ACRA MODEL 5VL HEAVY DUTY BED TYPE VERTICAL BORING & MILLING MACHINE

• Full Geared Drive Spindle with 2-ranges variable speed, powerful and easy operating
• Table Feeding System equipped with precision ball screws and powerful servo motor ensure the table movement smoothly.
• The X, Y, & Z Axis equipped with pneumatic clamp device.
• The X-Axis could be extended up to 2500 mm with 2 sub-slide way on request.

Table & Saddle:
• The Table and Saddle are made of high-quality cast iron which has been carefully stress relieved.
• Way surfaces are hand scraped and finished

Feed Box:
• Table and Saddle feed can be driven by power or manual operation, and is easy to change speeds and to operate.
• Because of the large range of speeds, it is simple to go from low speed heavy cutting to high speed
finishing cutting.

Backlash Eliminator:
• Table feed system is equipped with easy adjustable backlash eliminator to increase operating stability and cutting efficiency.
• Large supporting surface and narrow square guide ways provide stable and smooth sliding.

Accuracy of Table & Saddle:
• Table and saddle are made of high quality cast iron, treated through stress relieving.
• The sliding surfaces are scrapped and finished.
• The upper, rear and front reference surfaces are ground, T-slots are correctly machined. So that the flatness, parallelism and squareness all meet the requirements of operation and are convenient in setup the work pieces.

Operation Device:
Whole structure of the machine is quite simple.
The operation device, such as the switch and handle, are installed in the front of the machine, so that all functional operations are at the operator’s fingertips.
A Counter Balancing weight is housed in the column to guarantee the smooth travel of the spindle head.

Anti-Wear Surface:
• Casting by high quality case iron.
• Completed annealing process to release residual stress, and all sliding ways hardened and ground to reserve high accuracy and wear resistance.
