CNC Machine Tool Holder Hydraulic Tool Holder BBT40 HDC20 Hydraulic Chuck

BBT40: Double fitting of conical surface and flange end face, greatly improving rigidity and high-speed stability. It can only be used with BBT40 spindle and cannot be installed with ordinary BT spindle.

HDC=Hydraulic Chuck: Hydraulic expansion tool holder (hydraulic tool holder), relying on internal high-pressure oil to evenly clamp the tool.

Complete model example: BBT40-HDC10-90

HDC10: Clamping standard tool diameter of φ 10;

90: The total overhang length of the handle is 90mm.

Core performance parameters

1.Jumping accuracy

The radial runout at 4 times the diameter of the tool is ≤ 0.003mm, and the repeated clamping accuracy is ≤ 1.5 μ m, far exceeding the ER tool holder. It is suitable for high-precision drilling, reaming, and precision milling.

2.clamping range

Standard specifications: HDC03/04/06/08/10/12/16/20/25/32, capable of holding straight shank cutting tools with diameters ranging from 3 to 32; Paired with a variable diameter sleeve, it can cover smaller diameters.

3.dynamic balance

Factory pre balancing G2.5@25000rpm Suitable for high-speed precision machining of molds and five axis machines.

4.Cooling and Structure

Built in center outlet, with a maximum pressure resistance of 80 bar; Sealing, dustproof and waterproof hydraulic chamber; Only one T-shaped hex wrench is needed for locking, and the operation is simple.

5.Requirements for tool handle

H6 tolerance straight shank cutting tools must be used, as any impact on the shank will directly damage the clamping accuracy.

Applicable processing scenarios

1.Mold processing: deep cavity corner cleaning, high-speed milling of curved surfaces, precision machining of high hardness steel;

2.Precision hole machining: hard alloy drill bits, replaceable head drill bits, reamers, countersunking;

3.Five axis machining center: slim HDC type interference avoidance, multi angle precision cutting;

4.Heavy duty milling of aluminum alloy/stainless steel: hydraulic damping for shock absorption and vibration suppression.

Precautions for use

1.Only compatible with BBT40  spindle, ordinary BT40 spindle cannot be used, forced installation will damage the spindle end face;

2.Clean the inner hole of the handle and the handle of the tool before installing it, as impurities can cause excessive jumping;

3.Prohibit oversized and bold cutting tools to avoid permanent deformation of the hydraulic chamber;

4.Long term idle, replenish dedicated hydraulic oil every six months to prevent oil leakage and pressure loss.
