Graphite Milling Cutter Application Cases

Graphite Milling Cutter Application Cases

Due to their rapid discharge rate, light weight, excellent thermal stability, and ability to be formed into complex geometries, graphite electrodes are increasingly being chosen by mold manufacturers as the material of first choice for electrode production. At the same time, because the properties of graphite and its machining principles differ from those of metals, machining graphite not only places higher demands on cutting tools but also requires significantly different machining strategies compared with conventional copper electrodes. Consequently, achieving efficient machining of graphite electrodes presents a substantial challenge for customers. Nanjing Jianchuan Shi has extensive experience in graphite machining, and JianShi is committed to helping customers improve the efficiency of their graphite electrode machining processes, thereby fully leveraging the advantages of graphite electrodes in mold design and product manufacturing.

Four-Axis Rotary Table Tooling Case

Four-Axis Rotary Table Tooling Case

A CNC rotary table is a machine tool accessory featuring a rotatable worktable used to clamp workpieces and achieve rotary and indexing positioning; it is commonly referred to as a rotary table or the fourth axis. Based on function, rotary tables can be classified into two main types: general-purpose rotary tables and precision rotary tables. It serves as an essential accessory for boring machines, drilling machines, milling machines, and broaching machines, among others, and is used to machine holes, slots, and inclined surfaces that require indexing. During machining, rotating the worktable enables the production of curved surfaces and arc-shaped slots. General-purpose rotary tables, in turn, are further categorized according to their structure into horizontal rotary tables, vertical–horizontal rotary tables, and universal rotary tables.

Application of End-Face Annular-Spray High-Performance Tool Holders in HPC Milling

Application of End-Face Annular-Spray High-Performance Tool Holders in HPC Milling

To effectively address the machining challenges posed by these “difficult-to-machine materials,” Diebold has specially developed the UltraJet™ 3.0 face-ring, high-force collet. This new UltraJet™ 3.0 high-force collet is an innovative combination of the JetSleeve™ 2 collet—marketed for many years—and the UltraGrip™ 3.0 face-ring, high-force collet. Designed specifically for HPC milling, it delivers high cutting speeds, extremely high cutting forces, low runout, ultra-high clamping force, and superior cooling performance. As a result, it effectively resolves common issues associated with hard materials such as titanium and nickel-chromium alloys, including poor chip evacuation, frequent tool breakage, low machining efficiency, and poor surface quality when machining deep holes and deep cavities.

Applications of RTCP Ballbar/Probe for Five-Axis Machine Tools

Applications of RTCP Ballbar/Probe for Five-Axis Machine Tools

RTCP, in high-end five-axis CNC systems, is understood as Rotated Tool Center Point—commonly referred to as the tool-tip-following function. In five-axis machining, when aiming to precisely control the tool-tip trajectory and the relative orientation between the tool and the workpiece, rotary motions introduce additional motion at the tool tip. Because the CNC system’s commanded tool-center point often does not coincide with the actual tool tip, the system must automatically compensate for this offset to ensure that the tool tip follows the prescribed trajectory as instructed. Within the industry, this technology is also known by other names such as TCPM, TCPC, or RPCP. In essence, all these terms refer to functions with similar capabilities to RTCP; strictly speaking, RTCP is specifically designed for dual-tilt-head configurations, where compensation is performed using the rotation center of the tilting head. By contrast, functions like RPCP are primarily used on machines with dual-rotary-table setups, compensating for changes in the linear-axis coordinates caused by workpiece rotation. Ultimately, however, these functions serve the same fundamental purpose: to maintain a constant relationship between the tool center and the actual contact point between the tool and the workpiece surface.
