Attentions on Safety 1. Cautions regarding handling (1) When removing the tool from its case (packaging), be careful that the tool does not pop out or is dropped. Be particularly careful regarding contact with the tool flutes. (2) When handling tools with sharp cutting flutes, be careful not to touch the cutting flutes directly with your bare hands. 2. Cautions regarding mounting (1) Before use, check the outside appearance of the tool for scratches, cracks, etc. and that it is firmly mounted in the collet chuck, etc. (2) If abnormal chattering, etc. occurs during use, stop the machine immediately and remove the cause of the chattering. 3. Cautions during use (1) Before use, confirm the dimensions and direction of rotation of the tool and milling work material. (2) The numerical values in the standard cutting conditions table should be used as criteria when starting new work. The cutting conditions should be adjusted as appropriate when the cutting depth is large, the rigidity of the machine being used is low, or according to the conditions of the work material. (3) Cutting tools are made of a hard material. During use, they may break and fly off. In addition, cutting chips may also fly off. Since there is a danger of injury to workers, fire, or eye damage from such flying pieces, a safety cover should be attached when work is performed and safety equipment such as safety goggles should be worn to create a safe environment for work. (4) There is a risk of fire or inflammation due to sparks, heat due to breakage, and cutting chips. Do not use where there is a risk of fire or explosion. Please caution of fire while using oil base coolant, fire prevention is necessary. (5) Do not use the tool for any purpose other than that for which it is intended. 4. Cautions regarding regrinding (1) If regrinding is not performed at the proper time, there is a risk of the tool breaking. Replace the tool with one in good condition, or perform regrinding. (2) Grinding dust will be created when regrinding a tool. When regrinding, be sure to attach a safety cover over the work area and wear safety clothes such as safety goggles, etc. (3) This product contains the specified chemical substance cobalt and its inorganic compounds. When performing regrinding or similar processing, be sure to handle the processing in accordance with thelocal laws and regulations regarding prevention of hazards due to specified chemical substances.

(ANIL JINDAL) 800981002 ii ABSTRACT Drilling is probably the most frequently used operation in industry. Sometimes, as many as 55,000 holes are generally required to be drilled as in a complete single unit production of the Airbus A350 aircraft. The carbon fibre reinforced plastics (CFRP), owing to their anisotropy and abrasive nature of their carbon fibre content, exhibit totally different drilling results as compared to those of drilling common metals and other materials.

  • Gun Drilling Having Enough Coolant Flow to Gun Drill with a CNC Machine
    Technical Bulletin Gun Drilling Having enough coolant flow to gun drill with a CNC machine Gun drilling was initially developed for drilling dependable, uniform holes for rifle and gun barrels. Still used in the manufacture of armaments, the process of gun drilling, DRIVER SHANK FLUTE CARBIDE TIP also called deep hole drilling, is used in many other industries: aerospace, construction, medical, automotive, FLUTE LENGTH manufacturing, hydraulics, military, energy, oil and gas OVERALL LENGTH exploration, and plastic injection molds. Deep hole drilling refers to holes of depths at least three times their diameter. Holes can be drilled to practically any length, as limited by its machine and drill design Achieving precision and shank rigidity. Likewise, a variety of materials are Factors that influence the quality and accuracy of the used with this process from titanium, steel, and other hole drilled by a gun drill include: metals to ceramics, graphite, plastics, and wood. • pressure Advantages of gun drilling • fluid volume Compared to other drilling methods, gun drilling offers: • speeds and feeds • deep, accurate holes in a single pass • lubricity and fluid viscosity • the best method when very precise roundness and/or • drill condition straightness is required • shank sharpness • guide pads burnish the hole, often eliminating When it comes to moving chips and swarf, coolant secondary finishing volume is key. The rule of thumb is 1.5 GPM/10’ of chip • reduced cost and labor time movement in a milling operation. • gun drill tips can be reground for increased tool life Milling and CNC machines Gun drilling process The same concept holds true with gun drilling, it is the Precision is achieved in deep hole drilling with the volume not the pressure that moves the chips.

