Complete interpretation of quality drill bits second development

CNC deep hole drilling ( gun drill ) in recent years developed a deep hole

machining new technology. The traditional deep GUSHI circular blades  hole machining ( hole depth

and aperture ratio greater than 5 ) , requires drilling, boring , thick

hinges , grinding , and other procedures in order to process a higher

accuracy and lower surface roughness of the hole . The new technology is

the use of special tools and high-pressure structure of cooling and

lubrication systems , multi-channel processes described above can be

simplified to a considerable depth consecutive passes completed high

precision and low surface roughness of hole machining , high efficiency of

this process , significant economic benefits .
Excellent performance cutting fluid deep hole drilling deep hole drilling

process is one of the key technologies , deep GUSHI carbide drill bits  hole drilling cutting fluid

must have the following properties:
1 ) good cooling effect, eliminating the heat generated due to the

deformation and friction , inhibiting BUE formation.
2 ) Good high temperature lubrication, reducing friction and wear blade

and support to ensure the tool to maintain good lubrication at high

temperature cutting zone .
3 ) good permeability , chip , so that timely cutting fluid penetration

into the blade, and to ensure the smooth chip discharge . Thus , deep hole

drilling cutting fluid requires a high extreme pressure and low viscosity.
Mechanical products, styling products series occupies a large proportion .

Mostly the same series of styling products have the same or similar

contour features in traditional modeling methods for product design,

inevitably the model geometry the size and shape of the structure

repeatedly modified , adjusted and optimized , low design efficiency. In

order to improve design efficiency , styling products for serialization ,

you can use the parametric design method . Parametric design is the use of

a set of parameters to constrain the geometry of the product model , in

order to facilitate the realization of the variability of the product

model , design reusability and fast it can shorten the  GUSHI brick saws design and

development cycle and improve design efficiency , freeing the designer

from the tedious modeling work, put more energy into the model analysis ,

and improvement of innovative work, for subsequent finite element analysis

and formulation process ready to work .
The most widely used in the drilling of the twist styling products also

belong to the series , the same type of high-quality twist drill has

structural features are similar , but differ in terms of size parameters.

Based on high-quality drill design software , call the API target for

secondary development to achieve the parametric modeling of complex

spatial design twist front surface flank , flank , flutes and cutting edge

Ropes diamond core drills into Coring advantage

Coring Drilling Coring advantages:
1 auxiliary reducing tripping time, increasing net drilling time, drilling deeper economic effect is more significant;
2 core blockage can gain immediate, rock cores taken to improve the rate;
(3) reduce the manual workers;
4 screwed reduce unloading drill wear and  GUSHI tile cutter extend the life of the drill pipe, tubing reduce consumption;
5 Reduce sweep drill hole wear, unscrew and remove the chance of collision with the hole wall. Extend bit life;
6 reduce fluid suction and pressure loss of balance hole wall opportunity to reduce accidents hole;
7 reduce tripping rope mechanical wear and consumption;
8 reduce drilling bending, improve the quality of drilling;
9 drilled repeatedly in favor of the formation, to avoid the collapse of the hole wall blocks away;
10. Coring winch rope can devolve inclinometer in the drill, conducted inclinometer.
In short, Coring, can significantly GUSHI brick saws  improve drilling efficiency, ensure quality rock cores, reduce drilling costs. Coring Drilling need to have the condition:
In the core drilling, the realization Coring, you must have the following major technical conditions:
1 reasonable structure, reliable performance, including core drilling with salvage, positioning, suspension, messenger, single-action, de-regulation and security cards and other agencies rope core core tube and fisher;
2 Action flexible, durable tool ancillary equipment, including drill pipe holder, put lead, a coring winch rope, etc.;
3 high intensity inside and outside the flat drill with drill body and after quenching, the appearance of high-frequency hardening, hard chrome plating composed of male and female threaded joints;
4 long life and high efficiency of the diamond drill bit, the species has stepped table inlaid natural diamond drill bits, different lip surface shapes and natural progesterone diamond head table inlaid with a  GUSHI cutting disc for drill combination of impregnated diamond bits;
5. Adopt reasonable rules and coring drilling process technique.

Some of the major introduction of diamond core drills

First, what is the drill
Is used to drill a workpiece to drilling tools.
Drill generally just (W18Cr4V or W9Cr4V2) made of high-speed, divided twist, flat drill, center drill, countersink hole drilling, deep hole drilling, which is our twist fitter, machining the most common drill.
This is a paper I have to talk about is the main method of twist drill sharpening its restructuring. I began to talk about from the GUSHI sds hammer drill bits  twist, first introduces the basic knowledge under twist.
Twist the type and structure:
Straight shank twist drill into, Morse taper shank. Generally straight shank twist drill diameter 13mm or less in diameter Morse taper shank twist drills are in 13mm or more. Typically the twist handle, neck, working part, wherein the working portion and the guide portion, the cutting part. Specifically as shown in Figure
(A) the handle - is generally used to transfer the clamping force and a smaller diameter than Φ13 mm straight shank drill made it, no clear straight shank drill neck, the diameter of the drill, trademark etc. engraved on the handle directly. Φ13 mm and a diameter greater than generally made taper shank drills, taper shank drills taper is produced according to national standards, according to the size of the drill diameter and made Mohs 1 #, 2 #, 3 #, 4 #, 5 #, etc. taper, the larger the size of the handle numeral greater. Flat tail taper the ends for easy removal and transfer torque from the drill bit role.
(2) Neck - The neck is connected to the  GUSHI cutting disc for drill handle portion and a portion of the work, but also for the grinding wheel retraction drill is used, the diameter of the drill itself, materials and trademarks are engraved on the neck.
(3) working part - it is divided into two parts ① cutting guide and the guide portion twist to the right direction to keep working, and when re-sharpening drill bits, cutting guide portion and gradually become part and to work. The guide portion has two parallel helical grooves, is to be formed to accommodate the cutting edge and the removal of the chips and facilitate the input of the cutting fluid. There are two edges with a guide portion, its diameter is slightly inverted cone, every 100mm length, shank diameter is reduced to 0.05-0.10mm, both to guide the direction of the drill bit cutting, but also can reduce the drill hole wall friction. ② a key part of GUSHI abrasive flap wheels  the cutting portion of the drill bit, the flank twist of six, five blade consists of: a rake face comprising two, two rear flank, two sub behind the two main cutting edges, two auxiliary cutting edge , a horizontal edge, namely "a sharp three blade." As shown in Figure
Through these two points, I believe we have fully understood the basics of the drill point, so I can deeper introduce myself sharpening methods and steps up.
Twist mainly by cutting part of the cutting, but we have to start from the drill bit is also part of the transformation. Start sharpening my own way to start talking.
