NEW! The FlexArm B-33

Flex Machine Tools is excited to introduce a new offering to its line of ergonomic balance arms: the FlexArm B-33.

The B-33 balance arm is a larger model of the FlexArm B-19, both designed for counterbalancing the weight of tools. The B-33 has a longer reach and greater counterbalance weight capacity. This model is excellent for customers who are looking for an ergonomic balancing solution with maximum range and flexibility.

This balance arm has two areas of 360° rotation, allowing it to operate freely on multiple planes: top-down, in and out, and left to right. The standard B-33 is available with a vertical v-block tool mount or with a rotational gimbal (B-33-RG), which adds the advantage of rotating the attached tool during use. 

The B-33 with vertical v-block tool mount has a counterbalance capacity of 1-40lbs, a 10”-53” working range, and the v-block fits tool diameters of 1.00″ to 2.25″.

Both versions of the B-33 have a precision air regulator that controls the counterbalancing, making it easy to switch between tools of different weights with a twist of the knob. Shown below are the counterbalance weights with corresponding PSI for the B-33 with vertical v-block.

The B-33-RG with rotational gimbal adds even greater reach and the advantage of being able to rotate the tool during use. The counterbalance capacity is 1-25lbs and the arm has an impressive 72” working range. The rotational gimbal on the B-33 is great for counterbalancing angle grinders, vertical grinders, and horizontal grinders. This version of the B-33 can counterbalance up to a 25lb tool at 105 PSI and provides complete freedom of motion. The large selection of gimbal options can fit tool diameters from 0” to 5.375” and most vertical grinders. The clamp plates for each rotational gimbal are made specific to the tool body profile for a secure hold.

The FlexArm B-33 offers the greatest reach and counterbalance weight capacity of any FlexArm balance arm. For those who need this additional range, or those looking for a versatile balance arm with customizable mounts, the FlexArm B-33 balance arm is right for you!

    Good Morning,
    Can these arms be designed to mount on various platforms and or equipment such as JLG lifts?
    we work on large haul truck frames, dippers, clams where our welders are using grinders sometimes for hours even days at a time. If i could get some options and possible a few quotes i could use to present to my management team, it would help me in presenting a case that we would benefit from having these flex arms throughout the shop.

Auto Stand-Off – This is currently defined to be surface stand-off and not to be confused with vector stand-off in 5-axis mode. The current auto stand-off is based on a changing surface and will adjust vertically based on the angle of the “A” Axis, so there is five (5) axis taken into account during the calculations, but this is not the same as the tool vector stand-off. There is the ability to do the vector stand-off change while the machine is running manually with buttons on the screen.

Z-Reader Probe – The Z-Reader is a device for mapping the location of the surface. It can be controlled manually & programmatically. The option is NOT active while cutting & is retracted out of harm’s way. It can be triggered to verify the surface at every pierce before the cutting process starts, or it could be used to drive surface mapping of the whole part before cutting starts. It begins with initialization or zeroing of the device to the surface at the beginning of a program and then accumulates or tracks the difference from that zeroing effort.

Automatic Edge Finder – The edge finder is or can be utilized manually (Jogging Method & Screen Buttons), programmatically (M & G codes), or fully automatic routine (dedicated program). This option sets offsets & program rotation to match the orientation & location on the cutting table.

AC Unit Installed on Electrical Cabinet – The unit is mounted on the cabinet’s High Power (480v) side. It is close to the location where the drives are mounted. This option keeps the cabinet temperature stable and allows heat dissipation faster. The servo drives for all axes are the most significant contributors to heat inside the electrical cabinet.

5-Axis Renishaw CalibrationThe calibration unit is a Renishaw model APCA45 with a modified spherical stylus. The device has a retractable cover and air purge to clear debris & dust during the activation process. It mounts to a swing arm controlled by a pneumatic rotary, so it is out of the way during regular operation and swings into the calibration position for calibration only.
