Precision live centers with replaceable inserts and special push-off nut

  • Possibility of using centers during machining or measuring.
  • Replaceable inserts expand the possibilities of using centers.
  • Possibility of using centers on CNC machine tools and grinders.
  • Special seals prevent the ingress of process liquid and dust particles.

Technical details of the product

 

The centers are designed for centering and clamping workpieces on classic NC and CNC lathes. Their clamping part allows easy access of the tool to the workpiece, which is advantageous - when machining shaped parts.

 

The construction of the centers allows adjustment of the clearance in the front radial bearing. The live centers are provided with a shank with morse taper shank according to ČSN standard ISO 296. Replaceable inserts enable universal use for production of various single workpieces. Depending on the used replaceable insert - the workpieces can be clamped in different ways - for example at the inside diameter of pipes, etc.

The rotating part of the live center is provided with a conical cavity and therefore various clamping inserts can be inserted as needed. The inserts must be pressed into the cavity with a clamping force (tailstock). The clamping insert  can be removed with help of a special punching fork. In addition to the use of replaceable inserts, the live center is equipped with a special pusher nut for easy removal from the tailstock of the machine. A special sealing ring prevents the ingress of process liquid and dust particles into the bearing spaces of the live center - which significantly extends its durability.

The live centers are supplied with special lithium-based grease - Mogul LV2-WR. Disassembly of the live centers - except for authorized service - is not recommended.

  • Set of 60 ° and 90 ° inserts expanding the production portfolio of workpieces.

Technical details of the product

 

These live centers are designed for turning operations where is necessary the workpieces clamping with cavities of large diameters, which cannot be clamped with live centers of the conventional type.

 

The rotating part of the live center is ended with a special taper - which enables to fit clamping insert with an angle 60 ° (U1) or 90 ° (U2) as needed. In the basic version, the live centers are supplied with one set of replaceable clamping inserts corresponding to the MT size.

In the standard version, the live centers are supplied with inserts as required with a maximum Ø of D according to the table. In a special design, non-disassemble live centers are also supplied - the clamping inserts cannot be removed. The special clamping inserts are also supplied as spare parts. The live centers are provided with a Morse taper shank according to ČSN standard ISO 296.

The live centers are supplied with lithium-based grease Mogul LV2-WR. Disassembly of the live centers - except for authorized service - is not recommended.

ČSN 24 3324

Precision live centers with crest angle 60°

  • Special seals prevent the ingress of process liquid and dust particles.
  • Possibility to use the live centers on grinders.

Technical details of the product

 

The live centers are designed for workpieces clamping on lathes. Alternatively - for work on grinders, especially when grinding of heavy workpieces.

 

The construction is characterized by a small diameter of the head Ø D, allowing easy access of the tool to the workpiece. For live centers with a Morse taper 2 ÷ 6 is the clearance adjustment in the front radial bearing very advantageous. The MT 1 live center is of a different construction and is designed for very light workpieces clamping - therefore we do not state the permissible load of this product. The live centers are equipped with a shank with a MORSE taper according to ČSN standard ISO 296..

The live centers are supplied with lithium-based grease Mogul LV2-WR. Disassembly of the live centers - except for authorized service - is not recommended..

ČSN 24 3325

Precision live centers for heavy workpieces clamping with head angle 60° or 90°

  • A special seal prevents the ingress of process liquid and dust particles.
  • Possibility of implementing special designs according to customer specifications.
  • Option to two accuracies - Normal and Extra.
  • Possibility to use the live centers on grinders.

Technical details of the product

 

The live centers are designed for heavy workpieces clamping on lathes. Very rigid construction and robust bearing of the rotatable part are characterized by very high durability.

 

The advantage is the possibility of adjusting the clearance in the front radial bearing. The bearing spaces are filled with OL-J5 oil. The live centers of the category EXTRA precision are also used to clamp workpieces on grinders. To reduce deformations of the machine (tailstock, carriage, headstock) due to axial clamping forces, we supply the live centers with a head angle of 60 ° which is especially advantageous for machines loaded in the range of the permissible maximum.

The live centers are provided with a taper shank Morse 4 ÷ 7 according to ČSN standard 22 0420 or METRIC (Me) shank according to ČSN 22 0410. The shanks comport to DIN 228 and ISO 296. Disassembly the live centers - except for authorized service - is not recommended.
