How to polish and maintain injection molds?JasmineHL
The polishing described in plastic mold processing is very different from the surface polishing required in other industries. Strictly speaking, the polishing of the mold should be called mirror processing. Not only does it have high requirements for polishing itself, but it also has a high standard for surface flatness, smoothness, and geometric accuracy. Surface polishing generally requires only a shiny surface.
The abrasive jet can be used to cut any material. Even diamonds have been cut, using diamond dust as the abrasive.
Make all sort of shapes with only one tool.
Virtually no heat is generated in the work piece.
No mechanical stress.
Fast set up.

GMT started manufacturing lapping & polishing machine in 1971. It was built for in-house use and until then hand lapping process was used for finishing surface plates. Critical parts for our workholding devices required a finishing and buffing machine. There was demand in the market for valve lapping and lapping plates. Since GMT had a captive ferrous foundry, castings for lap plate and lapping machine were easier to source.
Since then GMT has become one of India's largest lapping machine manufacturers and suppliers with over 350 installations throughout India mainly to the valve and pump industry. When a buyer in Japan wanted a super finishing machine for lapping large granite plates, GMT designed and supplied a 3000mm dia flat lapping machine.
Pump manufacturers, electronic industries, valve manufacturers, etc., have found a sure way of obtaining positive sealing.
Peel grinding is a process that enables one machine to perform several grinding operations without removing the workpiece from the machine. Junker Machinery (Springfield, Massachusetts) uses this process on a line of machines it calls Quickpoint.
Advance machining processes are used where higher accuracy and surface finish is required. One of them, Abrasive jet machining is a non-traditional machining process in which a high-pressure air stream and abrasive particles impinge on a work surface through a nozzle. Abrasive jet machining (AJM) removes material through the action of a focused beam of abrasive jet directed at the workpiece the resulting erosion can be used for cutting, drilling and debarring etc. With the increase of needs for machining of ceramics, semiconductors, electronic devices and L.C.D., AJM has become a useful technique for micromachining. it is more useful in industries for precision work. Material removal rate during this process affected by different parameters like abrasive particle size, the velocity of abrasive flow rate, gas pressure, standoff distance etc.

1.Grinding Automotive Parts-Camshaft and Crankshaft
2.Application of CBN Grinding Wheel in Internal Hole Grinding
3.Using CBN Wheel for Grinding Gear
4.Application of CBN abrasive tools to process hard materials and hard surface
How to dress vitrified CBN wheels?The dressing of CBN grinding wheel can be divided into two steps: Truing and Dressing. Truing is to make the grinding wheel reach the required geometric shape and dimensional accuracy by changing its macroscopic shape of the grinding wheel, and make the grinding wheel tip finely broken to form a sharp grinding edge; Dressing is to remove the binder between the grinding grains of the grinding wheel, so that the grinding grains protrude from the surface of the binder, forming the necessary chip space so that the grinding wheel has the best grinding capacity. According to the specific situation, shaping and sharpening can be unified or completed at the same time, also can be done step by step.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

How to perform“mirror grinding” ?
More Super Hard Products Co., Ltd19
what is mirror grinding?
The surface roughness Ra< 0.01µm and the flatness plane is< 3µm/1000mm after the
workpiece grinding.
Method of mirror grinding
1. Balance and dressing grinding wheel
1) Balance the grinding wheel. After the grinding wheel is installed with the flange, the first
static balance is performed, and then the end face and outer circle are trimmed on the
grinding wheel shaft and then the precise static balance is performed.
(2) Dressing the grinding wheel.
The dressing of the grinding wheel directly affects the smoothness of the grinding surface.
Pay attention to the following matters when dressing the grinding wheel:
1) The general fine grinding allowance is 0.015~0.02mm. When the workpiece is coarsely
ground to Ra0.8, the fine grinding allowance is 0.005~0.015mm (the remaining grinding
allowance must be determined according to the nature and hardness of the steel. The
steel with high hardness and easy to be polished should have less grinding allowance),
then the grinding wheel needs to be refined.

Tel/WhatsApp: +86 15617785923 Email: Anna.wang@moresuperhard.com
2) When fine processing the grinding wheel, first grind off the thickness of 0.1mm, then
dressing it twice with 0.02mm depth of cut , then dressing three times with 0.01mm depth
of cut, and finally reciprocate twice without the depth of cut.
During fine processing, the lateral feed speed is 20~30mm/min. For mild steel workpieces,
it is better to slow the lateral feed when grinding the grinding wheel, and the opposite is
true when processing hardened high-speed steel.
3) While dressing the grinding wheel, sufficient grinding fluid must be used to flush away
the grinding wheel debris in time to avoid affecting the grinding quality.
4) The diamond tools used in finishing does not need to be very sharp, because the grain
size of the grinding wheel is relatively coarse. The diameter of the diamond tip can be
within 0.8mm. When dressing with sharper diamond tools, the traverse feed speed must
be slowed down.
5) When the newly-dressed grinding wheel is used, the surface roughness is slightly
worse, and it will stabilize after a while.
2. Grinding amount

1) The amount of tools on the back of the grinding wheel is about 0.005 mm. Appropriate
increase or decrease according to the nature and hardness of the workpiece steel. For
example, hardened steel with high hardness can easily cause burns with more cutting
feed.
2) The single stroke of the horizontal feed is 0.2~0.4mm. The speed of the lateral feed has
a greater influence on the surface roughness, because the grinding wheel for mirror
grinding has poor cutting ability. If the lateral feed speed increases, the surface of the
grinding wheel will be damaged, so very smooth surface cannot be obtained.
3) The longitudinal feed rate is 12~15 m/min. The longitudinal feed has a relatively small
effect on the surface roughness, but if it is too slow, the surface of the workpiece will
produce ripples or patterns.
4) No-cut deep polishing. The tool marks often appear due to the poor cutting ability of the
grinding wheel during mirror grinding, which reflect the uneven surface of the workpiece,
so no-feed smooth grinding is required about two minutes.
