INTSUPERMAI vs INTBUYING Milling
Motor Wattage
The INTSUPERMAI model lists a 1300W brushless motor, while the INTBUYING unit specifies 1.5HP. In watts, 1.5HP converts to approximately 1119W. This means the INTSUPERMAI has a higher rated power input on paper. Both machines use brushless technology, which typically offers longer life and less maintenance than brushed alternatives. The INTSUPERMAI adds overload and overheat protection to its electrical system. The INTBUYING motor is described as handling drilling up to 25mm and face milling up to 63mm. Higher wattage often supports heavier cuts in metalworking. You should consider if your specific projects require that extra power reserve or if the 1.5HP rating is sufficient for your typical workload.
Digital Readout
Precision positioning is a key differentiator here. The INTSUPERMAI includes a built-in 3-axis grating ruler with a digital readout system claiming 0.005mm accuracy. It also features power failure memory and coordinate calculation modes. The INTBUYING specifications do not mention any digital readout or electronic measurement aids. Without a DRO, you must rely on manual scale markings on the machine columns and tables for positioning. This makes the INTSUPERMAI significantly better for tasks requiring high repeatability and fine adjustments. If you plan to do detailed metalworking or intricate crafting, the digital feedback on the INTSUPERMAI reduces manual measuring errors. The INTBUYING relies on traditional mechanical gauges.
X-Axis Feed
Both machines offer an automatic power feed for the X-axis, which saves manual labor during long milling passes. The INTSUPERMAI specifies stepless forward and reverse auto feed options. It also notes that the spindle micro feed handle auto-rebounds after release. The INTBUYING mentions a variable speed range and flexible spindle but does not detail the specific nature of its automatic feed mechanism in the provided specs. While both likely provide automated table movement, the INTSUPERMAI gives more explicit details about the feed control logic. This can affect how smoothly you can control the cut depth and speed without constant manual adjustment. For users who mill frequently, stepless control offers finer tuning.
Spindle Speed
Both the INTSUPERMAI and the INTBUYING share an identical spindle speed range of 50-2250 RPM. This wide variable speed range allows you to use different tooling and materials effectively. Lower speeds are suitable for larger diameter cutters or harder metals, while higher speeds work well for smaller drills or softer materials like wood and plastic. Since the ranges are the same, there is no performance advantage for either brand in terms of speed versatility. You can achieve similar results in both machines regarding rotational velocity. The choice between them will not depend on the ability to reach specific RPMs for your project type.
Head Tilt
Both milling machines feature a head that tilts ±90 degrees. This specification allows for chamfering, inclined hole drilling, and special angle milling tasks. The INTBUYING adds that the spindle also rotates 360 degrees, providing additional flexibility for positioning. The INTSUPERMAI also supports this tilting function for angled work. Since both units offer the same ±90 degree tilt range, they are equally capable of handling angled operations. The 360-degree rotation mentioned for the INTBUYING is a standard feature for many R8 spindle heads to allow for different tool orientations. Neither machine has an advantage in this specific mechanical capability.
Choose your ideal milling machine
Precision-focused machinist needing DRO
The INTSUPERMAI includes a built-in 3-axis grating ruler with 0.005mm accuracy. This digital readout system features power failure memory and absolute mode switching. You avoid manual measuring errors and improve precision efficiency for metal or craft parts. The micro feed handle auto-rebounds, offering tighter control than the standard INTBUYING model which lacks this digital feedback system.
User wanting maximum power output
The INTBUYING specifies a 1.5HP brushless motor, which converts to approximately 1119W. While the INTSUPERMAI lists 1300W, the INTBUYING unit is marketed for robust power handling drilling up to 25mm and face milling up to 63mm. If you prioritize the higher horsepower rating for demanding metal working tasks, this model offers that specific advantage in its published specifications.
Maker needing flexible spindle rotation
The INTBUYING spindle rotates 360° in addition to tilting ±90°. This full rotation provides exceptional flexibility for angle drilling and milling tasks. The INTSUPERMAI head tilts ±90° but does not list a 360° rotation capability. If your projects require the spindle to pivot completely around its axis for specific setups, the INTBUYING design supports this movement directly.
Buyer prioritizing table size and feed
The INTSUPERMAI features a larger integrated cross table measuring 27.5" x 7.1". It also includes stepless forward and reverse auto feed for the X-axis. This automatic feed saves manual labor during long milling runs. The INTBUYING table is smaller at 7" x 27-1/2" and does not mention an automatic power feed system. For larger workpieces, the INTSUPERMAI table offers more surface area.
