Frequently Asked Questions (FAQ)
Q
What is the drive ratio of the HSK Angle Head DG90 Series?
The standard HSK Angle Head DG90 Series uses a 1:1 drive ratio. Some special models, such as those with ER25H collet, support a 1:2 ratio, and tapping heads use a 2:1 deceleration ratio. The CA SGM series offers both 1:1.06 (acceleration) and 1:0.77 (deceleration) options depending on the model.
Q
Is a Stop Block required for mounting the HSK Angle Head?
Yes, a Stop Block is required when mounting the HSK Angle Head on machines. It must be ordered separately. The Stop Block also enables cooling liquid to reach the cutting edge through the tool body. Please note that Stop Blocks may differ for various brands of machines.
Q
Does the HSK Angle Head DG90 Series support auto tool change?
Auto tool change might be unavailable for some machines. It is recommended to verify compatibility with your specific machine model before purchasing. Please consult with our technical team if you need guidance on machine compatibility.
Q
What is the difference between the Standard and Powerful versions of the HSK Angle Head?
The Powerful version is designed for heavier cutting loads and generally weighs slightly more than the Standard version due to reinforced internal components. Both versions share the same external dimensions and fix distances, making them interchangeable in most setups. The Powerful version also supports different fix distances (80mm or 110mm) on HSK100A models.
Q
Are collets included with the HSK Angle Head DG90 Series?
Collets are not included and must be ordered separately for most models. Wrench and nut are typically included. For Lightweight and Out-Internal Cooling (ODG90) series, an oil sealed clamp nut is also required and must be ordered separately. Please refer to the specific model's feature list for exact inclusions.
Q
What coolant options are available for the HSK Angle Head DG90 Series?
All HSK Angle Head DG90 Series models are non-central coolant. Cooling liquid can reach the cutting edge from the tool body when routed through the Stop Block. For the Out-Internal Cooling (ODG90) series, the tool is specifically designed for drilling with cooling and must not be used without coolant. The Double Head (180°) series supports cooling tube connection at PT1/8 port.
