The cylindrical peripheral surface of a rotating workpiece is ground by a first section of a rotating grinding wheel while a second section of the grinding wheel is used to simultaneously grind a thread into the peripheral surface so that the reduction of the diameter of the peripheral surface and the forming of a thread therein take place in one and the same operation.

Experiments are conducted on universal tool and cutter grinding machine with L9 Orthogonal array with input machining variables as work speed, grinding wheel grades and hardness of material. The developed model can be used by the different manufacturing firms to select right combination of machining parameters to achieve an optimal surface
The grinding performance is significantly affected by, the important parameters in the grinding machine like feed, depth of cut, work piece material. The effect of these parameters on the grinding machine is measured in terms of the surface finish produced on the work piece during subsequent grinding operation.
CNC 635 G Male thread grinding machine In addition to metric, Whitworth, trapezoidal threads and special profiles, the CNC 635 G also allows grinding of worm gears with shapes ZK, ZN, ZE and ZA wit...
Feb 15, 2017 As the name implies, centerless grinding involves the grinding of cylindrical parts without locating the part on a specific center line between centers. The centerless process is commonly used for high volume production, and its also easily used for low volume production because the machine setups are fairly simple.
Oct 16, 2019 6. It is found that to achieve minimum surface roughness of AISI 4140 steel, the parameters are grinding wheel speed of 2640 rpm, work-piece speed of 710 rpm, grain size 46 meshinch, depth of cut 15 m, concentration of cutting fluid 5 and number of passes 3.
Cylindrical grinding External cylindrical grinding, internal cylindrical grinding, contour grinding or thread grinding. Standardised cycles with parameter inputs or programmed cylindrical grinding operations are available. SCHNEEBERGER 5-axis machines use standard grinding wheels or specifically trued shaped wheels.

For tap thread grinding, ... Grinding Parameters. To establish the feed-rate vw, ... Load reading on a creep-feed grinding machine If the Amp meter is reading 20 of maximum load you may increase the feed-rate by steps of 20 steps, if the Amp reading is at 60, take 10 steps. Again, remember the aim is a stable process.
The TAPOMAT is characterized by high flexibility, short tooling times, easy operability and a minimal contact surface. A diamond roller single or multiple tooth is used to profile the relevant threaded grinding wheel. Diamond fliese tools are used for profiling the chamfer grinding wheel. This allows the machine to grind any optional thread ...

The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm about 30 to 35 msec. High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.

Dedicated Operation. Dedicated thread grinding machines have enabled Mechanitron Corp., Roselle, N.J., to serve a customer base that has continually changed over 5 decades.
Jan 11, 2017 For a cylindrical or surface grinder, the feed-rate is determined by the speed of the table. For a centerless grinder, the feed-rate is determined by the angle and rpm of the regulating wheel. For the grinding of most plastics, a suggested feed-rate is fourteen to thirty-two ftmin 4.27 to 9.75 mmin.
