Most factories engaged in precision grinding share a common misconception: they blindly upgrade to high-end grinders and premium grinding wheels, yet overlook the unassuming workholding supports.

Often, issues such as workpiece dimensional drift, end face warping, batch tolerance instability, and grinding burns are not due to machine tools or grinding wheels, but rather hidden dangers stemming from long-term pressure-induced deformation and wear-induced sinking of support fixtures.

As the "invisible foundation" of grinding processes, the rigidity, wear resistance, and thermal stability of supporting fixtures directly determine the dimensional accuracy of entire batches of workpieces. Traditional steel and carbide supports can no longer meet the current demands of micron-level mass production. Meanwhile, Henan Shili Diamond Supports are becoming the standard fixtures for precision grinding of small components such as shafts, pins, nozzles, and needle rollers, addressing factory precision shortcomings.

1. Traditional support systems suffer from three major flaws, dragging down the overall plant processing yield

After visiting hundreds of precision grinding factories, we found that ordinary supports commonly have intractable industry pain points

- Prone to deformation under force: Continuous high-speed grinding under pressure causes the supporting contact surface to slowly collapse, resulting in height deviations exceeding 0.008mm per day of processing, with inconsistent dimensional variations among workpieces from the same batch;

Poor heat resistance leading to overheating: Thermal expansion occurs during high-temperature grinding, resulting in wavy surfaces and burn marks on the workpiece end face, which maintains a consistently high rate of rework;

- High replacement frequency: Hard alloy supports require grinding and leveling every 15-20 days on average, leading to frequent downtime adjustments and significant loss of effective production time.

The seemingly minor support error, when amplified by machine tool grinding, directly leads to non-compliant orders and failed access to high-end supply chains, with hidden costs continuously rising.

II. Hard Data Speaks, Diamond-Supported Full-Spectrum Domination Over Traditional Workwear

Leveraging the ultra-high hardness and thermal conductivity advantages of diamond, Henan Shili has independently developed diamond supports, fundamentally addressing deformation, heat generation, and wear issues from the material source. Measured comparative data clearly demonstrates the results

✅ Ultimate deformation resistance, zero height offset

Diamond boasts the highest Mohs hardness, with compressive strength far surpassing conventional alloy materials. Under continuous 24-hour uninterrupted grinding conditions, its support height error remains ≤0.0015mm, exhibiting nearly zero plastic deformation. Compared to cemented carbide supports, it achieves over 85% improvement in dimensional stability, completely eliminating workpiece reference drift issues.

✅ Excellent thermal conductivity and heat dissipation, eliminating grinding burns

Diamond exhibits significantly higher thermal conductivity than copper, rapidly dissipating high temperatures at the grinding contact surface and reducing workpiece surface temperature by 40%. It is perfectly suited for precision grinding of hard and brittle materials, stainless steel, and small alloy components, maintaining stable surface roughness within Ra0.2 without requiring secondary polishing.

✅ Extended service life, significantly reduced costs

Ordinary alloy supports require grinding 2-3 times per month and must be fully replaced every 3 months. In contrast, Henan Shili diamond supports can achieve a maintenance-free service life of up to 18 months under normal operating conditions, extending lifespan by over 6 times and significantly reducing downtime for adjustments and tooling procurement costs.

3、 Seiko self-developed customization, suitable for all scenarios of precision grinding conditions

The universal diamond supports on the market often have poor adaptability and are prone to problems such as insufficient adhesion and inaccurate positioning. Henan Shili has been deeply involved in the field of superhard tooling for many years, refusing to standardize products across the board and insisting on customized non-standard products according to demand.

Relying on five axis precision machining equipment and three coordinate full inspection technology, we can accurately match the support angle, contact surface curvature, and positioning dimensions according to the outer diameter of the workpiece, grinding stroke, and machine model. The product's factory profile tolerance is strictly controlled within ± 0.002mm.

Simultaneously optimizing the diamond layer arrangement process, combined with high-strength alloy steel substrate, balancing rigidity and toughness, during high-speed reciprocating grinding process, there will be no diamond particle detachment, surface peeling or other faults, suitable for mainstream grinding equipment such as centerless grinding, external cylindrical grinding, and end face grinding.

4、 Factory real case: Changing to a different set of support directly increases yield by 5.2%

A precision needle rolling processing enterprise in Jiangsu has been using hard alloy support for a long time, resulting in large errors in workpiece cylindricity and a batch yield rate of 93.5%. After replacing the Henan Shili diamond support:

1. The cylindricity error of the workpiece is stably controlled within 0.003mm;

2. The batch yield rate has been increased to 98.7%;

3. Reduce downtime and calibration time by 12 hours per month, and increase monthly production capacity by 7%;

4. The annual average cost of tooling consumables is directly reduced by 40%.

Many factories spend a lot of money upgrading their machine tools, but neglect to support this crucial small component. In fact, breakthroughs in precision machining are often hidden in the upgrading of detailed fixtures.

The competition in precision manufacturing has entered a white hot stage, and in addition to assembling equipment and processes, it is even more important to assemble every detail of the tooling.

Henan Shili Diamond Support uses domestically produced hard core and superhard technology, with real and measurable data and long-term stable quality, to solve the three major pain points of unstable grinding benchmarks, accuracy drift, and high consumables. It helps major precision machining factories easily improve machining accuracy and mass production efficiency without requiring large equipment investment, and firmly holds the bottom line of precision in high-end manufacturing.
