Cast Iron Bench Center

Backed by a team of experts, we are offering a qualitative range of cast iron bench centers that are accurate and quick method for inspecting radial run out of camshafts, crankshafts and cylindrical shafts. Manufactured as per IS: 5980-1978, these cast iron bench centers are utilized in machine shops, tool rooms and standard rooms for checking various parameters such as concentrically , parallelism and true rotation of components. The bench centers manufactured at our works are made up of close grained cast iron and finished to higher degree of accuracy by hand scrapping.


Some of the salient features of our Bench centers are:


  • The base of bench centers and its heads are artificially stress relieved as precaution against distortion
  • One of the center is spring loaded to ensure uniform pressure while holding and easy loading and unloading of work piece without disturbing the accuracy.
  • Centers are made from high carbon steel hardened and ground finish, having more taper MT-3 and are replaceable.
  • Both heads are adjustable to the required positions, easy and quick setting of the required distance between the centers.
  • The heavy duty bed is provided with two T-Slots, parallel to each other
  • Our range of Bench centers are supplied with  computerized calibration certificate traceable to National Physical Laboratory (NPL, Govt of India) New Delhi.

Luthra vertical bench centre is ideal, accurate and quick method for inspecting radial run out of camshafts, crankshafts, cylindrical shafts. Gear teeth run out can also be inspected by using mandrel, arbour or directly to the centre. Luthra vertical bench centre is ideally suited in machine shops , tool rooms and standard rooms for checking various other parameters like  concentrically and true rotation of components in vertical position.


Some of the silent features of Vertical bench Centre are:


  • Base of bench centre is made of close grained castings and finished to high degree of accuracy by hand scrapping.
  • The base of bench centre , column and its head are artificially stress relieved as precaution against distortion.
  • One of the centre  is spring loaded to ensure uniform pressure while holding work piece and unloading without disturbing the accuracy of centres.
  • Centres are made from high carbon steel hardened and ground finish having more taper (MT-3) and are replaceable.
  • One head is adjustable to the required  positions for easy and quick setting of the required  distance between the centres and other centre is fix  mounted on base.
  • The heavy duty dove tailed column is provided  with  rack and pinion arrangement along with counter weight for smooth movement of spring loaded head.

Mini Bench Centre Granite Base

Mini Bench Centre Granite Base
Mini Bench Centre Granite Base
Granite mini bench centre is made of black granite base which is naturally seasoned and  provide better finish and accuracy. T-slot made of steel is fixed within granite base on which two cast iron heads are mounted, both the heads can be moved to the desired  positions depending upon the size of component to  be checked. One of the mini bench centre is spring loaded to ensure uniform pressure while holding work piece and easy loading and unloading without disturbing the accuracy of the centres.

Luthra Granite mini bench centres are specially designed  for checking concentrically, parallelism and true rotations of components having smaller dimensions. These are widely used in industries manufacturing smaller CNC turned automobiles parts, watch spares and microscopic parts etc. where higher accuracies are required. Centres are made from high carbon steel hardened and ground finish, having morse taper MT-1 and are replaceable.

Cast iron heads are artificially stress relieved to avoid distortions. Granite base have outstanding advantages over cast iron base.

  • Hardness uniformity.
  • Accurate under load conditions.  
  • Vibration absorbent.
  • Easy to clean.
  • Rustproof ,Noncorrosive.
  • Thermal stability.
  • Wrap resistant.
  • Low porosity.

Each Luthra granite mini bench centre is provided with computerised calibration certificate traceable to NPL (Govt. Of India)
