Ⅲ.Our Products

4-Axis CNC PCD Tool Grinder BT-150D

The machine is suitable for massive production of carbide insert, PCD and CBN insert. Once centering is finished, grinding will be done automatically. The even consumption of grinding wheel can be measured and compensated by the system, so production with long cycle time can be measured.

BT-150J Superhard Tool Grinding Machine

BT-150J PCD Tool Grinder is reliable in performance and easy to be operated. It requests very little manual skill. The swinging of grinding wheel controlled by PLC is smooth and without reverse vibration. Without wheel handles it is easy to control the swing range, frequency, and swing position by pushing the button. The machine using ‘rapid feed’ and ‘precision feed’ to finish rapid feed/retraction (0.5mm/turn) and work feed(3mm/turn). This assures the production efficiency and feeds precision.

Drill Grinding Machine BT-40

Drill, tap, countersink cutter and step drill can be ground on BT-40 without extensive training. The vertical grinding wheel makes web thinning very easy. Six-jaw chuck with high accuracy guarantees the run-out a drill deserves.

BT-560 Tool Analyzer

The analyzer is used for measuring the geometric elements(such as the diameter, radius, and the cutting edge angle) of drills and cutters. It makes use of the tool microscope and CCD camera to magnify the image and realize the real-time display, and the operating lever and electronic handwheel to set the measurement position quickly and precisely.

BT-150E 5-Axis CNC Tool Grinding Machine

BT-150E 5-Axis CNC Tool Grinder is equipped with special CNC system, with tool grinding application software based on Windows XP. It can grind drills, end mills, and ball nose of HSS and carbide. All the programs can be saved, copied, renamed and modified. Before starting grinding the tool, 2D simulation can be made and confirmed, so proper adjustment is possible.

Ⅳ.Product Application

The production of BT150 series diamond tool grinding machine is suitable for massive production of carbide inserts, PCD and CBN inserts.
