Please ensure that good quality of packing is provided, so that the same packing case can be re-used. If we find that the packing is not fit enough for re-use, we will use a fresh packing case at an extra cost. Kindly ensure that all the relevant dispatch documents (i.e.) copy of our Original invoice with the relevant Excise Gate Pass and your declarations etc. accompany the material while in transit to avoid any possible detentions by Central Excise or Sales Tax authorities at any of the Check Post en route. Please mention prominently the following to avoid any problems en route:
          ‘GOODS SENT FOR RECONDITIONING --------------------NO SALE
INVOICING INVOLVED----------------------      
CONSIGNEE’S C.S.T. NO.2003/67-68 Dated 08.01.1968.


REPLACING EXISTING CHUCK/CYLINDER - Is your existing chuck/cylinder of GMT make? If yes, give us the serial number engraved on the chuck body face. For cylinders please refer the metal label.   
Do you need to replace your chuck? Need a new Chuck 
We have been in the business of workholding for more than 5 decades in India. We have supplied over 55000 chucks to the Indian Manufacturing Industry. This has provided us with a valuable insight into the usage, maintenance and replacement of workholding products. Many a time we have come across GMT and imported chucks being replaced by cheaper brands. This leads to a loss of quality production and money in the long run. 
If it is of other make or if you are unable to give us the serial number, please provide us with complete spindle details along with the make and model of the machine.

Berg Clamping systems Tool Clamping - HK / HKR

Clamping sets of the type HKR are designed for clamping hollow shank tools according to DIN 69893.
Design features
HKR clamping sets have six collets held by an annular spring which allows a rocking movement for inserting and removing the hollow shank tools. During clamping the taper of the centrally positioned draw-bolt increases the actuation force, thereby generating a much higher clamping force at the collets. The special tribolic coating guarantees the highest possible constant clamping force. The clamping set is maintenance free. A locking bolt permits infinitely
variable positioning and fixation of the clamping set in the Z axis. No special tools are required for assembly and disassembly. The spindle has an easy to produce interior contour. The HKR-gripper has a built-in snap-hold feature allowing a toll to be hold securely in the spindel even in unclamped position.
Ordering example
HK 38
HKR 38
Delivery scope
Clamping set according to data sheet
When clamping without a tool the draw-bolt of the clamping set is supported at the end of the total stroke hT in the depth ‘m’ inside the spindle. If no possibility for the stop is provided at this point, it has to occur at a different point.
