Machine Overview

In-house Metrology Lab

TGS recognizes the need to implement quality controls that exceed those of the centerless grinding machinery industry in general.   Aware of ever-increasing global quality standards, TGS continues to invest heavily in its in-house metrology laboratory, which recently added Carl Zeiss testing equipment, including: 

  • ACCURA 9/18/7 coordinate measuring machine (CMM)
  • RONDCOM 60AS for form measurements
  • SURFCOM 5000 for surface finish inspections.

One trip through our facility is normally all it takes to change a skeptical company into a devoted customer. Once they see our quality grinder manufacturing procedures in tandem with our management checks and balances it becomes an easy decision to partner with TGS. 

TGS performs a series of quality tests on every centerless grinding machine and documents and shares all results.  Whatever the official title of the TGS staff, each team member is entrusted to uphold our quality standards and manufacturing methods.

Contact TGS to arrange a tour of our facility or to learn more about our centerless grinding machines.

A "sound purchase," “rock solid,” and “a long-term investment” are terms that can be used to describe TGS’ CNC centerless grinding machine. Constructed with only the most heavy duty components, the TGS-CL-6020 centerless grinder provides long service life even in the toughest production environments.  You can be assured that the TGS centerless grinding machine is built to last.

Production requiring tight tolerance components will benefit from the TGS-CL-6020 CNC centerless grinder.  The machine offers sub-micron level precision, largely due to its high rigidity. 

Just a few of the many features of the TGS-CL-6020 CNC centerless grinding machine include:

  • Grinder machine bed is constructed from high quality cast iron that is stress relieved for lifetime accuracy and years of reliable, trouble-free operation. 
  • Integrated, heavy duty preloaded rolling guide ways speed cycle times and allow tighter tolerances.
  • A regulating wheel spindle incorporates high precision, greased-for-life roller bearings.
  • Outboard bearing support provides maximum spindle rigidity and extended operational life.
  •  Upper and lower slideways feature a micro-feed attachment for fine adjustment of less than 0.001mm.
  • A two-axis CNC grinding wheel dresser accommodates any part profile.

Finite Element Analysis (FEA)

Dynamic and static FEA was conducted on all critical grinder machine parts and subassemblies to ensure top-notch performance under demanding strength and stress requirements.
