Introduction: Flask production usually covers a family of bodies rather than a single item: pocket flasks, tumblers, travel bottles and wide-mouth jars may share the same surface treatment area.
Before considering automation, confirm that your current diameter and height mix fits the JSB-MP1135 double station seam grinding machine. The machine accepts 40–180 mm pipe diameters and 50–400 mm workpiece heights. Once that fit is clear, the inquiry can focus on fixtures, loading method, power supply and floor space.
Matching Flask Body Diameter and Height to the Machine Envelope
The JSB-MP1135 double station seam grinding machine works across a 40–180 mm pipe diameter range and a 50–400 mm workpiece height range. Test those figures against your production list, not against one sample. Pull the SKU master list or the last quarter's order records, sort by body diameter and then by height, and identify where most of the volume sits. A plant with output concentrated between 65 mm and 90 mm, plus a few 120 mm outliers, faces a different fixture plan from one running 45 mm pocket flasks alongside 180 mm wide jars. The extremes at both ends determine how many mold sets and changeovers the cell needs.
1. Diameter Range Determines Which Flask Bodies Need Dedicated Fixtures
Diameter drives tooling. The workpiece sits in a mold held by the pull-down rotary cylinder clamping device, so each diameter group needs a mold that locates the body precisely under the grinding head. Bodies between roughly 60 mm and 110 mm often cover the bulk of a flask catalogue and can share a small number of mold sets. A 42 mm slim body and a 175 mm wide jar sit at opposite ends of the same 40–180 mm range and will need different fixtures. For an inquiry, list every diameter in production with approximate monthly volume so the fixture plan reflects repeat demand rather than a single sample. When a CNC grinding machine manufacturer reviews that list, the discussion can move directly to mold sets and changeover sequence.
2. Height Range Sets the Loading Height and Operator Reach
Height shapes the working station. Between 50 mm and 400 mm, the operator loads and unloads at a different reach depending on the body, and the X/Z slide travel must clear the tallest workpiece in the mix. If your catalogue is mostly 90–140 mm tumblers with a handful of 350 mm travel bottles, plan the cell around the tumblers and treat the tall bodies as a separate batch run. Height also affects rhythm: short bodies load quickly, while tall bodies take longer to seat, and mixing them on one station slows the operator without slowing the machine. The 40–180 mm and 50–400 mm figures define what the machine accepts; cycle time still varies with part shape and size. Pick three representative bodies—one small, one mid-range and one at the top of your range—and ask for the grinding program and fixture plan to be discussed around those three before the order is placed. A welding grinding machine manufacturer can explain how the tallest body is clamped and how the grinding stroke clears it.
Checking Power, Footprint and Workshop Services for Installation
The machine draws 14 kW and accepts AC 380V/415V supply. Check the actual voltage at the panel that will feed the machine, not the nameplate of the transformer upstairs, and confirm the breaker rating, cable size and distance from the distribution board. A 14 kW connected load needs a check against available capacity; sharing a circuit with equipment that draws heavily during spindle start can cause nuisance trips. Confirm available capacity before the machine ships so the electrical work happens during installation, not weeks later. A vacuum flask line supplier can confirm these services against the installation plan before the equipment arrives. Physically, the machine measures 1600 × 950 × 1800 mm and weighs 1120 kg. Plan the route in before you plan the position. Check door width, the turning radius at the corner of the surface treatment aisle, and the floor condition for a 1120 kg machine. Around the footprint, allow working clearance on the loading side, room to reach the second station without the operator stepping behind the frame, and space for ducting from the high-power dust suction fan to your workshop exhaust point. The 1800 mm height also matters if the cell sits under a mezzanine or a low ceiling with services running across it. Send a simple floor plan with the machine position, panel location and dust route marked, and the installation questions can be answered before the machine lands.
Understanding the Clamping and Grinding Structure Behind Repeatable Results
Repeatable results on a seam grinder come from the structure, not from the operator's hand. The X/Z slide is mounted on an overall steel frame, and the moving elements run on HGH high-precision linear guideways. HIWIN's guideway documentation explains that assemblies of this type are designed for load capacity, rigidity and smooth travel; THK's slide table material covers positioning and rigidity under grinding loads. For this machine, those mechanical properties support a stable tool path as the grinding head follows the mouth or bottom seam. The same program can then produce a consistent edge from one body to the next. The sequence is simple: the operator seats the body in the mold, presses the start button, the pull-down rotary cylinder clamps the workpiece, the spindle turns, the X/Z axes feed in, the rotary automatic swing-angle grinding head follows the mouth or bottom seam, and the program returns everything to its start position. Servo plus PLC control runs that cycle, so stroke, feed and dwell are set in the program rather than judged by eye. This is the practical difference between the JSB-MP1135 double station seam grinding machine and a manual linishing station: contact pressure and path are controlled by the program, and the operator follows a start-and-clamp sequence instead of guiding the tool by hand. The dust suction fan pulls particulate at the source. The finish is a deburred, smooth mouth edge and a blended bottom seam with a stain finish—a clean satin look. Mirror polishing is a separate process. Nominal output is 10000 pcs/8h, and that figure depends on loading method, part size and abrasive condition. The double station configuration supports the nominal figure, but the same variables determine what a given flask mix will achieve. The value is in the consistency and the move from hand-guided grinding to a programmed cycle, both of which hold across the working range.
Conclusion
Start with the workpiece envelope, and the buying decision becomes simpler. Sort your flask bodies by diameter and height, mark where the 40–180 mm and 50–400 mm ranges cover your mix, and note the outliers that need their own fixture sets. Then confirm the 14 kW load against your panel, walk the route to the install position with the 1600 × 950 × 1800 mm footprint and 1120 kg weight in mind, and plan the dust ducting before the machine arrives. With diameter, height, power and space settled, the technical inquiry becomes a short, specific conversation. Send your body list with diameters, heights and monthly volumes, your supply voltage and a marked floor plan. JACKSON automatic production lines can review the fit and return a fixture plan and layout that matches your shop.
FAQ
Q: Does the JSB-MP1135 handle both 40 mm and 180 mm flask body diameters?
A: Yes. Its working pipe diameter range is 40–180 mm, so both 40 mm and 180 mm bodies fall within the envelope. Each diameter group still needs a suitable mold for the pull-down rotary cylinder clamping device; a 40 mm slim body and a 180 mm wide jar will use different fixtures. Provide the full diameter list with volumes so the fixture plan can be prepared before the order.
Q: What workshop power supply is required for a 14 kW double station seam grinding machine?
A: The machine runs on AC 380V/415V supply with a 14 kW connected load. Check the actual voltage at the panel that will feed it, along with breaker rating, cable size and distance from the distribution board. Avoid sharing that circuit with equipment that draws heavily during spindle start. Confirm available capacity before shipment so the electrical work fits inside the installation window.
Q: How should a team test whether 50–400 mm workpiece height fits the loading method?
A: Take the three tallest and three shortest bodies in production and walk through the loading motion at the station height you plan to use. Check that the operator can seat each body in the mold without strain, that the X/Z travel clears the tallest workpiece, and how long each body takes to load. Then decide which heights run as a batch and which can mix, because loading rhythm often limits real output more than the envelope does.
