Mold Making 5 Axis CNC Machine
It combines three linear axes (X, Y, Z) with two rotary axes (A/C or B/C) to machine multiple surfaces and deep cavities in a single setup, reducing repositioning errors.
This machine is typically selected when mold components contain angled surfaces, intersecting geometries, or deep cavities that cannot be accessed with conventional 3-axis machining.
Description
Technical Parameters
Working Principle
Workpieces are fixed on the rotary tilting table using vises or custom fixtures. The spindle rotates the cutting tool while servo motors move the tool along programmed paths.
Process flow:
Rough milling removes bulk material from mold blocks.
Semi-finishing defines cavity geometry and angled surfaces.
Ball nose cutters machine contours, corner radii, and undercuts.
Drills create mounting holes.
Taps form threaded holes for assembly.
Finishing cutters produce final dimensional surfaces.
Rotary axes allow cutters to reach angled and internal surfaces without repositioning the workpiece. Coolant removes heat from the cutting zone, and chip conveyors transport debris from cavities to collection containers.
Rotary Table System
The rotary tilting table provides access to multiple surfaces during a single setup.
Rotates and tilts the workpiece along A/C or B/C axes.
01
Maintains tool engagement on deep cavities, angled surfaces, and mold cores.
02
Supports tooling blocks, mold inserts, and electrode blanks of defined size and weight.
03
Rotary axis calibration is required periodically to maintain dimensional accuracy.
04
Materials Processed
- Metal: P20 Steel, H13 Steel, S136 Stainless Steel, Aluminum Alloy, Copper Alloy.
- Non-metal: Graphite, PEEK, Epoxy Tooling Board, Engineering Plastics.
Cutting parameters (feed rate, spindle speed, depth of cut) are determined according to hardness, geometry, and tool type.
Cooling and Chip Management
Coolant is delivered through external nozzles or through-spindle channels to remove heat and flush chips. Chip conveyors remove steel and aluminum debris. Graphite applications often rely on dry cutting and dust extraction.
Installation Requirements
Reinforced concrete foundation capable of supporting machine weight and cutting loads.
Industrial power supply and compressed air connection.
Coolant circulation system and chip collection setup.
Controlled ambient temperature to reduce thermal expansion affecting machining precision.
Typical Applications
Injection mold cavities
Die casting molds
Mold cores and inserts
Sliders and lifters
EDM electrode production
Precision mold tooling components
This machine is selected when multiple surfaces, deep cavities, angled features, and continuous machining in a single setup are required.
FAQ
Q: What types of mold materials can this machine process?
A: It machines P20, H13, S136 mold steels, aluminum alloys, copper, graphite, and epoxy tooling boards. Cutting parameters depend on material hardness and tool diameter.
Q: How does it reduce machining setups?
A: The rotary tilting table rotates and tilts the workpiece, allowing cutters to access angled surfaces and deep cavities in a single setup, minimizing repositioning errors.
Q: What are the spindle specifications?
A: Spindle speed and torque vary by material. Higher speeds are used for graphite, while mold steels require lower speed and higher torque. Cooling maintains bearing temperature during continuous operations.
Q: What installation requirements must be met?
A: A reinforced concrete foundation, industrial power, compressed air, coolant circulation, chip collection, and stable ambient temperature are required to maintain dimensional accuracy.
Q: How is maintenance handled?
A: Daily maintenance: clean chips, spindle taper, and check coolant and lubrication. Periodic maintenance: calibrate rotary axes, inspect ball screws, guideways, spindle runout, and tool changer function.
