Description
The CNC tapping center, designed and manufactured by VALMER, is your best choice in drilling and tapping work. The machine series employs a high speed traverse on three axes to significantly increase drilling and tapping efficiency. In addition, customers may select armless or arm type magazine according to machining requirement. The entire machine is ruggedly constructed to assure the highest machining accuracy.
- The structural parts of the machine are manufactured from high quality MEEHANITE cast iron, rib reinforced and stress released to assure it remains deformation-free year after year.
- Three axes slideways are mounted with precision linear ways. Extra-large span between ways. High feed rate and superior stability.
- Servo motor directly drives ballscrew, featuring high positioning accuracy without backlash problem.
BT-40 Direct Drive Spindle
The directly coupled spindle eliminates power transmission loss to develop the highest efficient of spindle motor. Spindle is mounted on four P4 high precision angular contact ball bearings, combined with constant temperature device to provide outstanding richening rigidity.
Coolant Through Spindle
Coolant flow is fed by a high pressure pump through the spindle and out the tip of the cutting tool, immediately reducing any heat at the cut point. This substantially increases the cutting efficiency while extending tool life, this system reduces thermal deformation and provides stable accuracy.
Z axis Telescopic Guard
To conform high speed traverse of Z axis, it provides superior protection for linear ways and extends their service life.
Linear Ways on 3 Axes
The X, Y, Z axis slidways are mounted with precision linear ways, fitted with great span between ways, showing maximum stability during high speed traverse. The ball type linear ways feature low friction coefficient and high positioning accuracy.
Large Capacity Coolant Tank with Casters
Sliding coolant tank can be pulled out easily while coolant pump with mesh filter take away cutting chips quickly.
Chip Auger
A chip auger is mounted at the center of the base, removing chips to the rear side of the machine easily. It makes chip disposal convenient.
X, Y Axis Telescopic Guard
The telescopic guards on X, Y-axis prevent chips or coolant from damaging linear ways.
“V” shaped telescopic guard on X, Y axis allows fast chip removal and high efficiency linear way protection.
