. Like all PowerTwist products, PowerTwist Drive drops right in to existing pulley setups. The speed recommendations are dependent on the pulley diameter. The linear speed capability of the V-Belt is 5,000 ft/min. When installed and tensioned correctly, it will not wear out standard steel or cast iron pulleys any faster than a RVB.

Guide to Identifying the Right Drill Bit for Your Job

A drilling machine and drill bits are one of the most fundamental hardware you can have in your home toolbox considering its applicability in just about any project. Be it a quick fix to your furniture, hanging an LED TV on your wall, or even a major room upgrade, those guhring drills in your house will get it done for you. But finding the right drill bit for your purpose can be quite a daunting task. Drill bits are available in a variety of shapes, sizes, and coating materials. It helps a great deal when you know your options. Here’s a quick overview of several types of drill bit materials and their design types brought to you by MK Industrial Suppliers - leaders in industrial tool supply & dealers in guhring tools.

Common Types of Drill Bit Materials

Carbon Steel

Carbon steel bits are a bit inexpensive, but are not so firm on the hold and require frequent sharpening. They are mainly used only for drilling wood or a few soft metals. If they are overheated due to frictional heating while drilling, they may lose their temper, resulting in a soft cutting edge.

High-speed steel

HSS bits are hard and much more resistant to heat as compared to high-carbon steel. They can be used to drill metal, hardwood, and most other materials at greater cutting speeds than carbon-steel bits.

Cobalt (HSCO)

Cobalt is considered an upgrade from HSS because it includes 5-8% Cobalt blended into the base material. This is a great option for drilling into harder steel as well as stainless steel. However, they are a bit more brittle than HSS.

Carbide (Carb)

Carbide is the hardest but most brittle of the drill bit materials. It’s used mostly for production drilling where a high-quality tool holder and equipment is used. It should not be used in hand drills or even drill presses. These drill bits are designed for the most demanding and hardest materials.

Types of Drill Bit Coatings

•  Black Oxide is an inexpensive black coating which helps reduce friction and increase chip flow. It also provides heat resistance and lubricity along with protection against corrosion. It is not suitable for nonferrous materials.

•  Titanium Nitride or TiN (gold color) is a very hard material used to coat a high-speed drill bit. It extends the drill life by at least 3 times. Even after sharpening, the coating provides an increased tool life.

•  Titanium Aluminum Nitride or TiALN (violet color) is similar to TiN except that it increases life by 5 times or more. It is used in high-alloy carbon steels, nickel-based materials, and titanium and not used for aluminum.

•  Titanium Carbon Nitride or TiCN (blue-gray color) is a coating superior to TiN. It is great for stainless steel, cast iron, and aluminum. It is harder and more wear-resistant than other coatings.

Design Features

•  Common drill point angles

The most common angles for drills are 118° and 135°. These angles are existent from the time when drilling was largely a manual process, and the drill bits were conventional conical shapes. The drill points found on most jobber drills are 118°. They are typically used for cutting into soft metals such as aluminum. The 135° variant, which is flatter than 118°, is best suited for hardened materials, such as stainless steel.

  Flute Design

  1. Standard – This type is the most common with 30° angles
  2. Parabolic Design - The open structure of this design helps in the removal of the chip out of the hole. These are most effective in extra soft materials like plastics and aluminum.
Metal Cutting Tools

Everything You Need to Know About Metal Cutting Tools

It cannot be emphasized enough how cutting tools form an integral part of the machining industry. They have been around since ages and have just become more sophisticated with time. Almost every process associated with the mechanical industry such as drilling, cutting, profiling, welding, bending and milling requires some or the other sort of precision metal cutting tools. All of these tools are required to be high-grade so as to increase the productivity.

Being a part of the machining business, you must be well versed with the significance of precision tools. Moreover, as a business owner, the importance of high-grade industrial tool supply need not be stressed. But there are many out there who have minimum to no idea about the common tools and their brands. This article is all about metal cutting tools and the desired features to look for.

What is a Metal Cutting Tool?

You must have heard of Guhring drills, Guhring tools, Kyocera cutting tools, etc. These are metal cutting tools or drilling tools that serve the primary purpose of removing leftover material from a manufactured piece of metal by employing the process of shear deformation.

There are two main types of tools that are normally utilized for cutting and they are as follows:
• Single point tools
• Multi-point tools

Single point tools are majorly used to get rid of the extra material through cutting the edges during processes like shaping, plaining, turning and other related procedures. On the other hand, multipoint tools form a crucial part of processes like grinding, drilling and milling.

Features to Look Out While Buying a Tool:

• Persistence:

The first and most important quality of a tool should be persistence or resilience. It is very important to make sure that the cutting tool is harder than the material which is ultimately going to undergo the cutting process. Toughness is essential as without it the tool will not be able to withstand the heat which is produced whilst the cutting process.

• Precisely made:

The tool needs to be precisely made with the right geometry and clearance angles. This will facilitate smooth usage of the tool and also make the entire procedure efficient and beneficial.

• Should have a long shelf-life:

Normally these tools are pretty expensive and you cannot keep on investing in them again and again, hence, you need to find a reliable supplier who can provide you with tools that promise you a long and fruitful tool-life.