  • The Trepan Or Ring Core Method, Centre-Hole Method, Sach's Method, Blind Hole Methods, Deep Hole Technique
    THE TREPAN OR RING CORE METHOD, CENTRE-HOLE METHOD, SACH'S METHOD, BLIND HOLE METHODS, DEEP HOLE TECHNIQUE E. Procter" and E. M. BeaneyS "Procter & Ches~er(Mearuremenrs) Ltd., Theurre Street, Wawick CV34 4DP KEGB, Berkeley Nucleur Labs. Berkeley, Glor. GLl3 9PB, UK I\ ABSTRACT Mechanical methods can be used to measure practically all types of residual stresses, from near surface to depths in excess of 0.25 metre. They have been used for much longer and have thus seen more development than othel Inechocis and, ss a iur~sequence, their limitations and applications are more clearly defined. Their major disadvantage is that, by their nature, they are destructive although the amount of structural damage may be insignificant in many cases. The essence of the techniques is that changing the geometry of a structure changes its residual stress pattern. This change in stcess causes strain changes, which can be measured using strain gauges or some other deformation measuring device. In principle, if the change in geometry is known and the strain measurement is sufficiently comprehensive and accurate, then residual stresses can always be calculated. However, due to the complerity of this calculation in its general form, all the mechanical techniques rely on making well defined changes in geometry for which the relationship between measured strain and residual stress are known or can easily be obtained. The techniques fall into two categories, namely those which measure surface or near-surface stresses, and those designed to give sub-surface or through-thickness stress. The chapter considers the following techniques: Sectioning for surface and sub-surface measurement, including Sach's and Blind Hole methods.

  • Productive Deep-Hole Drilling
    Productive deep-hole By James R. Koelsch drilling Contributing Editor Drilling deep holes might not take as long as you think echnological progress in deep-hole drilling has been slow but sure, like the process itself. This observation is especially true for gun- Tdrilling, the most popular of the deep-hole drilling processes. Although modern gundrilling machines are built better than their prede- cessors, come with modern controllers, and often monitor load and other variables to protect the tool, the process has not changed since the original machine was built, according to Russell Gilman, Jr, presi- dent, Dadson Corp (Grafton, Wis). “The nuts and bolts of gundrilling are pretty much the same as they were because you can’t really make a gundrill go any faster than it’s designed to go,” he says. “Otherwise the flute packs, and the tool breaks. So specifying the right feeds and speeds for the work material is the key to success at gundrilling.” For normal carbon steel, for example, cutting speeds are usually between 300 and 350 sfm, and feed rates rarely exceed 5 ipm to manage the chips properly and avoid generating too much pressure and heat. For applications that need greater speed, Dadson recommends the single-tube systems, such as the BTA-style tools offered by American Heller (Macomb, Mich). The deep-hole specialists at Dadson tend to favor the single-tube process over gundrilling for making thousands of pieces of a particular shape because it can be three or four times as fast and needs less machinery than a gundrill.

  • 1 RIFLED BARREL MAKING of All the Components That Make up the Rifle It Is the Barrel That Seems to Hold the Greatest Mystique A
    RIFLED BARREL MAKING Of all the components that make up the rifle it is the barrel that seems to hold the greatest mystique and mystery. Anybody with basic knowledge of engineering practice could make the action. Anybody with metal working experience and machinery could make a bolt action. But the barrel, that is a different matter. How do you drill such a long straight hole to form the bore? How is the rifling put in? How is the shiny finish in the barrel achieved? And above all, what is that special something that differentiates a so-so barrel from a hummer? Each operation in the making of a rifle barrel requires a special machine tool rarely found outside a barrel shop. That said, there is no real mystery in making good rifle barrels. But it does take care and attention to detail. In this article I will outline the main processes involved in turning a bar of steel into a rifled barrel, indicating where barrel makers differ in their approach. The United States is the home of the custom barrel makers and there are literally hundreds of small barrels across the country, some still make barrels to the customer’s specifications. There are also some very large barrel makers who make barrels primarily for the trade. The common denominator is that making barrels is all they do. THE STEEL. The barrel of any firearm is a pressure vessel with the action serving to stop up the rear end. The peak pressures involved during discharge are enormous, 50,000 pounds per square inch or more, and special steels are required to safely withstand these stresses.
