Floor Type Boring and Milling Machine

CBM-135P/CBM-135QF/CBM-150QF

High Productivity
Besides nose type headstock, the quill system ensures a good accessibility to the work.
Spindle continuously monitored to provide most efficient cutting conditions.
Each axis is independently controlled to provide maximum feed as required.

High Power Spindle
Variable speed and high torque are a function of the 30kw AC motor (30 min. rating).
The large-diameter quill provides high rigidity even with stroke extended creating stable cutting conditions.
For the spindle bearings, super precision, highly rigid tapered roller bearings are employed. These bearings ensure high precision and high rigidity of the spindle with minimal heat generation. The machine is equipped with a cooling device for the lubricant inside the headstock.
The spindle nose is a 7/24 taper No. 50. The tools can be automatically mounted or removed quickly without fail by the tool lock/unlock pushbutton switch located in front of the headstock.


High Positioning Accuracy through CAD designed rib casting.
For the vertical travel of headstock, the spindle travel and the quill feed, high quality ball screws are used. All sliding surfaces are automatically lubricated at key points.
The clamps for headstock vertical travel, column cross traverse, and quill travel are heavy-duty hydraulic type.
The major structural members are box-shaped with best possible arrangements of ribs with a large cross-sectional area, providing highest rigidity long-term accuracy and precision.

High Precise Slide ways
The column and bed slide ways are hardened and ground. The mating surfaces of the moving units are coated with a special fluorine resin, and forced-lubricated so that the system for slide ways offers minimum friction resulting in high precision which will be maintained over a long period of time, this ensures a very smooth feed stroke even at low speeds without stick/slip.

Easy Operation
The switches on the pendant control box have the most efficient layouts for working respectively. This ensures improved operating efficiency.
The contents of programs and the current positions are displayed on the CRT display. This enables to make preparation and checking of the programs easily.
Using the portable operation control box allows the work to be adjusted to be centered, and permits manual cutting operation.

Rotary Table
The bed slide way is hardened and ground, and equipped with an automatic lubricating system. This creates good abrasionresistance and long working life.
NC-controlled, the saddle feed (V-axis) is driven by high-precision ball screw to provide precise positioning capability.
With the rotation of the rotary-table indexed to every 90 degrees controlled by the M-command, the positioning pin provides high precision indexing. The digital read-out counter is standard equipment calibrated to 1 minute.
The use of B-axis Numerical Control as the optional specification is recommended. This enables high-precision desired indexing for each 0.001 degree and rotational milling.
