Each axis of the CNC machinery has a linear system to move the vehicle to its desired location, includes Ball Screws or Rack and Pinion.

A rack and pinion is a type of linear actuator that comprises a circular gear (the pinion) engaging a linear gear (the rack), which operate to translate rotational motion into linear motion. Driving the pinion into rotation causes the rack to be driven linearly. Driving the rack linearly will cause the pinion to be driven into a rotation.

- Pros: 1. Cheaper to make. 2. Can be assembled together, thus more cost effective for long linear travels.
- Cons: 1. Top speed is lower. 2. Due to the gap between pinion tooth and rack tooth, it generally has lower re-positioning accuracy. 3. Higher power consumption and faster wear and tear due to its high inherent friction.

A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction. It's mostly seen on high-end products.

- Pros: 1. Higher top speed. 2. Close contact between ball bearing and the helical screw provides high re-positioning accuracy. 3. Little internal friction grants lower power consumption and much slower wear and tear if maintained properly.
- Cons: 1. More expensive to make. 2. Cost is prohibitive for long linear travels.

There are two options for a gantry-moving type CNC machine tool, move the entire gantry to save materials, or rise the base frame in z-axis to move the beam only. We offer both styles for B Series Gantry Mills:

By moving the entire gantry:
- Pros: 1. Easier to load / unload extremely large footprint workpieces. 2. Better visibility of workpieces. 3. Save steels proportional to machinery x-axis length.
- Cons: 1. More expensive (Manufacturing / Calibration / Maintenance). 2. Slower feed rate / top speed caused by the high center of gravity of the gantry vehicle. 3. Requires larger motor which results in higher power consumption.

By moving the gantry beam only:
- Pros: 1. Lower overall cost. 2. Faster feed rate / top speed as the center of gravity is low in respect of the beam. 3. Uses smaller motors thanks to the lighter gantry weight, which also reduces power consumption. 4. Much higher rigidity thanks to the U-shaped base frame.
- Cons: 1. Sacrifices visibility of workpiece. 2. Harder to load / unload extremely large workpieces. 3. Costs more steels to build.

In summary, for gantry type machineries, it is preferable to moving the beam. Only in extreme scenarios would you need a entire-gantry-moving CNC machine tool.

Generally, an Automatic tool changer or ATC is used to improve the capacity of the machine to work with a number of tools. It is also used to change worn out or broken tools. However, it is not always cost effective in following scenarios:

- The machining process only requires single tool, and the material is relatively soft so that the tool does not worn out quickly.
- The machining process only requires single tool, and the processing time is relative short.
- The machining process requires very few tools, and each tool is being constantly used for long period before changing out.

B Series is designed for rapid processing of PS Foam or any materials alike (with occasionally usage for processing wooden materials). For most applicable use cases, it only requires a single ball-nose tool during the entire manufacturing process. Hence, B Series CNC machine tools offer ATC as an optional feature.

Your Benefits

Your Business Will Benefit from Using B Series

Save time and money, improve processing quality and efficiency

Improves your mold/pattern making process by utilizing modern CNC technology. Save up to 75% of production time, gain better control over product quality, higher success rate, and reduce the total number of labors involved.

Boost throughput and cash flow, while shortening lead times

The complete machining of the CNC mill dramatically shortens the production process chain and simplifies production management and scheduling. The more complex the workpiece, the more obvious its advantages over the traditional process-dispersed production methods.

Shorten product development cycle

Slicing, gluing, nailing, un-nailing, assembling, and drying are necessary when developing new products traditionally, which is prone to cracks and misalignments. A CNC Mill is an excellent solution to the problems by reducing most of the processes, significantly shortening the development cycle, and improving the success rate of new products.

Redefine your overall capabilities

Compares to traditional approaches, our CNC technology effectively transforms digital drawings to actual assembly with fewer parts, thus raises the limits on the types of part geometries and dimensions you can provide. It unbridles the imaginations of you and your engineers to produce highly complex components in a larger footprint.
