Automatic loading and unloading attachment is convenient to operate and reduce cost. The main features are as follows¡G
- The grinding and regulating wheel spindles are made of high quality alloy steel (SNCM-439), and treated through: normalized, tempered, carburized hardening, sub-zero treatment, and then follows the precision grinding process which can greatly enhances spindle life and stability guaranteeing deformation free performance.
- The unique hydrostatic bearings of the grinding wheel and Roller and Ball Bearing of regulating wheel can reduce the metal friction.
- The machine base is manufactured from high quality Meehanite cast iron and analyzed by advanced Finite Element Method (FEM). Along with vibration stress release, these outstanding structural features assure high strength, maximum damping capability, and longer service life.

Centerless grinding involves the workpiece being simultaneously machined and guided on its generated surface. The line contact on a grinding wheel forms the grinding line, the workpiece lies flush with the regulating wheel and is held in place from below by a guide rail.
During grinding, the center of the workpiece lowers as its diameter is reduced through abrasion. This causes the workpiece to migrate towards the regulating wheel. JUNKER’s electronic control system compensates for this position change by tracking the grinding wheel so that precise machining is guaranteed at all times.
Centerless cylindrical grinding is also the ideal solution for workpieces that are difficult to hold due to their shape or small dimensions.

JUCENTER 6L
Cost-effective grinding
The high-performance CBN grinding machine JUCENTER enables you to grind crankshafts, gearshafts and camshafts in one machine with the shortest possible cycle time. The JUCENTER combines two machines with complementary machining potentials into one. Instead of linking separate grinding machines for various machining tasks, the two grinding processes, i.e. grinding bearings and cams on camshafts, occur in two separate clampings on a single machine. This concept creates a wealth of benefits, the result being extremely cost-efficient grinding with optimised accuracy.
The technical concept
JUCENTER enables two machining technologies on one machine: Station 1 is usually for controlling cylindrical grinding with grinding wheel set (e.g. grinding bearing seats on camshafts or main bearings on crankshafts). Station 2 accommodates the non-cylindrical grinding process (e.g. cam profiles) or pin chase grinding (e.g. pin bearings).
Option: An additional station (station 3) permits all grinding processes, e.g. pivots or flanges.
