​   Angle Heads

When to use an angle head: an angle head redirects machining-centre spindle power through 90° or any set angle, so a 3-axis machine can cut the sides and angled faces of a part without turning it over and without moving to a 5-axis machine. The most common cases are side holes and slots in mould tooling, cross holes in valve and pump bodies, and parts already located on the table that need one side operation but should not be taken off and re-clamped. What you save is not only time; concentricity and true position matter more, because finishing in a single setup means the tolerance is not run again at a second location. Four things decide selection: the spindle interface (BT / HSK / PSC and so on) and pull-stud spec; the space available at the cutting position, which decides between standard, extended and offset types; the torque and speed required; and whether through-tool coolant is needed. Mongtec angle heads use a modular interface design, so standard, extended, dual-head and adjustable-angle types can be combined to suit the job, and through-tool coolant is delivered through the locating pin. When an angle head is not the right choice: in heavy cutting and high-torque work its rigidity becomes the limit; if a small-diameter cutter needs very high rpm, a hydraulic speed increaser is the better answer; and where the bore or the space is too small for the bar to reach, feasibility should be checked first. Before requesting a quotation, please provide: the part drawing, machine brand and model with spindle spec, the space at the cutting position, tool spec and target rpm, workpiece material and batch size, and whether through-tool coolant is required.
