The use of hard materials for machine-tooling, such as tool steel, D2 hardened steel, and H13 hardened steel, is considered to be a difficult undertaking by a large number of precision engineers.
CNC drilling is not possible to use a standard Micrograin Carbide substrate for this application due to the nature of hardened steels HRc 50-70 due to their hardness. Dry machining, in addition to being extremely hard, is typically used to reduce heat fluctuations on the cutting tool, which makes this a particularly difficult application to master.
Aside from that, the tool's life may be unreliable, resulting in a subpar final product. Because of the toughness of the carbide substrate, it is more forgiving than other materials, allowing CNC milling service to be used at slower cutting speeds than other materials.
Hardened steel milling and turning can be accomplished without the use of coolant, which will result in longer tool life and greater consistency, respectively. Most engineers find this completely counter-intuitive to their expectations because they were taught in college that the more lubrication there is, the better the engine performs. In extreme conditions, tool coatings on hardened steel tools, such as those found in our X5070 cutters, can withstand temperatures that are many times higher than those generated when cutting dry, allowing them to be used.
Hardened steels can be milled with tools having diameters of up to 200mm, in other words.
CNC milling service is necessary to have a specific cutting edge geometry when working with hardened steels, but is this necessary?
Among other things, hardened steel tools have characteristics such as a negative land, shallow chip pockets, and a thick core that are typical of hardened steel tools. The design for high-speed machining with small depths of cut is made possible by the use of this type of geometry, which is not only extremely strong but also advantageous.
Both ER chucks and side lock arbors are designed to address the following two issues:
A variety of tool holding options are available from Cutwel in order to accommodate high-performance cutting tools for hardened steels, including the following:
Various applications can be carried out with hydraulic chucks, which are available in a variety of sizes.
Another one of my all-time favorite pieces of music has been added to my collection! Although hydraulic chucks are capable of achieving 3 micron run out and balancing at speeds of up to 25,000RPM, they also have the additional benefit of tool dampening, which makes them an excellent choice for high-speed applications. When comes to vibration reduction, long length tools have a significant advantage over shrink chucks because the vibration is significantly reduced.
The Korloy GSK collet chuck and the Cutwel HP3 slim chuck are the most popular tool holders available because of their versatility and cost-effectiveness, respectively. In several ways, they outperform ER collets, including a 5 micron run out margin, slimmer nuts, and a higher clamping force than ER collets, among other things.
The taper angle of the collet of GSK chucks is eight degrees, as opposed to the sixteen degrees of ER collets. This is a significant difference between the two types of collet taper angles. This eliminates the deflection and vibration that are commonly associated with ER collet chucks, allowing them to operate more efficiently as a result of their design.
