①Three-axis milling machine

Three-axis milling machines are the most basic type of equipment. The cutting tool is capable of movement in three linear X, Y and Z axes. Three-axis milling machines are popular because of their low cost and simplicity of operation. These machines also have lower maintenance requirements compared to multi-axis options.

②Four-axis milling machine

Four-axis milling machines can move in three linear axes as well as an additional rotary axis. The rotation axis can be any one of the A, B, and C axes. The A-axis rotates around the X-axis, the B-axis rotates around the Y-axis, and the C-axis rotates around the Z-axis. Due to the angular movement of the cutting tool, 4-axis milling machines can manufacture highly complex parts.

③Five-axis milling machine

Five-axis mill uses all three linear axes and any two rotary axes. A rotary table is often used to simplify the spindle axis complexity. Five-axis machines can manufacture complex parts at high speeds suitable for mass production.

As a leading provider of CNC milling and machining services and parts, 3ERP has 32 in-house 5-axis milling machines, allowing us to meet tight tolerances and produce complex geometries. For low cost parts we have 3 and 4 axis milling machines.

④Six-axis milling machine

Six-axis milling machines can move in all three linear axes and three rotary axes. This provides the ability to machine the work surface from all sides simultaneously without repositioning. six-axis milling machines provide high precision suitable for any requirement. The machine's production speed is sufficient for high-volume production.

A knee mill is a vertical milling machine configuration in which the table is mounted on a movable casting called a "knee." The knee can move vertically on the Z-axis. This enables the operator to adjust the vertical position of the workbench. Knee mills increase the versatility of milling machines in operations such as drilling.

frame mills have a fixed spindle and knee structure that can only move vertically (Z-axis). The X and Y axes are merged into the workbench. C-frame milling machines are used in mass production due to their high milling speeds.

Track-controlled milling machines use a replica of the final part to guide the milling machine. The probe scans the replica counter and guides the cutting tool to create a similar pattern on the workpiece. It also requires a lot of manual work to scan the copies using probes. Furthermore, it is a time-consuming and low-precision control system.
